When integrating an Angular application with Laravel and deploying it behind Nginx, you may encounter an empty or blank page when accessing the Angular application through a specific URL path.<\/p>\n\n\n\n
For example:<\/p>\n\n\n\n
http:\/\/server-ip\/angularclient<\/pre>\n\n\n\nAlthough the page may appear to load, inspecting the page in the browser’s developer tools may show 404 errors for CSS, JavaScript, HTML, or other application files<\/strong>.<\/p>\n\n\n\n
This issue can occur when the Angular application’s base URL does not match the path configured in the Nginx routing configuration.<\/p>\n\n\n\n
Prerequisites<\/h2>\n\n\n\n
Before troubleshooting the issue, make sure you have:<\/p>\n\n\n\n
\n
- Access to the Nginx configuration.<\/li>\n\n\n\n
- Access to the Angular application’s
index.html<\/code> file.<\/li>\n\n\n\n- Basic knowledge of Angular and Nginx configuration.<\/li>\n\n\n\n
- Access to the server hosting the application.<\/li>\n<\/ul>\n\n\n\n
Implementation<\/h2>\n\n\n\n
1. Check the Nginx Configuration<\/h3>\n\n\n\n
When Angular is being served through Nginx under the
\/angularclient\/<\/code> path, the Nginx configuration can look like this:<\/p>\n\n\n\nlocation \/angularclient\/ {\n\n proxy_pass http:\/\/127.0.0.1:4200\/;\n\n}<\/pre>\n\n\n\nHere, requests made to:<\/p>\n\n\n\n
http:\/\/server-ip\/angularclient\/<\/pre>\n\n\n\nare forwarded to the Angular application running on:<\/p>\n\n\n\n
http:\/\/127.0.0.1:4200\/<\/pre>\n\n\n\n2. Verify the Angular Base URL<\/h3>\n\n\n\n
Next, check the
index.html<\/code> file of the Angular application.<\/p>\n\n\n\nThe
<base href><\/code> should match the path configured in Nginx:<\/p>\n\n\n\n<base href=\"\/angularclient\/\"><\/pre>\n\n\n\nThe trailing
\/<\/code> is important because the application is being accessed under the\/angularclient\/<\/code> path.<\/p>\n\n\n\n3. Verify the Browser Console<\/h3>\n\n\n\n
After updating the configuration, open the Angular URL in the browser and inspect the developer tools.<\/p>\n\n\n\n
If the base path and Nginx routing are correctly configured, the browser should request the Angular application’s CSS and JavaScript files from the correct
\/angularclient\/<\/code> path instead of requesting them from the server root.<\/p>\n\n\n\nConclusion<\/h2>\n\n\n\n
An empty Angular page behind Nginx can occur when the Angular application’s base URL does not match the path used by Nginx.<\/p>\n\n\n\n
When Angular is configured under
\/angularclient\/<\/code>, ensure that the Nginx location and Angular<base href><\/code> use the same path:<\/p>\n\n\n\nlocation \/angularclient\/ {\n\n proxy_pass http:\/\/127.0.0.1:4200\/;\n\n}<\/pre>\n\n\n\nand:<\/p>\n\n\n\n
<base href=\"\/angularclient\/\"><\/pre>\n\n\n\nKeeping these paths consistent helps prevent 404 errors for Angular application assets such as CSS, JavaScript, and HTML files.<\/p>\n\n\n\n
Frequently Asked Questions<\/h2>\n\n\n\n
1. Why does my Angular application show a blank page on Nginx?<\/h3>\n\n\n\n
A common reason is that Angular is generating asset URLs that do not match the path configured in Nginx. Check the
<base href><\/code> inindex.html<\/code> and compare it with the Nginx location path.<\/p>\n\n\n\n2. What should the Angular base href be when using
\/angularclient\/<\/code>?<\/h3>\n\n\n\nIf the application is served under
\/angularclient\/<\/code>, configure:<\/p>\n\n\n\n<base href=\"\/angularclient\/\"><\/pre>\n\n\n\n3. Why are CSS and JavaScript files returning 404 errors?<\/h3>\n\n\n\n
This can happen when the browser requests the Angular assets from an incorrect path. Verify that the Angular
<base href><\/code> matches the Nginx routing path.<\/p>\n\n\n\nRelated Article<\/h2>\n\n\n\n
