Ethereum Futures API Call on Binance with AWS Lambda and NodeJS 12

As a developer, you are probably familiar with the importance of seamless integration between your frontend and backend systems. In this article, we will explore how to connect to the Ethereum futures API on Binance using AWS Lambda and NodeJS 12.

Background

The Ethereum Futures API provides an easy-to-use interface for trading derivatives on the Binance exchange. The API allows developers to make API calls from their interfaces, such as web applications or mobile applications, without having to establish direct connections to Binance servers. However, implementing a NodeJS 12 application that directly communicates with the Binance API can be challenging due to security and performance issues.

Setting Up AWS Lambda

To solve this problem, we will use AWS Lambda as our backend service. This allows us to run NodeJS 12 in the cloud without exposing sensitive information or establishing direct connections to Binance servers. Here’s a step-by-step guide:

• Create an AWS Lambda Function: Go to the AWS Management Console and navigate to the Lambda Dashboard. Create a new function with the following settings:

* Function name: binance-futures-lambda

* Runtime: NodeJS 12

* Role: Select “Custom Role” and create a new role with permissions to access the Binance API.

• Deploy the code: Deploy your NodeJS 12 application to Lambda using the lambda.zip file or the AWS CLI.

Link to Binance API

Now that we have the NodeJS 12 function set up, we can connect to the Binance API using a library like axios. Here is an example code snippet:

const axios = require('axios');


exports.handler = async (event) => {

  try {

    const response = await axios.post( event);

    console.log(response.data);

  } catch (error) {

    console.error(error);

  }

};

In this example, we send a POST request to the /new-order-tradeendpoint of the Binance API with aneventobject as data. Theaxios' library will handle authentication and authorization for us.

Starting the Lambda function

To run a Lambda function, follow these steps:

• Create a new deployment package

  

  : Create a new ZIP file containing your NodeJS 12 application code.

• Upload Deployment Package to Lambda: Upload the deployment package to Lambda using the AWS CLI or console.

• Run Lambda Function: Run a Lambda function by sending an API call from a front-end service, such as a web application.

Troubleshooting ECONNREFUSED 127.0.0.1:

If you are having trouble connecting to the Binance API, you may encounter ECONNREFUSED error codes. This can be caused by a variety of reasons, including:

• Insecure DNS settings or firewall rules

• Network connectivity issues

• Incorrect credentials

To resolve this issue, make sure your NodeJS 12 function has the correct permissions and is running in the correct AWS Lambda environment.

Conclusion

In this article, we explored how to connect to the Ethereum futures API on Binance using AWS Lambda and NodeJS 12. By implementing a secure and efficient solution, you can seamlessly integrate your front-end application with the Binance API. Remember to always follow best practices for security and performance optimization when building production-ready applications.
