# Prisma Compute Framework Readiness

Use this reference when deciding whether and how an app can deploy to Prisma Compute.

## CLI-First Model

Treat `@prisma/cli app deploy` as the deployment surface. Treat `create-prisma` as a new-project scaffold that can generate useful defaults and, for some templates, a `compute:deploy` script.

Compute deploy supports these framework keys:

```text
nextjs
nuxt
astro
hono
nestjs
tanstack-start
custom
bun
```

Auto-detection:

- Next.js: `next.config.*` or `next` dependency
- Nuxt: `nuxt.config.*` or `nuxt` dependency
- Astro: `astro.config.*` or `astro` dependency
- Hono: `hono` dependency
- NestJS: `nest-cli.json` or `@nestjs/core` dependency
- TanStack Start: `@tanstack/react-start` or `@tanstack/solid-start`
- Custom artifact: explicit `framework: "custom"` plus `build.outputDirectory` and `build.entrypoint` in `prisma.compute.ts`
- Bun: explicit `--entry <path>` or `--framework bun`

If detection is ambiguous, set `framework` in `prisma.compute.ts` or pass a supported `--framework` value. If the app is a source-level plain server, use `framework: "bun"` plus `entry`, or pass `--framework bun --entry <path>`, after verifying the server entrypoint. If the app already produces a runnable Node artifact, use `framework: "custom"` with `build.outputDirectory` and `build.entrypoint`.

## CLI Matrix

| App shape | Deploy command shape | Auto-detected | Required output/entry | Notes |
|-----------|----------------------|---------------|-----------------------|-------|
| Next.js | `--framework nextjs` | Yes | standalone `server.js` output | Requires `output: "standalone"` |
| Nuxt | `--framework nuxt` | Yes | `.output/server/index.mjs` | Framework strategy supplies build defaults; a config `build` block is optional |
| Astro | `--framework astro` | Yes | standalone Node server artifact | Framework strategy supplies build defaults; a config `build` block is optional |
| Hono | `--framework hono` | Yes | Bun entry from `main`, `module`, `--entry`, or `src/index.ts` | Usually fixed port `8080` in generated config/scripts |
| NestJS | `--framework nestjs` | Yes | NestJS server artifact | Omit host or bind to `0.0.0.0`; a config `build` block is optional |
| TanStack Start | `--framework tanstack-start` | Yes | `.output/server/index.mjs` | Requires Nitro node output |
| Custom artifact | config-backed `framework: "custom"` | No | configured `build.outputDirectory` and `build.entrypoint` | Use for prebuilt/custom-built Node artifacts |
| Bun / plain server | `--framework bun --entry <path>` | With explicit entry | server entrypoint | Use for Elysia and custom HTTP servers |
| Elysia | `--framework bun --entry src/index.ts` | No dedicated deploy key | Bun entrypoint | Preserve port/host handling |
| SvelteKit | No deploy framework key | No | Node adapter/prebuilt artifact | Do not deploy `vite preview` |
| Turborepo | Deploy concrete app targets | No | app-specific entry/output | Prefer `prisma.compute.ts` with `apps` |

`app build --build-type` uses the framework build type. Build types include `auto`, `nextjs`, `nuxt`, `astro`, `nestjs`, `tanstack-start`, `custom`, and `bun`.

`app run --build-type` is local-dev oriented and supports `auto`, `bun`, and `nextjs`. It streams the local dev server and is not proof that the deployed app is reachable through public ingress.

`prisma.compute.ts` can set framework, entrypoint, HTTP port, env inputs, app root, region, and build settings. A config `build` block is accepted for every supported framework; all build types are config-backed (`nextjs`, `nuxt`, `astro`, `nestjs`, `tanstack-start`, `custom`, `bun`; `hono` builds through the `bun` strategy). For Nuxt, Astro, and NestJS the framework strategy supplies the default build command and output, so a `build` block is optional and normally unnecessary, but it overrides those defaults when present. Only `custom` requires one.

