Every component has a stable slug, a type (`json`, `text`, or `file`), a per-component cache TTL, and an auto-incrementing version number that becomes its HTTP `ETag`. Subscribers fetch the latest version on demand and revalidate cheaply with `304 Not Modified` for unchanged content. A single site can also act as **both** Host and Receiver — publish your own Library while subscribing to one or more remote Hosts. #### Use cases * Keep brand assets (logo, favicon, tagline, contact info) in sync across a fleet of WordPress sites without copy-paste. * Centralise structured data (footer links, locations, pricing tables) so updating once propagates everywhere. * Serve component content from a dedicated CDN subdomain via a thin reverse-proxy layer. * Pull versioned content into a headless frontend (Next.js, Astro, Vercel) with stable cache semantics. #### Key features * **Three component types** — JSON, plain text, and file (proxies URLs through the REST endpoint). * **Two independent capabilities** — publish your Library and/or subscribe to a remote Host. Toggle each side on or off in Settings. * **HTTP cache headers** — every `/raw` response sends `ETag`, `Last-Modified`, and `Cache-Control: public, max-age=, must-revalidate`. Conditional requests get `304 Not Modified`. * **Per-IP rate limiting** — 120 requests per 60 seconds on the host endpoints. * **CORS control** — open, allowlist, or denylist by domain (with `*.example.com` wildcard support). * **Optional authentication** — require Application Passwords on either side independently. * **Source connection tester** — verify a Host URL from the Settings page before saving. * **Native admin UI** — built on WordPress admin patterns, fully translatable. #### REST endpoints (Host mode) * `GET /wp-json/wp-components/v1/components` — list all published components * `GET /wp-json/wp-components/v1/components/{slug}` — fetch one as JSON metadata * `GET /wp-json/wp-components/v1/components/{slug}/raw` — fetch with type-appropriate` Content-Type` (text/plain, application/json, or proxied file bytes) ## Installation 1. Install the plugin from **Plugins Add New** and search for _Artificial Poets Reusable Components CDN_, or upload the `.zip` via **Plugins Add New Upload Plugin**. 2. Activate **Artificial Poets Reusable Components CDN** under **Plugins Installed Plugins**. 3. Open **Components** in the admin menu; the onboarding screen asks how you want this site to participate. 4. **Publish only** to expose a Library via REST. **Subscribe only** to pull from another Host. **Both** to do both. 5. If subscribing, enter the Host URL under **Components Settings Source Subscription** and click _Test Connection_. ## FAQ ### Does this work for headless WordPress / Next.js / Astro frontends? Yes. The Host’s `/wp-json/wp-components/v1/components/{slug}/raw` endpoint returns the content with the right `Content-Type` header and proper `Cache-Control` / `ETag`, so a frontend can `fetch()` it directly. For images, an `` works without any client-side glue. ### Can one site be both Host and Receiver? Yes. Set **Publish Library** and **Subscribe to Source** both ON in Settings. You’ll see your own Library and the remote Source in separate tabs in the admin menu. ### How is the cache invalidated when I update a component? Every save bumps the component’s version, which is also the `ETag`. The next request from a subscriber gets a fresh response; subsequent requests with `If-None-Match` get a fast `304 Not Modified`. ### Does the plugin require an external service? No. All data stays on your own WordPress sites. There are no calls to third-party servers, no telemetry, no SaaS dependencies. ### Can I require authentication between Host and Receiver? Yes. On the Host: **Components Settings Library Publishing Access** can require an Application Password. On the Receiver: **Settings Source Subscription Authentication** lets you send Application Password credentials when fetching. ### What does it cost? Nothing. The plugin is GPL-2.0-or-later and free to use commercially. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Artificial Poets Reusable Components CDN” is open source software.
