#368 — December 10, 2020 | Read on the Web | An Introduction to Event Loop Utilization — Trevor Norris of the core Node.js team has put together a neat writeup of what he’s discovered by measuring and tracking what the event loop is doing. Gets very technical fast, but you might enjoy this brief trip to a fundamental piece of the Node runtime. Trevor Norris | Node v15.4.0 (Current) Released — Nothing huge here, but child_process now supports abort signals, as do readable streams, the main ICU (Unicode) dependency has been updated, and there’s a “very experimental and definitely not finished” BroadcastChannel implementation for worker threads (based upon the Web feature of the same name). Danielle Adams (Node.js Project) | Build Code and Ship In App Messaging in a Few Hours — Stream makes it easy with SDKs and Chat React UI Components. Stream powers Feeds and Chat for over one billion end-users. Stream sponsor | How to Handle Request Validation in Your Express API — “You know it’s important, but it’s difficult to pick a validation library, and if you start writing your own custom validation it can quickly start to feel very messy..” Simon Plenderleith | npm v7.1.0 Released with Two Small New Features — Two new small but sweet features. We get a new command – npm set-script – which lets you create a task in the scripts section of package.json . npm exec now also triggers an interactive subshell for running installed binaries (in the same way npm run scripts can). The npm Blog | Serverless Node.js You Can Run Anywhere — You may have heard of AWS Lambda or Azure Functions, but OpenFaaS is an interesting open source functions-as-a-service platform you can deploy to your own machines. Here’s how you can use Node with it (and not just functions but Express apps too). Alex Ellis | Automatically Generating Social Share Images Serverlessly — This is a perfect use case for a serverless function (on Netlify Functions this time) and a great example of post that pulls together a variety of ideas for a creative end result. Ryan Filler | Puppeteer vs Selenium vs Playwright, A Browser Automation Speed Comparison — Spoiler: There are differences in microbenchmarks but in real world scenarios it’s basically a wash. Use whichever suits your use case. Giovanni Rago (Checkly) | 10 React Security Best Practices — A checklist to help you and your team find and fix security issues in your React applications. Snyk sponsor | How to Make Your Code Reviewer 'Fall in Love with You' — Not Node specific and the title is a little.. cute(?) but there's plenty of useful insights and ideas in here that I think you'll enjoy it, particularly if you want 'plays well with others' on your next report card 😁 Michael Lynch | What's New in Mongoose 5.11: Custom Casting for Paths Valeri Karpov | 10 git Aliases for a Faster Workflow Royee Shemesh (Snyk) | How to Use Docker with Node, A Step-by-Step Tutorial Geshan Manandhar | Nodesource Brings arm64 Support to its Node Binary Distributions — If you want Node in a package to run on aarch64 with CentOS, RHEL, Fedora, Amazon Linux or CloudLinux, NodeSource has what you need. Liz Parody (NodeSource) | cfonts: Striking Text Banners for the Terminal — If you want to catch everyone’s attention when they install your npm package (please don’t..) this might fit the bill ;-) Dominik Wilkowski | htmlparser2 6.0.0: A Forgiving HTML and XML Parser — Consumes documents and calls callbacks, but it can generate a DOM as well. There’s a live demo here.
