Netlify Blobs
Modern syntax: import from @netlify/blobs, open a store, then call methods on the handle.
import { getStore, getDeployStore, listStores } from "@netlify/blobs";
import type { Context } from "@netlify/functions"; // or "@netlify/edge-functions"
In Functions, Edge Functions, and Build Plugins, siteID, deployID, token (and region for getDeployStore) are injected automatically. Install with npm install @netlify/blobs.
Not a database. For dynamic, per-user, transactional, or relational data, use Netlify DB. Blobs is for objects, files, and cache-like state. It is optimized for frequent reads and infrequent writes.
Store scope is a footgun. Read this first. getStore opens a site-wide store shared across ALL deploy contexts. Code on a deploy preview reads, overwrites, and deletes production data. Never run destructive tests or seed throwaway data from a preview against a site-wide store. Use getDeployStore() or a context-specific store name for isolation.
