Lightweight JS library

[redeye86]

Hi,

for my needs i needed a simple converter that replaces unicode-emojis with emojione svgs. As the original library would have doubled the amount of data my page visitors need to download, i decided to create an own library that uses a space efficient data structure for only that special purpose. The lib has ~38kb / ~5kb gzipped file containing both, the algorithms and data.

It's definitely not well-tested and may require some polyfills for Non-ECMAScript-6-Browsers, but if someone is interested, look at my gists:

library only:

generator for the actual js file (to generate file for a folder containing code-point emoji files):

This is really great. Current official implementation is huge and slow.

While shortnameToImage looks optimized toshort is not. Therefore if I simply need to convert unicode text to the image I'm stuck with converting to short names and than to image. I'm not sure anybody really needs shortnames nowadays.

I really want to see simple toImage function without shortname support.
Maybe official library could be published modular I can target unicode->image and include only needed information.

Improvements were suggested in #627 and #489
