React router

chrome devtools message

AI Overview The message “No routes matched location /.well-known/appspecific/com.chrome.devtools.json” indicates that your application’s router (e.g., React Router, Vue Router) is attempting to handle a request from Chrome DevTools for a specific JSON file, but no route is defined within your application to match that path. Explanation: Chrome DevTools uses a special JSON file located at /.well-known/appspecific/com.chrome.devtools.json to communicate with your development server, particularly for features like workspace integration and source map management. When DevTools tries to access this file, the request is intercepted by your application’s routing system, and since there’s no explicit route defined for this path, the “no routes matched” error occurs. Solution: To resolve this, you need to ensure that the /.well-known/appspecific/com.chrome.devtools.json file is served directly by your development server, bypassing your application’s router. Create the directory and file: In the public or static folder of your project (the folder that is served directly by your web server), create the following directory structure and file: Code

public/
└── .well-known/
    └── appspecific/
        └── com.chrome.devtools.json

Add content to the JSON file: The com.chrome.devtools.json file can be empty (containing just {}), or it can contain specific configuration for DevTools if you’re using advanced features like workspace mapping. For basic functionality, an empty JSON object is sufficient. Code

{}

By placing this file in the public directory, your web server will directly serve it when Chrome DevTools requests it, preventing the request from being routed through your application’s client-side routing system. This eliminates the “no routes matched” error for this specific DevTools request.
