lint

js/cli/lint.md

fino lint runs Fino's built-in lint diagnostics over JavaScript and TypeScript-family source files. Use it to catch supported style and correctness issues without wiring a separate linter into the project:

fino lint src
fino lint --fix 'src/**/*.ts'

With no file inputs, the command recursively scans the current working directory. Explicit inputs can be files, directories, or glob patterns. A directory input lints supported source files below that directory using the same discovery rules as fino fmt.

Command Reference

Source discovery accepts .js, .mjs, .cjs, .jsx, .ts, .mts, .cts, and .tsx. Hidden directories and common dependency, generated, cache, and build-output directories such as node_modules, dist, build, docs, target, and coverage are skipped.

The release baseline does not include a project lint config file, a per-project ignore file, or a configurable rule set. Missing explicit directories and explicit glob patterns that match no supported source files are command errors.

Use --fix for fixes the linter can apply safely. It does not run formatting, so run fino fmt separately when you want formatting changes too:

fino lint --fix src
fino fmt src
