4. Verify syntax

1] Check spelling mistakes

It is the very first thing you need to check when you get the Field browser doesn’t contain a valid alias configuration error while compiling your code in the Webpack. No matter which language you use, if you make a tiny spelling mistake, it won’t work, and this is how it works. Even if you try to save the changes by entering the export default config, you need to enter the correct command. Otherwise, you will come across the error, as said earlier.

2] Verify the import path

In most cases, users encountered this error while importing. As you are importing, entering the correct path is the only requirement. Also, you must use the correct command as well. Apart from that, it is required to enter ./ before the path. That said, if you enter the import command like this:

import DoISuportIt from 'path'

it won’t work. The command to the right looks like this:

import DoISuportIt from './path'

That being said, this solution is equally important as the first one. Any typing mistake would cause an invalid alias configuration error for sure.

3] Find error in aliases

Writing the entire web application in one file is not practical and next to impossible. That is why people use aliases. If you are new to this, you must know that aliases work like interlinks. When you use an alias, you need to make sure that the alias is already present in the configuration file. For example, if you want to use a JS module in your present script, you must ensure that the JS module is already there. If you think of creating it later with the same name, you cannot compile the current code without getting the aforementioned error.

4] Verify syntax

At times, using the correct syntax becomes very essential. That is why you must verify the syntax you have used or you are going to use in your code. Even a case of a letter could cause the above-mentioned error. That said, if a case is in the capital, you must use the same across your script and vice versa.

How to fix Module not found error in Webpack?

To fix the Module not found error in Webpack, you need to verify the module path. It appears when you import a module using the import command.

How to fix no extension error in Webpack?

That’s all! Hope this guide helped you.
