`@zxcv.build/sdk`

A typed client, generated from your project’s schema. Queries, auth, storage, and realtime share one isomorphic library that runs in the browser and on the edge.

Install


npm i @zxcv.build/sdk

Initialize


import { createClient } from '@zxcv.build/sdk'
 
export const zxcv = createClient({
  project: 'acme-store',
  // The anon key is safe to ship — authorization is enforced server-side
  // by your .policy rules, not by the client.
  key: process.env.ZXCV_ANON_KEY!,
})

Query

Every table is typed from your schema, so select autocompletes columns and returns typed rows.


const { data, error } = await zxcv
  .from('reviews')
  .select('id, rating, body, author')
  .eq('product', productId)
  .order('created_at', { ascending: false })
  .limit(20)

Results are already filtered by authorization — the client only ever sees rows a policy granted.

Realtime


const channel = zxcv
  .from('reviews')
  .on('insert', (review) => addToUI(review))
  .subscribe()

The change feed honors the same policy predicate as select, so subscribers never receive a row they couldn’t read.
