# Installation

```bash
yarn add @lifaon/rx-js-light
# or
npm install @lifaon/rx-js-light --save
```

Then you can import and use it:

```ts
import { of, pipe$$, map$$$ } from '@lifaon/rx-js-light';

const subscribe = pipe$$(of(1, 2, 3), [
  map$$$(value => `-> ${value}`),
]);
```

This library supports:

- **common-js** (require): transpiled as es5, with .cjs extension, useful for old nodejs versions
- **module** (esm import): transpiled as esnext, with .mjs extension (requires node resolution for external packages)

The library is ready to go and does not require transpiling nor bundling. **However** it has been optimized for three-shacking,
so you should use a bundler like rollup or webpack.

For rapid testing, [you can immediately play with rx-js-light on stackblitz](https://stackblitz.com/edit/typescript-5ksaqe?file=index.ts)
