The data layer ships a second time as a REST layer: templates/shared/rest/ (the auth seam client.ts, media.ts, config.ts) and templates/<vertical>/rest/ (the same exports as the vertical’s app/wix/<vertical>/ data layer, over fetch), typed against the same types.ts and importing the same *-core.ts rule files as the SDK layer — one implementation of the rules, two transports. The vertical’s INSTRUCTIONS.md names its modules and what each surface does with them; this section is the mechanics, the same for every vertical. The site-search capability (templates/shared/capabilities/site-search/, on from plan.capabilities.siteSearch) has the same two transports: with --plan its REST twin and stores land in js/wix/ beside the vertical’s (search.js, search-store.js, suggest-store.js), and its INSTRUCTIONS.md applies.

• Static site (no bundler). Step 3’s setup with --stack static runs init in the project folder (site, OAuth app, wix.config.json), points site.outputDirectory at "./site", and runs deploy.mjs <vertical> --stack static --out site, which composes the REST layer and the vertical’s framework-free stores flat into site/js/wix/ and strips them to browser ESM (comments kept, the .ts kept beside the .js to read). The site lives in that subfolder, site/, holding only the pages, styles, assets and js/: wix release uploads it whole, so the project root (config, plan.json, seed output, the skills) must not be it; move the pages in. (On a project that already has its config, the same deploy.mjs call does the deploy.) Pages import the vertical’s modules from ./js/wix/ in a <script type="module">: the stores hold the state machines (subscribe, render from getState(), call actions), the page holds the rendering. The visitor token lives in localStorage and is the visitor’s identity across Wix — never mint one per page. A route is a page plus a query-string slug (item.html?slug=…). Wix static hosting serves files, not directories: /shop does not resolve to shop/index.html, and there is no routes configuration — name the file and link to it. Seed per the vertical’s SEED.md (Node + the CLI token, no project dependencies). Release with npx @wix/cli@latest release — no build. Item-page tags come from the entity’s seoData, set after the fetch (document.title, the meta description).
• A dropped site on its Wix Dev Machine (shape static-in-astro). The machine holds the dropped pages in public/ of an Astro starter with no pages of its own, and its Astro config redirects / to /index.html. The pages stay where they are: run deploy.mjs <vertical> --stack static --out public, which writes public/js/wix/, and wire the pages in place as above. The config is left as it is, so the release goes through Astro: npx @wix/cli@latest build && npx @wix/cli@latest release, to the same URL.
• Server-rendered, another language (Flask, Laravel, Rails, …). The same shape as managed Astro — pages rendered on the server, the interactive surfaces in the browser — with hosting and SEO plumbing theirs. init still runs in the project folder; run deploy.mjs <vertical> --stack static there too: it only needs wix.config.json and writes js/wix/. Split by where the call runs:
  • Reads render on the server. Port the vertical’s rest/ read module and its *-core.ts to the server language: each function is one HTTP call with a literal URL and JSON body, and the core carries the rules. That code is tested and proven against live sites — carry its bodies over as they are, fields arrays and filter keys included (they are not guessable, and a near-miss returns empty or unformatted data with no error), and render what Wix returns (formattedAmount, never a number you format yourself). The shipped JS runs: when in doubt, run the module with Node against the same site and compare one entity with your port. Public reads need no visitor identity — one anonymous visitor token per server process, refreshed per client.ts, is enough for them.
  • Visitor-specific state runs in the browser. Whatever the vertical does on the visitor’s behalf (a store’s cart and checkout, a booking, an RSVP, a form submit) loads the vertical’s js/wix/ module in the templates and talks to Wix from the page, exactly as a static site does: the browser owns the visitor token in localStorage, so the server handles no per-visitor tokens. If that state must run server-side anyway, client.ts‘s header applies: one token set per visitor in the visitor’s session, never one process-wide token (that is one identity shared by everyone).
  • A Wix-hosted flow returns to the origin that started it, and only to one it knows. Checkout, a booking payment, a plan purchase all open on Wix and come back to your server; the return works only for an origin on the site’s OAuth app allow-list. Add the server’s origin — the dev one while verifying (http://localhost:<port>), the public https one when it goes live — before the first checkout test: wix-manage’s Manage OAuth Apps recipe, “Update an OAuth App”, field allowedRedirectDomains, on the app whose id is appId in wix.config.json. Without it the Wix page opens and cannot return. Do it; do not only say it.
  • Pre-rendered → Wix-hosted. If the project builds to static HTML (Frozen-Flask, Pelican, Hugo, Eleventy, any static-site generator), Wix can host the output: run deploy.mjs <vertical> --stack static --out <build dir> so js/wix/ lands inside the build output (or copy it there after each build), make the generator emit a page for every entity slug the vertical’s list read returns (walk it by cursor, never only the first page), point site.outputDirectory at the build folder, wix release. The build’s own reads use one anonymous visitor token for the duration of the build. What Wix hosts is exactly the contents of that folder after your last build, served as files: every asset a page references must be in there and current — if the pipeline has more than one build step (templates, then a CSS or asset bundle), they all run, in order, on every rebuild, or the release carries a stale piece. a clean path does not resolve to a folder’s ; name the file and link to it. Generated pages sit at different depths, so reference through one base path (a template variable, or root-relative ), never — a relative path breaks one level down. : the vertical’s interactive behaviour (a store’s sort, filters, and cart; a blog’s search; a booking flow) still runs client-side on top of it from the same modules, so the vertical’s surface contracts in apply unchanged. Close with the rebuild + release command and one line for the owner: content edits made in the dashboard reach the site when that command runs; the browser-side flows are live regardless. A running server (live reads on every request) stays theirs to host. Then read the vertical’s for the surfaces and hard rules, and the shared /. — its lists which files and what to take from each. They don’t deploy on this stack, and they are working, tested code for exactly the behaviour you are about to write in your own; rewriting them from prose is where the bugs come from (the runs that skipped them shipped a broken quick-add, the run that read them didn’t). Both were written for the stacks that receive the code, so they speak that stack’s dialect: the Tailwind classes in the skeletons and the components are one spelling of layout and behaviour rules that hold everywhere (a bounded image band on phones, name and price on separate lines, the buy control pinned to the tile’s bottom, an overlay that locks scroll and returns focus). Take the rules; write them in the CSS your stack uses, on a token set you define — nothing here asks you to add Tailwind. Close with run (or rebuild) instructions, the live URL when Wix hosts the output, the dashboard link, and — when hosting is theirs — which origins are on the OAuth app’s allow-list and that the public one must be added when the server moves (the step above).
• Both: the calls in rest/ are the ones a visitor token may make from a page — public reads and the visitor’s own actions. Anything elevated (writes to content, other people’s data) runs server-side per templates/shared/CUSTOM_OPERATIONS.md; the seed’s CLI token never belongs in a page. A static site has no SSR; neither case has owner-editable item-page SEO through @wix/seo (tags come from the entity’s seoData) — say so in the closing message; managed Astro stays the recommendation for a public site.
