While Next.js can handle static sites, we've had a few issues with it, notably a performance hit at runtime and some bugginess around routing and SSR. Gatsby being fully intended for high-performance static sites makes it a great technical fit for the Shields frontend. The `createPages()` API should be a really nice way to add a page for each service family, for example.
This migrates the frontend from Next.js to Gatsby. Gatsby is a powerful tool, which has a bit of downside as there's a lot to dig through. Overall I found configuration easier than Next.js. There are a lot of plugins and for the most part they worked out of the box. The documentation is good.
Links are cleaner now: there is no #. This will break old links though perhaps we could add some redirection to help with that. The only one I’m really concerned about `/#/endpoint`. I’m not sure if folks are deep-linking to the category pages.
There are a lot of enhancements we could add, in order to speed up the site even more. In particular we could think about inlining the SVGs rather than making separate requests for each one.
While Gatsby recommends GraphQL, it's not required. To keep things simple and reduce the learning curve, I did not use it here.

This removes `LONG_CACHE` and its descendants, which was a feature that added `?maxAge` to the live preview badges in the frontend. Since they are all static that is no longer needed, as the static badges all have longer cache timeouts regardless.
- The goal of this PR is:
- Consume the new service-definition format. (#2397)
- Make the frontend more readable.
- Behavior changes:
- I changed the **Image** field in the markup modal to show only the path.
- I added another click-to-select field below that shows the complete URL.
- This made it easier to suppress the live badge preview while it contains placeholders like `:user` or `:gem`, a minor tweak discussed at https://github.com/badges/shields/issues/2427#issuecomment-442972100.
- The search box now searches all categories, regardless of the current page. (This is an improvement, I would say.)
- I did not deliberately address performance, though I ripped out a bunch of anonymous functions and avoided re-filtering all the examples by category on every render, which I expect will not hurt. I haven't really tested this on a mobile connection and it'd be worth doing that.
- It would be great to have some tests of the components, though getting started with that seemed like a big project and I did not want to make this any larger than it already is.
It's a medium-sized refactor:
1. Replace `BadgeExamples`, `Category` and `Badge` component with a completely rewritten `BadgeExamples` component which renders a table of badges, and `CategoryHeading` and `CategoryHeadings` components.
2. Refactor `ExamplesPage` and `SearchResults` components into a new `Main` component.
3. Rewrite the data flow for `MarkupModal`. Rather than rely on unmounting and remounting the component to copy the badge URL into state, employ the `getDerivedStateFromProps` lifecycle method.
4. Remove `prepareExamples` and `all-badge-examples`.
5. Rewrite the `$suggest` schema to harmonize with the service definition format. It's not backward-compatible which means at deploy time there probably will be 10–20 minutes of downtime on that feature, between the first server deploy and the final gh-pages deploy. 🤷♂️ (We could leave the old version in place if it seems worth it.)
6. Added two new functions in `make-badge-url` with tests. I removed _most_ of the uses of the old functions, but there are some in parts of the frontend I didn't touch like the static and dynamic badge generators, and again I didn't want to make this any larger than it already is.
7. Fix a couple bugs in the service-definition export.
This continues a consistency update we’ve been making to standardize on URL based on a recommendation from WHATWG: https://url.spec.whatwg.org/#goals
This also helps with copying and pasting between all-badge-examples and new-style services, where it’s otherwise easy to make a mistake.
Ref: #1322#1341
- Present 'downloads', 'version', etc as pages
- Don't show any badges on the index page,
just links to categories.
- Tweak search so we can search all badges
from the index page, but without rendering
every badge as soon as we press a key.
