Compiling LEGO component is built-in with no extra installation; pretty straightforward.

LEGO_URL=</url/to/lego.min.js> npm exec lego <sourceDir> <targetDir> <options>

Would compile the LEGO components in sourceDir folder (recursively) into JS file in targetDir using lego.min.js from the declared URL and provided options.

  • sourceDir (default: bricks): either a LEGO component file or a directory (relative or absolute). If it’s a directory, it will recursively read all the .html files and compile them into the targetDir.

  • targetDir (default: dist): the path (relative or absolute) to a folder where all .js files are compiled.

  • options: The only option for now is -w. It relates to the watch config property and will rebuild your components when they change: npm exec lego -w <sourceDir> <targetDir>.
