eos-altjs's Introduction

eos-altjs

Alternative library for talking to the eos api.

Features:

Entire source lives in a single file for easy reference
Only dependancy is eosjs-ecc for signing transactions
Errors don't get dropped on the floor

Limitations:

Many ABI types not yet supported
It uses all provided keys to sign instead of querying the API for the needed set
No wallet support

Example use

<pre style="width: 100%; height: 100%; margin:0px; "></pre>
