The minified/concatenated antlr4 javascript package
npm install antlr4-js-minThis repository only has the concatenated and uglified files of antlr4.
Because of the way antlr4 javascript was made, it uses a module loader to load a lot of files, which requires a lot of HTTP requests. Sadly, the official repo doesn't provide a minified version. You can get it from here :)
$ npm install antlr4-js-min --save
