Using of Credits API in JS (demo).
Requirements
Any OS (For example, Windows 10 is used)
Download CREDITS API files:https://github.com/CREDITSCOM/CS-API
Create a folder and copy the JS files there. Create an empty html file, for example, index.html
Credits API source code generation
Credits API source code generation
Open the folder where you downloaded CREDITS API from the GitHub, for example, in d:\credits\github\CS-API\
For example, thrift is downloaded (https://thrift.apache.org/download) in the folder: d:\thrift\ Execute commands:
D:\thrift\thrift.exe --gen js api.thrift
D:\thrift\thrift.exe --gen js general.thrift
The result of the work will be a folder with files: gen-js.
Generated files:
API.js
api_types.js
general_types.js
Changes in index.html
Adding CREDITS API Script Files:
Add connection to Thrift and request the balance

<script>
function run()
{
var url = "http://localhost:8081";
var transport = new Thrift.Transport(url);
console.log("debug step 1");
var protocol = new Thrift.Protocol(transport);
console.log("debug step 2");
var client = new APIClient(protocol);
console.log("debug step 3");
var PublicKeyFrom = "5B3YXqDTcWQFGAqEJQJP3Bg1ZK8FFtHtgCiFLT5VAxpe";
var BytePublicKeyFrom = from_b58(PublicKeyFrom);
console.log("debug step 4");
var obj = client.WalletBalanceGet(BytePublicKeyFrom);
console.log("debug step 5");
console.log(obj);
console.log("debug step 6");
document.getElementById('pc-id').innerText = PublicKeyFrom;
document.getElementById('bl-id').innerText = 'Integral: ' + obj.balance.integral + ', Fraction: ' + obj.balance.fraction;
}
function ready() {
run();
}
document.addEventListener("DOMContentLoaded", ready);
</script>
Checking the efficiency. Calling the WalletBalanceGet method
The result of the work will be the requested balance:
