'How to create an auto-publishing Photo Blog, powered by Next.js, Deno and Syncthing'
Why build a Photo Blog in 2021?
Nowadays Instagram is the standard for photo blogging. I really don't like Instagram for a number of reasons including giving my data to the Facebook algorithm, and the whole idea of sharing with everyone by default. I recently looked into an open source alternative: Pixelfed and tried out running my own server. It's a nice service, but to share my photos with my family and friends the barrier of entry is too high. Another alternative is to run a Ghost blog, which I have tried. However, posting a new entry with pictures is pretty tedious and I found myself not posting as much as I wanted.
What I am trying to achieve is pretty simple: Just a website where each page is an album with pictures of my everyday life that can be viewed by my close family and friends, if they want. And the most important: A very very easy way to publish new photos and albums.
Overview
Technologies used:
From an end users perspective there is nothing interesting. Just a website that connects to an API which serves some images.
From the website admin point of view it gets more interesting. Let's say you want to upload a new album with some images. Just copy the images on your phone to the special folder on your phone, wait a couple of seconds and boom! Your new album has been published! But how does it work?
Syncthing - Sync Photos
Syncthing is a peer-2-peer file syncing service which doesn't require any central server like e.g. Dropbox. For this project I have a folder on my server that is synced with a folder on my smartphone. This can also be synced with another device if you want to edit/add photos from another device.
Deno - Serve Photos
Deno is the new kid on the block that will eventually replace Node.js. With deno
I built a simple HTTP server, running in a Docker container, that reads from a
mounted folder called files. The endpoint /list will return each folder name
that exists in the main folder. The endpoint /album/:albumName will list all
the images in the given album folder folder. And finally the endpoint
/photo/:albumName/:photoName returns the image.
Look at the code
Next.js - Show Photos
Next.js is a JS Framework on top of React and Node.js from Vercel. The website basically have 2 routes. The index route will list the albums. When clicking on an album the page will list all the photos in the album.

Further Automation
To make the deployment easy I am leveraging Vercel to host the frontend and to
auto-deploy on each push to master.
I also setup Docker Hub to listen for pushes to master and auto-publish a new
Docker image. Currently this flow is semi-automated cause I still need to login
to my server and pull the latest image and restart the container.
Conclusion
That's it! If you follow these steps you now have a photo blog you can share with your friends and super easily update with new albumbs and photos.
