'local.db' depending on expected prefix) so drizzle.config.ts uses the same DB_PATH env var as buildDbIndex and buildMigrateScript.

15-15: Consider upgradingzodto v4 for new project scaffoldsThe library documentation bundled with this review covers Zod 4, which ships substantial improvements over Zod 3.23.8 (unified error customization, safer number/string validation, major performance gains for complex schemas, and a modular architecture). Since this is a starter template, scaffolded projects will be born on Zod 3 unless updated here.

Inline comments:
In `@betterbase/apps/cli/tsconfig.json`:
- Around line 10-15: Add the "jsx" compiler option to the base TypeScript
config: open tsconfig.base.json and under "compilerOptions" add "jsx": "react"
(or "react-jsx" if using the new JSX transform) so .tsx files included by the
globs are compiled correctly; ensure the option is placed at the same level as
"strict" and saved so this CLI tsconfig inherits it.
In `@betterbase/package.json`:
- Line 13: The package.json "typecheck" script uses POSIX single-quotes which
break on Windows (the entry is the "typecheck" npm script); update the script to
use cross-platform quoting or a helper: replace "--filter '*' " with a
Windows-friendly form such as --filter "*" (escaped as \"*\" inside the JSON
string) or switch to a cross-platform wrapper (e.g., use cross-env or Bun's
shell workaround) so Turbo receives --filter * correctly on both Unix and
Windows.
In `@betterbase/packages/cli/src/commands/auth.ts`:
- Around line 46-66: The signup and login handlers currently call
signupSchema.parse() / loginSchema.parse() which throw ZodError and result in
unstructured 500 responses; change to use signupSchema.safeParse(await
c.req.json()) and loginSchema.safeParse(await c.req.json()), check
result.success, and if false return a 400 JSON response with the validation
errors (e.g., result.error.format() or result.error.errors) instead of
proceeding to password hashing/db operations (symbols to update:
signupSchema.parse -> signupSchema.safeParse, loginSchema.parse ->
loginSchema.safeParse, and the authRoute.post('/signup') / login handler flows
that use the parsed body and Bun.password.hash/db.insert(users)...).
- Around line 136-147: The validateSession function is returning the full users
row (including passwordHash); change the DB query in validateSession to select
only the allowed fields (id, email, name) from the users table (instead of
db.select().from(users)) and return that sanitized object (or map the returned
row to an object containing only id, email, name) so the passwordHash is never
placed on the auth context; update any references to session/user retrieval in
validateSession to use the specific column selections from users and return null
if no user.
- Around line 59-65: The response currently dereferences created[0] without
checking it, which can throw if .returning() yields an empty array; update the
handler that builds the response (the code that calls c.json and uses
created[0].id/email/name) to first guard that created[0] exists and is an
object, and if not return a safe error response (e.g., 500/appropriate error
with a descriptive message) or throw a handled error; ensure you reference
created[0] only after the guard so the c.json payload uses validated values.
- Around line 252-267: The ensureRoutesIndexHook function currently attempts to
inject an import and route by replacing specific anchor strings and then always
writing back the file (writeFileSync), which can corrupt the file if those
anchors are missing; update ensureRoutesIndexHook to detect whether each anchor
("import { usersRoute } from './users';" and "app.route('/api/users',
usersRoute);") is present before calling .replace(), and if either anchor is
missing do NOT overwrite the file — instead log or print a clear warning
indicating which anchor(s) were not found and that automatic injection was
skipped; alternatively (preferred) implement a safe append fallback that adds
the import at the top imports block and the route in a sensible location only
when anchors are absent, but ensure you reference ensureRoutesIndexHook,
routesIndexPath, current, and writeFileSync in your changes so the function no
longer silently corrupts output.
In `@betterbase/packages/cli/src/commands/generate.ts`:
- Around line 188-191: The relative path used to compute canonicalRealtimePath
is one level short; update the path string passed to
path.resolve(import.meta.dir, ...) from
'../../../templates/base/src/lib/realtime.ts' to
'../../../../templates/base/src/lib/realtime.ts' so canonicalRealtimePath points
to betterbase/templates/base/src/lib/realtime.ts and keep the existsSync/catch
logic as-is (refer to the canonicalRealtimePath variable and the existsSync
check and thrown Error message).
In `@betterbase/packages/cli/src/commands/migrate.ts`:
- Around line 265-270: splitStatements currently splits on every semicolon which
will break SQL string literals; update the splitStatements function to iterate
the SQL string char-by-char, track quote context (single quote ', double quote
", and backtick `) and escape sequences so you only treat semicolons as
statement delimiters when not inside a quoted context, accumulate characters
into the current statement, trim and push non-empty statements at semicolon
boundaries outside quotes, and ensure it handles escaped quotes and doubled
single-quote SQL escaping; alternatively if you prefer to accept the risk, add a
clear comment above splitStatements documenting the assumption that input is
generated by drizzle-kit and will not contain semicolons inside string literals.
In `@betterbase/packages/cli/src/utils/scanner.ts`:
- Around line 148-168: collectFromObject currently inspects only the outer
CallExpression name so chained calls like index(...).on(...) return "on" and
never match; update collectFromObject to walk the call chain (unwrapExpression
-> while ts.isCallExpression(value) { name = getCallName(value); if name ===
'index' || name === 'uniqueIndex' { add key to indexes and break } value =
value.expression } ) similar to parseColumn's chain traversal, using
getCallName, unwrapExpression and the existing key extraction logic to detect
index/uniqueIndex anywhere in the chain before pushing into indexes.
- Around line 88-91: The scan() loop currently keys the tables map by the
TypeScript identifier (declaration.name.text) causing mismatches; change it to
first call this.parseTable(initializer) into a local tableObj, then use the
table's SQL name (e.g., tableObj.name or tableObj.tableName — whichever
parseTable returns) as the key in tables[...]=tableObj instead of
declaration.name.text; keep a fallback to declaration.name.text only if the
parsed table object lacks a name. Ensure references to getCallName(initializer),
parseTable(initializer), initializer, declaration.name.text and the tables
variable are updated accordingly.
In `@betterbase/templates/base/package.json`:
- Around line 10-11: The template's build/start scripts ("build": "bun build
src/index.ts --outfile dist/index.js --target bun" and "start": "bun run
dist/index.js") emit artifacts to dist/index.js but the template folder lacks a
.gitignore, causing generated projects to accidentally commit build outputs; add
a .gitignore file to the template directory containing at minimum the lines for
dist/, node_modules/, and .env so build artifacts and dependencies are ignored
(place the .gitignore alongside the package.json in the template).
In `@betterbase/templates/base/README.md`:
- Around line 37-38: The README references scripts that don't exist in the
generated package.json; update the generator or the docs: either add "build" and
"start" entries to the package scripts created by buildPackageJson in init.ts
(e.g., map to the existing production build/start commands used by the project)
or remove the "bun run build" and "bun run start" lines from
betterbase/templates/base/README.md so docs match the scripts (ensure
package.json produced by buildPackageJson contains dev, db:generate, db:push
plus any newly documented scripts).
In `@betterbase/templates/base/src/db/migrate.ts`:
- Around line 4-7: The migration script in migrate.ts currently opens the DB
with DEFAULT_DB_PATH (symbol DEFAULT_DB_PATH) which is always 'local.db' and
therefore diverges from the validated env path used by db/index.ts; update
migrate.ts to import and use the validated env.DB_PATH (or the exported env
object/property) when constructing the Database instance so migrations run
against the same DB as the app (replace DEFAULT_DB_PATH usage with env.DB_PATH
or equivalent exported validated value).
In `@betterbase/templates/base/src/index.ts`:
- Line 2: The WebSocket setup lacks the required websocket handler: import
websocket from 'hono/bun' alongside upgradeWebSocket and pass the websocket
object into the Bun.serve call; update the import to include websocket and
ensure Bun.serve({ fetch: app.fetch, websocket, port: env.PORT, development: ...
}) so upgradeWebSocket (used on routes like app.get('/ws',
upgradeWebSocket(...))) can function correctly.
