Solutions to the inaccessibility of react startup: 1. Install "http-proxy-middleware"; 2. Find "setupProxy.js" and delete it directly; 3. Create a new project and restart the project.
The operating environment of this tutorial: Windows 10 system, react18.0.0 version, Dell G3 computer.
What should I do if the react startup cannot be accessed?
The react project startup shows that the local connection has been refused
It’s a very strange problem. I could use it normally the day before, and then opened the computer to start the project the next day A problem occurred.
The solution for react project startup showing that the local connection has been refused was not found on Baidu
You can connect normally by going back to the previous version through the git version
There was really nothing I could do at the beginning, so I continued writing from the previous version.
As a result, there was a version conflict. After I solved it manually, I started the project again.
The local connection was refused again...
I was so angry and numb at the time
I couldn’t find a way to do it anymore, so I had to use stupid methods
to create a new project and make sure that the new project could be started.
Moved the original project files one by one
Finally I successfully found the culprit
This thing is used as a proxy Yes, just delete this thing and you can start it normally, but not vice versa
The problem lies here
There are several ways to write this because of version issues
Put it here The version I can use normally
const { createProxyMiddleware } = require('http-proxy-middleware') module.exports = function (app) { app.use(createProxyMiddleware('/api', { target: 'http://106.14.82.240:3000', secure: false, changeOrigin: true, pathRewrite: { "^/api": "/api" } })) }
Also remember to install http-proxy-middleware

React's one-way data binding ensures that data flows from the parent component to the child component. 1) The data flows to a single, and the changes in the state of the parent component can be passed to the child component, but the child component cannot directly affect the state of the parent component. 2) This method improves the predictability of data flows and simplifies debugging and testing. 3) By using controlled components and context, user interaction and inter-component communication can be handled while maintaining a one-way data stream.

Use Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.

Using incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
