majiayu000 Lintmesh
Unified linter runner. One command, JSON output, all issues sorted by file:line.
Usage
# Lint everything (default: eslint + oxlint + tsgo)
lintmesh --quiet
# Lint specific paths
lintmesh --quiet src/
# Select linters
lintmesh --quiet --linters eslint,oxlint
Always use --quiet to suppress stderr progress.

Patterns
# Error count
lintmesh --quiet | jq '.summary.errors'
# Files with issues
lintmesh --quiet | jq -r '.issues[].path' | sort -u
# Only errors
lintmesh --quiet | jq '[.issues[] | select(.severity == "error")]'
# Check if clean
lintmesh --quiet && echo "No errors"
When to Use
- After editing code: catch issues early
- Before committing: verify no regressions
- Debugging CI: reproduce locally with same format
