deno_lint

A Rust crate for writing JavaScript and TypeScript linters.

This crate powers deno lint, but is not Deno specific and can be used as a standalone crate.

It ships with a set of built-in rules, including a recommended set that is enabled by default and requires no configuration.

Supported rules

The list of available rules and their documentation is hosted at docs.deno.com/lint/rules.

Example

Developing
