JSPM – tron-tx-decoder-tronweb@3.2.0

Package Exports

tron-tx-decoder-tronweb
tron-tx-decoder-tronweb/decoder.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tron-tx-decoder-tronweb) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Initialization

const TronTxDecoder = require('tron-tx-decoder-tronweb');
const Tronweb = require('tronweb');

const tronweb = new TronWeb({
    network: 'shasta',
    fullHost: 'https://api.shasta.trongrid.io',
    apiUrl: 'https://shastapi.tronscan.org/api',
    eventServer: 'https://api.shasta.trongrid.io',

const decoder = new TronTxDecoder({ tronweb });

Decode Input:

Decode function input parameters by passing transaction id.

async function decodeTxInput(txId){
    const decodedInput = await decoder.decodeInputById(txId);
    return decodedInput;
}

decodeTxInput("0c739761b34a891b3bbecd528302de827736660d76c62dacf8d3a9ebe7dade08");

Output:

{ 
    methodName: 'submitTheGame',
    inputNames: [ '_betId', 'freshHouseSeed', 'rollResult', '_gameOutcome' ],
    inputTypes: [ 'uint256', 'address', 'uint8', 'uint8' ],
    decodedInput: { 
        '0': BigNumber { _hex: '0x265aa6' },
        '1': '0x8F476d1155E9910A885Cae1c4396BDD392c3883E',
        '2': 11,
        '3': 1,
        _length: 4 
    } 
}

Decode Output:

Decode function outputs by passing transaction id.

async function decodeTxOutput(txId){
    const decodedOutput = await decoder.decodeResultById(txId);
    return decodedOutput;
}

decodeTxOutput("0c739761b34a891b3bbecd528302de827736660d76c62dacf8d3a9ebe7dade08");

Output:

{ 
    methodName: 'submitTheGame',
    outputNames: [ null, null ],
    outputTypes: [ 'uint256', 'uint256' ],
    decodedOutput: { 
        '0': BigNumber { _hex: '0x265aa6' },
        '1': BigNumber { _hex: '0x0615ec20' },
        _length: 2 
    }
}

Decode Revert Message (if any):

Decode function outputs by passing transaction id.

async function decodeRevertMessage(txId){
    const decodedMessage = await decoder.decodeRevertMessage(txId);
    return decodedMessage;
}

decodeRevertMessage("5d6db71f3316a2abdf7f08f97cd42880209ee7344816d404ce865a8679bdb7ae");

Output:

{ 
    txStatus: 'REVERT',
    revertMessage: 'Plot is not currently owned' 
}
