Closes#37.
Gitea generates an OpenAPI 3.0 document since 1.27 (`templates/swagger/v1_openapi3_json.tmpl`, renamed to `templates/swagger/v1-openapi3.generated.json` on main, served by an instance at `/openapi3.v1.json`), but this site never picked it up and still published Swagger 2.0 only. That is what the issue is about: code generators such as `openapi-python-client` reject the document with "You may be trying to use a Swagger document; this is not supported by this project".
**What this does**
- `update_api_docs.sh` downloads the OpenAPI 3.0 document next to the Swagger 2.0 one, rewrites the same placeholders (they sit in `servers` instead of `basePath`) and writes `static/openapi3-latest.json` and `static/openapi3-<minor>.json`. Versions that do not have one (1.26 and older) are skipped with a message and keep their Swagger 2.0 document.
- The OpenAPI 3.0 document is rendered where it exists (`/api/` and `/api/next/`), the older versions keep rendering Swagger 2.0. Both documents describe the same api and carry the same operation ids, so no url of an operation page changes; the `basePath` normalization is now only applied to the Swagger 2.0 documents, since a full url in `servers` is valid.
- The overview page of each version links both documents for download, which is what the issue actually needs: `https://docs.gitea.com/openapi3-27.json` for the current release, `https://docs.gitea.com/openapi3-latest.json` for gitea main.
- The scheduled workflow now refreshes and proposes both documents of gitea main.
**Verification**
- `pnpm dlx @redocly/cli lint static/openapi3-latest.json`: valid, only content warnings that come from upstream (missing 4xx responses, ambiguous paths).
- `openapi-python-client generate --path static/openapi3-latest.json`, the tool from the issue, generates a client. The only warning left is `POST /markdown/raw`, whose request body is `text/plain`.
- Operation ids of `static/swagger-27.json` and `static/openapi3-27.json` are identical (481 on both sides), so the operation pages keep their urls.
- Built the api product and compared a rendered operation page against the Swagger 2.0 one: same sections, the request body is now marked required where the document says so.
The released Swagger 2.0 documents are kept: they are the only description 1.26 and older ever produced, and some tooling still expects them.

Replace [#307](https://gitea.com/gitea/docs/issues/307)
Closes [#237](https://gitea.com/gitea/docs/issues/237)
## Summary
Rebuilds docs.gitea.com with [Astro](https://astro.build) and [Starlight](https://starlight.astro.build), replacing Docusaurus. Every
published url keeps working and no content file was moved: the site is a new rendering layer over the existing `docs/`, `versioned_docs/`, `i18n/`, `runner-docs/` and `static/swagger-*.json` trees.
For the first time the API reference is part of the site rather than a Redoc
bundle: all seven swagger documents are rendered into real pages, one per
operation, so they are linkable, crawlable and searchable.
## Why
- the Docusaurus build needs an 8 GB heap and about 2 minutes for 2478 pages;
the Astro build produces 5751 pages, API reference included, in about 100
seconds
- the API reference was a single client rendered Redoc page per version, absent
from the site search and from search engines
- sidebars, version lists and language lists were configured in three different
places and drifted apart
## What is in here
- **`packages/content-loader`** — the product × version × language matrix
(`products.ts`) and an Astro content loader that reads the existing markdown
trees directly. The matrix is the single source of truth: content loading,
sidebars, the version and language pickers, the version banner, the search
facets and the API schemas are all derived from it.
- **Content compatibility** — frontmatter `slug`, `sidebar_position` and
`sidebar_label` keep working, `_category_.json` still drives sidebar labels,
order and the generated category pages, `@version@` style release variables are
still substituted, `:::note` admonitions become Starlight asides and the 2778
relative `*.md` links are rewritten to urls while the site is built.
- **API reference** — `starlight-openapi` renders the seven swagger documents.
Operation urls are hyphenated (`/api/operations/list-admin-workflow-jobs/`),
the sidebar shows the operations of the version being read with a coloured
HTTP method badge, and the overview page links to one page per tag instead of
repeating all 484 operations.
- **Navigation** — a version picker that follows the reader to the same page in
another version, a language picker that only offers the languages the current
product is published in, and product links for Docs, API, Runner and
Enterprise.
- **Theme** — the light and dark palettes of about.gitea.com, mapped onto the
Starlight variables.
- **Search** — Pagefind by default; Algolia DocSearch takes over when
`PUBLIC_DOCSEARCH_APP_ID` and `PUBLIC_DOCSEARCH_API_KEY` are set. Every page
carries `docsearch:product`, `docsearch:version` and `docsearch:language` meta
tags, so a search stays inside what is being read.
`cloudflare/docsearch-crawler.json` holds the crawler configuration.
## Bugs fixed along the way
- `GET /user/applications/oauth2` and `GET /user/applications/oauth2/{id}` have
operation ids that only differ in case, so they collapsed onto the same url
and one of the two pages was silently dropped. They are now
`user-get-oauth2-application` and `user-get-oauth2-application-by-id`.
- The API overview and every tag page were all titled "Overview".
## Url compatibility
The routes of both builds were compared page by page during the migration with
`scripts/url-diff.mjs`:
```
identical: 2368, missing: 0, accepted: 110, added: 3292
```
The 110 accepted ones are all redirected in `cloudflare/_redirects`: the
localized copies of the English-only API and Runner docs, the Docusaurus search
page, and `/1.27/`, `/runner/3/`, `/api/1.27/` which are aliases of the versions
served at the product root. The added ones are the API operation and tag pages
plus the routes the Starlight language fallback serves in English when a
translation is missing — Docusaurus answered those with a 404.
## Workflows
- `checks` builds the site and type checks it on every pull request
- `Build and Publish Docs site` publishes `sites/docs/dist` to S3/CloudFront and
to Cloudflare Pages, and copies `cloudflare/_headers` and
`cloudflare/_redirects` into the deployment
- `update swagger files` and `update runner reference` are unchanged, they only
touch content
- `make cut-version PRODUCT=docs VERSION=1.28` replaces
`docusaurus docs:version`
## Removed
`docusaurus.config.js`, the swizzled theme under `src/`, and the Docusaurus UI
translations (`i18n/*/code.json`, `i18n/*/docusaurus-theme-classic/`). The
strings those carried — the product names, the footer column titles and the
outdated translation notice — were ported to
`sites/docs/src/config/strings.ts`; Starlight ships the rest of its interface in
both Chinese locales. The documentation content itself is untouched.
## Follow ups
- nine relative links are broken in the sources and reported by every build, the
same ones Docusaurus warned about; `GITEA_DOCS_STRICT_LINKS=true` turns them
into an error once they are fixed
- `cloudflare/worker.js` has to be deployed for `/enterprise/` to keep resolving
- the Algolia index has to be created and crawled before the search credentials
are set
## Testing
```shell
make install
make serve-fast # english, the version served at the root
make serve # the whole matrix
make build # 5751 pages
make check # 0 errors
make serve-built # build and serve, the only way to try the search locally
```
