Use when setting up a local ElevenLabs dev environment for a TTS/voice project and you need SDK mocking, hot reload, quota-aware iteration, and audio-output testing that does not burn character quota during development. Trigger with "elevenlabs dev setup", "elevenlabs local development", "elevenlabs dev environment", "develop with elevenlabs", "test elevenlabs locally".

A developer runs the local dev loop and encounters a `MODULE_NOT_FOUND` error when importing the official ElevenLabs JavaScript library. What command resolves this missing package issue?

The instructions your model reads when the skill loads.
Set up a fast, cost-effective local development workflow for ElevenLabs audio
projects. The loop centers on three moves — mock the SDK so unit tests never
burn character quota, gate real API calls behind an explicit
ELEVENLABS_INTEGRATION=1 flag, and select a cheaper model in dev while keeping
the high-quality model for production — with tsx watch hot reload and a quota
checker to round out the cycle.
Follow the high-level flow below to scaffold the project, then drill into references/implementation.md for the full code of every step and references/examples.md for worked end-to-end runs.
Before starting, confirm your environment is ready:
elevenlabs-install-auth setup is complete, so the SDK
(@elevenlabs/elevenlabs-js) is installed and ELEVENLABS_API_KEY is
available in .env.local.npm or pnpm.vitest installed as the test runner (recommended) — it powers the mock
layer and the integration-test guard.Work through the six steps in order. Each is summarized here; the full code for every step lives in references/implementation.md.
Project structure — lay out src/elevenlabs/ (client, config, tts),
tests/__mocks__/ and tests/fixtures/sample.mp3, a git-ignored output/,
and .env.local / .env.example. Full tree in the reference.
Environment configuration — write an environment-aware config.ts that
picks the model and output format by NODE_ENV. This is the essential
skeleton:
test cases passed, vs 11 / 21 without
