Things to try

Minimal Self Hosting

If you would like to try running the rebol wasm on your own pages, and don't have the time to keep updating your code as changes occur, then it's best to store the various resources locally. This includes the .js and .wasm files.

Here's an example hosted on Gitlab. Just clone the repository using this link or

git clone

You can update the resources using this download script
