# TypeScript
|
|
|
|
[TypeScript](http://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types, classes, and modules to JavaScript. TypeScript supports 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](http://www.typescriptlang.org/Playground), and stay up to date via [our blog](http://blogs.msdn.com/typescript) and [twitter account](https://twitter.com/typescriptlang).

## Building
|
|
|
|
In order to build the TypeScript compiler, ensure that you have [Git](http://git-scm.com/downloads) and [Node.js](http://nodejs.org/) installed.
|
|
|
|
Clone a copy of the repo:
|
|
|
|
```
|
|
git clone https://github.com/Microsoft/TypeScript.git
|
|
```
|
|
|
|
Change to the TypeScript directory:
|
|
|
|
```
|
|
cd TypeScript
|
|
```
|
|
|
|
Install Jake tools and dev dependencies:
|
|
|
|
```
|
|
npm install -g jake
|
|
npm install
|
|
```
|
|
|
|
Use one of the following to build and test:
|
|
|
|
```
|
|
jake local # Build the compiler into built/local
|
|
jake clean # Delete the built compiler
|
|
jake LKG # Replace the last known good with the built one.
|
|
# Bootstrapping step to be executed when the built compiler reaches a stable state.
|
|
jake tests # Build the test infrastructure using the built compiler.
|
|
jake runtests # Run tests using the built compiler and test infrastructure.
|
|
# You can override the host or specify a test for this command.
|
|
# Use host=<hostName> or tests=<testPath>.
|
|
jake runtests-browser # Runs the tests using the built run.js file. Syntax is jake runtests. Optional
|
|
parameters 'host=', 'tests=[regex], reporter=[list|spec|json|<more>]'.
|
|
jake baseline-accept # This replaces the baseline test results with the results obtained from jake runtests.
|
|
jake -T # List the above commands.
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```shell
|
|
node built/local/tsc.js hello.ts
|
|
```
