Installation Instructions

Here are different ways you can install RxJs:

ES6 via npm

npm install rxjs

To import the entire core set of functionality:

import * as rxjs from 'rxjs';

rxjs.of(1, 2, 3);

To import only what you need using pipeable operators:

import { of } from 'rxjs';
import { map } from 'rxjs/operators';

of(1,2,3).pipe(map(x => x + '!!!')); // etc

• See Pipeable Operator Documentation for more information about pipeable operator.

To use with globally imported bundle:

const { of } = rxjs;
const { map } = rxjs.operators;

of(1,2,3).pipe(map(x => x + '!!!')); // etc

CommonJS via npm

If you receive an error like error TS2304: Cannot find name 'Promise' or error TS2304: Cannot find name 'Iterable' when using RxJS you may need to install a supplemental set of typings.

1. For typings users:

typings install es6-shim --ambient

2. If you're not using typings the interfaces can be copied from /es6-shim/es6-shim.d.ts.

3. Add type definition file included in tsconfig.json or CLI argument.

All Module Types (CJS/ES6/AMD/TypeScript) via npm
