# Writing guides (/docs/guides/making-guides) How to write, validate, and file a Prisma ORM guide for the Prisma documentation. Location: Guides > Writing guides ## Introduction This page is for people writing guides in this section. It covers the required structure, the formatting conventions, the validation rule every guide must pass, and how a guide's Prisma ORM 7 twin is versioned. The short version: a guide is a walkthrough you ran end to end before publishing, written for Prisma ORM, with every command shown alongside the real output it produced. ## Prerequisites - A clear understanding of the topic you are writing about - Access to the Prisma documentation repository - Familiarity with Markdown and MDX - Node.js 24 or later and a PostgreSQL database to validate against (a local server or `npx create-db@latest`) ## The validation rule Every command, file, and code block in a published guide was run by its author against a live database before it landed. Outputs shown in the guide are pasted from that run, trimmed for noise. If a step could not be run (a platform account you do not have, a paid service), the guide says so in the step and does not show output for it. Two reference guides show the finished shape. Read them before writing: - [Hono](/guides/guides-3-frameworks-hono): a new project scaffolded with `create-prisma`, deployed to Prisma Compute. - [PostgreSQL, existing project](/guides/prisma-orm-2-prisma-orm-add-to-existing-project-postgresql): the `orm init` and `contract infer` path for an app that already exists. ## Guide structure ### Required frontmatter ```mdx --- title: '[Descriptive title]' description: '[One sentence: what the reader builds or accomplishes]' url: /guides/[category]/[slug] metaTitle: How to use Prisma ORM with [Topic] metaDescription: '[One sentence for search results]' --- ``` - `title`: a short, descriptive title in sentence case (for example "Docker", "Multiple databases", "GitHub Actions") - `description`: one sentence describing what the reader accomplishes - `url`: the page path under `content/docs` without the extension; the build derives the URL from the file path, and this field must match it - `metaTitle` and `metaDescription`: the title and description for search engines - `image`: a header image for social sharing, only if one exists at `/img/guides/` ### Required sections 1. **Introduction** (`## Introduction`): what the guide builds, in two or three sentences, followed by the `Using Prisma ORM 7?` note (see [Versioning](#versioning-the-prisma-orm-7-twin)). 2. **Prerequisites** (`## Prerequisites`): Node.js 24 or later, a database connection string or `npx create-db@latest`, and any accounts the guide needs. Keep it to what is truly necessary. 3. **Use with your agent** (`## Use with your agent`): an `` block with a numbered prompt a coding agent can follow to complete the guide. Reference the guide's own `.md` URL (`https://www.prisma.io/docs/guides/[category]/[slug].md`) so the agent can read it. 4. **Numbered steps** (`## 1. Scaffold the project`, `## 2. Initialize the database`, and so on): each step is one bounded action with its command, its real output in a `no-copy` block, and one or two sentences on what happened. 5. **Common gotchas** (`## Common gotchas`): the failures you hit while validating, with the verbatim error text and the fix. 6. **Prompt your coding agent** (`## Prompt your coding agent`): a pointer to `npx prisma@latest init` for the [Prisma ORM skills](/guides/tools-skills) and two or three follow-up prompts that map to the guide. 7. **Next steps** (`## Next steps`): links to the fundamentals and the related Prisma ORM pages. ## Writing style and voice - Write direct instructional prose: say what to do, show the command, show the output. - Use active voice and present tense, and address the reader as "you". - Keep sentences short. One idea per sentence. - Do not use em dashes anywhere, including code comments. Use a period, a comma, or a colon. - Explain a removed Prisma ORM 7 step in one sentence only where a reader coming from Prisma ORM 7 would look for it (for example, "There is no `prisma generate` step; the runtime reads the emitted contract."). - Do not describe Prisma ORM 8 as a preview or as not production ready, and do not mention release candidate numbers. Prisma ORM 8 is the current release; Prisma ORM 7 remains supported. ### Code examples - Every code block is complete and was run as shown. - Use `title=` on file blocks: ` ```ts title="src/prisma/db.ts" `. - Use ` ```npm ` for package manager commands (the UI converts them to pnpm, yarn, and bun). - Use ` ```bash ` for other shell commands and for `.env` files, so `# [!code ++]` and `# [!code --]` annotations render. - Use ` ```text no-copy ` and ` ```json no-copy ` for captured output. - Use ` ```prisma ` for contract files, ` ```typescript ` or ` ```ts ` for TypeScript, ` ```json ` for JSON. - Use `// [!code ++]`, `// [!code --]`, and `// [!code highlight]` to show changes inside a file. ### Formatting conventions - Backticks for file names (`contract.prisma`), directories (`src/prisma/`), commands, and code elements (`db.orm.public.User`). - Admonitions for asides: ```markdown :::note Important details to remember ::: :::warning A gotcha that breaks the flow if missed ::: :::tip A shortcut or best practice ::: ``` - Never skip heading levels. - Link Prisma ORM 8 pages with relative paths: `/orm/...