JS encode support

[blacha]

I have a NodeJS lambda that I would like to download decompress a LERC file modify it then recompress it back into LERC, but the JS API only has decode.

Do you have any plans on adding support for encode to javascript/wasm?

Sorry, currently we have no plans for supporting Lerc encode in JS / wasm. First, the size of the wasm file would likely double or triple in size, while most folks only need the decode. Second, even if the likelihood for such bugs is low, we would have to make sure that the JS / wasm encode cannot produce bad data.