In `@betterbase/templates/base/src/lib/realtime.ts`:
- Around line 31-37: handleConnection currently accepts and registers any
ServerWebSocket without authentication and subscribe allows any table
subscription; add token-based authentication during the WebSocket upgrade
(inspect headers or Hono context) and validate the token before calling
handleConnection so only authenticated identities are stored in this.clients
(attach a userId/claims field to the stored client object). In the subscribe
method, lookup the client's identity from this.clients and perform an
authorization check against the requested table (e.g., call an authorize(userId,
tableName) helper or validate claims/scopes), and only add to
client.subscriptions if authorization succeeds; if auth or authorization fails,
close the socket or send an error message. Ensure errors are logged via
realtimeLogger and avoid registering unauthenticated clients by modifying the
upgrade flow that creates ServerWebSocket to reject or terminate connections
without valid tokens.
- Around line 39-62: handleMessage currently parses rawMessage with JSON.parse
and a blind type assertion instead of Zod validation; replace the JSON.parse +
"as" approach with a Zod schema (e.g., messageSchema with union of {type:
'subscribe'|'unsubscribe', table: string, filter?: Record<string, unknown>}) and
use messageSchema.safeParse or parse to validate the incoming payload, then
branch to subscribe(ws, ...) or unsubscribe(ws, ...) using the typed result; on
validation failure call safeSend(ws, { error: 'Invalid message format', details:
<validation errors> }) rather than the bare catch, and ensure references to
handleMessage, subscribe, unsubscribe, and safeSend are updated to use the
validated/typed data.

Outside diff comments:
In `@betterbase/packages/cli/src/commands/init.ts`:
- Around line 102-128: buildDrizzleConfig currently sets the local Drizzle URL
from process.env.DATABASE_URL which is inconsistent with
buildDbIndex/buildMigrateScript that use DB_PATH; update the databaseUrl mapping
inside buildDrizzleConfig (the local key in the databaseUrl record) to derive
the SQLite URL from process.env.DB_PATH (e.g. use process.env.DB_PATH ?
`file:${process.env.DB_PATH}` : 'file:local.db' or at minimum
process.env.DB_PATH ?? 'local.db' depending on expected prefix) so
drizzle.config.ts uses the same DB_PATH env var as buildDbIndex and
buildMigrateScript.
---
Nitpick comments:
In `@betterbase/packages/cli/package.json`:
- Around line 19-20: Update the production dependency version for "typescript"
in package.json to a narrower, safer range (e.g., change "typescript": "^5.3.0"
to "typescript": "^5.8.0" or a specific minor like "5.8.x") so the CLI's runtime
use of the TypeScript compiler API (used by route-scanner.ts and scanner.ts)
isn't affected by unexpected breaking changes; ensure the dependency stays in
"dependencies" (not devDependencies) and run install to update lockfile.
In `@betterbase/packages/cli/src/commands/auth.ts`:
- Around line 193-207: The regex in ensurePasswordHashColumn that finds the
users sqliteTable block (currently
/export\s+const\s+users\s*=\s*sqliteTable\([^]+?\}\);/m) can over-match or
truncate when the table body contains nested braces or embedded "});" sequences;
replace the fragile regex with a robust scanner: locate the sqliteTable( start
(in ensurePasswordHashColumn) then iterate characters counting opening and
closing parentheses/braces until you find the matching closing sequence for the
sqliteTable call, extract that exact block, perform the passwordHash injection
into that block, and write the file—this avoids relying on [^]+? and ensures
correct matching even with nested objects or composite index blocks.
In `@betterbase/packages/cli/src/commands/generate.ts`:
- Around line 85-95: The generated filtering logic in generate.ts allows any
property on the Drizzle table (variable tableName) to be used as a query filter
via filters -> conditions -> query.where, which can expose sensitive columns;
update the generator to either (A) restrict filters to an explicit allowlist:
compute a filterableColumns array (from the schema scanner or a new column
annotation like "filterable") and replace the runtime check (current key in
${tableName}) with membership in filterableColumns, or (B) if you prefer not to
enforce it now, inject a clear comment into the generated code near the
filters/conditions block warning that all columns are filterable and
recommending adding a filterable annotation in the schema scanner to exclude
sensitive columns; reference the symbols tableName, filters, conditions, and the
schema scanner/column annotation when making the change.
