πŸ“ Walkthrough

Walkthrough

This PR introduces a comprehensive production-ready TypeScript HTTP client for the SolFoundry SDK. It adds a new SolFoundryClient main entry point that orchestrates an AuthManager (for credential/token management) and HttpClient (for centralized request execution with retry, rate-limiting, and error handling). The SDK exposes three resource API classesβ€”BountiesApi, SubmissionsApi, and UsersApiβ€”each extending a shared BaseApi abstract class. Supporting infrastructure includes a RateLimiter for client-side request pacing, a SolFoundryError custom error class, and comprehensive TypeScript type definitions for bounties, submissions, users, client configuration, and common utilities. The README is updated to demonstrate the new client usage patterns, and package.json metadata is refreshed. The old SolFoundry facade and program-related exports are removed.

Inline comments:
In `@sdk/package.json`:
- Around line 32-34: The "clean" npm script uses a POSIX-only command ("rm -rf")
which breaks on Windows and thus makes "prepublishOnly" non-portable; replace
the platform-specific command by adding a cross-platform cleaner (e.g., add
rimraf as a devDependency or use del-cli) and update the "clean" script to call
that tool (so "clean" and consequently "prepublishOnly" work on
Windows/macOS/Linux), reference the "clean" and "prepublishOnly" script names in
package.json when making the change.

In `@sdk/README.md`:
- Around line 172-174: Replace the absolute local filesystem links in README.md
that point to /Users/akii/... with repository-relative or upstream URLs so
consumers can follow them; specifically update the three entries referring to
docs/API.md, src/client/SolFoundryClient.ts (SolFoundryClient.ts) and
src/types/index.ts (exported types) to use relative paths like docs/API.md,
src/client/SolFoundryClient.ts, src/types/index.ts or canonical GitHub URLs, and
remove any local path remnants to avoid leaking developer environment details.

In `@sdk/src/auth/AuthManager.ts`:
- Around line 68-72: The clear() method currently clears apiKey along with
accessToken and refreshToken, which unintentionally disables API-key
authentication; modify the code so clear() only removes session tokens
(accessToken and refreshToken) and do not touch apiKey, or introduce a separate
clearSession() that clears only accessToken and refreshToken while leaving
apiKey intact; if needed add a new clearAllAuth() (or explicit method) to clear
apiKey as well so callers can opt-in to removing API-key authentication.

In `@sdk/src/errors/SolFoundryError.ts`:
- Line 37: The SolFoundryError constructor currently uses a truthy check that
drops explicitly provided falsy causes; change the call to super in
SolFoundryError so it preserves explicit falsy values by checking presence
rather than truthiness (e.g., use Object.prototype.hasOwnProperty.call(options,
'cause') or the 'cause' in options test) and pass { cause: options.cause } when
the cause key is present, otherwise pass undefined to super(message, ...).

In `@sdk/src/types/client.ts`:
- Around line 98-123: RequestOptions.query currently allows null but the
query-building code only filters undefined, causing "null" to appear in URLs;
update the check in the client code that constructs the query string (the block
that currently uses if (value !== undefined)) to exclude both undefined and null
(e.g., use if (value !== undefined && value !== null) or if (value != null)) so
null-valued query params are omitted when serializing RequestOptions.query.
- Around line 6-19: Update the JSDoc for the SolFoundryAuthConfig interface to
document auth precedence and combination: state that getAccessToken (the
getAccessToken callback) takes precedence over accessToken (used as a fallback
when the callback returns undefined), and clarify that apiKey is always sent as
the X-API-Key header in addition to any bearer token (i.e., apiKey is not
mutually exclusive with bearer auth). Reference the symbols
SolFoundryAuthConfig, getAccessToken, accessToken, and apiKey so readers can
locate the behavior in AuthManager where token resolution uses (await
this.getAccessToken?.()) ?? this.accessToken.

In `@sdk/src/types/submissions.ts`:
- Around line 63-80: CreateSubmissionInput currently allows empty submissions
because both artifactUrl and content are optional; update the
CreateSubmissionInput type to enforce that at least one of artifactUrl or
content is provided (e.g., replace the single interface with a union that
requires either { artifactUrl: string; content?: string } or { content: string;
artifactUrl?: string } or otherwise make one field required), or if you prefer
not to change the type, add a clear comment on CreateSubmissionInput stating
that server-side validation requires at least one of artifactUrl or content and
ensure the API docs reflect that constraint; reference the CreateSubmissionInput
interface and the artifactUrl and content fields when making the change.

🧹 Nitpick | πŸ”΅ Trivial

Build pipeline scripts are not cross-platform.

Line 32 relies on rm -rf, which is not portable to default Windows environments; this can break prepublishOnly on contributor/release machines outside POSIX shells.

Session clear logic also drops API-key auth state.

Falsy cause values are silently discarded.

Line 37 uses a truthy check before passing cause, so explicitly provided falsy causes are not preserved on the error instance. This can lose intended debugging context in edge cases.

Document auth configuration precedence in SolFoundryAuthConfig JSDoc.

The SolFoundryAuthConfig interface allows specifying accessToken, apiKey, and getAccessToken simultaneously, but the JSDoc does not document the resolution order or behavior when multiple auth methods are provided. The implementation in sdk/src/auth/AuthManager.ts (line 23) shows that getAccessToken callback takes precedence over accessToken when both are set (const token = (await this.getAccessToken?.()) ?? this.accessToken), and apiKey is independently added to all requests regardless of bearer token configuration. Update the JSDoc to clarify: (1) the precedence order between getAccessToken and accessToken, and (2) that apiKey is sent alongside bearer token authentication when both are provided.

RequestOptions.query allows null values that are not filtered, creating malformed URLs.

The RequestOptions.query type at line 102 permits null values, but the filtering logic in sdk/src/client.ts:158 only checks if (value !== undefined). This allows null values to pass through and be stringified as the literal string "null" when constructing the query string, producing malformed URLs like ?param=null instead of omitting the parameter. The condition must be updated to filter both undefined and null values.

CreateSubmissionInput allows empty submissions.

Both artifactUrl (line 71) and content (line 75) are optional. This permits creating a submission with no actual content, which may be unintentional. Consider:

  1. Making at least one required, or
  2. Documenting that the API validates this constraint server-side, or
  3. Using a discriminated union to enforce at least one is present
