lint-filter

library1.7.3jsnpmunverified

A CLI tool that filters lint output (e.g., ESLint checkstyle) to show only errors/warnings on lines changed relative to a git branch (default master). Useful for gradually adopting strict lint rules without breaking existing code. Version 1.7.3 is stable, released 2016-5-17. Supports external formatters, environment variable configuration, and a 'list-files' subcommand for faster linting. Alternative to eslint-nibble or incremental linting approaches.

lint-filter

✓ npx lint-filter --help

✗ import lintFilter from 'lint-filter'

lint-filter is a CLI tool, not a library. Use npx or global install.

Shows how to install lint-filter, set up a minimal ESlint config, commit code, then see filtered lint output for only new lines.

npm install --save-dev lint-filter echo '{"rules":{"no-console":"error"}}' > .eslintrc.json # Create a file with lint errors echo 'console.log("hello");' > test.js git init && git add -A && git commit -m "init" # Introduce a change echo 'console.log("world");' >> test.js # Run eslint with checkstyle and pipe to lint-filter eslint . -f checkstyle | npx lint-filter

lint-filter --version

Debug

Known issues

gotchadiff-so-fancy compatibility: lint-filter may not detect lines correctly if you use diff-so-fancy. Works since v1.6.2.

fix

Upgrade to >=1.6.2 or avoid diff-so-fancy.

affects: <1.6.2

deprecatedThe 'require:' prefix for external formatters may not work as expected if the module path is relative.

fix

Use an absolute path or install the module globally.

affects: >=1.7.0

gotchaOnly lines that are changed, not context lines, are considered (since v1.6.3). This might miss errors on lines adjacent to changes.

fix

If you need context lines, consider writing a custom script or downgrade.

affects: >=1.6.3

Errors

Common errors & fixes

Error: Cannot find module 'bluebird'

Missing dependency bluebird (fixed in v1.0.1).

fix

Install lint-filter >=1.0.1 or manually install bluebird.

lint-filter: command not found

Global install or npx not used.

fix

Run 'npx lint-filter' or install globally with 'npm install -g lint-filter'.

Error: ENOENT: no such file or directory, open 'path/to/checkstyle-report.xml'

File path does not exist.

Ensure the file exists or pipe input via stdin.