- Around line 197-216: The ensureZodValidatorInstalled function currently always
spawns `bun add` which wastes time; first check if `@hono/zod-validator` is
already present by looking for node_modules/@hono/zod-validator (using
fs.existsSync with projectRoot) or by reading projectRoot/package.json and
checking dependencies/devDependencies for "@hono/zod-validator", and only run
the Bun.spawn install block if neither check indicates the package is installed;
keep existing logging and error handling in the install branch and return early
when the package is detected.
- Around line 74-107: Replace the ad-hoc Number(...) pagination with the same
Zod-validated pagination flow used in users.ts: parse query via paginationSchema
(use MAX_LIMIT to cap), set fetchLimit = Math.min(limit, MAX_LIMIT) and request
fetchLimit + 1 rows from the DB, derive hasMore = items.length > fetchLimit and
then slice to fetchLimit before returning; include hasMore in the response and
do not return count: items.length (either run a separate total-count query if
you need a total row count or omit/rename the count field) — update the
generated route around the current limit/offset/safeLimit logic and the final
response to use paginationSchema, MAX_LIMIT, hasMore, and the limit+1 fetch
pattern.
In `@betterbase/packages/cli/src/commands/init.ts`:
- Around line 254-270: The migration script returned by buildMigrateScript
currently uses process.env.DB_PATH directly; update buildMigrateScript to import
and use the validated env export (e.g., import { env } from './env' or the
project's env module) and replace process.env.DB_PATH with env.DB_PATH so the
script uses the same validated/defaulted DB_PATH as other code (same pattern as
buildDbIndex); ensure the returned string references env.DB_PATH and that the
env import symbol is present in the file where buildMigrateScript is defined.
- Around line 300-308: The generated db index is using process.env.DB_PATH
directly which bypasses the validated env module; update the file that exports
db (the client/Database creation and exported db like the const client and
export const db) to import your validated env object (env) from the generated
src/lib/env.ts and use env.DB_PATH (falling back to a sensible default like
'local.db' only if env.DB_PATH is absent) when constructing the new Database, so
the Database(...) call and exported db/drizzle initialization rely on the
validated env.DB_PATH rather than process.env.DB_PATH.
- Around line 530-545: Add an explicit inline comment above parseNonNegativeInt
explaining that returning the provided fallback for undefined, non-integer, or
negative inputs is intentional behavior for permissive query-param handling
(e.g., "?limit=-5" or "?limit=abc") rather than a missing validation; reference
DEFAULT_LIMIT/DEFAULT_OFFSET/MAX_LIMIT as the expected fallbacks and note that
callers should validate and return a 400 if stricter behavior is required.
In `@betterbase/packages/cli/src/commands/migrate.ts`:
- Around line 272-297: The generate step in collectChangesFromGenerate (using
runDrizzleKit and DRIZZLE_DIR) creates persistent migration files which are only
used for analysis via analyzeMigration and splitStatements, while the subsequent
push flow applies schema changes directly and never marks those files as
applied; update the migrate command to surface a clear CLI notice (using the
same command path that calls collectChangesFromGenerate and push) stating that
"drizzle-kit generate" produced migration files in drizzle/ for preview only and
that push (not migrate) was used to apply changes, and optionally add a short
README/doc comment about this behavior so developers know generated files are
not auto-applied.
In `@betterbase/packages/cli/src/constants.ts`:
- Around line 1-2: DEFAULT_DB_PATH is duplicated across packages and kept in
sync only by a comment; extract this constant into a shared location and import
it where needed to avoid divergence: create a small shared constants module
(e.g., a new package or a shared utils file) that exports DEFAULT_DB_PATH,
update betterbase/packages/cli/src/constants.ts to import DEFAULT_DB_PATH from
that shared module instead of redefining it, and update
templates/base/src/lib/env.ts to import the same shared export so both consumers
reference the single source of truth.
