Valid Alias Configuration

field ‘browser’ doesn’t contain a valid alias configuration angular

A common error when using webpack to bundle your Angular application is Field ‘browser’ does not contain a valid alias configuration.

In other words, webpack is unable to resolve the path to the module you’re trying to import. This error can be caused by the following:


Verify that the path to the file you are trying to import is correct. Be sure to check for typos, case sensitivity, and missing extensions. 

For example, if you have a file named input.component.ts in your components folder, you should import it as import { InputComponent } from './components/input.component';


If you are using aliases in your webpack configuration, make sure they are defined correctly. Use the resolve.alias option to map a name to a path, and also use the same name when importing modules.

You should use the resolve.alias option to map a name to a path, and use the same name when importing the module. 

For example,

if you have an alias like components: path.resolve(__dirname, 'src/components'), you should import the module as import { InputComponent } from 'components/input.component';


If your entry value is pathed correctly relative to your context value, webpack will not be able to locate the modules you are importing if they are not aligned.

The entry value is the file webpack starts bundling from, while the context value is the directory used to resolve entry points. 

For example, if your entry value is ./src/main.js and your context value is __dirname, you should have a file named main.js in your src folder


In webpack, using an alias that is already taken by another module or package may cause conflicts and confusion.

For instance, if you use redux as an alias, webpack will look for the redux package rather than your alias.

For example, if you use redux as an alias, webpack may try to look for the redux package instead of your alias. You should use a unique name for your alias, or prefix it with something like @
