Preface​

React Native, as a cross-platform framework, has one of the most headache-inducing problems: version updates. Especially when encountering major version updates, the configuration and build files for JavaScript, iOS, and Android all undergo significant changes. Sometimes these configuration files are coupled together, where one change affects everything.

This article assumes that the person leading the React Native upgrade is a frontend developer who is familiar with JavaScript-based frontend build processes. If conditions permit, it's strongly recommended to involve iOS and Android developers during the upgrade. For some trivial upgrade details, face-to-face communication is far more efficient than search engines.

This article is translated from Lydia Hallie's ✋🏼🔥 CS Visualized: CORS. She used many animations to explain the concept of CORS. Since no one has translated this article in China yet, I've translated and corrected some errors based on my understanding of the original text, hoping to help everyone.

The HTTP protocol is arguably the most familiar network protocol for developers. Its characteristics of being "simple and easy to understand" and "easy to extend" have made it the most widely used application-layer protocol.

Despite its many advantages, the protocol specification contains numerous hidden pitfalls due to various compromises and limitations during its definition, which can easily trap unsuspecting developers. This article summarizes common pitfalls in HTTP specifications to help developers consciously avoid them and improve their development experience.

Talking about React Native in 2020, in the ever-changing frontend circle, might be considered quite alternative. Before writing this article, I hesitated, but then I thought that writing technical articles isn't about following trends - writing about whatever is trendy. So I decided to write this React Native performance optimization article.

The React Native performance optimizations discussed in this article haven't reached the level of modifying React Native source code, so they are highly universal and useful for most RN developers.

If you've read some webpack4 optimization articles, you'll definitely encounter DLL dynamic link libraries. They are remembered by many beginners for their complex configuration. Today, I'll explore webpack DLL configuration step by step from a learner's perspective and finally arrive at a perfect solution.

The content and viewpoints in this article are different from most webpack4 optimization articles. If you have different opinions, welcome to discuss with me in the comments section.

Today I'm mainly sharing some confusing knowledge points in webpack, which are also common interview topics. I've summarized content scattered across documentation and tutorials, which appears to be unique on the entire internet. You can bookmark this for easy reference and learning later.

To improve push notification delivery rates, the product team proposed a requirement: display a small tip when app push notifications are disabled, and clicking the tip should jump to the app's notification settings interface.

Our app is built with React Native, and Facebook doesn't officially provide these features, so we need to develop corresponding native modules.
