Angular application with Material Design integration

I've been struggling to implement material design into my angular app, but I'm facing some challenges.

After installing material design and adding all the necessary modules to the app.moduel.ts file, the components are not displaying correctly.

An error message pops up saying:

Could not find Angular Material core theme. Most Material components may not work as expected. For more info refer to the theming guide:
https://material.angular.io/guide/theming

I also added the theme link to the head section of the index.html file

<link href="node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

However, I am getting a Status Code:404 Not Found for some reason. I attempted to move the css files to the assets folder, but that didn't solve the issue.

It's peculiar because the sample app for material design on github does not include a link to any theme css file.

https://github.com/jelbourn/material2-app/blob/master/src/index.html

http://localhost:4200/node_modules/@angular/material/prebuilt-themes/indigo-pink.css

Here is how my index.html file appears:

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>M2App</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
  <link href="node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

</head>
<body>
  <app-root>Loading...</app-root>
</body>
</html>

Answer №1

Depending on the structure and configuration of your app, the Status Code:404 Not Found error may be due to the relative path from index.html to

"node_modules/@angular/material/prebuilt-themes/indigo-pink.css"
not being found. Adding some ../../ to the path could resolve this issue.

For more information, you can refer to the theming guide documentation:

Alternatively, you can directly reference the file like this:

<link href="node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

The exact path will vary depending on your server setup.
