Pretty Print Raw files are usually minified, and therefore hard to read. Use the Pretty Print option to format it In the background, Chrome is creating a new file (names filename.js:formatted), closing that file will undo the formatting. If doing this each time is getting boring, then there's an experimental setting to auto-enable pretty print for all sources. Under ⋮ → Settings → Experiments Sele

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with

Introduction In our previous exploration, we delved into the simplicity of HTTP/0.9, a protocol that served as the web’s initial foundation. However, as the internet evolved, so did its needs. Enter HTTP/1.0, a landmark version released in 1996 that laid the groundwork for the web we know today. HTTP/1.0 was a game-changer, introducing features that revolutionized web communication: Headers: Metad
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

CVE-2024-4367 - Arbitrary JavaScript execution in PDF.js — Codean Labs
This post details CVE-2024-4367, a vulnerability in PDF.js found by Codean Labs. PDF.js is a JavaScript-based PDF viewer maintained by Mozilla. This bug allows an attacker to execute arbitrary JavaScript code as soon as a malicious PDF file is opened. This affects all Firefox users (<126) because PDF.js is used by Firefox to show PDF files, but also seriously impacts many web- and Electron-based a
Today we’re excited to announce the availability of TypeScript 4.7! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. Types help describe what kinds of values you’re working with and what kinds of functions you’re calling. TypeScript can use this information to help you avoid about mistakes like typos, missing arguments, or forgetting

Dynamic Static Typing In TypeScript — Smashing Magazine
In this article, we look at some of the more advanced features of TypeScript, like union types, conditional types, template literal types, and generics. We want to formalize the most dynamic JavaScript behavior in a way that we can catch most bugs before they happen. We apply several learnings from all chapters of TypeScript in 50 Lessons, a book we’ve published here on Smashing Magazine late 2020

ts-blank-space
What is ts-blank-space? ts-blank-space is a fast type-stripping compiler that converts TypeScript to JavaScript. It supports a modern subset of TypeScript by erasing the types and replacing them with whitespace. That's it. It is not a type checker and does not perform any other code transformations. The underlying technique can improve build performance and simplify development. The implementation
Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

1 Introduction Compilers, assemblers and similar tools generate all the binary code that processors execute. It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code. Often the only practical way to protect all binaries with a particular security hardening method is to have the compiler do it. And, with software security becoming more and

With Converso, you've got end-to-end encryption,
Introduction to Go 1.21 The latest Go release, version 1.21, arrives six months after Go 1.20. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility; in fact, Go 1.21 improves upon that promise. We expect almost all Go programs to continue to compile and run as before. Go 1.21 introduces a small ch
