I'm trying to get familiar with react and web development. And made my first steps.
Right now I'm using react with react-bootstrap & css modules.
In the main.html I had to include the bootstrap.css file.
I would like to replace my searchbar with react-autosuggest
It seems like bootstrap is breaking the style of react-autosuggest. Is it possible to combine both? Or is it a bad practice?
That is my code where I tried to use both searchbars:
import React, {Component} from 'react';
import styles from './App.css';
import Search from "./Search/Search"
import SearchAuto from "./SearchAuto/SearchAuto"
class App extends Component {
render() {
return (
<div>
<div className={styles.App}>
<h1>Title</h1>
<Search onSearch={this.searchForAddress}/>
</div>
<SearchAuto onSearch={this.searchForAddress}/>
</div>
);
}
}
export default App;
Any help would be greatly appreciated!

I am using React create app and I understand how to import a component into my main app which is called app.js.
What I do not understand is how I import a component in a component which is then imported in app.js (nested component).
In my app.js file, I have a component called Portfolio. In my portfolio.js file, I have a component called Language. Is it even possible to nest components with React create app? Because it does not seem to work.
This is what I tried to do:
In my app.js file :
import React from "react";
import logo from "./logo.svg";
import "./App.css";
import Portfolio from './components/portfolio';
import "./css/styles.css"
function App() {
return (
<div className="App">
<header>
<h1>My beautiful title</h1>
</header>
<Portfolio />
</div>
);
}
export default App;
In my portfolio.js file :
import React, {Component} from 'react';
import Language from './components/language';
class Portfolio extends Component {
render() {
return (
<div className="portfolio">
<Language/>
<h1>My protfolio</h1>
</div>
);
}
}
export default Portfolio;
And in language.js I have:
import React, {Component} from 'react';
class Language extends Component {
render() {
return(
<div>Switch language</div>
);
}
}
export default Language;
In my browser, I keep getting the following error:
"./src/components/portfolio.js Module not found: Can't resolve
'./components/language' in
'C:\Users\mluce\exercice-react\src\components'"
My language.js file is definitely sitting in my components folder. I do not understand why I get this error?
In portfolio.js:
import Language from './language';
I'm quite new to React and after trying for some long hours I haven't been able to add a component inside the main app js
I created my boilerplate with create-react-app
In the main app.js I have:
import React, {Component} from 'react';
// import logo from './logo.svg';
import casa_mini from './casa_mini';
import './App.css';
class App extends Component {
render() {
return (<casa_mini></casa_mini> );
}
}
export default App;
And in the casa_mini.js I have:
import React, {Component} from 'react';
class casa_mini extends Component {
render() {
return (
<div className="listing-box">
<div className="listing-box-image" style={{backgroundImage: 'url("assets/img/casa1.jpg")'}}>
</div>
</div>
);
}
}
export default casa_mini;
Why its not rendering anything? the HTML of casa_mini doesn't appear.. blank page.. Thanks for the help!
Thanks for some fast answers.. the problem is the capital letter of the component..
index.js: Warning: The tag <casa_mini> is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter.
It should be capitalized!
I'm trying to use this css style to styling my react app. But the css didn't work in my element, how to solve it ?
import React, { Component } from 'react';
import style from './styles/css/bootstrap.css';
class App extends Component {
render() {
return (
<div>
<button className={style['btn', 'btn-primary']}>test button</button>
</div>
);
}
}
export default App;
import style from './styles/css/bootstrap.css';
What are you expecting the import to do? If it is to just include the css, then you don't need to give it a name.
import './styles/css/bootstrap.css';
Should be enough.
style['btn', 'btn-primary']
Styling in react comes in various flavours. I would recommend reading the official documentation for it. Assuming you just want to use the classes: btn and btn-primary, you can just pass them to react as:
<button className="btn btn-primary">test button</button>
I put the spinner on the page and I see nothing at all. There are no console of errors or anything like that.
Here is my code:
import React, { Component } from 'react';
import { Spin } from 'antd';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<Spin />
</div>
);
}
}
export default App;
The accepted answer imports all of the library styles.
Here's a preferred way to do so
import Spin from 'antd/es/spin';
import 'antd/es/spin/style/css';
I believe you have forgotten to import the CSS for AndD.
#import '~antd/dist/antd.css';
https://ant.design/docs/react/use-with-create-react-app
The proposed solution by #HalfWebDev doesn't explain that why one should import the CSS at the component level.
