This is a proof-of-concept project to tackle Javascript loader issue on Sentry (see this issue: getsentry/sentry#22715).

1. From your already set up self-hosted instance, go to http://your-sentry-instance.dev/settings/account/api/auth-tokens/new-token/ -- then generate a new token. Set Project and Organization permissions to "Admin". Then copy the token and save it somewhere safe.
2. On your docker-compose.yml file, add this additional container:

   services:
     sentry-loader:
       <<: *restart_policy
       image: ghcr.io/aldy505/sentry-loader:edge
       environment:
         SENTRY_AUTH_TOKEN: "your auth token earlier"
         JS_SDK_VERSION: "8.19.0" # You can configure this one later on
         SENTRY_PUBLIC_HOSTNAME: "your-sentry-instance.dev" # Without http:// or https:// prefix. But provide ports if you're not using 80/443.
         USE_HTTPS: "false" # Set to true if you're using HTTPS on the "SENTRY_PUBLIC_HOSTNAME" earlier

3. On your nginx/nginx.conf, add these entries:

   upstream loader {
      server sentry-loader:3000;
      keepalive 2;
   }
   
   server {
      listen 80;
      # ....
   
      location ^~ /js-sdk-loader/ {
         proxy_pass http://loader;
      }
      location ^~ /8.19.0/ { # The value is from the `JS_SDK_VERSION` earlier
         proxy_pass http://loader;
      } 
      # You must put these before the `location /` block
      location / {
         proxy_pass http://sentry;
      }
   }

4. No need to re-run the ./install.sh script. All you need to do is:

   sudo docker compose up -d sentry-loader nginx

There's all to it. You should be good to go.
