@buildwithharbor/pier-sst

Deploy a Vite-built Pier API with SST's standard Lambda, Function URL, resource linking, Live bridge, and development process.

Register the package as an SST provider; do not import it as an application dependency.

export default $config({
  app() {
    return {
      home: "aws",
      name: "my-app",
      providers: {
        pier: {
          package: "@buildwithharbor/pier-sst",
          version: "0.1.1",
        },
      },
    };
  },
  async run() {
    const api = new pier.PierBackend("Api", {
      path: "apps/api",
    });

    return { api: api.url };
  },
});

Pier owns the generated Fetch runtime and AWS Lambda adapter. SST and the application retain ownership of infrastructure, resource links, and deployment.
