a09975b95f Migrate docs site: Docusaurus config, Algolia, OpenAPI pipeline, and CI (#37402)
* Align Docusaurus config for monorepo, wire Algolia DocSearch (P6)

Fixes projectName/editUrl/path references left over from the docs-unified
repo split, adds trailingSlash for predictable CloudFront 404 handling, and
wires an Algolia search block into themeConfig that's only included when
credentials are present (Docusaurus's schema rejects an empty appId/apiKey,
so this keeps builds green with or without them). Also fixes the
sidebar/redirect generator scripts, which still pointed at the pre-rename
docs/ directory instead of main/, and adds docs/Makefile,
.env.local.example, and an updated README for local dev.

* Wire OpenAPI generation to api/v4/source and add docs-ci.yaml (P7)

Replaces build-openapi.mjs's custom YAML-merge implementation with a thin
wrapper around the canonical `make -C api build` target, keeping only the
MDX sanitization step (quote/autolink fixes) that docusaurus-plugin-openapi-docs
needs. Adds a "prebuild" npm script so `npm run build` regenerates the spec
automatically, and ignores the generated api/v4/html artifacts (narrow form,
since ssr_template.hbs and static/favicon.ico under that path are committed).

Also adds docs-ci.yaml as a path-scoped PR/master build+typecheck gate for
the docs site, replacing the legacy `docs` repo's Sphinx-based ci.yml now
that docs live in this monorepo.

* Rename OpenAPI prebuild script for clarity

"prebuild" is an npm lifecycle hook name (auto-runs before "npm run build"),
not a descriptive name, so `npm run prebuild` didn't signal it's specifically
about OpenAPI generation. Split it into "build:openapi" (the actual script,
runnable directly and self-explanatory) with "prebuild" now just delegating
to it, preserving the automatic pre-build trigger.

* Regenerate sidebars automatically before dev/build (P7 fixup)

documentation.generated.json and developers.generated.json are gitignored
and nothing produced them on a fresh checkout, so both `npm start` and
`npm run build` failed with MODULE_NOT_FOUND outside a working tree that
happened to have stale copies lying around. Wire the sidebar generators
into `prestart`/`prebuild` so they're always regenerated first.

* Remove docs/site/.env.local.example

There's a single Algolia DocSearch app for docs.mattermost.com; credentials
aren't distributed to individual developers, so a per-dev .env.local
workflow doesn't apply. Credentials are only ever injected in CI/CD via
repository variables. Local builds/dev server run fine without them (the
Algolia block in docusaurus.config.ts is conditional).

* Wire OpenAPI doc generation into prestart/prebuild, drop unused Makefile

docusaurus-plugin-openapi-docs requires a separate `docusaurus gen-api-docs`
CLI step to populate docs/api/reference/ (gitignored) — nothing was
invoking it, so a fresh checkout's npm start/build failed the same way the
sidebar JSONs did. Split build:openapi into build:openapi:spec (slow, runs
make -C api build) and build:openapi:docs (fast, generates MDX from the
existing spec), and wire prestart to reuse an existing spec instead of
rebuilding it every dev-server start.

Also drops docs/Makefile: four of its five targets were pure passthroughs
to npm scripts, unreferenced by CI or anything else, and there's no
repo-wide `make -C <dir>` convention to fit into.

Note: a duplicate-doc-id build failure (operationId `status` in the
Playbooks OpenAPI spec colliding with the main API's `status` tag) is
being fixed separately in mattermost-plugin-playbooks.

* Fix stale docs/ reference in sidebar generator's error message

The existence check still hardcoded "docs/" in its error text after SRC
was repointed to main/. Use the SRC constant in the message so it can't
drift out of sync with the actual path again.

* remove code comment

* Drop unused artifact upload from docs-ci.yaml

Nothing consumes it: P9's docs-cd.yml will rebuild independently on push
to master rather than downloading it via workflow_run (avoids workflow_run
trigger footguns for an infrequent, cheap-enough rebuild), and P10's
preview build always needs its own independent build anyway (bakes a
per-PR BASE_URL). This was carried over from the old docs repo's ci.yml
out of habit; that repo's own PR-time uploads had the same unused-artifact
issue (only cd.yml's post-merge run ever consumed it).

Mattermost Documentation Site

Docusaurus workspace for docs.mattermost.com, living in the mattermost/mattermost monorepo at docs/site/.

Content layout

Directory Route Description
docs/main/ / User and admin documentation
docs/develop/ /developers Developer documentation
docs/api/ /api API reference intro + generated OpenAPI pages

Paths are relative to the repository root. The Docusaurus site reads them via the relative paths ../main, ../develop, ../api (from docs/site/).

Prerequisites

  • Node.js ≥ 20 — use nvm use inside docs/site/ to pick up .nvmrc
  • Go and make (required only for the OpenAPI prebuild step — see below)
  • Vale ≥ 3 (for content linting)

Local development

cd docs/site
npm ci
npm start          # dev server at http://localhost:3000

Sidebar generation

The documentation and developers sidebars are generated from the content directories (sidebars/documentation.generated.json / developers.generated.json, both gitignored) by npm run build:sidebars. Docusaurus imports these files directly, so they must exist before docusaurus start or docusaurus build runs — on a fresh checkout there's no other source for them. This is wired automatically via the prestart and prebuild npm lifecycle hooks, so plain npm start / npm run build just work.

(sidebars/active-redirects.json, by contrast, is committed — it's regenerated and checked in manually via node scripts/gen-active-redirects.mjs when the legacy redirect map changes, not on every build.)

The API reference section (docs/api/reference/, also gitignored) has the same requirement: docusaurus-plugin-openapi-docs needs docusaurus gen-api-docs mattermost run before it has any pages to render. prestart handles this too — using the existing OpenAPI spec if present, only falling back to the slow make -C api build spec rebuild if it's missing.

Full production build

The production build also includes an OpenAPI prebuild step (npm run build:openapi, wired to run automatically before npm run build via the same prebuild hook) that invokes make -C api build. This requires Go and takes ~2 minutes.

cd docs/site
npm ci
npm run build      # runs build:sidebars + build:openapi (via prebuild), then Docusaurus build

To skip the OpenAPI rebuild during iterative content work:

cd docs/site
npm run build -- --no-minify   # still runs build:sidebars + build:openapi first

If you need to bypass the prebuild step entirely (e.g., all generated artifacts already exist and are current), run:

cd docs/site
npm run docusaurus build       # calls docusaurus directly, skips prebuild

There's a single Algolia DocSearch app for docs.mattermost.com — credentials aren't distributed to individual developers. They're set as repository variables (vars.ALGOLIA_APP_ID, vars.ALGOLIA_SEARCH_API_KEY) and injected only in CI/CD. Local builds simply run without them: the site builds cleanly and the search bar is omitted (see the conditional in docusaurus.config.ts).

If you need to test search locally, export the same two variables in your shell before running npm start/npm run build.
