Hello:
I want to know if I can find how can I call some Node.js script from C#, which call a npm package called ccxt, and return the truncated strings to C#. And one step further, how can I call similar Node.js script and pass some parameter and get the results back to C#.
My OS: Window 10 Pro (version 21H2)
Node.js: version: 19.0.0
CCXT: version: 2.1.33
The following is node.js script:
D:\nodejs\CCXT_Exchanges>type ccxt_all_exchanges.js
'use strict';
const ccxt = require('ccxt');
console.log(ccxt.version);
var all_exchanges = ccxt.exchanges
console.log(all_exchanges)
D:\nodejs\CCXT_Exchanges>
The output for running the node.js script:
D:\nodejs\CCXT_Exchanges>node ccxt_all_exchanges.js
2.1.33

... 20 more items
]
D:\nodejs\CCXT_Exchanges>
The issue here is that console.log only shows the first 100 items, there are 20 more items will be returned. I want to use ClearScript to run the above node.js script and return all 120 items to C#.
How can I do this?
One step further, can I pass variable to async function using CCXT?
D:\nodejs\CCXT_Binance>type Binance1PairOrderBook.js
const ccxt = require('ccxt');
console.log(ccxt.version);
if (process.argv.length != 3)
{
console.error('Usage: BTC/USDT');
console.error('Please try again!');
process.exit(1);
}
const [nodejs, script1, pair1] = process.argv;
let exchange = new ccxt.binance
({
'adjustForTimeDifference': true,
defaultType: 'spot',
'verbose': false
});
const pair1OrderBook = async (pair1) => {
try
{
await exchange.loadMarkets();
const orderbook1 = await exchange.fetchOrderBook(pair1);
if (typeof orderbook1 !== 'undefined')
{
const json_orderbook = JSON.stringify(orderbook1);
console.log(json_orderbook);
}
else
{
const obj_orderbook0 = ({ 'Symbol': pair1, 'Data': [] });
const json_orderbook0 = JSON.stringify(obj_orderbook0);
console.log(json_orderbook0);
}
}
catch (err)
{
console.error(err)
}
};
pair1OrderBook(pair1);
D:\nodejs\CCXT_Binance>
To use this code, call this with one cryptocurrency trading pair, the biggest pair is: BTC/USDT, but the output contains too many rows, so calling it with not very active pairs, like this:
D:\nodejs\CCXT_Binance>node Binance1PairOrderBook.js FXS/USDT
Or some pairs, which do exist, but no trade volume here: ETH/USDC, like the following:
D:\nodejs\CCXT_Binance>node Binance1PairOrderBook.js ETH/USDC
2.1.33

{"symbol":"ETH/USDC","bids":[],"asks":[],"nonce":2090539859}
D:\nodejs\CCXT_Binance>
Please advise on if I can use the repo to do the job: call Node.js from C# WinForms App?
Thanks,