Probably this is the reason Remove global Styles
But I would like to add that the proposed solution by #HalfWebDev still doesn't work. Which is to import the component level CSS only like this
import 'antd/es/spin/style/css';
The above CSS still continues adding some global styles and disturbs my styling.
Instead importing the CSS with this method worked for me
import 'antd/lib/spin/style/index.css';
I'm playing around with React and ES6 using babel and webpack. I want to build several components in different files, import in a single file and bundle them up with webpack
Let's say I have a few components like this:
my-navbar.jsx
import React from 'react';
import Navbar from 'react-bootstrap/lib/Navbar';
export class MyNavbar extends React.Component {
render(){
return (
<Navbar className="navbar-dark" fluid>
...
</Navbar>
);
}
}
main-page.jsx
import React from 'react';
import ReactDOM from 'react-dom';
import MyNavbar from './comp/my-navbar.jsx';
export class MyPage extends React.Component{
render(){
return(
<MyNavbar />
...
);
}
}
ReactDOM.render(
<MyPage />,
document.getElementById('container')
);
Using webpack and following their tutorial, I have main.js:
import MyPage from './main-page.jsx';
After building the project and running it, I get the following error in my browser console:
Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. Check the render method of `MyPage`.
What am I doing wrong? How can I properly import and export my components?
Try defaulting the exports in your components:
import React from 'react';
import Navbar from 'react-bootstrap/lib/Navbar';
export default class MyNavbar extends React.Component {
render(){
return (
<Navbar className="navbar-dark" fluid>
...
</Navbar>
);
}
}
by using default you express that's going to be member in that module which would be imported if no specific member name is provided. You could also express you want to import the specific member called MyNavbar by doing so: import {MyNavbar} from './comp/my-navbar.jsx'; in this case, no default is needed
Wrapping components with braces if no default exports:
import {MyNavbar} from './comp/my-navbar.jsx';
or import multiple components from single module file
import {MyNavbar1, MyNavbar2} from './module';
To export a single component in ES6, you can use export default as follows:
class MyClass extends Component {
...
}
export default MyClass;
And now you use the following syntax to import that module:
import MyClass from './MyClass.react'
If you are looking to export multiple components from a single file the declaration would look something like this:
export class MyClass1 extends Component {
...
}
export class MyClass2 extends Component {
...
}
And now you can use the following syntax to import those files:
import {MyClass1, MyClass2} from './MyClass.react'
MDN has really nice documentation for all the new ways to import and export modules is ES 6 Import-MDN . A brief description of it in regards to your question you could've either:
Declared the component you were exporting as the 'default' component that this module was exporting:
export default class MyNavbar extends React.Component { , and so when Importing your 'MyNavbar' you DON'T have to put curly braces around it : import MyNavbar from './comp/my-navbar.jsx';.
Not putting curly braces around an import though is telling the document that this component was declared as an 'export default'. If it wasn't you'll get an error (as you did).
If you didn't want to declare your 'MyNavbar' as a default export when exporting it : export class MyNavbar extends React.Component { , then you would have to wrap your import of 'MyNavbar in curly braces:
import {MyNavbar} from './comp/my-navbar.jsx';
I think that since you only had one component in your './comp/my-navbar.jsx' file it's cool to make it the default export. If you'd had more components like MyNavbar1, MyNavbar2, MyNavbar3 then I wouldn't make either or them a default and to import selected components of a module when the module hasn't declared any one thing a default you can use: import {foo, bar} from "my-module"; where foo and bar are multiple members of your module.
Definitely read the MDN doc it has good examples for the syntax. Hopefully this helps with a little more of an explanation for anyone that's looking to toy with ES 6 and component import/exports in React.
I Hope this is Helpfull
Step 1: App.js is (main module) import the Login Module
import React, { Component } from 'react';
import './App.css';
import Login from './login/login';
class App extends Component {
render() {
return (
<Login />
);
}
}
export default App;
Step 2: Create Login Folder and create login.js file and customize your needs it automatically render to App.js Example Login.js
import React, { Component } from 'react';
import '../login/login.css';
class Login extends Component {
render() {
return (
<div className="App">
<header className="App-header">
<h1 className="App-title">Welcome to React</h1>
</header>
<p className="App-intro">
To get started, edit <code>src/App.js</code> and save to reload.
</p>
</div>
);
}
}
export default Login;
There are two different ways of importing components in react and the recommended way is component way
Library way(not recommended)
Component way(recommended)
PFB detail explanation
Library way of importing
import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';
This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.
Component way of importing
One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:
import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';
This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.
If you are not using lot of components then it should reduce considerably the size of your bundled file.
