Connect

Source: src/Prisma/Connect.ts

Bind a Connection to a Prisma Compute app, AWS Lambda Function, Cloudflare Worker, or Cloudflare Container and obtain the typed runtime client.

Connect is a single identifier that is simultaneously the binding’s Context tag, its type, and the callable — yield* Prisma.Connect(connection).

Provide Prisma.ConnectBinding on the host implementation so Alchemy can register the deploy-time binding and resolve the client at runtime.

Binding a Connection

Use a connection inside Prisma Compute

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)),
);

Use a connection inside a Cloudflare Container

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

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

A container is a real process with no workerd bindings, so the connection travels as plain environment variables — the same channel Prisma Compute and Lambda use. Start the container with Cloudflare.Containers.layer(Api, { enableInternet: true }) so it can reach the database. (Hyperdrive, by contrast, is a workerd binding and is unavailable inside a container.)