In `@betterbase/packages/cli/src/index.ts`:
- Around line 62-81: The three commands registered as top-level commands
('migrate', 'migrate:preview', 'migrate:production') should be transformed into
a single parent migrate command with subcommands so they behave as "bb migrate
preview" / "bb migrate production" like the existing auth/generate pattern;
create a parent command for 'migrate' (with its description) and move the
current handlers into subcommands (e.g., 'preview' and 'production') that call
runMigrateCommand({ preview: true }) and runMigrateCommand({ production: true })
respectively while keeping the default subcommand to call runMigrateCommand({})
for plain "migrate".
- Around line 31-37: The action handler for the "dev" command awaits
runDevCommand(projectRoot) but discards its returned cleanup function, so file
watchers/timers never get torn down; change the .action handler to capture the
Promise<() => void> result (e.g. const cleanup = await runDevCommand(...)), then
register process signal handlers (SIGINT, SIGTERM and/or 'exit') that call the
captured cleanup and remove the handlers after invocation; ensure you also call
cleanup in a finally or on unhandled rejections so watchers are closed
gracefully — referenced symbols: program.command(...).action, runDevCommand, and
the returned cleanup function.
In `@betterbase/packages/cli/src/utils/context-generator.ts`:
- Line 47: Replace the bare console.log call that prints the success message in
context-generator.ts (the line using console.log(`✅ Generated ${outputPath}`))
with the project's logger API (e.g., logger.success or logger.info) to match
other files like dev.ts/generate.ts/migrate.ts; keep the same message content
and emoji but call logger.success(`✅ Generated ${outputPath}`) (or logger.info
if that is the established pattern) so logging is consistent across the CLI.
In `@betterbase/packages/cli/src/utils/route-scanner.ts`:
- Around line 108-142: The httpMethods Set is being recreated on every call to
the visit function; hoist it out of visit to avoid repeated allocations. Move
the declaration const httpMethods = new
Set(['get','post','put','patch','delete','options','head']) to the outer scope
of the module (above the visit function) and update visit to reference that
hoisted httpMethods; keep all existing logic around method extraction
(node.expression.name.text, method.toUpperCase()), route construction
(RouteInfo) and route pushing unchanged.
In `@betterbase/packages/cli/src/utils/scanner.ts`:
- Around line 4-19: Add Zod schemas for ColumnInfo and TableInfo and use them to
validate the scanner output: define zod schemas (e.g., ColumnInfoSchema,
TableInfoSchema, and TablesRecordSchema) and derive the TypeScript types via
z.infer for ColumnInfo and TableInfo; then validate the result of scan() (or any
function producing the tables record) by calling parse or safeParse on the
TablesRecordSchema before returning or using it, and propagate/throw a clear
error on validation failure so callers always receive validated types. Ensure
you reference the existing symbols ColumnInfo, TableInfo and the scan() output
when implementing these changes.
- Line 6: The field currently declared as type: string should be narrowed to a
discriminated literal union of the exact scanner kinds ('text' | 'integer' |
'number' | 'boolean' | 'datetime' | 'json' | 'blob' | 'unknown') so consumers
get compile-time exhaustiveness checks; update the declaration in scanner.ts
(the object/type that declares type) to that union and adjust any switch/case or
handlers that pattern-match on type (e.g., in functions that switch on the
scanner's type) to rely on the discriminant and add a never/default branch where
appropriate to surface missing cases at compile time.
In `@betterbase/packages/cli/test/context-generator.test.ts`:
- Around line 79-92: The test "handles empty schema file with empty tables"
currently only asserts context.tables; update the test to also assert that
context.routes is empty by adding an assertion like
expect(context.routes).toEqual({}) after creating the ContextGenerator and
assigning context from await new ContextGenerator().generate(root); this ensures
ContextGenerator.generate produces an empty routes object when src/routes is
empty.
