…projects The prisma-client generator treated any tsconfig `module` value other than "commonjs" as ESM, including "nodenext"/"node16". Under those modes, TypeScript decides CJS vs ESM per-file based on the nearest package.json's "type" field, so a CJS project (no "type": "module") using nodenext would get an ESM-only client containing `import.meta.url`, which crashes at runtime once required from CommonJS. Now, for nodenext/node16, we look up the nearest package.json to the output directory and only infer "esm" when its "type" field is "module", defaulting to "cjs" otherwise (including when no package.json is found). Fixes prisma#29710

…projects (prisma#29712) ## Summary - The `prisma-client` generator inferred `moduleFormat` by checking whether `tsconfig.json`'s `compilerOptions.module` was literally `"commonjs"`, treating anything else (including `"nodenext"`/`"node16"`) as ESM. - Under `nodenext`/`node16`, TypeScript actually decides CJS vs ESM per file based on the nearest `package.json`'s `"type"` field, not the `module` setting alone. A CJS project (no `"type": "module"`) using `nodenext` therefore got an ESM-only client containing `import.meta.url`, which crashes at runtime once `require()`'d (`ReferenceError: exports is not defined in ES module scope`). - This PR makes `inferModuleFormat` mirror `tsc`'s own resolution for `nodenext`/`node16`: look up the nearest `package.json` to the generator's output directory and infer `"esm"` only when its `"type"` field is `"module"`, defaulting to `"cjs"` otherwise (including when no `package.json` is found). Other `module` settings (`commonjs`, `esnext`, etc.) are unaffected. Closes prisma#29710 ## Test plan - [x] Added `packages/client-generator-ts/tests/module-format.test.ts` — unit tests covering `commonjs`/`esnext` unconditional behavior, `node16`/`nodenext` (with casing variants) against `package.json` with `type: module`, `type: commonjs`, no `type` field, and no `package.json` found, plus the pre-existing extension-based fallback. - [x] `pnpm run build` in `packages/client-generator-ts` — clean, no type errors. - [x] Full package test suite (50 tests, including `generator.test.ts`) passes with no regressions. - [x] Manually reproduced the exact bug report: CJS project (no `"type"` field) + `tsconfig.json` with `module: nodenext` + no explicit `moduleFormat` → generated client now has no `import.meta.url`, compiles cleanly with `tsc`, and runs under `node` without crashing. - [x] Verified no regression for genuine ESM projects: `"type": "module"` + `module: nodenext` → generated client still correctly gets `import.meta.url` and runs under Node's ESM loader.

Once 7.10.0 is released, a side-by-side installation can use: ```sh npm install --save-dev prisma@8 @prisma/prisma7@7.10.0 npm install @prisma/client@7.10.0 ``` Use `prisma` for the directly installed Prisma 8 CLI and `prisma7` for Prisma 7: ```sh npx prisma --version npx prisma7 --version npx prisma7 generate npx prisma7 migrate dev npx prisma7 db push ``` Prisma 7 now prefers version-specific configuration files, allowing its configuration to coexist with Prisma 8's `prisma.config.*` files: ```ts // prisma7.config.ts import { defineConfig } from '@prisma/prisma7/config' export default defineConfig({ schema: 'prisma/schema.prisma', migrations: { path: 'prisma/migrations', }, }) ``` Without an explicit `--config` option, Prisma 7 searches for: 1. Root-level `prisma7.config.*` files. 2. `.config/prisma7.*` files. 3. Existing `prisma.config.*` files as a backwards-compatible fallback. The supported extensions are `.js`, `.ts`, `.mjs`, `.cjs`, `.mts`, and `.cts`. An explicit config path always takes precedence: ```sh npx prisma7 generate --config ./custom/prisma7.config.ts ``` New projects initialized by the Prisma 7 CLI use `prisma7.config.ts`. Existing projects containing only `prisma.config.*` continue to work without migration or additional warnings. If a `prisma7.config.