Webpack can only understand JS and JSON files. Loader helps webpack understand other file types and add them to your application.

• babel-loader: transpile ES2015 code using Babel.
• file-loader: Return the (relative) URL and the file to the output folder.
• html-loader: Export HTML as string, require references to static resources.

As you can see, ts-loader is for we can load typescript files with webpack. The Module is not found: Can’t resolve ‘ts-loader’ error appears may only be when you install the project, which is missing the ts-loader module to compile typescript files in the project.

Because this error can appear when your project is missing the specific package here ts-loader, we can fix it by reinstalling it. You can install this package with either of the following commands depending on whether you are using npm or yarn.

Terminal:

npm install ts-loader

yarn add ts-loader

After running the command, you wait until the program completes, and then you rerun the program with the command “npm start”.

By reloading this library, if your project doesn’t have a package, it will be added for you. If the version is incorrect, it will be replaced with the latest version… If it is still there, you can refer to the method below.

If you have installed the package and still show an error when running the program, you can check your dependencies in the package.json file to see if you have installed the correct version of the library or not. There are some cases when you have installed the library, but the dependencies still need to be corrected with the library version. What should you do?

Code:

"dependencies": {
"react": "^18.2.0",
"react-dom": "^18.2.0",
}
