In simple terms, a Node.js memory leak is an orphan block of memory on the Heap that is no longer used by your app because it has not been released by the garbage collector. It’s a useless block of memory. These blocks can grow over time and lead to your app crashing because it runs out of memory.\n\nVisit the following resources to learn more:", "links": [ { "title": "Memory leaks in Node.js", "url": "https://sematext.com/blog/nodejs-memory-leaks/", "type": "article" }, { "title": "Memory leaks causes", "url": "https://sematext.com/blog/nodejs-memory-leaks/#what-causes-them-common-node-js-memory-leaks", "type": "article" }, { "title": "Memory leaks detectors", "url": "https://sematext.com/blog/nodejs-memory-leaks/#node-js-memory-leak-detectors", "type": "article" }, { "title": "Explore top posts about General Programming", "url": "https://app.daily.dev/tags/general-programming?ref=roadmapsh", "type": "article" } ] }, "DcmGcVlEHL4IV7yPMDpVa": { "title": "node --inspect", "description": "Node.js provides a built-in DevTools-based debugger to allow debugging Node.js applications.\n\nVisit the following resources to learn more:", "links": [ { "title": "Debugging Node.js with Chrome DevTools", "url": "https://medium.com/@paul_irish/debugging-node-js-nightlies-with-chrome-devtools-7c4a1b95ae27", "type": "article" } ] }, "CvkjlOpT34lOHgzQHL40s": { "title": "Using APM", "description": "As much fun as it is to intercept your container requests with inspect and step through your code, you won’t have this option in production. This is why it makes a lot of sense to try and debug your application locally in the same way as you would in production.\n\nIn production, one of your tools would be to login to your remote server to view the console logs, just as you would on local. But this can be a tedious approach. Luckily, there are tools out there that perform what is called log aggregation, such as Stackify.\n\nThese tools send your logs from your running application into a single location. They often come with high-powered search and query utilities so that you can easily parse your logs and visualize them.\n\nVisit the following resources to learn more:", "links": [ { "title": "Debugging using APM", "url": "https://stackify.com/node-js-debugging-tips/", "type": "article" }, { "title": "Explore top posts about APM", "url": "https://app.daily.dev/tags/apm?ref=roadmapsh", "type": "article" } ] }, "SJ01N7vMZkNiIuMYQhdpj": { "title": "Garbage Collection", "description": "Memory management in JavaScript is performed automatically and invisibly to us.
