Creating a Simple Build Task - Building Angular 2 Applications with Gulp - Part 7

This is part of an ongoing series about building Angular 2 TypeScript applications with Gulp. Start with Part 1, and then read Part 2, Part 3, Part 4, Part 6.

In previous parts of this series, we created a lot of different build tasks. One for validating the TypeScript, one for compiling the TypeScript, and a few tasks for copying JavaScript and HTML files. What if we want to run them all in one command? This article will show you how.

It is pretty simple to create a Gulp task which will run multiple other Gulp tasks:

gulp.task("build", ['buildTS', 'copyJSLibraries',

This creates a new Gulp task named build. The argument to the task is an array and each element of the array is a string which represents another Gulp task. We saw this approach with buildTS task built in Part 3. In that part, the tslint task was executed as part of the buildTS task. In this case, the build task does not have its own functionality it just combines together the existing tasks.

Run this task:

gulp build

You'll see something like this:

All the tasks are run, creating a build.

What's Next?

The next part of this series will show you how to delete everything in the build directory before creating the build. I call this approach a clean build.