In `@betterbase/packages/cli/test/route-scanner.test.ts`:
- Around line 37-40: Update the test in route-scanner.test.ts to assert the HTTP
method for each entry under routes['/users'] so failures are self-describing;
specifically, after confirming routes['/users'] exists and has length 2, add
assertions that routes['/users'][0].method is 'GET' and
routes['/users'][1].method is 'POST' (or vice versa if your expected order
differs) before asserting requiresAuth and inputSchema so the test will clearly
indicate which route entry is mismatched if traversal order changes.
In `@betterbase/README.md`:
- Around line 23-42: Add brief usage docs for the new CLI commands and realtime
support: document the commands "bb auth setup" and "bb generate crud" (one-line
synopsis and example invocation each) and note WebSocket realtime support and
where to find usage/activation details (e.g., how to enable realtime in
generated projects); if full CLI docs live in packages/cli/README.md, add a
cross-reference line pointing readers there and include links or paths and any
required flags/options for these commands; update templates/base README to
mention these features when relevant so new projects can discover and run them.
In `@betterbase/templates/base/package.json`:
- Line 15: The template's package.json pins zod at "^3.23.8"; update the
dependency entry for "zod" to a Zod v4 range (e.g. "^4.0.0" or a more specific
v4.x) in the package.json so scaffolded projects use Zod 4, then run install and
test the template build to catch any breaking changes in code referencing Zod
APIs (search for imports/usages of "zod" and update schema/validation code to v4
APIs if needed).
In `@betterbase/templates/base/src/lib/realtime.ts`:
- Around line 27-29: The RealtimeServer currently lets the private maps clients
and tableSubscribers grow unbounded; add configurable caps and enforce them when
new connections or subscriptions are created: introduce maxClients and
maxSubscriptionsPerClient (and optionally maxSubscribersPerTable) as
RealtimeServer config properties, check clients.size before accepting/adding a
ServerWebSocket<unknown> in whichever constructor/accept/handleConnection
routine and reject/close the socket with a clear error if cap is reached, and
when adding to tableSubscribers or the per-Client subscription set (Client),
verify the per-client and per-table caps and reject the subscribe request (or
evict oldest subscription) while logging the event; ensure the checks reference
RealtimeServer.clients, RealtimeServer.tableSubscribers,
ServerWebSocket<unknown>, and Client so reviewers can find the insertion points.
- Around line 159-170: matchesFilter currently uses strict === for value
comparison which fails for nested objects/arrays; update matchesFilter (in
realtime.ts) to use a deep equality check instead of === for comparing filter
values to payload values. Add a small helper function (e.g., deepEqual(a,b))
that handles primitives, arrays, plain objects (recursing into entries and
comparing lengths), and null/undefined, and call deepEqual(data[key], value)
inside Object.entries(filter).every(...). Ensure you keep the existing guards
for non-object payloads and empty filters and reference the matchesFilter
function and the new deepEqual helper when making changes.

Add "jsx" compiler option to the base config.
The "strict": true option is properly set in tsconfig.base.json and correctly inherited. However, since this config already includes .tsx files in the glob patterns (lines 12, 14), a "jsx" compiler option must be explicitly defined. Currently, neither the base config nor this file defines it. Add "jsx": "react" (or the appropriate JSX mode for your setup) to betterbase/tsconfig.base.json to properly handle TypeScript's JSX transformation.

--filter '*' with POSIX single-quotes breaks on Windows cmd.exe.
On Unix/macOS, the shell strips the single quotes and Turbo receives --filter * correctly. On Windows with cmd.exe (the default shell used by bun run on Windows), single quotes are not quoting characters — Turbo would receive --filter '*' as a literal argument including the quote characters, which would either match nothing or error.
If Windows developer support is a goal, use double-escaped double quotes or the cross-platform cross-env / Bun shell workaround:

Unhandled ZodError from .parse() will produce raw 500 errors.
Both /signup (Line 47) and /login (Line 69) use signupSchema.parse() / loginSchema.parse() which throw a ZodError on invalid input. Without a Hono error handler or try/catch, clients receive an unstructured 500 response instead of a 400 with validation details.
