Lensflare

Lensflare is a local observability workspace for inspecting logs and traces while you build. It includes a web UI, a local server, a desktop app, and a small Effect SDK that sends development telemetry to your local Lensflare dataset.

Quick Start

Install dependencies:

pnpm install

Run the local server and web app:

pnpm dev

Run the desktop app:

pnpm dev:desktop

Build and test:

pnpm build
pnpm test

Effect SDK

The first public package is @lensflare.dev/effect, an Effect layer for sending logs and traces to Lensflare during local development.

pnpm add effect @lensflare.dev/effect

import { Effect } from "effect";
import { Lensflare } from "@lensflare.dev/effect";

const program = Effect.gen(function* () {
  yield* Effect.log("hello from Lensflare");
});

Effect.runPromise(program.pipe(Effect.provide(Lensflare.layer("dev"))));

See packages/effect for package documentation.

Development

This repository uses Node 24 and pnpm 10. The main workspace commands are:

pnpm dev
pnpm dev:web
pnpm dev:server
pnpm dev:desktop
pnpm check
pnpm typecheck
pnpm test
pnpm build

Before writing Effect code, consult the local Effect guidance described in AGENTS.md.
