How to run a npm script command from inside a gulp task?

package.json

scripts: 

{

    tsc: tsc -w

}

gulpfile.js

gulp.task('compile:app', function(){

  return gulp.src('src/**/*.ts')

    .pipe(/*npm run tsc*/)

    .pipe(gulp.dest('./dist'))

    .pipe(connect.reload());

});

I want to do this because running npm run tsc does not give me any error but if I use gulp-typescript to compile .ts then I get bunch of errors.

You can get the equivalent using gulp-typescript

var gulp = require('gulp');

var ts = require('gulp-typescript');



gulp.task('default', function () {

  var tsProject = ts.createProject('tsconfig.json');



  var result = tsProject.src().pipe(ts(tsProject));



  return result.js.pipe(gulp.dest('release'));

});



gulp.task('watch', ['default'], function() {

  gulp.watch('src/*.ts', ['default']);

});

Then on your package.json

scripts: {

  gulp: gulp,

  gulp-watch: gulp watch

}

Then run

npm run gulp-watch

~~Alternatively using shell~~

var gulp = require('gulp'); var shell = require('gulp-shell'); gulp.task('default', function () { return gulp.src('src/**/*.ts') .pipe(shell('npm run tsc')) .pipe(gulp.dest('./dist')) .pipe(connect.reload()); });

gulp-shell has been blacklisted you can see why here

Another alternative would be setting up webpack.
