How Do You Create a Local Override?

You can create a local override directly within your browser's developer tools, particularly from the Network panel.

## Creating Local Overrides

One primary way to create a local override, as described in the reference, is by interacting with a resource loaded from the network:

*   **View Network Resources:** Open your browser's developer tools and navigate to the Network panel.
*   **Select a Resource:** Load a web page or application, and observe the resources (HTML, CSS, JS, images, API calls) listed in the Network panel. Click on a specific resource you want to override.
*   **Initiate Override Creation:** When viewing the contents or details of that resource, look for a button or option to create an override. According to the reference dated 14-Jan-2020, this is done by **clicking the (Create Local Override) button when viewing the contents of a resource that was loaded from the network**.

## Override Options

Clicking the create override button will typically present you with a dropdown menu offering different types of overrides:

*   **Create Request Local Override:** Allows you to modify aspects of the *request* before it is sent.
*   **Create Response Local Override:** Allows you to modify the *response* received from the server.
*   **Block Request URL:** Simply blocks the specific network request from happening.

Choosing 'Create Request Local Override' or 'Create Response Local Override' will usually prompt you to select a folder on your local disk where the override files will be stored and managed by the browser.

By following these steps, you can intercept and modify network resources locally for testing or debugging purposes.
