How do you build?
npm i
npx tsc regexfree.ts
Copy/paste the contents of regexfree.js into the second <script>...</script> tags in index.html.
Why isn't there a build script?
I'm lazy.
Why is everything in one file?
I heard there was a perf advantage. It also makes the file simple to download and use offline, I suppose.
You should support my use case
Sure, open an issue.
