Part 1. Interoperable API for Cocos-BCX Chain System-BCXJS

The Javascript API for integration with COCOS-BCX-based blockchain using the COCOS-BCX RPC API.

Preparation:

Node.js 8.9.3 or higher version.

Build:

Use npm install to install local dependencies. Run building npm run dev.

Browser Distribution

Use the building to issue npm run release. The unpacked building shall be found at ./build.

NPM

Use the building to issue npm run release-npm. The unpacked building shall be found at./build-npm.

Import

Browser

 <script type="text/javascript" src="bcx.min.js"></script>

NPM

NPM, which works well with modules packagers such as webpack or Browserify, is highly recommended when building large applications with bcxjs.

# The latest stable version
$ npm install bcxjs-api

ES6 module syntax import is supported when there is a converter like Babel.

import BCX from "bcxjs-api"

Start:

Instantiating the class library object

var bcx=new BCX({
		default_ws_node:”ws://XXXXXXXXX” //node rpc address, optional. If you do not specify this, it will automatically connect to the fastest node in ws_node_list
		ws_node_list:[{url:"ws://xxxxxxx",name:"xxxxx"}]//API server node list, required
		faucet_url:"http://xxx.xxx.xxx.xxx:xxxx", //Registration
		networks:[{
			core_asset:"xxx",//core asset symbol
			chain_id:"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"//chain id 
		}], 
		auto_reconnect:false,//Whether to connect automatically when RPC is disconnected, the default is true
		app_keys:["xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"],//Contract authorization. Do not need to configure this if there is no contract authorization
		real_sub:true//true:real-time subscription,false:blockchain subscription,the frequency of subscription notification is the frequency block production  
		sub_max_op:13//Maximum number of OP processed at subscription
});

Instance of call - transfer

bcx.transferAsset({
     to:"test2",
     amount:1,
     assetId:"COCOS",
     memo:""
}).then(res=>{
     console.log('transferAsset res',res);
})

API User Guide

1.There is one optional parameter callback unless otherwise specified

The result returned by callback is an Object with an structure of {code:0,message:""}. If it is code=1, it means the result is success, and there is no message status description. If it is Code!=1, it means that the result is failure, the message is the description of the failure status.

2.There is only one parameter unless otherwise specified. The parameter is an object that contains all relevant parameters, including callback.

Example:

bcl.getPrivateKey().then(res=>{});

3.In addition to the subscription interface, other interfaces return a promise object when not passing callback parameter.

4.The parameter type of the interface is a string unless otherwise specified.

5.The parameter of the interface cannot be empty unless otherwise specified. Callback is an optional parameter.

6.The searching interface returns a data instance: {code:1,data:[]}

7.The data returned by other interfaces will have an additional data field trxData with a value of one object.

Example:

trx_data:{
 block_num:*****,//Block height
 trx_id:"************************"//Transaction ID
}

8.If a non-query interface involves associated ID business (such as the ID generated by creating the NH asset), the data returned will contain the data object.

//Example

data:{
  real_running_time: 387//Running time
  result: "4.2.288"//Associated business id
}
