Development

This package can be used both as an ES6 Node.js module and a Browser library.

Node.js imports use the file src/speech-events.js.

NOTE: Currently this package can only be used under Node.js apps compatible with ES6.

Webpack is used to build the browser-compatible lib/speech-events.js file which is later uglified (using uglify-js) into dist/speech-events.min.js.
