Thanks @developit

@developit Can you also publish preact-compat please?

[developit]

@mohsen1 hmm - might be worth publishing a combined. Preact-compat depends on PropTypes, which is awkward to use from a CDN.

[mohsen1]

With H/2 it works beautifully. We are requiring super small modules from CDN.

Also a quick question, if we are not using PropTypes (because of TypeScript) can we just avoid including it?

[developit]

@mohsen1 I believe so, yes. The checks would never run, so it would just be an unreferenced object. I don't quite remember the process to get a lib added here but I'll look into it when I get a chance.

@developit

I'm not familiar with the process of adding a new lib to CDNjs otherwise I would help. Can you take a look at adding preact compat to CDNjs? It would help our app a lot. Thanks!
