Prisma Streams Local Build

This directory contains the generated Node/Bun-compatible package artifacts for the published @prisma/streams-local runtime.

What Local Streams Is

Prisma Streams local is a trusted-development Durable Streams server intended for embedded workflows such as prisma dev.

It keeps all state in a single local SQLite database and supports the live / touch system, but it does not run the full production segmenting and object store pipeline.

The embedded local runtime always applies the built-in 1024 MB auto-tune preset, so Prisma CLI gets a predictable cache and concurrency budget and the same current HTTP surface, including GET /v1/server/_details.

Published runtime floor:

• Bun >=1.2.0
• Node.js >=22

Supported Package Surface

• @prisma/streams-local
• @prisma/streams-local/internal/daemon (internal Prisma CLI plumbing)

The full self-hosted server remains Bun-only and is not part of this local build surface.

Integrating It

1. Start a named local server from @prisma/streams-local.
2. Install your touch-enabled state-protocol profile via /_profile.
3. Feed normalized State Protocol change events into the server.
4. Use /touch/meta and /touch/wait to drive invalidation.

Programmatic example:

import { startLocalDurableStreamsServer } from "@prisma/streams-local";

const server = await startLocalDurableStreamsServer({
  name: "default",
  hostname: "127.0.0.1",
  port: 0,
});

console.log(server.exports.http.url);
console.log(server.exports.sqlite.path);

await server.close();

Daemon example:

import { fork } from "node:child_process";

const child = fork(require.resolve("@prisma/streams-local/internal/daemon"), [
  "--name",
  "default",
  "--port",
  "0",
], {
  stdio: "inherit",
});
