How to Find, Fix, and Prevent Node.js Memory Leaks

When your application starts to grow, one of the essential factors to consider while scaling is memory management. Poor memory management leads to memory leaks, thus affecting application performance. When the performance degrades, it will directly affect the business. So, it is essential to look out for and fix memory leaks in time. This blog post will look at what memory leaks are and how to avoid them in Node.js applications. Feel free to navigate the post using these links.

Best Practices to Monitor Node.js Performance

Built on the V8 JavaScript engine of Chrome, Node.js is a very lightweight, open-source framework with minimum modules. And since it is an asynchronous system by default, it is faster than most other frameworks. DevOps still need Node.js monitoring to ensure performance better than other frameworks. In order to understand how relevant Node.js still is, note that PayPal, Reddit, LinkedIn, Amazon, Netflix and other high-use, high-visibility service providers use the framework.

Automated testing for NestJS GraphQL projects

NestJS is fast becoming the de facto framework for NodeJS projects. Unlike older frameworks, NestJS was built with TypeScript, which has become commonplace in the JavaScript community. Frameworks like NestJS seem to be preferred by teams that adopt TypeScript. NestJS supports building APIs in REST and GraphQL. The goal of this tutorial is to show how you can add unit and integration tests to a NestJS GraphQL project and automate the testing process with CircleCI.

Store and retrieve static assets on AWS S3 with NodeJS on FlashDrive

AWS S3 is a cloud storage service that saves data as an object associated with a key. Objects are like files and keys are like filenames. Objects are stored in a bucket. We will be auto-generating our object keys while uploading. In a free tier account, you get 5GB of free cloud storage with AWS S3. Note: This tutorial is made for AWS S3 but works as well with S3 compatible providers like Wasabi.com

Continuous deployment of Node apps to Heroku

CircleCI orbs are reusable packages of YAML configuration that condense repeated pieces of config into a single line of code. Since its launch in 2018, the CircleCI orbs registry has been used by developers, development teams, and by companies who want to help developers integrate their services seamlessly into continuous integration pipelines. In this tutorial, we will show how to use CircleCI orbs to continuously deploy a Node.js application to Heroku, one of the most popular hosting platforms.

How to deploy a Node.js application to AWS Lambda using Serverless Framework

Being a developer is awesome. Writing code, solving problems, and thinking of ingenious solutions for complicated algorithms is what we live for. But, the grass is not always so green on this side of the fence. Sooner or later, you need to get your hands dirty and deploy the app you worked so hard on. Deployments are not always easy. To be blunt, they can be challenging and time-consuming. That’s what we’ll solve in this tutorial.

Improved Error Tracking for Node.js in AppSignal

Good news for Node.js developers using AppSignal: a new version of our Node.js library is available on npm with improved error tracking. We’ve added two new helpers to make your life easier as a Node.js developer. One helper allows you to track errors whenever you need to, no matter how many nested spans you have in your current context. The other lets you send an isolated error with no spans or context involved (for more information about spans, check out our docs).

Node.js Performance Monitoring

Software developers use the Node.js environment to develop robust and innovative applications. But the bigger the goal, the higher the risk. Learn about Node.js performance monitoring to ensure quality and risk-free software products. Part of diligent software development is making sure all system applications work well individually and as a whole.