Config snippets below assume:

```typescript
import { defineComputeConfig } from "@prisma/compute-sdk/config";
```

## Universal Runtime Requirements

Compute needs a server process:

- It must listen on the deployed HTTP port. `@prisma/cli app deploy` defaults to the framework's default HTTP port (3000 for most frameworks, 4321 for Astro) unless `--http-port` is passed.
- It must bind on all interfaces. Do not hard-code `localhost` or `127.0.0.1` for a deployed server; use `0.0.0.0`, `server.host: true`, or the framework equivalent.
- It must have a deployable entrypoint or recognized framework output.
- It must not rely on a preview-only command such as `vite preview`.
- It must receive env vars through `--env`, project env, branch env, or external automation.

Check host and port together. A listener on the right port but bound to loopback can appear ready while public ingress cannot reach it.

## Next.js

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy --framework nextjs --env .env
```

`next.config.ts` must include standalone output:

```typescript
import type { NextConfig } from "next"

const nextConfig: NextConfig = {
  output: "standalone",
}

export default nextConfig
```

Do not pass `--entry` with `nextjs`; the CLI derives the runtime entrypoint from framework build output.

Do not set `HOSTNAME=localhost` or `HOSTNAME=127.0.0.1` in deploy env. If the standalone server host is overridden, use `0.0.0.0`.

## Hono

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy \
  --framework hono \
  --http-port 8080 \
  --env .env
```

Config shape:

```typescript
export default defineComputeConfig({
  app: {
    framework: "hono",
    entry: "src/index.ts",
    httpPort: 8080,
    env: ".env",
  },
});
```

Project expectations:

- `package.json` has `main` or `module` pointing at the entrypoint, or deploy passes `--entry src/index.ts`
- server uses `@hono/node-server`
- code reads `process.env.PORT` and defaults to the same port used by `--http-port`
- code does not set `hostname` to `localhost` or `127.0.0.1`; if hostname is set explicitly, use `0.0.0.0`

Example runtime shape:

```typescript
const rawPort = (process.env.PORT ?? "").trim()
const parsedPort = rawPort.length > 0 ? Number(rawPort) : Number.NaN
const port = Number.isInteger(parsedPort) ? parsedPort : 8080
serve({ fetch: app.fetch, port })
```

## NestJS

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy --framework nestjs --env .env
```

Config shape:

```typescript
export default defineComputeConfig({
  app: {
    framework: "nestjs",
    env: ".env",
  },
});
```

Project expectations:

- detection uses `nest-cli.json` or the `@nestjs/core` dependency; pass `--framework nestjs` when neither signal is present
- `src/main.ts` or the compiled runtime must start an HTTP server
- read `process.env.PORT` and default to the same port used by `--http-port`
- omit the host argument in `app.listen(port)` or pass `"0.0.0.0"`; do not pass `"localhost"` or `"127.0.0.1"`
- use `app build --build-type nestjs` for a Compute artifact check; `app run --build-type nestjs` is not supported, so use the Nest dev server locally

Example runtime shape:

```typescript
const port = Number(process.env.PORT ?? "3000")
await app.listen(port)
```

## TanStack Start

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy --framework tanstack-start --env .env
```

Expected `vite.config.ts` shape:

```typescript
import { defineConfig } from "vite"
import viteReact from "@vitejs/plugin-react"
import { tanstackStart } from "@tanstack/react-start/plugin/vite"
import { nitro } from "nitro/vite"

export default defineConfig({
  plugins: [tanstackStart(), nitro(), viteReact()],
})
```

Preserve these details:

- keep `nitro` in `dependencies`
- keep `import { nitro } from "nitro/vite"`
- keep `nitro()` in the Vite plugin list
- keep the React Vite plugin after `tanstackStart()`
- keep Nitro on its default node server preset; do not switch to edge, static, Cloudflare, or another non-Node preset for Compute

The build command is `vite build`. The build must produce `.output/server/index.mjs`, and the production start shape is:

```json
{
  "scripts": {
    "build": "vite build",
    "start": "node .output/server/index.mjs"
  }
}
```

Do not deploy TanStack Start as a Bun entrypoint such as `src/router.tsx`. If `.output/server/index.mjs` is missing, fix the TanStack/Nitro build path.

