As of now we are not compressing the js bundle. Probably we add an option to the build command so the use can choose if he wants gzipping or not.

inb4 we should also do brotli

[reznord]

We have the option of using Zopfli as well. @kristoferbaxter can give more insights on this.

My 2 cents:

• Need to compress the output at build step: messing with native dependencies, probably means lots of new issues.
• We need to change simplehttp2server /superstatic to something production ready so that users can run npm run serve

[developit]

I don't think there's an h2 alternative for simplehttp2server, but we could use serve instead of superstatic. I think they might be looking into supporting the same config format?

[reznord]

We can go with zopfli + brotli for this.

COnsider using wasm version (if any) instead of the native C version. It would save everyone a tons of time

Makes sense @thangngoc89, consider:
