Scratch Blocks is a library for building creative computing interfaces.
scratch-blocks is a library to create visual programming environment. It's used in block editor on Scratch. It's also fork of Blockly.
However, Scratch Team forked Blockly in 20161. Currently, there are ESM and most of developers use it. ESM is released 2015, so Blockly which was in 2016 hadn't used ESM, used Google Closure Library. After that, Blockly migrated to ESM, but Scratch Team didn't migrate to ESM. Google Closure Library is a very old architecture. It changes global namespace. And it's difficult to use it with Vite. So we needed to get Scratch Blocks which uses ESM, but Scratch Team is conservative and we think Scratch Team won't migrate and accept PR.
Then we forked Scratch Blocks. It is patched to migrate to ESM. Scratch Blocks can't work with Vite, in contrast it works with Vite!
