docs(orm): document every migration operation and contract construct that ships, verified by running each one - #8306
Conversation
A new reference page, /orm/reference/migration-api, lists everything a migration.ts can call: the Migration class and the migration-file CLI, the four operation classes and the two checks, every PostgreSQL operation with the SQL it runs, the column and constraint helpers, dataTransform, rawSql, and the MongoDB operations. The site previously showed six of the thirty-odd methods. Every PostgreSQL operation was run against Postgres 17 with @prisma/orm-postgres 8.0.0-rc.11 and prisma 8.0.0-rc.15: 34 operations in one migration, plus a rawSql column rename verified by db verify. The SQL in the Runs columns is what those runs produced. Two findings from the run are recorded on the page: setDefault's defaultSql must include the DEFAULT keyword, and createTable's ifNotExists option has no effect, so it is not listed. Six reader-review rounds. Editing a migration links to the page.

The two authoring pages now cover what ships but was undocumented. PSL: the @default generator list (uuid(7), cuid(2), ulid(), nanoid(n), dbgenerated), scalar lists and @nocheck, @@index with expression:, where:, unique:, type:, and name: versus map:, @@check, @@control with the four policies, namespace blocks, row-level security (@@rls, the policy_* and role blocks), @relation("Name") with onDelete/onUpdate values, the inline extension type form, the big-integer types, and MongoDB's @@index, @@unique, and @@textIndex arguments. TypeScript: the naming, foreignKeyDefaults, defaultControlPolicy, and namespaces options, the config output option, .many() and .noCheck(), index expression/where/type forms, checks and control on .sql(...), namespaces on a model, row-level security through entities, and the MongoDB builder's index options, collectionOptions, valueObject, field.vector(), and discriminator/base polymorphism. Every construct was emitted with @prisma/orm-postgres 8.0.0-rc.11 and @prisma/orm-mongo 8.0.0-rc.11 and the lowered contract.json inspected. One reader-review round on each page.

…ract emit (C16) contract emit gains a "Run it automatically" section: the prismaVitePlugin export of @prisma/orm-postgres and @prisma/orm-mongo, its two options, what the dev server prints, and the prebuild script for every other bundler and for builds. The artifact page's version control section and the three Vite-based framework guides (React Router, SolidStart, TanStack Start) point at it. Verified with Vite 7.3.6 and @prisma/orm-postgres 8.0.0-rc.11: the plugin emitted on server start and again after a contract edit.

- Line 246: Update the UnboundedInt table row to contain only its three intended
cells, then move the Prisma ORM 8 reference paragraph immediately below the
table as normal Markdown text.
In `@apps/docs/content/docs/orm/contract-authoring/the-contract-artifact.mdx`:
- Line 139: Update the Vite plugin descriptions to state that emission occurs
during development startup and when the contract source or prisma.config.ts
changes, rather than “on every save.” Apply this wording at
apps/docs/content/docs/orm/contract-authoring/the-contract-artifact.mdx:139-139,
apps/docs/content/docs/guides/frameworks/react-router-7.mdx:561-561,
apps/docs/content/docs/guides/frameworks/solid-start.mdx:408-408, and
apps/docs/content/docs/guides/frameworks/tanstack-start.mdx:118-118; no other
behavior or documentation needs changing.
In `@apps/docs/content/docs/orm/contract-authoring/typescript-schema-builder.mdx`:
- Line 284: Update the expression-index documentation to state that an
expression index requires the name option, while retaining map as the exact-name
option for non-expression indexes. Replace the wording around “An expression
index needs one of the two” accordingly, without changing the surrounding
constraints.index option guidance.
In `@apps/docs/content/docs/orm/reference/migration-api.mdx`:
- Around line 469-499: Add the missing definitions referenced by the migration
example: import MongoQueryPlan and RawUpdateManyCommand from their established
modules, and define existingProductsWithoutStatus with the same
storageHash-aware AggregateCommand query described in the text. Alternatively,
clearly label both snippets as incomplete excerpts and link to the complete
implementation, ensuring copied code is not presented as self-contained.
- Around line 290-303: Update the pgcrypto project-migration recommendation in
apps/docs/content/docs/orm/migrations/editing-a-migration.mdx at line 244 to use
the plain createExtension('pgcrypto') operation instead of
this.installExtension; the reference guidance in
apps/docs/content/docs/orm/reference/migration-api.mdx lines 290-303 already
reflects the correct behavior and requires no direct change.

