name: instancez
description: Use when building, changing, or deploying an instancez backend - editing instancez.yaml (tables, RLS, auth, storage, rpc, functions), running the inz CLI, or debugging why a query is denied. instancez is a single-binary Supabase-compatible backend defined by one YAML file.

# Building with instancez

instancez turns one file, `instancez.yaml`, into a full backend: Postgres CRUD, auth, storage, SQL RPC, and Node.js functions. Clients talk to it with `@supabase/supabase-js` (or any Supabase client library) unchanged. There are no migration files: on every run the migrator diffs the YAML against the live database and applies the delta, including drops.

## Workflow

If `inz` is not installed: `curl -fsSL https://get.instancez.ai | sh` (macOS/Linux) or `irm https://get.instancez.ai/windows | iex` (PowerShell).

```sh
inz init                # scaffold instancez.yaml + .development.env.example
inz validate            # check YAML syntax and references, no DB needed
inz dev --embedded-pg   # dev server on :8080 with a built-in Postgres 16
```

`instancez.yaml` starts with `# yaml-language-server: $schema=https://docs.instancez.ai/schema/instancez.json`; keep it for editor completion.

Edit `instancez.yaml`, save, and `inz dev` re-applies the schema automatically. Always run `inz validate` after editing the YAML; it catches bad types, bad references, and missing function files without touching a database.

Without `--embedded-pg`, `inz dev` needs `INSTANCEZ_DATABASE_URL` set to a superuser DSN. API keys land in `.development.env` on first run (`INSTANCEZ_PUBLISHABLE_KEY`, `INSTANCEZ_SECRET_KEY`). `inz doctor` diagnoses a dev setup that won't boot. The banner prints the embedded DB URL.

For typed queries, run `inz gen types --out database.types.ts` and pass the result to `createClient<Database>()`. It reads only the YAML; regenerate after schema changes.

Client-side, the app is a normal Supabase app. Point any Supabase client library at the server and the whole surface works: PostgREST-style queries with filters and embeds, auth, storage, RPC, functions.

```js
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('http://localhost:8080', process.env.INSTANCEZ_PUBLISHABLE_KEY)
const { data, error } = await supabase.from('todos').select('*').eq('status', 'pending')
```

The secret key takes the `service_role` path (bypasses RLS); keep it server-side only.

Other commands: `inz serve` (production, no hot reload, dashboard off by default), `inz bundle` (build a tar.gz of config + functions for deploys), `inz cloud deploy` (push to a managed project; `--new` creates one), `inz db reset` (wipe the local DB; `--embedded-pg` for ./pgdata).
