GoSquash

⚠️ This is not production-ready code! Although I've deployed it, I'm an irresponsible scoundrel.

This is a tiny app designed to compress images for web requests. It's far from production ready and is mainly for my own learning!

The brief for this app is to sit alongside a Django webapp (to which these pesky users keep uploading massive images) and serve user-uploaded files which are compressed on the fly. Ideally this would be integrated with some sort of Django plugin, but that's beyond the scope of the project for now.

I wrote a blog post about the project if you'd like to learn more.

Deployment Steps

I've deployed this behind Nginx on a Linux server running Ubuntu with the following config.

Bring on systemd

To keep this Gopher running in the background we'll use systemd with the following config:

[Unit]
Description=gosquash

[Service]
Type=simple
Restart=always
RestartSec=5s
ExecStart=/home/user/go/gosquash/main

[Install]
WantedBy=multi-user.target

At the following path: /lib/systemd/system/gosquash.service

And kick it off using: sudo service gosquash start

You can check the status using sudo service gosquash status

Nginx Config

Under /etc/nginx/sites-available I modified the config to include:

# Gosquash product images
location /product-images {
    proxy_pass http://localhost:9990;
}

Then reload Nginx: sudo nginx -s reload

Next Up

I want to do the following:

  • Write a fancy todo list
  • Move config to command line args
  • Figure out why routing doesn't work with the config above (right now it only works when routing to root /)
  • Add a batch job for compressing a set of images all in one go
  • Benchmark the mother
  • Add proper logging to an output file
