Create React App Officially Deprecated Amid React 19 Compatibility Issues
Create React App is officially deprecated due to React 19 issues and lack of maintenance—developers should switch to Vite or other modern alternatives.
A different style of callbacks experiment written for an answer on Stack Overflow:
It allows you to register callbacks to standard Node functions that expect error-fist callback style, but use a different convention inside of your callback - the first argument to your callback will either be an instance of Error
on failure (with its message
field set to the original error) or the first non-error argument on success.
For code examples see node-errc-example on GitHub.
Install to use in your Node project, updating the dependencies in package.json:
npm install errc --save
var errc = require('errc');
var fs = require('fs');
fs.readFile('example2.txt', errc(function (data) {
// here data is either an instance of Error on failure
// or a real data on success
});
