# TSLint
|
|
|
|
:warning: __TSLint is deprecated.__
|
|
|
|
> See this issue for more details: [Roadmap: TSLint → ESLint](https://github.com/palantir/tslint/issues/4534). If you're interested in helping with the TSLint/ESLint migration, please check out our [OSS Fellowship](https://medium.com/palantir/fellowships-for-open-source-developers-3892e6b75ee1) program.
|
|
|
|
TSLint is an extensible static analysis tool that checks [TypeScript](https://github.com/Microsoft/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:latest`, `tslint-react`, etc.) and plugin composition
|
|
- automatic fixing of formatting & style violations
|
|
- integration with [MSBuild](https://github.com/joshuakgoldberg/tslint.msbuild), [Grunt](https://github.com/palantir/grunt-tslint), [Gulp](https://github.com/panuhorsmalahti/gulp-tslint), [Atom](https://github.com/AtomLinter/linter-tslint), [Eclipse](https://github.com/palantir/eclipse-tslint), [Emacs](https://www.flycheck.org/), [Sublime](https://packagecontrol.io/packages/SublimeLinter-contrib-tslint), [Vim](https://github.com/scrooloose/syntastic), [Visual Studio 2015](https://marketplace.visualstudio.com/items?itemName=MadsKristensen.WebAnalyzer), [Visual Studio 2017](https://marketplace.visualstudio.com/items?itemName=RichNewman.TypeScriptAnalyzer), [Visual Studio code](https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-typescript-tslint-plugin) (alternative: use [this extension](https://marketplace.visualstudio.com/items?itemName=eg2.tslint) for TS <3.2), [WebStorm](https://www.jetbrains.com/webstorm/help/tslint.html) and [more](https://palantir.github.io/tslint/usage/third-party-tools/)

## TSLint Playground
|
|
|
|
There is a sandbox environment for TSLint at [palantir.github.io/tslint-playground](https://palantir.github.io/tslint-playground/), which can be used to test rules and see how TSLint works. Issues can be filed against `tslint-playground` [here](https://github.com/palantir/tslint-playground).
