When i refresh a page, i get Error 404

Working well with Ionic LocationStrategy provider for app.module.ts as described here

Build your Ionic sources with ionic build --prod, and serve the generated www folder with NGINX.

NGINX default.conf configuration example :

 server {
    ...
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        try_files /index.html =404;
    }
    ...

NGINX’s try_files directive will do the job with Ionic PWA routing. Page refresh with F5 will not display 404 anymore :slight_smile:
