Checking Your Code

dagger check

Runs all checks in your workspace in parallel. Exits non-zero if any check fails. Results are identical on your laptop, in CI, and in the cloud.

List checks

dagger check -l

Filter checks

dagger check eslint:*          # all checks from a module
dagger check vitest:test       # a single check
dagger check *:lint            # pattern across modules

Stop on first failure

By default every check runs so you see all failures at once. To cancel the rest as soon as one fails:

dagger check --failfast

Checks and generators

A generator can be run as a check to confirm its output is up to date. To control which kind runs:

dagger check --no-generate     # only annotated check functions
dagger check --generate        # only generators-run-as-checks

Per-environment checks

Run checks with a named environment overlay applied:

dagger --env staging check

In CI

# GitHub Actions
- run: dagger check

To automate checks on every push without configuring runners, see Triggers.
