6 Tools for Debugging React Native

Debugging is an essential part of software development. It’s through debugging that we know what’s wrong and what’s right, what works and what doesn’t. Debugging provides the opportunity to assess our code and fix problems before they’re pushed to production.

In the React Native world, debugging may be done in different ways and with different tools, since React Native is composed of different environments (iOS and Android), which means there’s an assortment of problems and a variety of tools needed for debugging.

Thanks to the large number of contributors to the React Native ecosystem, many debugging tools are available. In this brief guide, we’ll explore the most commonly used of them, starting with the Developer Menu.

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. — Brian W. Kernighan

The Developer Menu

The in-app developer menu is your first gate for debugging React Native, it has many options which we can use to do different things. Let’s break down each option.

  • Reload: reloads the app
  • Debug JS Remotely: opens a channel to a JavaScript debugger
  • Enable Live Reload: makes the app reload automatically on clicking Save
  • Enable Hot Reloading: watches for changes accrued in a changed file
  • Toggle Inspector: toggles an inspector interface, which allows us to inspect any UI element on the screen and its properties, and presents and interface that has other tabs like networking, which shows us the HTTP calls, and a tab for performance.

In this guide, you’ll learn how to take advantage of Visual Studio Code to supercharge your development workflow. This article is written for beginners who may be using Visual Studio Code for the first time. VS Code, as it’s commonly known, is considered a "lightweight" code editor. In comparison with full integrated development environment (IDE) editors which occupy gigabytes of disk space, VS Code only uses less than 200MB when installed. Despite the "lightweight" term, VS Code offers a massive number of features which keep increasing and improving with every new update. For this guide, we'll cover the most popularly used features. Every programmer has their own tool set which they keep updating whenever new workflows are discovered. If you want to learn every tool and feature VS Code has to offer, check out their official documentation . In addition, you may want to keep track of updates for new and improved features.

6+ Best Websites for Free Fonts in 2020

I firmly believe that, in order to strike the optimal balance between minimalism and visual appeal, a user interface should display no more than what’s absolutely necessary while making those necessary elements look visually appealing. Keep it simple, but make the simple look amazing. But, what does simple look like exactly? Well, strip away all of the over-the-top marketing gimmicks, redundant features, and cluttering visuals, and most of what’s left is the UI copy and text content. As boring as this sounds, let’s be honest: this is the most important aspect of any app or website. Information and the ability to navigate it is the entire reason users are using our app or website. So with the right typeface coupled with the right font styles (see “ Font vs typeface: the ultimate guide ”), we can create designs that are quite simple and yet visually appealing at the same time. This emphasizes the most important aspects of the design while usin

If you think of the ideas of open source applied to information in an encyclopedia, you get to Wikipedia – lots and lots of small contributions that bubble up to something that’s meaningful. – Matt Mullenweg One of my favorite aspects of open source is the fact that anyone can contribute! It’s like “productive volunteering” (if you’ll humor me). It’s a fantastic way to build something bigger than you, give back to the community, and level up your skills. In this article, we’re going to talk about practical ways for you to get involved in open source TypeScript projects. We’ll first cover assessing your level then jump into how you can find opportunities. Assessing Your Level Before you get started contributing to open source, you want to find your comfort level. Where are you at skill-wise? What level of complexity are you wanting to solve? How much time do you want to spend? These are important questions to consider before diving in. This