`, `/cli/...`, `/prisma-orm/...`. Never link `/orm/v7/...` from a Prisma ORM 8 guide except in the `Using Prisma ORM 7?` note. ## Prisma ORM patterns ### Versions in commands Commands that run before the project has Prisma installed use the `@latest` tag, never a pinned version: #### bun ```bash bunx create-prisma@latest my-app --template hono --provider postgres --no-deploy bunx prisma@latest orm init --target postgres bunx --bun prisma@latest init bunx create-db@latest ``` #### pnpm ```bash pnpm dlx create-prisma@latest my-app --template hono --provider postgres --no-deploy pnpm dlx prisma@latest orm init --target postgres pnpm dlx prisma@latest init pnpm dlx create-db@latest ``` #### yarn ```bash yarn dlx create-prisma@latest my-app --template hono --provider postgres --no-deploy yarn dlx prisma@latest orm init --target postgres yarn dlx prisma@latest init yarn dlx create-db@latest ``` #### npm ```bash npx create-prisma@latest my-app --template hono --provider postgres --no-deploy npx prisma@latest orm init --target postgres npx prisma@latest init npx create-db@latest ``` Every other command is `npx prisma `, which runs the version the project has installed. In CI that is the version from the lockfile, and a reader never sees a guide behave differently from their own checkout. The docs' command tabs render `npx prisma` as `pnpm prisma` and `yarn prisma` for the same reason. Package installs happen inside `create-prisma` and `orm init`; show their output rather than hand-written `npm install` lines with version numbers. ### New project Scaffold with `create-prisma` and one of its templates (`minimal`, `hono`, `elysia`, `nest`, `next`, `svelte`, `astro`, `nuxt`, `tanstack-start`): #### bun ```bash bunx create-prisma@latest my-app --template next --provider postgres --no-deploy ``` #### pnpm ```bash pnpm dlx create-prisma@latest my-app --template next --provider postgres --no-deploy ``` #### yarn ```bash yarn dlx create-prisma@latest my-app --template next --provider postgres --no-deploy ``` #### npm ```bash npx create-prisma@latest my-app --template next --provider postgres --no-deploy ``` The template ships the contract in `src/prisma/contract.prisma`, the runtime in `src/prisma/db.ts`, and package scripts for `contract:emit`, `db:init`, `db:update`, `migration:plan`, and `migrate`. ### Existing project Add Prisma ORM to an app that already exists: #### bun ```bash bunx prisma@latest orm init --target postgres ``` #### pnpm ```bash pnpm dlx prisma@latest orm init --target postgres ``` #### yarn ```bash yarn dlx prisma@latest orm init --target postgres ``` #### npm ```bash npx prisma@latest orm init --target postgres ``` For a database that already has tables, follow with `npx prisma contract infer --output ./src/prisma/contract.prisma`, review the contract, then `contract emit` and `db sign`. Two things to check in the review: `orm init` keeps `"type": "commonjs"` if your `package.json` declares it and adds `"type": "module"` if there is no `"type"` field (a new project should use `"type": "module"`; an existing CommonJS app follows [In a CommonJS project](/guides/orm-orm-init#in-a-commonjs-project)), and `contract infer` writes `Timestamptz` for timestamp columns while the runtime on Node.js needs `TimestamptzString`. ### Runtime instantiation Show the scaffolded `src/prisma/db.ts` rather than writing a client by hand: ```ts title="src/prisma/db.ts" import "dotenv/config"; import postgres from "@prisma/orm-postgres/runtime"; import type { Contract } from "./contract.d"; import contractJson from "./contract.json" with { type: "json" }; export const db = postgres({ contractJson, url: process.env.DATABASE_URL!, }); ``` Queries name the PostgreSQL schema (`db.orm.public.User.select("id", "email").all()`). Close the client once on process shutdown with `await db.close()`, never per request; in a per-request environment such as Cloudflare Workers, create the client inside the handler instead (see [Cloudflare Workers](/guides/guides-3-deployment-cloudflare-workers)). ### Database lifecycle | Task | Command | | ------------------------------------------ | ----------------------------------------- | | First apply and sign | `npx prisma db init` | | Check the database matches the contract | `npx prisma db verify` | | Apply a contract change during development | `npx prisma db update` | | Plan a checked-in migration | `npx prisma migration plan --name ` | | Apply checked-in migrations | `npx prisma db migrate` | ### Environment variables Show `.env` files with ` ```bash title=".env" `: ```bash title=".env" DATABASE_URL="postgresql://user:password@localhost:5432/mydb" ``` The CLI loads `.env` through `prisma.config.ts`. Scaffolded `db.ts` files import `dotenv/config`; `create-prisma` templates read the environment variable only, so tell the reader to export it in the shell. ## Versioning the Prisma ORM 7 twin The unversioned tree under `guides/` is Prisma ORM 8. Prisma ORM 7 guides live under `guides/v7/` with the same subpath, and the sidebar version dropdown switches between them. When you port a Prisma ORM 7 guide: 1. Copy the Prisma ORM 7 file to `guides/v7/` and change only its `url:` to the `/guides/v7/...