*` file exists but cannot be loaded, Prisma reports the error rather than silently falling back to another configuration. The `prisma7` identity is carried through CLI help, version output, shell completion, initialization, migration, database, and generation guidance. Stable Prisma concepts such as `schema.prisma`, Prisma Migrate, `@prisma/client`, and `PRISMA_*` environment variables remain unchanged. Together, the separate executable and configuration namespace make it possible to operate Prisma 7 and Prisma 8 side by side without command or config-file collisions. [#​29949](prisma/orm#29949), [#​29969](prisma/orm#29969), [#​29994](prisma/orm#29994), [#​30000](prisma/orm#30000), [#​30002](prisma/orm#30002), [#​30020](prisma/orm#30020) ##### Prisma Studio security hardening Prisma Studio's local HTTP server now: - Binds explicitly to `127.0.0.1` instead of all network interfaces. - Rejects browser requests from origins other than the active `localhost` or `127.0.0.1` Studio URL. - No longer returns wildcard CORS headers. - Applies the same protections across Node.js, Bun, and Deno. This prevents network clients or malicious websites from accessing Studio's database endpoints while Studio is running. [#​29890](prisma/orm#29890) ##### Prisma Client - Fixed `P2002` errors from nested writes so `meta.modelName` identifies the model where the unique constraint violation occurred, including models using `@@map` and `@@schema`. [#​29628](prisma/orm#29628) - Fixed automatically batched `findUniqueOrThrow()` calls so every missing record rejects with `P2025`; later misses no longer resolve to `undefined`. [#​29654](prisma/orm#29654) - Parameter-chunked statements are now executed atomically in a transaction and rolled back if a later chunk fails. [#​29771](prisma/orm#29771) - Improved interactive transaction cleanup during `$disconnect()`, including transactions whose driver-level startup is still in progress. [#​28768](prisma/orm#28768) - Prevented transaction cleanup failures after a timeout or backend termination from becoming unhandled promise rejections. [#​29611](prisma/orm#29611) - Fixed fluent relation queries when relation fields are literally named `select` or `include`. [#​29683](prisma/orm#29683) - Fixed handling of `Date` and `Uint8Array` values created in other JavaScript realms, such as iframes, jsdom, and Node.js `vm` contexts. [#​29177](prisma/orm#29177) - Invalid `Date` values passed to `$queryRaw` or `$executeRaw` now throw `PrismaClientValidationError` instead of a generic error. [#​29718](prisma/orm#29718) - Fixed `moduleFormat` inference for the `prisma-client` generator in TypeScript projects using `module: "node16"` or `"nodenext"`. Generated output now follows the nearest `package.json` `type`, defaulting to CommonJS when absent. [#​29712](prisma/orm#29712) - Deserialized `Bytes` values now own standalone `ArrayBuffer`s rather than exposing unrelated contents from Node.js's shared `Buffer` pool. This applies to both regular and raw query results. [#​29701](prisma/orm#29701) - Fixed an incorrect logging context in the remote executor, including Accelerate-backed query execution. [#​28892](prisma/orm#28892) ##### Client extensions and observability - Result-extension `compute` callbacks now receive the current model name as a typed second argument: ```ts compute(data, modelName) { // ... } ``` The model name is also preserved when multiple extensions compose the same computed field. [#​29782](prisma/orm#29782) - Improved OpenTelemetry context for remotely executed queries: - `$on('query')` callbacks run within the matching `db_query` span. - Events from one operation share the same trace. - Error events are recorded as span exceptions. - Log events continue to be emitted when tracing is disabled or their reported span is unavailable. [#​28892](prisma/orm#28892) ##### Driver adapters ##### MariaDB - `@prisma/adapter-mariadb` now accepts an existing `mariadb` pool. External pools remain caller-owned unless `disposeExternalPool: true` is supplied. [#​27992](prisma/orm#27992) - Fixed pooled connection leaks during commit, rollback, and failed transaction startup. Connections are