This is a fork of gulp-concat and does this:

Concatenates handlebars/mustache templates into a single .js file, where template files are mapped to a global template object (based on the filename of the template).

The reasoning is that we want to interpolate variables and texts (which comes from a rest-api), and compile the templates at runtime in the browser. Also, we need to strip newlines and whitespace from our templates (to make it fit inside a javascript string) I could not find a gulp-plugin to do exactly (and only) this, so then we fork! :)

// result will be something like this:
MyApp.templates["welcome"] = 'Welcome {{user.name}}!';
MyApp.templates["goodbye"] = 'Goodbye {{user.name}}!';
// then it's up to you to parse/compile the templates in JS
// psuedo-code example (MyApp.parse wraps Handlebars.compile()):
var data = {
  user: {
    name: 'Hal'
  }
}
var welcomeHtml = MyApp.parse(MyApp.templates.welcome, data);
$('body').append(welcomeHtml);
// such amaze!

var concat = require('gulp-hbs-concat');

gulp.task('templates', function(){
  gulp.src('paths/glob to templates')
    .pipe(hbsconcat('templates.js', {newLine: '\n', prefix: 'MyApp.templates', postfix: ';'}))
    .pipe(gulp.dest('js/src/'));
});
// templates.js should now be baked with uglify

This will concat files by your operating systems newLine. It will take the base directory from the first file that passes through it.

Files will be concatenated in the order that they are specified in the gulp.src function. For example, to concat ./lib/file3.js, ./lib/file1.js and ./lib/file2.js in that order, the following code will create a task to do that:

var concat = require('gulp-concat');

gulp.task('scripts', function() {
  gulp.src(['./lib/file3.js', './lib/file1.js', './lib/file2.js'])
    .pipe(concat('all.js'))
    .pipe(gulp.dest('./dist/'))
});

To change the newLine simply pass an object as the second argument to concat with newLine being whatever (\r\n if you want to support any OS to look at it)

For instance:

.pipe(concat('main.js', {newLine: ';'}))
