![]() ![]() This means you can now have a more personalized debugging experience and identify and fix bugs in your code more efficiently. We termed it the new and improved Debug Pro API. We've heard your requests to incorporate JS into the Debug API, and we're thrilled to announce that we now support the customization of Debug API with JS. ![]() Thanks to its versatility, it's also a go-to choice for building robust web applications. NodeReal aims to solve this problem by providing the Debug Pro API package.ĭo you know that JavaScript (JS) is one of the most popular programming languages in the world? It's well-known for creating dynamic and interactive web pages that bring life to the internet. This has become a pain point for developers who want to hand over the infrastructure to the service providers and focus on the business logic. As debug APIs are computing intensive, most of the service providers will not allow custom tracer to be executed because it may take most of the computing resource and impact other users. As a public infrastructure provider, NodeReal aims to provide the best service to web3 developers, including the debug API. Server.Debug tracer APIs give developers the insight of the code execution on the EVM, allow developers to debug, inspect and set certain debug flag during the execution. Synchronously get user from session, maybe jwt token All experiments here are made with Node.js v0.12.7, which has been compiled against V8 v3.28.71.19. To experience node-inspector in action, we will write a simple Node.js application using restify and put a little source of memory leak within it. However, Heroku is not the only hosting platform. Unfortunately, you will not be able to connect to production applications that are running on Heroku, because it does not allow signals to be sent to running processes. Node-inspectorĮven a more useful alternative to heapdump, because it allows you to connect to a running application, take heap dump and even debug and recompile it on the fly. Great tool which allows Node.js developers to take heap snapshot and inspect them later with Chrome Developer Tools. This module is useful because it can emit leak events if it sees the heap grow over 5 consecutive garbage collections. However you can easily find newer versions of it in GitHub’s fork list for the repository. The original package was abandoned a long time ago and is no longer maintained. If you search for “how to find leak in node” the first tool you’d probably find is memwatch. Node.js Memory Leak Debugging Arsenal Memwatch Therefore my dream of having two application instances per 1X Heroku Dyno vanished. During peak load a new application instance could consume up to 270MB of RAM. Sounds like a very lightweight stack, right? Not quite. Overhead becomes very pricey when you need to serve many requests.įor the new API we chose restify with native MongoDB driver and Kue for background jobs. ![]() The original application occupied almost 600MB of RAM and therefore we decided to take the hot API endpoints and reimplement them. ![]() The application, an API server, was intended to be able to process hundreds of thousands of requests every minute. Recently I was asked to work on a Node.js application for one of my Toptal clients to fix a memory leak issue. ![]()