now returned with `release()` and transaction-specific listeners are removed before reuse. [#​29612](prisma/orm#29612) - Added support for bracketed IPv6 addresses in both `mysql://` and `mariadb://` connection strings. [#​29026](prisma/orm#29026) - Prevented malformed connection strings from exposing embedded passwords in retained debug output and diagnostic reports. [#​27992](prisma/orm#27992) ##### PostgreSQL, Neon, and Prisma Postgres Serverless - PostgreSQL deadlocks using SQLSTATE `40P01` are now reported as `P2034` transaction write conflicts. [#​29717](prisma/orm#29717) - PostgreSQL `RESTRICT` violations using SQLSTATE `23001` are now reported as `P2003`, preserving an available field or constraint name. [#​29554](prisma/orm#29554) - `@prisma/adapter-pg` now preserves database constraint names when reporting unique constraint violations through `P2002`. [#​29587](prisma/orm#29587) - Prisma Postgres Serverless now prefers the named constraint for `P2002`, falling back to parsed field names when no constraint name is available. [#​29801](prisma/orm#29801) - Fixed Neon HTTP adapter serialization for typed parameters such as `Bytes` and `DateTime`. [#​29747](prisma/orm#29747) ##### SQLite - `@prisma/adapter-better-sqlite3` now converts previously unhandled SQLite result codes into typed database errors instead of exposing raw driver errors. - The complete `SQLITE_BUSY` family is now mapped to socket timeout errors, with numeric extended result codes preserved where available. [#​29794](prisma/orm#29794) ##### CLI and Migrate - `prisma generate` can now offer to install Prisma's agent skills. The opt-in prompt: - Is shown at most once per machine. - Is skipped in CI, containers, Git hooks, npm lifecycle scripts, and watch mode. - Is skipped when `--no-hints` is used or Prisma skills are already installed. - Times out after 30 seconds. - Never causes generation to fail if installation is unsuccessful. [#​29690](prisma/orm#29690) - A globally installed CLI now warns during `prisma generate` when its version differs from the project's local `prisma` or `@prisma/client`, and recommends running the local CLI. The check is best-effort and does not fail generation. [#​29593](prisma/orm#29593) - `prisma version` and `prisma version --json` now include the resolved Prisma CLI package path, making global-versus-local installation issues easier to diagnose. [#​29573](prisma/orm#29573) - Empty or generator-only schema files now report `Schema must contain a datasource block` from `db pull`, `db push`, and `migrate dev`, rather than reaching the schema engine and potentially producing inconsistent errors. [#​29657](prisma/orm#29657) - CLI commands now tolerate corrupt, unreadable, or unwritable command-state files. Invalid state is reinitialized, writes are atomic, and persistence failures fall back to in-memory state. [#​29609](prisma/orm#29609) - Studio now recognizes semicolon-delimited `sqlserver://` connection strings before reporting the existing explicit message that SQL Server is not supported by Studio. [#​29623](prisma/orm#29623) - The AI-agent safety checkpoint now also covers interactive `prisma db push` confirmations involving data-loss warnings, rather than only invocations using `--accept-data-loss`. [#​29793](prisma/orm#29793) ##### Performance and reliability - Optimized query-plan execution by eagerly evaluating plans with one unconditional database operation and synchronously interpreting the remaining pure plan. Cached plans remain immutable. [#​29004](prisma/orm#29004) - Prevented call-stack overflows when rendering very large parameter lists or combining chunked results containing hundreds of thousands of rows. [#​29751](prisma/orm#29751) - Reduced ordinary query setup overhead by constructing fluent-relation field maps lazily and in linear time. Non-fluent queries no longer build this map. [#​29752](prisma/orm#29752) ##### Dependencies - Updated the transitive `fast-uri` dependency to a patched release addressing production audit advisories affecting versions through `3.1.3`.
