Apps

Prisma.Compute deploys an application onto Prisma’s managed runtime. One resource covers the whole path: build (optional), upload, deploy, health-check, promote — see Deployments for the lifecycle.

Framework apps

Point path at the app and describe its build. The command runs locally, the output directory is archived and uploaded, and the entrypoint starts the server:

import * as Prisma from "alchemy/Prisma";

const app = yield* Prisma.Compute("api", {
  project,
  path: "./app",
  build: {
    command: "bun run build",
    outdir: ".output",
    entrypoint: "server/index.mjs",
  },
  port: 3000,
  healthCheck: { path: "/api/health" },
  env: {
    DATABASE_URL: connection.databaseUrl,
  },
  destroyOldDeployment: true,
});

The server must listen on PORT (injected at runtime). With build: "auto" — the default when path points at a recognizable app — alchemy detects the framework (Bun, Next.js, Nuxt, Astro, TanStack Start, NestJS) and derives the build for you.

app.url is the deployed endpoint.

Effect-native apps

Pass main and an Effect body instead of a build, and the app is bundled from your Stack file — same shape as an Effect-native Cloudflare Worker or Lambda:

export default Prisma.Compute(
  "api",
  { project, main: import.meta.filename },
  Effect.gen(function* () {
    const db = yield* Prisma.Connect(connection);
    const sql = yield* SQL.Postgres({ url: db.databaseUrl });

    return {
      fetch: Effect.gen(function* () {
        const users = yield* sql`SELECT * FROM users`;
        return yield* HttpServerResponse.json(users);
      }),
    };
  }).pipe(Effect.provide(Prisma.ConnectBinding)),
);

Custom domains

const domain = yield* Prisma.CustomDomain("api-domain", {
  app,
  hostname: "api.example.com",
});

Local dev

Under bun alchemy dev, dev.command runs your app locally (e.g. vite dev) with the same env the deployed app would see — including connection bindings, which resolve to the local dev database:

const app = yield* Prisma.Compute("web", {
  project,
  path: ".",
  dev: { command: "bun run dev" },
  env: { DATABASE_URL: connection.databaseUrl },
});
