A Javascript task pipeline library built on top of [RxJS](https://github.com/ReactiveX/rxjs). It helps you manage complex (possibly async) operations on collections (or streams) of entities. A common example is performing a series of tasks on a list of files (compiling sass to css or markdown to html).

```

npm i rxline

```

## Usage

Super basic example:

```javascript

import { line } from 'rxline';

line([1, 2, 3, 4])

  .pipe(x => x * 2)

  .pick(x => x > 3)

  .collect(console.log);

```

More real-life example:

```javascript

import { concurrently } from 'rxline';

import { files, pathMatch, 

         readFile, writeFile, 

         mapExt, mapContent, mapRoot } from 'rxline/fs';

files('.')                                                   // --> all files in current directory (and sub-directories)

  .pick(pathMatch(/\.js$/))                                  // --> pick javascript files

  .peek(f => console.log('-->' + f.path))                    // --> log each file path

  .pipe(readFile(),                                          // --> read contents of the file

        mapContent(c => ({ lines: c.split('\n').length })),  // --> map its content to an object with number of lines in it

        mapContent(c => JSON.stringify(c, null, 2)),         // --> also stringify the json object

        mapExt(() => '.json'),                               // --> change extension to `.json`

        mapRoot(() => '.meta'),                              // --> change root directory to `.meta`

        writeFile())                                         // --> write the files

  .process(concurrently);                                    // --> all in parallel.

```

## Why?

Because Gulp felt too opaque for me. I needed to be more in control.
