Ethereum: Fastest way to request API with NodeJS

Binance API Request with Node.js and Axios: The Fastest Way

================================================================================

As a developer, you’re probably familiar with the importance of fast response times when interacting with APIs. In this article, we’ll look at how to query the Binance API using Node.js and Axios, paying special attention to optimizing the code for maximum performance.

Binance API Endpoint

—————————-

Before diving into the solution, let’s take a look at the Binance API endpoint we’re working with: This endpoint is used to query the current state of the API and can be useful for detecting changes or errors in your application.


Axios Request
----------------------
To make an HTTP request to the Binance API, you will need to use Axios. Here is a simple example:
const axios = require('axios');
async function pingBinanceAPI() {
try {
const response = await axios.post(
'
{}
);
console.log(response.data);
} catch (error) {
console.error(error);
}
}

In this example, we create an instance of Axios and use its postmethod to send a POST request to the Binance API endpoint. Thedataproperty is set to an empty object that contains no payload.


Optimized for fast response time
---------------------------------------
To optimize our code for a fast response time, we need to consider several factors:

Request Timeout: We want to avoid infinite blocking if the request takes too long.


Processing response data: We must process response data as quickly as possible without unnecessary delays.

Here's an updated example that includes these optimizations:
const axios = require('axios');
async function pingBinanceAPI() {
try {
const startTime = Date.now();
await axios.post(
'
{},
{ timeout: 10000 } // request waiting time in milliseconds
);
const endTime = Date.now();
const responseTime = (endTime - startTime) / 1000; // convert milliseconds to secondsconsole.log(Response time: ${responseTime.toFixed(2)} seconds);
} catch (error) {
console.error(error);
}
}

In this updated example, we've added a timeout’ parameter to the Axios request. If the request takes more than 10 seconds, it will be canceled and an error will be issued. We also log the response time in seconds using the toFixed(2) method.

Additional optimization tips

Use async/await

: Instead of using .then() callbacks to handle errors and responses, use async/await to simplify your code and make it more readable.

Avoid Unnecessary Requests
: If your application does not need to retrieve data immediately, consider caching or buffering the response data until it is needed.

API Performance Monitoring: Use tools like curl or browser developer tools to monitor API performance in real-time. This can help you identify areas for improvement.

By applying these optimizations and taking into account factors such as request latency and response data processing, you can significantly improve the performance of your Binance API requests with Node.js using Axios.
