# Runtime

This is a runtime library for [TypeScript](http://www.typescriptlang.org/) that contains all of the TypeScript helper functions.

# Installing

For the latest stable version:

```
npm install tslib
```

# Usage

Set the `noEmitHelpers` compiler option on the command line or in your tsconfig.json:
```
tsc --noEmitHelpers
```

Import tslib in your TypeScript sources:
```ts
import * as tslib from "tslib";

const __extends = tslib.__extends;
const __awaiter = tslib.__awaiter;

...
```

Or use it globally on the web via `<script src="tslib.js"></script>`:

```ts
// <reference path="tslib.global.d.ts" />
var __extends = __tslib.__extends;
var __awaiter = __tslib.__awaiter;

...
```
