Ethereum futures application subscription invites Binance to aws lambda and nodejs 12
As a developer, you are likely to feel the importance of seamless integration between the front and background systems. In this article, we are looking at how to connect to the Ethereum futures application in the Binance Application using the aws lambda and nodejs 12 app.
background
The Ethereum Future Application Subscription Provides an Easy -to -use Interface for the Binance Exchange Store Derivatives. The application subscription allows developmenters to make API calls from their front, such as online applications or mobile applications, without having to connect direct connections to binance servers. However, the introduction of the nodes 12 app, directly interacting with the Binance Application interface, can be challenging due to safety and performance concerns.
AWS Lambda Setting
To solve this problem, we use aws lambda as a background service. This allows us to drive in the cloud of nodes 12 without disclosing sensitive information or Creating Direct Connections to Binance Servers. HERE’S A STEP -Y -STEP GUIDE:
- Create the AWS Lambda Function : Go to the AWS Management Console and Go to the Lambda Coil. Create a New Function with the following Settings:
* Function Title: Binance-Futtures-LMBDA
* Runtime: nodojs 12
* Role: Choose “Custom Role” and create a new role in access to the Binance Application Interface.
- Take code : please use the
lambda.zipfile or aws cld to the lambda application for your nodejs 12 application.
Connecting Binance API
Now that we have a nodes 12 feature, we can connect to the Binance Application interface at the Library, such as axios'. HERE IS AN EXAMPLE OF THE CODE END:
JavaScript
Const axios = demanding ('axios');
Exports.handler = async (event) => {
Try {
Const response = wait axios.post (https: // Binance-dos.github.io/apidocs/ustures/#new-consuision, event);
Console.log (response.data);
} catch (error) {
Console.error (Error);
}
};
`
In this exam, we will serve a post request to the Binance Application subscription to the “New Order of Trade” End Point with A Dap Event Object. The axios library deals with us with authorities and authorization.
to complete the Lambda Function
Complete the Lambda Function Follows these steps:
- Create a new deployment Package : Create a New Zip file containing the nodes 12 Application Code.
- Send A Commissioning Package Lambda : Download The Deployment Package to Lambda With AWS CLD or Console.
- Send Lambda Activity
: Send Lambda to Send an Application Subscription Call from the Interface Service, such as the Online Application.
* troubleshooting econnrefused 127.0.0.1:
If you have a problem with your connection to the Binance Application subscription, you may encounter “EconRefused” Error Code. This may be due to a number of reasons, including:
- Untecutiful DNS Settings or Firewall Rules
- Network Connection Problems
- Invalid Access Information
To solve this problem, make sure that nodes 12 has the right permits and works in the right aws lambda environment.
Conclusion
In this article, we have explored how to connect to the ethereum futures application in the Binance Application using aws lambda and nodejs 12. By installing a safe and performance solution, you can seamlessly integrate your interface with the Binance Application subscription. Be sure to always follow the best practices for safety and performance optimization when building ready -made applications.
