Lint to the Future (LTTF) v2.6.4 is a tool that helps progressively enable lint rules by adding file-based ignore directives to existing violations, then tracking cleanup via a dashboard. It supports ESLint, Ember templates, stylelint via plugins (e.g., lint-to-the-future-eslint). Active development with monthly releases. Unlike blanket ignore configs, it adds temporary per-file ignores, allowing new files to adhere to rules while old files are fixed incrementally. Requires Node >= 18.

Debug

Known issues

breakingRequires Node >= 18. Older versions may crash with syntax errors.

fix

Update Node.js to v18 or later.

affects: >=2.0.0

gotchaThe 'ignore' command only handles errors, not warnings. Warnings will be ignored.

fix

Configure your linter to treat warnings as errors if needed.

affects: >=2.0.0

deprecatedIn v2.5.0, the 'files' route was renamed to 'rule'. Old dashboard links may break.

fix

Update references from '/files' to '/rule' in your dashboard configuration.

affects: >=2.5.0

gotchaPlugins must be installed locally (not globally) and named 'lint-to-the-future-*'. Autoloading may miss plugins with different prefixes.

fix

Ensure plugin packages start with 'lint-to-the-future-' and are in node_modules.

affects: >=2.0.0

breakingThe --previous-results flag output format changed in v2.5.1 to fix a bug. Custom scripts relying on old format may break.

fix

Update any parsing logic for --previous-results output.
