Issues

You can test this locally with npm:

first:

npm install

then

npm run dev

You'll need to set a value for PUBLIC_TRUSTED_HOST in the .env file, e.g.:

PUBLIC_TRUSTED_HOST="http://localhost:8080"

There is a sample.env for your reference. you can: cp sample.env .env and then edit that .env file.

Test harness

A local test page is in test/index.html. It embeds the runner in an iframe and lets you send programs via postMessage. With PUBLIC_TRUSTED_HOST="http://localhost:8080" in your .env and npm run dev running, open a second terminal and run:

npm run test-ui

Then visit http://localhost:8080 and click ▶ Run.
