Reuse the api object for all transactions; it caches ABIs to reduce network usage. Only call new eosjs_api.default(...) once.

If you would like readable source files for debugging, change the file reference to the -debug.js files inside dist-web/debug directory. These files should only be used for development as they are over 10 times as large as the minified versions, and importing the debug versions will increase loading times for the end user.

IE11 and Edge Support

If you need to support IE11 or Edge you will also need to install a text-encoding polyfill as eosjs Signing is dependent on the TextEncoder which IE11 and Edge do not provide. Pass the TextEncoder and TextDecoder to the API constructor as demonstrated in the ES 2015 example. Refer to the documentation here to determine the best way to include it in your project.
