eosplayer

Eosplayer is a bonding layer of eosjs, which is based on eosjs and provides better usability for the application layer. It can be used on both the node.js server and in a browser or Dapp wallet that already has Scatter installed.

log

there are 4 levels of log

• verbose
• info
• warning
• error

in the initial situation, the level verbose is closed, and info|warning|error are opened.

if you would like to disable all level, set the level filter to '-'.

when enable called, origin setting will be override (not append).

Enable/Disable Log Level in Browser

• open specific level of log : localStorage.debug = 'warning:*,info:*'
• open all : localStorage.debug = '*'

then, refresh the broswer

Enable/Disable Log Level in Prompt

Unix

• DEBUG=error:* node test.js

CMD

• set DEBUG=error:* & node app.js

PowerShell

• $env:DEBUG = "error:*"

Enable/Disable Log Level in program dynamically

const debug = require('debug');
debug.enable('error:*,warning:*,info:*');

(temporary in beta.11) these code should be placed after the require operation of eosplayer.

Usage of eosplayer (cli)

you can use call methods of eosplayer.chain by cli

install: npm i -g eosplayer use: eosplayer --help

Usage of eosplayer (for node.js)

1. install eosplayer
   npm i eosplayer --save or yarn add eosplayer
2. import eosplayer
   import * from 'eosplayer' or const Player = require('eosplayer')
3. extend Player to create the glue layer, implement methods : eosClient and getIdentity see scatterPlayer

   import Player from 'eosplayer'
   import Eos from 'eosjs'
   class MyPlayer extends Player {
           get eosClient() {
               if (!this._eosClient) {
                   this._eosClient = new Eos(myAwsomeConf);
               }
               return this._eosClient;
           }
   
           async getIdentity() {
               return { name: "myawsomename", authority: "active" }
           }
   }
   

4. there some out-of-box implementation of player
   1. if you wanna reading data of the chain or signing and sending messages to the chain.

   import { signPlayer } from 'eosplayer'
   

   2. if you need the player automatic fuse and switch node, readingPlayer is a good choice

   import { readingPlayer } from 'eosplayer'
   

5. have fun
