Loading CSS using Webpack and React

Question

I am building an app which uses client-server comunications and server-google cloud platform comunications by using socket.io. For the front-end part I'm using React where I have two components App and Touch. In the future I'll change project structures but rigth now it looks like this

My project structure is the following one:

nodemodulesFolder
publicFolder
  jsFolder
     client.js
     socket.io.js
     socket.io.js
     socket.io.js.map
     touch.js
  viewFolder
     App.js
     index.css
     Touch.js
  index.js
  routes.js
.dockerignore
.env
.gitignore
deployment.yaml
Dockerfile
index.js
ingress.yaml
Jenkinsfike
package.json
package-lock.json
server.js
webpack.config.js

My CSS file looks like this:

body { 
    font-family: sans-serif;
}



p {
    color: black;
}

a {
    font-weight: bold;
    text-decoration: none;
    color: #2a2a2a;
}

a:visited {
    font-weight: normal;
}

a:hover {
    text-decoration: underline;
}


.wrapper {
    width: 90vw;
    padding-top: 100px;
    margin: auto;
    width: 50%;
    margin-bottom: 160px;
}

.greyText {
    opacity: 0.4;
}

.buttonWrapper{
    margin: auto;
    position: fixed;
    bottom: 0;
    left: 0;
    right: 0;
    height: 140px;
    overflow: hidden;
    display: flex;
    align-items: center;
    justify-content: center;
    background: #fff;
    border-top: 2px solid #ddd;
}

#ResultText {
    width: 80vw;
    margin-bottom: 100%;
    overflow: auto;
}

#ResultText span {
    display: inline-block;
    margin-top: 10px;
}

#sessionSpeechData {
    width: 80vw;
}

#sessionSpeechData span {
    display: inline-block;
    margin-top: 10px;
}

.nl-Adjective {
    background-color: #1ada47;
    padding: 3px;
    border-radius: 5px;

    background-color: #ff1616;
    padding: 3px;
    border-radius: 5px;
}


.hiddenForms {
    opacity: 0.2;
}

h1 {
    color: black;
}

Hi Joe, could you please post the contents of your webpack.config.js file? — mehmetseckin

You also need style-loader

Install style-loader first

npm install style-loader --save-dev

Webpack 3 version

  { test: /\.css$/,
    use:[ {loader: 'style-loader!css-loader'} ]
  }

webpack 4 version

  {
     test: /\.css$/,
     loader: "style-loader!css-loader"
  }

Joe Over a year ago

After installing style-loader and changing the webpack with the code you provide, do I need to change the components?

Joe Over a year ago

That's what I think I'm still getting the same error.

Hemadri Dasari Over a year ago

Have you restarted your react app after adding the config?

Joe Over a year ago

Yes, I've started again.

Show content of webpack.config.js. It seems you're missing css/style loaders. THIS should help you set it up properly.

{
   module: {
     rules: [
       {
         test: /\.css$/,
         use: [
           { loader: "style-loader" },
           { loader: "css-loader" }
         ]
       }
    ]
  }
}
