# TypeScript [](https://gitter.im/microsoft/TypeScript?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://travis-ci.org/microsoft/TypeScript) [](https://dev.azure.com/typescript/TypeScript/_build/latest?definitionId=4&view=logs) [](https://www.npmjs.com/package/typescript) [](https://www.npmjs.com/package/typescript) [TypeScript](https://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the [playground](https://www.typescriptlang.org/play/), and stay up to date via [our blog](https://blogs.msdn.microsoft.com/typescript) and [Twitter account](https://twitter.com/typescript). ## Installing For the latest stable version: ```bash npm install -g typescript ``` For our nightly builds: ```bash npm install -g typescript@next ``` ## Contribute There are many ways to [contribute](https://github.com/microsoft/TypeScript/blob/master/CONTRIBUTING.md) to TypeScript. * [Submit bugs](https://github.com/microsoft/TypeScript/issues) and help us verify fixes as they are checked in. * Review the [source code changes](https://github.com/microsoft/TypeScript/pulls). * Engage with other TypeScript users and developers on [StackOverflow](https://stackoverflow.com/questions/tagged/typescript). * Join the [#typescript](https://twitter.com/search?q=%23TypeScript) discussion on Twitter. * [Contribute bug fixes](https://github.com/microsoft/TypeScript/blob/master/CONTRIBUTING.md). * Read the language specification ([docx](https://github.com/microsoft/TypeScript/blob/master/doc/TypeScript%20Language%20Specification.docx?raw=true), [pdf](https://github.com/microsoft/TypeScript/blob/master/doc/TypeScript%20Language%20Specification.pdf?raw=true), [md](https://github.com/microsoft/TypeScript/blob/master/doc/spec.md)).

Clone a copy of the repo: ```bash git clone https://github.com/microsoft/TypeScript.git ``` Change to the TypeScript directory: ```bash cd TypeScript ``` Install [Gulp](https://gulpjs.com/) tools and dev dependencies: ```bash npm install -g gulp npm install ``` Use one of the following to build and test: ``` gulp local # Build the compiler into built/local. gulp clean # Delete the built compiler. gulp LKG # Replace the last known good with the built one. # Bootstrapping step to be executed when the built compiler reaches a stable state. gulp tests # Build the test infrastructure using the built compiler. gulp runtests # Run tests using the built compiler and test infrastructure. # Some low-value tests are skipped when not on a CI machine - you can use the # --skipPercent=0 command to override this behavior and run all tests locally. # You can override the specific suite runner used or specify a test for this command. # Use --tests=<testPath> for a specific test and/or --runner=<runnerName> for a specific suite. # Valid runners include conformance, compiler, fourslash, project, user, and docker # The user and docker runners are extended test suite runners - the user runner # works on disk in the tests/cases/user directory, while the docker runner works in containers. # You'll need to have the docker executable in your system path for the docker runner to work. gulp runtests-parallel # Like runtests, but split across multiple threads. Uses a number of threads equal to the system # core count by default. Use --workers=<number> to adjust this. gulp baseline-accept # This replaces the baseline test results with the results obtained from gulp runtests. gulp lint # Runs eslint on the TypeScript source. gulp help # List the above commands. ``` ## Usage ```bash node built/local/tsc.js hello.ts ``` ## Roadmap For details on our planned features and future direction please refer to our [roadmap](https://github.com/microsoft/TypeScript/wiki/Roadmap).
