vite alias not working, how to fix it?

When using Vite, you may encounter issues where aliases are not working as expected. Here are some common causes and solutions to address this problem:

1. Incorrect Alias Configuration

Ensure that the alias configuration is correct in your vite.config.js or vite.config.ts file. Check for any typos or mistakes in the alias path or the corresponding value. Also, make sure the path is relative and starts with ./ or ../.vite.config.js or vite.config.ts file. Check for any typos or mistakes in the alias path or the corresponding value. Also, make sure the path is relative and starts with ./ or ../.

2. Module or Folder Not Found

Verify that the module or folder you are trying to alias actually exists and is accessible. If the module or folder is missing or inaccessible, Vite cannot resolve the alias.

3. Node API Not Used

If you are using a Node API, you may need to configure Vite to resolve Node modules. In your vite.config.js or vite.config.ts, opt into Node.js API support by setting optimizeDeps.include to include the necessary Node modules.

4. Browser Context

When working with aliases in a browser context, check if your application is running on the correct address or port. Sometimes, aliases may not resolve if the application is running on localhost but the aliases are configured for a different address or port.

5. Improper Ordering

Ensure that the alias configuration is placed before any conflicting rules in the vite.config.js or vite.config.ts file. Aliases are resolved in the order they are defined, so later rules may override earlier ones.

6. Cache Issues

If you have made changes to your alias configuration but the changes are not taking effect, clear the Vite cache by running the following command:

<code class="text">npx vite clean</code>

7. Aliasing from the node_modules Directory

To alias modules from the node_modules directory, you can use a special @node_modules prefix. For example, if you want to alias my-module in the node_modules
