Using Gulp with TypeScript

Install gulp and gulp-typescript. See package.json.

$ npm install --global gulp
$ npm install --save-dev gulp gulp-typescript

Config gulp. See gulpfile.js.

gulp.task('typescript', function() {
  var tsResult = gulp.src('ts/*.ts')
    .pipe(ts({
      target: 'ES5',
      declarationFiles: false,
      noExternalResolve: true
    }));

  tsResult.dts.pipe(gulp.dest('dist/tsdefinitions'));

  return tsResult.js.pipe(gulp.dest('dist/typescript'));
});