Use .safeParse() or wrap with error handling:

validateSession leaks passwordHash into the request context.
validateSession does db.select().from(users) (select all columns) and returns user[0] directly. This includes passwordHash, which then gets set on the Hono context via c.set('user', user). The AuthContext interface only types id, email, name — but the runtime object carries the hash. Any handler doing c.get('user') has access to the hash, and a careless c.json(c.get('user')) leaks it in a response.
Select only the needed columns:

Migration runs against hardcoded path, ignoring DB_PATH env var.
migrate.ts uses DEFAULT_DB_PATH (always 'local.db'), but db/index.ts uses env.DB_PATH which respects the DB_PATH environment variable. If a user sets DB_PATH=production.db, the app connects to production.db but migrations run against local.db.

Hono v4 upgradeWebSocket Bun createBunWebSocket websocket handler required
💡 Result:
In Hono v4 on Bun, you must provide two different “handlers”:
- Route upgrade handler (Hono):
upgradeWebSocket(() => ({ ...events }))must return a WS-event object (e.g.onMessage,onClose, etc.). (hono.dev) - Server-level WebSocket handler (Bun): Bun requires a
websockethandler object onBun.serve(...)(or exported aswebsocketin Hono’s Bun adapter export). If you don’t, Bun will error/hang because the server has no WebSocketHandler. (bun.sh)
Hono v4 recommended (no createBunWebSocket)
import { Hono } from 'hono'
import { upgradeWebSocket, websocket } from 'hono/bun'
const app = new Hono()
app.get('/ws', upgradeWebSocket(() => ({
onMessage(event, ws) {
ws.send(String(event.data))
},
})))
export default { fetch: app.fetch, websocket }Hono’s docs explicitly show Bun requires exporting { fetch, websocket }. (hono.dev)
If you’re using Bun.serve directly
import { Hono } from 'hono'
import { upgradeWebSocket, websocket } from 'hono/bun'
const app = new Hono()
app.get('/ws', upgradeWebSocket(() => ({ onMessage: (e, ws) => ws.send(e.data) })))
Bun.serve({ port: 3000, fetch: app.fetch, websocket })Bun’s docs: the websocket parameter is where the server’s WebSocketHandler lives. (bun.sh)
When to use createBunWebSocket()
Only if you specifically need the factory form (const { upgradeWebSocket, websocket } = createBunWebSocket()), but the same rule still applies: you must pass/export websocket for Bun. (github.com)

WebSocket setup is incomplete — Bun.serve is missing the required websocket handler.
In Hono v4 with Bun, upgradeWebSocket requires a corresponding websocket object passed to Bun.serve(). The pattern is:
import { upgradeWebSocket, websocket } from 'hono/bun';
app.get('/ws', upgradeWebSocket(() => ({ /* handlers */ })));
Bun.serve({
fetch: app.fetch,
websocket, // required
port: env.PORT,
development: env.NODE_ENV === 'development',
});Currently, the file imports upgradeWebSocket only (line 2) and never passes websocket to Bun.serve() (lines 27–31). Without this, WebSocket upgrade requests will fail at the Bun server level.

Add authentication to WebSocket connections and authorization for table subscriptions.
The /ws endpoint accepts connections without verifying identity, and handleConnection immediately registers any client. The subscribe method allows clients to subscribe to any table with no access control. Consider implementing token-based authentication during the WebSocket upgrade (via headers or Hono context) and validating that clients have permission to subscribe to specific tables before allowing the subscription in the subscribe method.

handleConnection currently accepts and registers any ServerWebSocket without
authentication and subscribe allows any table subscription; add token-based
authentication during the WebSocket upgrade (inspect headers or Hono context)
and validate the token before calling handleConnection so only authenticated
identities are stored in this.clients (attach a userId/claims field to the
stored client object). In the subscribe method, lookup the client's identity
from this.clients and perform an authorization check against the requested table
(e.g., call an authorize(userId, tableName) helper or validate claims/scopes),
and only add to client.subscriptions if authorization succeeds; if auth or
authorization fails, close the socket or send an error message. Ensure errors
are logged via realtimeLogger and avoid registering unauthenticated clients by
modifying the upgrade flow that creates ServerWebSocket to reject or terminate
connections without valid tokens.
