Building

Before sharing with users, we recommend that you build and compress Scratch Blocks. Building requires Python 2 and an internet connection as it uses Google's online Closure Compiler. Once you are ready, you can build by running the following in your console:

python build.py

This will export multiple files including:

msg/js/en.js
blockly_uncompressed_vertical.js
blockly_uncompressed_horizontal.js
blockly_compressed_vertical.js
blockly_compressed_horizontal.js
blocks_compressed.js

These can then be used in your project by updating the HTML of your application:

<script src="blockly_compressed_horizontal.js"></script>
<script src="blocks_compressed.js"></script>
<script src="msg/js/en.js"></script>
