Spawn task experiment

Tests how fast it is to run gulp tasks in child processes

Run task in child process:

1var makeItFaster = require('spawn-task-experiment').spawn;
2
3gulp.task('whatever', makeItFaster(function() {
4	var gulp = require('gulp');
5	var sourcemaps = require('gulp-sourcemaps');
6	var concat = require('gulp-concat');
7	return gulp.src(['app/index.js', 'app/**/*.js'])
8		.pipe(sourcemaps.init())
9		.pipe(concat('all.js'))
10		.pipe(sourcemaps.write('.'))
11		.pipe(gulp.dest('.build/scripts'));
12}));

Run task in worker pool:

1var makeItFaster = require('spawn-task-experiment').workerPool();
2
3gulp.task('whatever', makeItFaster(function() {
4	var gulp = require('gulp');
5	var sourcemaps = require('gulp-sourcemaps');
6	var concat = require('gulp-concat');
7	return gulp.src(['app/index.js', 'app/**/*.js'])
8		.pipe(sourcemaps.init())
9		.pipe(concat('all.js'))
10		.pipe(sourcemaps.write('.'))
11		.pipe(gulp.dest('.build/scripts'));
12}));

Notes:

• All wrapped functions need to be self-contained
• Using worker pool prevents parent process exit, so it might be usable only when watch is running
• Worker pool starts re-using child processes only after maxConcurrentWorkers limit has been reached (default is cpus().length)
