See this issue for more details: Roadmap: TSLint → ESLint. If you're interested in helping with the TSLint/ESLint migration, please check out our OSS Fellowship program.
TSLint is an extensible static analysis tool that checks TypeScript code for readability, maintainability, and functionality errors. It is widely supported across modern editors & build systems and can be customized with your own lint rules, configurations, and formatters.
TSLint currently supports:
- an extensive set of core rules
- custom lint rules
- custom formatters (failure reporters)
- inline disabling and enabling of rules with comment flags in source code
- configuration presets (
tslint-react, etc.) and plugin composition
- automatic fixing of formatting & style violations
- integration with MSBuild, Grunt, Gulp, Atom, Eclipse, Emacs, Sublime, Vim, Visual Studio 2015, Visual Studio 2017, Visual Studio code (alternative: use this extension for TS <3.2), WebStorm and more
Installation & Usage
Please refer to the full installation & usage documentation on the TSLint website. There, you'll find information about
There is a sandbox environment for TSLint at palantir.github.io/tslint-playground, which can be used to test rules and see how TSLint works. Issues can be filed against
Custom Rules & Plugins
Custom rule sets from Palantir
Custom rule sets from the community
If we don't have all the rules you're looking for, you can either write your own custom rules or use rules implementations developed by the community. The repos below are a good source of custom rules:
git clone firstname.lastname@example.org:palantir/tslint.git --config core.autocrlf=input --config core.eol=lf
