Spawn task experiment

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

Run task in child process:

var makeItFaster = require('spawn-task-experiment').spawn;
 
gulp.task('whatever', makeItFaster(function() {
    var gulp = require('gulp');
    var sourcemaps = require('gulp-sourcemaps');
    var concat = require('gulp-concat');
    return gulp.src(['app/index.js', 'app/**/*.js'])
        .pipe(sourcemaps.init())
        .pipe(concat('all.js'))
        .pipe(sourcemaps.write('.'))
        .pipe(gulp.dest('.build/scripts'));
}));

Run task in worker pool:

var makeItFaster = require('spawn-task-experiment').workerPool();
 
gulp.task('whatever', makeItFaster(function() {
    var gulp = require('gulp');
    var sourcemaps = require('gulp-sourcemaps');
    var concat = require('gulp-concat');
    return gulp.src(['app/index.js', 'app/**/*.js'])
        .pipe(sourcemaps.init())
        .pipe(concat('all.js'))
        .pipe(sourcemaps.write('.'))
        .pipe(gulp.dest('.build/scripts'));
}));

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)
