I've seen some anti-Gatsby sentiment bubbling around recently. I normally ignore articles like this when they come along. It seems like every few weeks there is an article telling me I should abandon React for Vue, then that Vue is dead long live Svelte, and a few weeks later another article saying React was fine.
A lot of the things I was reading made a lot of sense, and I agreed with the points. Gatsby had annoyed me with the way it splits your site in two with the GraphQL API in the middle. I like GraphQL, I've written two full-blown APIs using it, but I find Gatsby's GraphQL API hard to extend and can sometimes trap you into having to pull in lots of data for a simple query.
So why Next.JS? Next.JS separates rendering and generation within the same files, unlike Gatsby where you have to write an isolated
gatsby-node.js and use plugins to parse/fetch data and then output a page list.
I didn't start this rewrite expecting to go all the way to launch it. Whenever I want to try new technologies, I rebuild this site, it is relatively complex and has quite a few features which makes it a great test case.
This rewrite has shown how much work had gone into the old Gatsby site and how powerful that platform was, Saying that, I do find that this Next.js site just makes more sense.
I went big into the Typescript in this site. One of my gripes with Gatsby, and GraphQL, in general, is that I have to manually type the result of queries which, of-course leads to bugs.
So what have I done here?
Looking at posts, I have a
BasePost interface that describes the basic data I have on the post before I parse it.
BasePost with the data from the front matter and content of the post which requires actually reading the file. The functions that fetch the data then return this
Post type. My data fetching functions take a
fields argument so that I can limit the data being returned. Next.js creates a data file for each page, no need to have the whole page's content unless I need it. Fetching limited data then becomes as easy as calling one of the fetch functions.
1// Home Page2const posts = await getPosts(['slug', 'title', 'href', 'year', 'month', 'day', 'lead'])34// Post page5const post = await getPostBySlug(6 [7 params.year as string,8 params.month as string,9 params.slug as string10 ],11 ['slug', 'title', 'content', 'lead', 'href', 'tags', 'year', 'month', 'day']12)Language ts
Pick<T> allows me to make sure that the type exactly matches the data I am requesting. No more making sure I keep a query and type in sync.
Because these data fetching functions are just typescript I can use them outside Next.js as well, in my social image generator for example. That post is outdated now and I may re-visit it as my new method is a lot cleaner.
The other new resource I wanted to try out this time was Tailwind CSS. I had used it on a React App within the company before and wanted to give it a go on something more creative.
I like Tailwind, I find it extremely powerful without getting in the way of what I want to do like other CSS frameworks. Tailwind requires you to know CSS, which I think is what I like about it. I found with Bootstrap and others that my own stylesheet was just me throwing
!important at everything to make a buttons shadow slightly less obvious.
Tailwind is more than just a framework, the stylesheet in use on this site is generated by Tailwind. My colours, sizes, and any other units I have named are merged into the stylesheet. For example I added a width of
dbl, with a value of
200vw, which can be used with any width class in Tailwind like
max-w-dbl and many more.
I also use purgecss to remove all the unused classes and keep tailwind as light as possible for this site.
As with my Gatsby site I've made the source code of this site available on GitHub. You'll see my process of developing the site as I kept it private until launch.
