Once npm install was executed, you can either do crafty run or crafty watch

While developing, prefer crafty watch

This will run Crafty in watch mode, in this mode, each change you make to your files will be detected and the relevant assets will be compiled.

This works with the following :

  • A change in a CSS file
  • A change in a JavaScript or TypeScript file
  • Adding or replacing images
  • in any runner (Gulp, Webpack and rollup.js)

It’s strongly recommended to let it run in the background in your IDE while you’re developing, it streamlines the process a lot !
