base-pipeline

base-methods plugin that adds pipeline and plugin methods for dynamically composing streaming plugin pipelines.

Install

Install with npm:

$ npm install base-pipeline --save

Usage

var base = require('base-methods');
var pipeline = require('base-pipeline');
var bfs = require('base-fs');

// create your application and add the plugin
var app = base()
  .use(pipeline())
  .use(bfs)

// plugins may return a function
app.plugin('a', function() {
  return through.obj(function(file, enc, next) {
    next(null, file);
  });
});

// or a stream
app.plugin('b', through.obj(function(file, enc, next) {
  next(null, file);
}));

// use registered plugins
app.src(['foo/*.hbs'])
  .pipe(app.pipeline(['a', 'b']))
  .pipe(app.dest('site/'))

Supported signatures

Array of registered plugin names:

// register plugins
app.plugin('a', function() {});
app.plugin('b', function() {});

// pipeline
app.src(['foo/*.hbs'])
  .pipe(app.pipeline(['a', 'b']))
  .pipe(app.dest('site/'))

List of registed plugin names:

// register plugins
app.plugin('a', function() {});
app.plugin('b', function() {});

// pipeline
app.src(['foo/*.hbs'])
  .pipe(app.pipeline('a', 'b'))
  .pipe(app.dest('site/'))

Stacked:

// register plugins
app.plugin('a', function() {});
app.plugin('b', function() {});
app.plugin('c', function() {});

// pipeline
app.src(['foo/*.hbs'])
  .pipe(app.pipeline('a'))
  .pipe(app.pipeline('b'))
  .pipe(app.pipeline('c'))
  .pipe(app.dest('site/'))

Functions that return a stream:

app.src(['foo/*.hbs'])
  .pipe(app.pipeline(function() {
    return through.obj(function(file, enc, next) {
      next(null, file);  
    })
  }))
  .pipe(app.pipeline(function() {
    return through.obj(function(file, enc, next) {
      next(null, file);  
    })
  }))
  .pipe(app.dest('site/'))

Streams:

In general, it's a best practice for plugins to return a function that returns a stream. This ensures that every time the function is called a new stream is returned.

app.src(['foo/*.hbs'])
  .pipe(app.pipeline(through.obj(function(file, enc, next) {
    next(null, file);  
  }))
  .pipe(app.pipeline(through.obj(function(file, enc, next) {
    next(null, file);  
  }))
  .pipe(app.dest('site/'))
