merge-stream 2.0.0

The merge-stream package is a popular npm module which is used to merge or interleave several other streams. By doing this, users can easily control and manage multiple data sources, allowing for more organized and efficient stream operations. It offers a unique capability to add streams dynamically and quickly identify whether the merged stream is empty. Having a merged stream is beneficial for aligning data sequences and facilitating simultaneous events.

To utilize merge-stream in your JavaScript projects, you need to first install it using npm. Once installed, you can create a new stream using the mergeStream() method by passing your desired streams as parameters.

A fundamental JavaScript code example demonstrating how to merge streams using merge-stream is as follows:

var stream1 = new Stream();
var stream2 = new Stream();

var merged = mergeStream(stream1, stream2);

var stream3 = new Stream();
merged.add(stream3);
merged.isEmpty();  //returns false if the merged stream is not empty.

In addition, you can also make use of merge-stream in a Gulp task for combining parts of tasks. Here's an example that shows how to do that:

const gulp = require('gulp');
const htmlValidator = require('gulp-w3c-html-validator');
const jsHint =  require('gulp-jshint');
const mergeStream =  require('merge-stream');

function lint() {
  return mergeStream(
    gulp.src('src/*.html').pipe(htmlValidator()).pipe(htmlValidator.reporter()),
    gulp.src('src/*.js').pipe(jsHint()).pipe(jsHint.reporter())
  );
}

gulp.task('lint', lint);
