Project Description:

We are looking for an experienced JavaScript developer with expertise in frontend and backend development, particularly in the area of user behavior tracking and reliable data transmission.

Prerequisites:

Our team has developed JavaScript code that tracks user actions on our webpage and sends this data to our server using the Fetch API. After receiving a successful response from the server, we redirect the visitor to the next site with the URL parameter success.

Problem:

We are facing an issue where some visitors are correctly redirected, but their data is not stored on our server. This inconsistency suggests that our current client-side approach may not be fully reliable, possibly due to:

Asynchronous execution and synchronization issues.
Cancellation of network requests during page navigation or closure.
Insufficient consideration of browser behavior on different devices.

What We Need:

Code Analysis: Analyze our existing JavaScript code to identify possible reasons for data loss.
Solution Proposal: Provide recommendations to ensure reliable sending and storage of user data on the server before redirection.
Code Optimization: Implement best practices for handling asynchronous operations in JavaScript (e.g., using async/await, proper error handling).
Browser Compatibility: Ensure that the solution works consistently across all major browsers and devices.
Consultation: Advise whether our current approach is optimal or if alternative methods for tracking user data and redirection should be considered.

Required Skills:

High proficiency in JavaScript (ES6+), including async/await and Promises.
Experience with Fetch API and handling HTTP requests.
Knowledge of browser behavior regarding network requests during navigation or page closure.
Expertise in client-server communication and handling asynchronous operations.
Familiarity with optimization methods on both frontend and backend.

We will provide the complete JavaScript code for your analysis after agreement; please specify your hourly rate.

Good day. I have almost 2 years of experience as a node.js backend developer. I am ready to provide consultation, as having familiarized myself with your needs, I practically know 100% what the problem is, but of course, I will provide more comments after reviewing the code.
