create-react-app

问题 I recently created a website with create-react-app. Since this is not a web app, why do I need a server to see it? I tried to open the index file in build folder but it doesn't work unless I'm serving it from a server. 回答1: You can set the homepage root url in the package.json file e.g. { ..., "homepage":"file:///<path to build directory" } npm run build This will now find the static content in the build directory from the file system without a server. 来源： https://stackoverflow.com/questions

问题 I have a React todo app I built using create-react-app and I built a simple express server to query mongoDB to get all the appointment objects. It works just as expected when I am running it on my machine. The front end spins up on localhost:3000 and the server on localhost:3001 . I use axios to make a get request to localhost:3000/api/appointments to load all the appointments into the App.js state. I uploaded it to Heroku and I got a CORS error on the request. After that, I tried to just use

问题 I'm struggling with following "error" in VSCode : Argument for '--jsx' option must be: 'preserve', 'react-native', 'react' Hence, react-scripts (create-react-app) automatically sets the jsx key to react-jsx value, when react value seems to work. Actually, the code works perfectly and displays the page I want, but the IDE is underlining kinda everything as errors, saying : Cannot use JSX unless the '--jsx' flag is provided. Here is my tsconfig.json : { "compilerOptions": { "target": "es5",

问题 I have Linux with node - 12.4.0, npm - 6.9.0, npx - 6.9.0. I ran command npx create-react-app cra And getting following result: Installing packages. This might take a couple of minutes. Installing react, react-dom, and react-scripts... npm ERR! Maximum call stack size exceeded Aborting installation. npm install --save --save-exact --loglevel error react react-dom react-scripts has failed.

问题 So I am trying to create a new React project using npx create-react-project but it keeps getting stuck after downloading the packages. So far the folder only contains the node modules and the 2 package.json files. The create-react-app goes well until it reaches found 0 vulnerabilities. I have done this in different folders and different hard drives but the same result. It just doesn't go further. I also deleted my previous global create-react-app installation but this didn't make a difference