Make sure Nitro does not bind only to localhost in deployment. If host env/config is customized, use the framework's all-interface host setting rather than `localhost`.

## Nuxt

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy --framework nuxt --env .env
```

Config shape:

```typescript
export default defineComputeConfig({
  app: {
    framework: "nuxt",
    env: ".env",
  },
});
```

Nuxt uses Nitro output at `.output/server/index.mjs`. Keep the Nitro preset compatible with a Node server runtime.

## Astro

Deploy shape:

```bash
bunx @prisma/cli@latest app deploy --framework astro --env .env
```

Config shape:

```typescript
export default defineComputeConfig({
  app: {
    framework: "astro",
    httpPort: 4321,
    env: ".env",
  },
});
```

Astro Compute-style server output usually needs:

```javascript
import { defineConfig } from "astro/config"
import node from "@astrojs/node"

export default defineConfig({
  output: "server",
  adapter: node({ mode: "standalone" }),
  server: { host: true },
})
```

## Bun, Elysia, and Plain Source Servers

Use the Bun deploy key for app shapes without a dedicated `--framework` value:

```bash
bunx @prisma/cli@latest app deploy \
  --framework bun \
  --entry src/index.ts \
  --http-port 8080 \
  --env .env
```

`app deploy` also treats `--entry <path>` without `--framework` as a Bun app deploy.

Requirements:

- pass `--entry` unless `package.json` `main` or `module` points at the runtime entrypoint
- ensure the entrypoint starts an HTTP server, not only exports handlers
- read `process.env.PORT` or align `--http-port` with the fixed listener port
- bind on all interfaces

Elysia example:

```typescript
const port = Number(process.env.PORT ?? "8080")
app.listen({ port, hostname: "0.0.0.0" })
```

## Custom Build Artifacts

Use `framework: "custom"` when the app is already built, or when a custom command produces a runnable Node artifact that Compute should stage as-is:

```typescript
export default defineComputeConfig({
  app: {
    framework: "custom",
    build: {
      command: "npm run build",
      outputDirectory: "build",
      entrypoint: "handler.js",
    },
    httpPort: 3000,
    env: ".env",
  },
});
```

Requirements:

- set both `build.outputDirectory` and `build.entrypoint`
- make `build.entrypoint` relative to `build.outputDirectory`
- ensure the artifact starts an HTTP server and binds on all interfaces
- use `command: null` only when the output directory already contains the deployable artifact

## SvelteKit and Other Frameworks

`@prisma/cli app deploy --framework` has no `svelte` framework key. Do not claim SvelteKit is directly deployable with that name.

For frameworks without a dedicated deploy key, use one of these paths:

- produce a Node server artifact and deploy with config-backed `framework: "custom"`, or through a supported prebuilt/SDK flow
- if the app has a plain Node/Bun server entrypoint, deploy that entrypoint through `--framework bun --entry <path>`

SvelteKit should use a Node adapter or another production server artifact. Do not use `vite preview` as the deployed runtime.

## Turborepo

Deploy concrete app packages, not the monorepo root by default. Prefer `prisma.compute.ts` at the repo root with one `apps` entry per deploy target.

Checklist:

- choose the app directory, such as `apps/api`
- run the workspace build from the correct root/package
- pass the app package's runtime entrypoint or framework
- pass the correct env file, which may live outside the app package
- keep branch env/database scope aligned with the deployed app

Example config:

```typescript
export default defineComputeConfig({
  apps: {
    web: { root: "apps/web", framework: "nextjs" },
    api: {
      root: "apps/api",
      framework: "bun",
      entry: "src/index.ts",
      httpPort: 3000,
      env: "packages/db/.env",
    },
  },
});
```

Deploy one target:

```bash
bunx @prisma/cli@latest app deploy api --branch feature/foo --json
```

Flag-only shape after confirming output paths:

```bash
bun run build
bunx @prisma/cli@latest app deploy \
  --framework bun \
  --entry apps/api/dist/src/index.js \
  --http-port 3000 \
  --env packages/db/.env
```

Verify the actual output path before using this command.
