Grunt vs System.js: What are the differences?
Developers describe Grunt as "The JavaScript Task Runner". The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it, a task runner can do most of that mundane work for you—and your team—with basically zero effort. On the other hand, System.js is detailed as "Dynamic ES module loader". It is a Universal Module Loader for JavaScript. If you've used RequireJs or a CommonJs bundler in the past, you have probably created modules.Configurable module loader enabling dynamic ES module workflows in browsers and NodeJS.
Grunt and System.js can be categorized as "JS Build Tools / JS Task Runners" tools.
Grunt and System.js are both open source tools. Grunt with 12K GitHub stars and 1.54K forks on GitHub appears to be more popular than System.js with 9.75K GitHub stars and 852 GitHub forks.
Medium, Twitter, and Udemy are some of the popular companies that use Grunt, whereas System.js is used by Canopy, Compass Inc., and One Negócios. Grunt has a broader approval, being mentioned in 1032 company stacks & 2441 developers stacks; compared to System.js, which is listed in 3 company stacks and 4 developer stacks.
I could define the next points why we have to migrate:
- Decrease build time of our application. (It was the main cause).
- Also
jspm install
takes much more time thannpm install
. - Many config files for SystemJS and JSPM. For Webpack you can use just one main config file, and you can use some separate config files for specific builds using inheritance and merge them.
