@revinel/sdk

Universal headless SDK for fetching and tracking Revinel publisher ads. Zero dependencies; runs in any JS runtime with fetch (browser, Node, edge, workers).

Install

npm install @revinel/sdk

Usage

import { createRevinelClient } from "@revinel/sdk"

const revinel = createRevinelClient({
  workspaceId: "your-workspace-id",
  // apiUrl is optional — it defaults to the Revinel production API. Only set it
  // to point at a local/staging API in development.
})

// Fetch the single ad currently serving for a placement.
const ad = await revinel.getAd({ weightGte: 2.5 })

// Fetch several ads for a grid (rotation-aware; pass excludeIds to dedupe).
const ads = await revinel.getAds({ count: 5, excludeIds: ad ? [ad.id] : [] })

// Record events.
if (ad) {
  await revinel.recordImpression(ad.id)
  await revinel.recordClick(ad.id)
}

getAd resolves to RevinelAd | null; getAds to RevinelAd[] (empty when nothing is eligible — the SDK never throws on "no ads"). ad.faviconUrl is string | null.

Multiple slots on one page? Use a single getAds({ count: n }), not n × getAd(). Every getAd() sends the same request, so the shared edge cache hands back the same ad to each call — you'd render duplicates and record duplicate impressions. One getAds({ count }) returns n distinct ads in one round trip; pass excludeIds when you fetch further ads separately to keep dedupe across calls.

Fetch on the server. Ad fetching belongs in your server/edge code (RSC, loader, route handler) so the ad is server-rendered — no layout shift, no client waterfall. Reach for @revinel/react's useAd only in client-only apps.

Typed creative (meta)

ad.meta is keyed by each custom field's stable machine slug (set when the publisher creates the field, e.g. bannerImage for a "Banner image" field — visible in the Revinel dashboard). Register your creative shape once and every call is typed — no per-call generic, no cast:

// revinel.d.ts (or anywhere in your app)
declare module "@revinel/sdk" {
  interface RevinelMetaRegistry {
    tagline?: string
    description?: string
    bannerImage?: string
    ctaLabel?: string
  }
}

const ad = await revinel.getAd({ weightGte: 2.5 })
ad?.meta.bannerImage // string | undefined — fully typed

The slug is immutable, so renaming a field's display label never breaks your code. Each entry is also available in ad.fields as { key, name, type, value } if you need the human label. For a one-off shape (e.g. a multi-workspace app) you can still pass a generic: revinel.getAd<{ bannerImage?: string }>().

Next.js / caching

Ad fetches default to next: { revalidate: 60 }, so Next.js App Router pages that call getAd/getAds stay statically renderable while the ad still refreshes every minute (an explicit no-store would force the route dynamic and 500 statically-generated pages at runtime). Revinel's API edge-caches responses for ~5s anyway, so per-request rotation was always approximate. Non-Next runtimes ignore the next key: server fetches (Node/edge) stay uncached, while browsers honor the response Cache-Control (max-age=5) and may reuse an identical request for up to ~5s — the same window the API's edge cache already imposes. Opt out for true per-request rotation (on an already-dynamic Next page, or anywhere else):

const ad = await revinel.getAd({ request: { cache: "no-store" } })

Any explicit cache or next.revalidate replaces the default entirely.

Timeouts

Requests abort after 10 seconds by default (via AbortSignal.timeout), rejecting with a TimeoutError DOMException so a hung connection never stalls your renderer. Tune or disable it per client:

const revinel = createRevinelClient({ workspaceId: "…", timeoutMs: 5_000 }) // `false` disables

Errors

Non-2xx responses throw RevinelApiError ({ status, body }). The body is the Revinel API error envelope:

{ "defined": false, "code": "NOT_FOUND", "status": 404, "message": "Workspace not found." }

Input-validation failures use HTTP 422 with code: "INPUT_VALIDATION_FAILED" and a data.fieldErrors / data.formErrors map.
