im little bit React noobie when it comes to project setup. I have created a simple project with defaults using npx create-react-app. I wanted to use Sass so I installed a sass module. When it comes to usage, I created styles.scss with basic background styling, and tried:
function App() {
return \<div className="container"\>app\</div\>;
}
export default App;
this works fine, but I wanted to use it this way:
import styles from "./styles.scss";
function App() {
return <div className={styles.container}>app</div\>;
}
export default App;
but it doesn't work. I see that any className is given to this div. I quite don't understand why. Could anybody explain me the difference and give any tips how can I start using the second option mentioned?
If you're just trying to import a stylesheet, you should simply use:
import './styles.scss';
Of course you should also have SASS installed in your project, but I assume you already do.

I have created my own react component library using lerna and I have a package that holds multiple icons. I want to provide the possibility to use path imports, to avoid pulling in unused modules.
So I want to use
import PlusIcon from '#my-lib/icon/plus'
instead of
import { PlusIcon } from '#my-lib/icon'
in my react app, without any additional configuration.
I am struggling to find any documentation/tutorial for this, so I don't even know where to start. I would be grateful for any hint.
Thanks in advance!
Your plus file need to have an default export for the PlusIcon.
For instance
function PlusIcon = () => <p>+</p>;
export default PlusIcon;
As long as you have something like that, you can import it as
import PlusIcon from 'path-to-plus-icon
I'm building a react component library (using typescript and styled-components) and I want to reuse as much as possible code between the two targets (web and native).
I have a folder called styled, and inside that folder, I have two index files: index.ts and index.native.ts.
Inside the index.ts I have: export { default as styled } from 'styled-components'; while in the index.native.ts I have export { default as styled } from 'styled-components/native';
I know react-native uses index.native.ts instead index.ts during the build process when it is available but I really need to make the IDE (vscode) to understand that, I mean, when I'm building a Button.native.ts the statement: import { styled } from '../styled' should import from the .native barrel and the ctrl + click should let us to the .native file.
I don't know if there is a configuration to change the default import file used as a barrel, I already tried to search in the typescript documentation for some react-native preset but I didn't find anything.
It is not related to TypeScript, it is an open issue on VSCode GitHub page. Still doesn't have any solution.
Even I didn't find solution on react native vscode plugin.
By my understanding you are working on RNW, so it is not a correct expectation that VSCode understand by Ctrl+CLICK your meaning is Web or Native side.When it works in development and production so forget about opening right code by click.
I'm trying to get Icons working with Gatsby but it they don't seem to be showing in the production build.
I am importing the icons like this
import {
initializeIcons
} from "office-ui-fabric-react"
and calling the function like this
initializeIcons()
which is all in my index.js page file. This works fine when running gatsby develop however when i run gatsby build && gatsby serve the icons show up like this.
However, when I look inside Chrome dev tools, i can see the icon fonts being downloaded.
so i am assuming it is something to do with the static render of gatsby. I started with this template https://github.com/microsoft/gatsby-starter-uifabric
Any help is appreciated.
I had the same issue. After trying a bunch of work-arounds, I ended up using office-ui-fabric-core instead.
Install the library:
npm i office-ui-fabric-core
Import the ui-fabric-core css
import "office-ui-fabric-core/dist/css/fabric.css";
example icon component:
import React from "react";
const MyIcon = ({iconName}) => <i className={`ms-Icon ms-Icon--${iconName}`} aria-hidden="true"></i>
export default MyIcon;
Example usage:
<MyIcon iconName="People" />
The answer was to use the initializeIcons(undefined, { disableWarnings: true }) method outside of the App class code, just above it will do fine.
To quote the wiki article on the use of this method
If your code is running in an environment where icons may have already been registered, you may need to disable the warnings. (By default, registering the same icon twice will ignore subsequent registrations.) To initialize icons and avoid duplication warnings, pass options into initializeIcons:

Well, recently I've started using the React.js library, and now I'm trying to use it with Firebase Hosting, with the TypeScript language. But, every time I try to write some code using tsx it just doesn't work, for example:
import * as React from "react"; //red underline under "react"
import "./App.css";
import logo from "./logo.svg";
class App extends React.Component {
render() {
return <h1>Hello</h1>; //red underline under <h1> and </h1>
}
}
export default App;
that way I just can't write any jsx code here, because it always appears the issue:
test.tsx(1,1): error TS7026: JSX element implicitly has type 'any' because no interface 'JSX.IntrinsicElements' exists
Can somebody please help me with this?
How did you create your react application? If you used create-react-app you'll need to use react-scripts-ts as your --scripts-version flag. This should install the #types packages along side React's dependencies, eliminating your problem.
Also, it should get you started with an App.tsx file as the one provided in your snippet is not a valid typescript react component (i.e. the your render() method is not public).
Happy hacking!
I solved this issue by reloading VSCode.
ctrl+shift+P > Developer: Reload Window
I want to selectively use semantic-ui-css classes in my components. The problem is that I use PostCSS modules option which scopes locally all the class names for a specific component. When I use semantic-ui-react components, for example a button, it renders element button with classes ui button, but the included css gets scoped locally so instead of button i get button-min_ui__14RRq
I need to do one of two things:
Import Semantic-ui css without the classes being scoped locally
Make Semantic-ui components to use classes that are being scoped locally
For now I see that I have only one option:
import React from 'react';
import { Button } from 'semantic-ui-react'
import semantic from 'semantic-ui-css/components/button.min.css'
export default class Test extends React.Component {
render(){
return (
<Button className={[semantic.ui, semantic.button]}>Click Here</Button>
)
}
}
I'm explicitly stating what classes the button is to use. It works, but I have to do that for every element and it keeps the default classes. So I get ui button button-min_ui__14RRq button-min_button__Uio9b
Is there a way of doing this without it keeping the default classes?
I'm not sure I fully understand the question, but will give it a shot. Should you try excluding the semantic/global styles from PostCSS?
eg. If you are using webpack use 'exclude' in the loader definition.
(it's something we do in one of our the projects where I work)

you are having similar problem to me.
Making External Library(Semantic ui React) and CSS module work with webpack css-loader
From my understanding,you want to exclude semantic-ui-react-library styling from css module so that it work with your application. You can create multiple rules for css loader to resolve this.
Take a look at this Using Semantic UI With CSS Modules in Webpack
I always use css of a library not the components they provide, I write my own.
So install only semantic-ui-css. Now import like below in your react application.
import ReactDOM from 'react-dom'
import 'semantic-ui-css/semantic.min.css'
import App from './App'
ReactDOM.render(<App/>, document.getElementById('root'))
