Standalone decompressor for browsers #25

Open sheffieldnikki opened 5 years ago

sheffieldnikki commented 5 years ago

It would be very helpful to include a pre-built standalone decompressor (and compressor?) for use in browsers #2 , as not everyone is familiar with Node.js.

Here is a unbrotli.js and unbrotli.min.js for use in browsers: unbrotli.zip unbrotli.min.js is a 92Kb download, or 59Kb if Brotli-compressed by your web server. Much of that is the base64-encoded dictionary.

Called with:

unbrotli(buffer, [outSize])

I built it with the following commands (Ubuntu 16.04):

apt-get install nodejs npm
sed -i "s/dictionary-data/dictionary-browser/" dec/dictionary.js
ln -s /usr/bin/nodejs /usr/bin/node
npm install -g browserify
npm install base64-js
browserify decompress.js --standalone unbrotli -o unbrotli.js

(I couldn't get tinyify or uglify to run without errors, so I used a separate Javascript-minifier.)

I also got an error in use compress.js. And I built this compress.js with your steps.
