docs(upgrade): stop recommending "module": "nodenext" by default - #8319
Conversation
The Prisma ORM 7 to 8 upgrade guide told readers to use "module": "nodenext", which under "type": "module" makes TypeScript require a .js extension on every relative import. Prisma 8 only needs a module setting that accepts JSON import attributes. Section 2.6 now starts from the reader's current setup and gives the setting for each kind of project, following docs/reference/typescript-module-settings.md in prisma/orm. The runtime reference no longer states preserve and bundler as requirements.

those using nodenext, to the CommonJS guidance that omits the attribute.

The prerequisites, section 2.6, and the runtime reference gave TypeScript 5.3 (5.4 for "module": "preserve") as the requirement. Those are the versions that accept the JSON import attribute, but @prisma/orm-postgres declares a typescript >=5.9 peer dependency, and release-status.mdx and the MongoDB upgrade guide already say 5.9 or newer. State 5.9 in the prerequisites and the runtime reference, and drop the 5.3 and 5.4 qualifiers, which a reader on 5.9 already satisfies.

Six reader-review rounds on section 2.6 and the runtime reference paragraph. The cases are now keyed on how the app runs rather than on the current tsconfig value, so a bundled app without "type": "module" no longer lands in the CommonJS case. Each case names its moduleResolution, the CommonJS case shows the attribute-free import, and the check line says what it does and does not test.

…ds ./contract.js The runtime reference now lists nodenext, node18, and node20 as accepted module settings but still told every reader to write ./contract.d with no extension. In a file TypeScript treats as an ES module under those settings that specifier fails with TS2307; ./contract.js resolves there and under preserve or esnext with bundler. Name both forms and when each applies.

… rule The nodenext ES-module case told readers that every relative import must end in .js. Step 3.1 imports ../generated/prisma8/contract.json, which keeps its .json extension and its import attribute. Say the rule covers imports of .ts and .d.ts files and name the JSON import as the exception.

Tested every tsconfig case against @prisma/orm-postgres 8.0.0-rc.12 with TypeScript 5.9.3 and 7.0.2 on Node 26. Node's type stripping runs the scaffolded db.ts when relative imports carry .ts extensions and allowImportingTsExtensions is on, under both the bundler and the nodenext pair. A CommonJS file that keeps the with part fails with TS2856, not TS2823, so the check line names both.

Why
The Prisma ORM 7 to 8 upgrade guide for PostgreSQL told readers to use
"module": "nodenext". Under"type": "module"that makes TypeScript require a.jsextension on every relative import, and a reader who followed the guide had to rewrite all their imports. Prisma 8 does not neednodenext. It needs anymodulesetting that accepts JSON import attributes,resolveJsonModule, and the emittedcontract.d.tsininclude.Source of truth for every claim: typescript-module-settings.md in prisma/orm.
What changed
modulesetting (keep it); CommonJS staying CommonJS (nodenext, no"type": "module", attribute-free JSON import); run throughtsx,vite,next,esbuild, or another bundler (preserve+bundler, TypeScript 5.4); compiled withtscand run with plainnodeas ES modules (nodenext,.json every relative import, linked to the TypeScript module reference). The tsconfig excerpt no longer shows"module": "nodenext".preserve) and a compatiblemodulesetting, and no longer namenodenextas the example.preserveandbundleras requirements of the JSON import. It names them as whatprisma orm initwrites and links to the guide for the other cases.Searched