The big-integer table no longer swallows the paragraph after it. The Vite plugin pages say when it emits (contract or config changes while the dev server runs) instead of "on every save". Editing a migration points the pgcrypto example at createExtension, matching the reference. The MongoDB data-transform excerpt carries its imports and both helper functions, so it can be copied whole. The suggestion that an expression index refuses `map` was checked and is wrong: both PSL and the TypeScript builder emit an expression index with `map` on rc.11, so that wording stays.

…dex on the PSL page The "named arguments are" list for @@index and @@unique on MongoDB left out four that @prisma/orm-mongo 8.0.0-rc.11 accepts: default_language and languageOverride for a type: "text" index, and include or exclude for a wildcard index. The wildcard() field element, which those two narrow, was not on the page either. Adds them, with the rules the lowering enforces: one wildcard() per index, not on @@unique, and not with expireAfterSeconds or a type: such as "hashed".

At a glance
A reader who wants a partial index on PostgreSQL could write this in
contract.prismatoday, but no page told them:And a reader editing a
migration.tscould call any of these, but the site showed six of them:After this PR, every migration operation has a row with the SQL it produces, and every contract construct that rc.11 accepts has a section on the PSL or TypeScript page.
The decision
Document what ships, and only what we ran. Each construct on these pages was emitted or applied against a real database with
@prisma/orm-postgresand@prisma/orm-mongo8.0.0-rc.11, and the text describes what came out, not what a README says. Where a README and the tool disagree, the page follows the tool and the PR notes the README (see the end).This is three additions to the docs, one commit each, and no restructuring: a new reference page for migrations, new sections on the two contract-authoring pages, and one new section on the
contract emitpage.1. A Migration API reference page
/orm/reference/migration-apiis new. The migrations section already had a good tutorial for editing a planned migration, but a reader who needed an operation the planner had not written for them, such as a foreign key across schemas or a row-level security policy, had nothing to look up. TheMigrationbase class has about thirty methods; the site showed six.The page covers the shape of
migration.tsand the migration-file CLI (--dry-run,--config), the four operation classes and the two checks around every operation, each PostgreSQL method grouped by what it changes (tables, columns, constraints, indexes, native enums, row-level security, extensions), the column and constraint helpers,dataTransformwith the lines that build its query builder,rawSqlwith a worked column rename, and the MongoDB operations. Editing a migration links to it.Verification: one migration with 34 operations, one of every method, recompiled with
node migration.ts, passedmigration check, and applied to Postgres 17 withdb migrate. The SQL in the Runs columns is what those runs produced. A second migration replaced the planner's drop-and-add with arawSqlrename and passeddb verify. Six reader-review rounds.Two things the run turned up are stated on the page rather than hidden:
setDefaultrunsSETfollowed by your string verbatim, sodefaultSqlmust include theDEFAULTkeyword; andcreateTableaccepts anifNotExistsoption that has no effect, so it is not listed.2. The PSL and TypeScript contract pages
Both pages had just been through the plain-language pass, so these are additions, not a rewrite. What was missing, on both pages where both forms support it:
expression:,where:,unique:,type:, and the difference betweenname:(Prisma ORM names the object, with a hash) andmap:(you name it, for objects that already exist)@noCheckto waive the ones Prisma ORM generatesdb verifyand to migrations@defaultgenerator list, the big-integer types, the inline extension type form@@index,@@unique, and@@textIndexarguments in PSL; index options,collectionOptions, value objects,field.vector(), and polymorphism in the buildernaming,foreignKeyDefaults,defaultControlPolicy, andnamespacesoptions and the configoutputoption in TypeScriptVerification: one PSL contract and one TypeScript contract per database using every construct, emitted with
contract emit, and the loweredcontract.jsoninspected. One reader round per page.3. Build integration
contract emitgains a "Run it automatically" section: the Vite plugin (prismaVitePluginfrom@prisma/orm-postgres/vite-plugin-contract-emit, or the Mongo package), its two options, what the dev server prints, and theprebuildscript for every other bundler. The artifact page and the three Vite-based framework guides point at it. Verified with Vite 7.3.6: the plugin emitted on server start and again after a contract edit.What to review
The three pages are long; the fastest read is the migration reference page's tables and the two control-policy tables. If you know a construct that rc.11 accepts and these pages do not show, that is the kind of gap this PR is for.
