Simple example for using gulp.js to compile TypeScript

GulpTypeScript

{
    var gulp = require('gulp'),
        tsc = require('gulp-tsc'),
        shell = require('gulp-shell'),
        seq = require('run-sequence'),
        del = require('del');

    var paths = {
        ts: {
            src: [
                'scripts/ts/*.ts'
            ],
            dest : 'scripts/'
        }
    }

    // Default
    gulp.task('default', ['build']);

    // Clean
    gulp.task('clean', function (cb) {
        del(paths.ts.dest + '/*.js', cb);
    })

    // Build
    gulp.task('build', function () {
        return gulp
            .src(paths.ts.src)
            .pipe(tsc({
                module: "CommonJS",
                sourcemap: true,
                emitError: false
            }))
            .pipe(gulp.dest(paths.ts.dest));
    });

    // ReBuild - Clean & Build
    gulp.task('rebuild', function (cb) {
        seq('clean', 'build', cb);
    });
}
