Thought I would do a series of posts on moving my blog from a Tumblr-hosted and themed site to a Tumblr powered Next.js app.
You might reasonably ask, “Why would anyone want to do that when there are so many actual CMS options available?”.
In my case, it’s mostly sentimental. Way back when I was deciding whether to switch careers and try coding full time, I took a lot of freelance jobs converting PSDs to Tumblr themes and I’ve been using it ever since.
But, I finally wanted a little more control over my blog and a good excuse to experiment more with Next.js so I decided to mix it up just a little. Let’s dig into some of the decision making, adventures in data fetching, and general idiosyncrasies that come with using Tumblr as a CMS.
How To Set It Up
Starting at the beginning, the very first question was how to set everything up. Where should the site and the code live? How do you share the parts that need to be shared? It seems simple but there are a lot of options.
Keeping with the original Tumblr setup, I decided to create a new app for my blog instead of trying to integrate it with the rest of my site (which was already using Next.js). I wanted to use Vercel for hosting which meant I would just need to update my subdomain records once everything was up and running.
Since Tumblr templates are basically HTML files that include Tumblr’s custom blocks and variables, I’d never really shared much code between my blog and the rest of my site even though they look pretty similar. I had a small script to generate stylesheets but that was it. Using Next.js for both opened up the possibility of sharing React components, variables, and utilities in addition to CSS.
To figure out how to do that, I followed one article (6 Ways to Share React Components in 2020) to another (4 Git Submodules Alternatives You Should Know) and finally landed at Git subtree: the alternative to Git submodule for step-by-step instructions.
Any solution that required publishing components, individually or as a monorepo, seemed like overkill for a smallish, one dev project. Git subtrees provided a way to nest one repo as a subdirectory in others which was exactly what I wanted. I split out shared components like the header, footer, form elements, etc. into a separate repo, ran the commands from the tutorial above in my blog and site repos to hook it all up, and voila. No copying and pasting duplicate code between sections and no publishing to NPM or other third-parties.
So that’s the foundation, stay tuned for the next installment for data fetching and some actual code!
