CDN Integration

[ChrisCates]

Overview

This is a rather simple semantic to add to the project.
Currently, the documentation asks users to clone and build the project from scratch.

As seen here: https://eosio.github.io/eosjs/latest/basic-usage/browser

Of course, a CDN is much simpler and easier to use... You can just pop in a script and you're good to go... However, it would be nice to have some DevOps integrations to automatically deploy new releases on every RC or commit to master.

Suggested Tasks

1. Update a CDN (ie: JSDelivr) with the latest build from yarn build-web via CI.

2. Update documentation to point users to be able to use the CDN over having to manually build the web files from scratch.
