How to Fix 404 Not Found Nginx Errors in Vue.js Applications

=====================================================================================

When building single-page applications (SPAs) with frameworks like Vue.js, it's not uncommon to encounter '404 Not Found' errors when trying to access certain routes. In this article, we'll explore some common causes of these issues and provide step-by-step solutions for resolving them using Nginx as the web server.

### Understanding 404 Errors

Before diving into the solution, let's quickly recap what causes a 404 error:

* When you refresh your browser or access an application directly through its URL (instead of clicking on it from within the app), the browser requests the initial HTML file specified in the `` tag.

* If this file doesn't exist at that location, Nginx will return a '404 Not Found' error.

### Solution 1: Configure Vue CLI to Generate Correct ClientBaseURL

When you create a new project using `vue-cli` version 3.x or later, ensure that the correct client-side base URL is set in your `public/index.html` file. You can do this by running:

```bash

npm run build --target production --progress-templates

```

This command will generate a `dist` directory containing all necessary files for deployment.

### Solution 2: Configure Nginx to Serve Static Files Correctly

If you're still experiencing issues, check your Ngin' configuration. You'll need to make sure that static assets are served correctly by adding the following lines within the `server` block of your Nginx conf file:

```bash

# Set up a directory for serving static files.

location /dist {

try_files $uri @index.html;

}

# If all other attempts fail, serve an error page with a 404 status code.

if !-f $request_uri/index.html && -d $document_root/website/$1.$2 {

return 302 permanent @home;

}

```

These directives tell Nginx to try serving static files from the `dist` directory first and then fall back to index.html for all other requests.

###

By following these steps, you should be able to resolve '404 Not Found' errors in your Vue.js applications when using Nginx as your web server. Remember that a correct configuration is key to ensuring smooth user experience across different environments and scenarios.
