How to Solve Angular Case Sensitive URL Path with Serializer Code

If you are working with Angular framework, you might have encountered the issue of case sensitive URL paths. Angular routing is case sensitive by default, which means that if you have two URLs that only differ by case, Angular will treat them as different routes. This can lead to unexpected behavior and make your application harder to maintain.

One way to solve this issue is to use a serializer code in your Angular application. A serializer code is a piece of code that converts the URL path to a standardized format, making it case insensitive. This allows you to define your routes in a case insensitive manner, while still preserving the original case of the path when navigating to the URL.

Here’s an example of how you can use a serializer code to solve the case sensitive URL path issue in Angular:


import { DefaultUrlSerializer, UrlTree } from '@angular/router';

export class CaseInsensitiveUrlSerializer extends DefaultUrlSerializer {
parse(url: string): UrlTree {
// Convert the URL to lowercase
url = url.toLocaleLowerCase();
return super.parse(url);
}
}


In this example, we define a new class called CaseInsensitiveUrlSerializer that extends the DefaultUrlSerializer provided by Angular. We override the parse method to convert the incoming URL to lowercase using the toLocaleLowerCase method, and then call the super.parse method to parse the URL using the default Angular logic.

Once you have defined the serializer code, you can then use it in your Angular application by providing it as a custom serializer in the app.module.ts file:


import { NgModule } from '@angular/core';
import { RouterModule, UrlSerializer } from '@angular/router';
import { CaseInsensitiveUrlSerializer } from './case-insensitive-url-serializer';

@NgModule({
imports: [RouterModule],
providers: [
{ provide: UrlSerializer, useClass: CaseInsensitiveUrlSerializer }
]
})
export class AppModule { }


By providing the custom serializer in the app.module.ts file, you can ensure that all the URLs in your application are treated in a case insensitive manner, making it easier to define and maintain your routes.

In conclusion, using a serializer code is a powerful technique to solve the case sensitive URL path issue in Angular. By converting the incoming URLs to a standardized format, you can make your application more user-friendly and easier to maintain. Give it a try in your Angular applications and see the difference it makes!
