I've tried to lower less-loader to version 5.0.0, but it still doesn't work.

Set math as always in your less options
math: 'always'
In your craco.config.js
const CracoLessPlugin = require('craco-less');
module.exports = {
plugins: [

plugin: CracoLessPlugin,

React build is very different from development

Thanks you want to try to help me!
When I build my React web app it looks very different from the development mode. I use serve -s build to watch when the app is build. But also on my online Digitalocean server, it won't look the same as in development. So it probably has something to do with React or how it was build.
This is in development mode:
This is when it is build:
So it looks CSS or Javacript did not compile correctly.
This is my package.json

I Hope someone can help me with this. Thanks for all help!

you should add a .env file in your root and add:
REACT_APP_SC_DISABLE_SPEEDY=true
The Styled Components library uses something called the "Speedy mode" to inject styles on production. you can Google it for more info

React App stuck on Starting The Development Server on Digital Ocean

I have tried running the install command before build, but that did not work either.

await function failing, is a babel compile thing missing?

I've just taken over a project from a disgruntled developer who thinks he's the best thing since sliced bread.
The error
He swears his code was running on the last commit... although, I get problems in an async/await. I vaguely remember having similar problems when not supporting the right version of babel, but that was years back. The project is created with create-react-app.

You are passing a promise to the function, and promise is not a function. You should do instead: await f and not execute it by await f() since the promise just needs to be called and not to be executed.

Create-react-app: Invalid unicode escape in identifier on Safari iOS10

I am having trouble getting a create-react-app 3.4.1 build running on iOS 10 safari. It runs fine in development (npm run), but after building it, accessing the site throws the following error in the console : SyntaxError: Invalid unicode escape in identifier: '\u2160'. (bitwise or character)
This is triggered on this line in one of the chunk.js bundles created during build:
(this.webpackJsonpappname = this.webpackJsonpappname || []).push([[2], [function(e, t, r) {

Any ideas how what the issue could be?
