How to run tests and servers with a saved key group with Envlatch

Save several keys as a named group and launch tests or a backend with one flag.

Short answer: Create a group with envlatch groups create "Backend" --using OPENAI_API_KEY --using GITHUB_TOKEN; then run envlatch run --using "Backend" -- npm test; start the server with envlatch run --using "Backend" -- python3 server.py. All steps.

Who it is forA backend developer whose test suite needs both an OpenAI key and a GitHub token.

The problemRepeating several key flags on every command is error-prone.

The outcomeA reusable group that injects the same set of keys every time.

What you need first

  • macOS
  • Swift toolchain to build from source

Steps

  1. Create a group with envlatch groups create "Backend" --using OPENAI_API_KEY --using GITHUB_TOKEN
  2. Run envlatch run --using "Backend" -- npm test
  3. Start the server with envlatch run --using "Backend" -- python3 server.py
  4. List groups with envlatch groups

Prompt for your agent

Create an EnvLatch group named <name> with <keys>, run `envlatch run --using "<name>" -- npm test`, and report whether tests pass. Confirm no .env file was used.

Caveat. Group membership is by exact key names, so renaming a key breaks the group.
