TSLint

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 supports:

• custom lint rules
• custom formatters (failure reporters)
• inline disabling and enabling of rules with comment flags
• configuration presets (tslint:latest, 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, WebStorm and more

Installation & Usage

Please refer to the full installation & usage documentation on the TSLint website. There, you'll find information about

• configuration,
• core rules,
• core formatters, and
• customization of TSLint.

• ESLint rules for TSLint - Improve your TSLint with the missing ESLint Rules
• tslint-microsoft-contrib - A set of TSLint rules used on some Microsoft projects
• codelyzer - A set of tslint rules for static code analysis of Angular TypeScript projects
• vrsource-tslint-rules
• tslint-immutable - TSLint rules to disable mutation in TypeScript
• tslint-consistent-codestyle - TSLint rules to enforce consistent code style in TypeScript

Creating a new release

1. Bump the version number in package.json and src/linter.ts
2. Add release notes in CHANGELOG.md
3. yarn verify to build the latest sources from a clean state
4. Commit with message Prepare release <version>
5. Run npm publish
6. Create a git tag for the new release and push it (see existing tags here)
