This is a rewrite of [Reactive-Extensions/RxJS](https://github.com/Reactive-Extensions/RxJS) and is the latest production-ready version of RxJS. This rewrite is meant to have better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.

Much like traffic laws, ignorance doesn't grant you immunity. ## Installation and Usage ### ES6 via npm ```sh npm install rxjs ``` It's recommended to pull in the Observable creation methods you need directly from `'rxjs'` as shown below with `range`. And you can pull in any operator you need from one spot, under `'rxjs/operators'`. ```ts import { range } from 'rxjs'; import { map, filter } from 'rxjs/operators'; range(1, 200).pipe( filter(x => x % 2 === 1), map(x => x + x) ).subscribe(x => console.log(x)); ``` ### CDN For CDN, you can use [unpkg](https://unpkg.com/): https://unpkg.com/rxjs/bundles/rxjs.umd.min.js The global namespace for rxjs is `rxjs`: ```js const { range } = rxjs; const { map, filter } = rxjs.operators; range(1, 200).pipe( filter(x => x % 2 === 1), map(x => x + x) ).subscribe(x => console.log(x)); ``` ## Goals - Smaller overall bundles sizes - Provide better performance than preceding versions of RxJS - To model/follow the [Observable Spec Proposal](https://github.com/zenparsing/es-observable) to the observable - Provide more modular file structure in a variety of formats - Provide more debuggable call stacks than preceding versions of RxJS ## Building/Testing - `npm run build_all` - builds everything - `npm test` - runs tests - `npm run test_no_cache` - run test with `ts-node` set to false ## Performance Tests Run `npm run build_perf` or `npm run perf` to run the performance tests with `protractor`. Run `npm run perf_micro [operator]` to run micro performance test benchmarking operator. ## Adding documentation We appreciate all contributions to the documentation of any type.