` path. Keep its Prisma ORM 7 pins. 2. Add the file to the matching `guides/v7//meta.json` and to the list on [/guides/v7](/guides/guides-v7). 3. Write the Prisma ORM 8 guide over the original path. 4. Add this note right after the introduction of the Prisma ORM 8 guide: ```markdown :::note[Using Prisma ORM 7?] Prisma ORM 8 is the current release. Prisma ORM 7 remains fully supported; the Prisma ORM 7 version of this guide is at [/guides/v7/[category]/[slug]](/guides/v7/[category]/[slug]). ::: ``` If a topic cannot be ported because Prisma ORM 8 does not support it yet (for example Cloudflare D1, or a third-party adapter that requires Prisma Client), move the page under `guides/v7/`, change its `url:` frontmatter to the `/guides/v7/...` path (or re-run `npx tsx scripts/add-url-frontmatter.ts` in `apps/docs`; a stale `url:` fails silently and no linter catches it), add its filename to the matching `guides/v7//meta.json` and its link to `guides/v7/index.mdx` (a redirect alone leaves it out of the Prisma ORM 7 navigation), and add a redirect from the old URL in the live region of `redirects()` in `apps/docs/next.config.mjs`, near the `/llms/next.txt` entry (`apps/docs/vercel.json` holds the legacy redirects and the entries `pnpm generate:rest-api-docs` writes, not new page moves). Then run `pnpm run audit:redirects:strict` in `apps/docs`: it checks that every `vercel.json` destination still resolves, so it catches the legacy redirects whose destination just moved; it does not read `next.config.mjs`. Do not leave a Prisma ORM 7 page at a Prisma ORM 8 URL without a version marker. ## Guide categories | Category | Directory | Description | Examples | | ------------------- | ------------------------------ | --------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Framework** | `guides/frameworks/` | Integrate Prisma ORM with frameworks | [Next.js](/guides/guides-3-frameworks-nextjs), [Hono](/guides/guides-3-frameworks-hono), [React Router](/guides/guides-3-frameworks-react-router-7) | | **Runtime** | `guides/runtimes/` | Run Prisma ORM on a runtime | [Bun](/guides/guides-3-runtimes-bun), [Deno](/guides/guides-3-runtimes-deno) | | **Deployment** | `guides/deployment/` | Deploy apps and set up monorepos | [Docker](/guides/guides-3-deployment-docker), [Cloudflare Workers](/guides/guides-3-deployment-cloudflare-workers), [Turborepo](/guides/guides-3-deployment-turborepo) | | **Integration** | `guides/integrations/` | Use Prisma ORM with platforms and tools | [GitHub Actions](/guides/guides-3-integrations-github-actions), [AI SDK](/guides/guides-3-integrations-ai-sdk) | | **Database** | `guides/database/` | Database patterns and migrations | [Multiple databases](/guides/guides-3-database-multiple-databases), [Expand-and-contract migrations](/guides/guides-3-database-data-migration), [Schema changes](/guides/guides-3-database-schema-changes) | | **Authentication** | `guides/authentication/` | Authentication patterns | [Clerk with Next.js](/guides/guides-3-authentication-clerk-nextjs) | | **Prisma Postgres** | `guides/postgres/` | Prisma Postgres features | [Vercel](/guides/guides-3-postgres-vercel), [Netlify](/guides/guides-3-postgres-netlify), [Viewing data](/guides/guides-3-postgres-viewing-data) | | **Migration** | `guides/switch-to-prisma-orm/` | Switch from other ORMs | [From Drizzle](/guides/guides-3-switch-to-prisma-orm-from-drizzle), [From Mongoose](/guides/guides-3-switch-to-prisma-orm-from-mongoose) | | **Upgrade** | `guides/upgrade-prisma-orm/` | Move between Prisma versions | [Prisma ORM 7 to 8 on PostgreSQL](/guides/upgrade-prisma-orm-postgresql) | ## Guide template Copy this template for a new guide that adds Prisma ORM to an existing framework project.

To add a guide to the navigation, update the category's `meta.json`: ```json title="apps/docs/content/docs/guides/frameworks/meta.json" { "title": "Frameworks", "defaultOpen": true, "pages": [ "nextjs", "astro", "nuxt", "your-new-guide" // [!code ++] ] } ``` The page name is the `.mdx` filename without the extension. The top-level `guides/meta.json` lists the categories, and `guides/v7/meta.json` plus `guides/v7//meta.json` do the same for the Prisma ORM 7 tree. ## Next steps - Read the [Hono](/guides/guides-3-frameworks-hono) guide and match its shape. - Validate your guide end to end, then open a pull request with the sandbox commands you ran in the description. ## Related pages - [`Guides`](/guides/guides-v7): A collection of guides for various tasks and workflows ## Related pages - [Authentication & Tools](./authentication-tools-index.md) - [Build](./build-index.md) - [Changelog](../changelog.md) - [Concepts](./concepts-index.md) - [Console commands](./console-commands-index.md) - [Contract Authoring](./contract-authoring-index.md) - [Core Concepts](./core-concepts-index.md) - [Data Modeling](./data-modeling-index.md) - [Database](./database-index.md) - [DB commands](./db-commands-index.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
