Develop

Requires Node.js ≥ 20.18 and pnpm ≥ 10.

pnpm install
pnpm -r build
pnpm -r test
pnpm -r typecheck
pnpm lint

To work on a single package:

pnpm --filter aemet-client test
pnpm --filter aemet-mcp dev

The E2E suite (pnpm --filter aemet-client test:e2e) hits the real AEMET API and is skipped unless AEMET_API_KEY is set. CI runs it behind a repository secret.

Release

aemet-client is released by pushing a tag v<x.y.z> or aemet-client-v<x.y.z>. The release workflow checks the tag matches packages/aemet-client/package.json before publishing to npm via Trusted Publishing (OIDC, no token).
aemet-mcp is released by pushing a tag aemet-mcp-v<x.y.z> using the same Trusted Publishing setup. pnpm publish rewrites the workspace:^ dependency on aemet-client to a real semver range.
