  Use this skill when writing app code with InsForge or @insforge/sdk: database CRUD, auth, storage uploads/storage RLS, functions, OpenRouter AI, realtime, emails, Stripe or Razorpay payments, or pointing S3-compatible tooling (aws CLI, AWS SDKs, rclone, Terraform, boto3) at InsForge Storage. Trigger on requests like add auth, fetch data, upload files, make a bucket public, add checkout, sell subscriptions, or send email. For infrastructure, SQL migrations, CLI commands, or payment provider setup, use insforge-cli instead.

# InsForge App Integration Skill

This skill covers **client-side SDK integration** using `@insforge/sdk`. For backend infrastructure operations (creating tables, inspecting schema, deploying functions, secrets, managing storage buckets, configuring payment provider keys/catalog, website deployments, cron job and schedules, logs, etc.), use the **insforge-cli** skill.

## Quick Setup

### 1. Install the SDK

```bash
npm install @insforge/sdk@latest
```

### 2. Set up environment variables

Before using the SDK, create a `.env` file (or `.env.local` for Next.js) in your project root with your InsForge URL and anon key.

#### How to get your URL and anon key

1. **Ensure the project is linked.** Check for `.insforge/project.json` in the project root.
   - Generate it with `npx -y @insforge/cli link` for an existing project or `npx -y @insforge/cli create` for a new project.

2. **Get the anon key** via the CLI:

   ```bash
   npx -y @insforge/cli secrets get ANON_KEY
   ```

3. **Get the URL** from the `oss_host` field in `.insforge/project.json` (e.g., `https://myapp.us-east.insforge.app`).

4. **Write both values** to the `.env` file using the correct framework prefix (see table below).

> **Important:** Use the anon key for user-scoped SDK clients, including SSR. For privileged server-only app code that needs admin/service access, use `createAdminClient({ apiKey })`; the API key is a full-access admin key, equivalent to a service role key on other platforms.

Use the correct environment variable prefix and access pattern for your framework:

| Framework                     | `.env` file  | Variables                                                   | Access Pattern                              |
| ----------------------------- | ------------ | ----------------------------------------------------------- | ------------------------------------------- |
| **Next.js**                   | `.env.local` | `NEXT_PUBLIC_INSFORGE_URL`, `NEXT_PUBLIC_INSFORGE_ANON_KEY` | `process.env.NEXT_PUBLIC_*`                 |
| **Vite** (React, Vue, Svelte) | `.env`       | `VITE_INSFORGE_URL`, `VITE_INSFORGE_ANON_KEY`               | `import.meta.env.VITE_*`                    |
| **Astro**                     | `.env`       | `PUBLIC_INSFORGE_URL`, `PUBLIC_INSFORGE_ANON_KEY`           | `import.meta.env.PUBLIC_*`                  |
| **SvelteKit**                 | `.env`       | `PUBLIC_INSFORGE_URL`, `PUBLIC_INSFORGE_ANON_KEY`           | `import { env } from '$env/dynamic/public'` |
| **Create React App**          | `.env`       | `REACT_APP_INSFORGE_URL`, `REACT_APP_INSFORGE_ANON_KEY`     | `process.env.REACT_APP_*`                   |
| **Node.js / Server**          | `.env`       | `INSFORGE_URL`, `INSFORGE_ANON_KEY`                         | `process.env.*`                             |

Example `.env.local` for Next.js:

```bash
NEXT_PUBLIC_INSFORGE_URL=https://your-appkey.us-east.insforge.app
NEXT_PUBLIC_INSFORGE_ANON_KEY=eyJhbGciOiJIUzI1NiIs...
```

> **Important:** Keep `.env` files local. Add `.env`, `.env.local`, and `.env*.local` to your `.gitignore` and keep `.env.example` for documenting required variables.

### 3. Initialize the client

Next.js:

```javascript
import { createClient } from '@insforge/sdk'

const insforge = createClient({
  baseUrl: process.env.NEXT_PUBLIC_INSFORGE_URL,
  anonKey: process.env.NEXT_PUBLIC_INSFORGE_ANON_KEY
})
```

Vite:

```javascript
import { createClient } from '@insforge/sdk'

const insforge = createClient({
  baseUrl: import.meta.env.VITE_INSFORGE_URL,
  anonKey: import.meta.env.VITE_INSFORGE_ANON_KEY
})
```

Astro:

```javascript
import { createClient } from '@insforge/sdk'

const insforge = createClient({
  baseUrl: import.meta.env.PUBLIC_INSFORGE_URL,
  anonKey: import.meta.env.PUBLIC_INSFORGE_ANON_KEY
})
```

For trusted server-only code that needs project-admin access:

```javascript
import { createAdminClient } from "@insforge/sdk";

const admin = createAdminClient({
  baseUrl: process.env.INSFORGE_URL,
  apiKey: process.env.INSFORGE_API_KEY,
});
```

### Building Payments for a New App

First choose the provider. There is no generic app payments guide:

- For Stripe Checkout, subscriptions, and Billing Portal, load [payments/stripe.md](payments/stripe.md).
- For Razorpay Orders, Subscriptions, Checkout.js, and cancel/pause/resume flows, load [payments/razorpay.md](payments/razorpay.md).

Before writing app code, check provider setup with the **insforge-cli** payments references:

```bash
npx -y @insforge/cli payments stripe status
npx -y @insforge/cli payments razorpay status
```

If the chosen provider is unconfigured, ask the developer/admin to configure that provider first.

### Real-time Backend Setup

The real-time SDK is for frontend event handling and messaging. Configure channel patterns, database triggers, and channel/message RLS with the **insforge-cli** skill; see [realtime](../insforge-cli/references/realtime.md).

### Backend Configuration

Supported project config knobs are managed via the CLI — use
`npx -y @insforge/cli config export/plan/apply` for auth redirect URLs,
verification flags, password policy, auth SMTP settings, storage upload size,
realtime/schedule retention, and cloud deployment subdomain. OAuth providers,
external app setup, storage buckets, functions, secrets, and deployment env vars
still use their dedicated dashboard or CLI flows. See the **insforge-cli**
skill's Configuration section.

### Risky backend changes? Use a branch first

When a code change in this skill depends on a **schema migration**, **new RLS policy**, **OAuth provider config change**, or any other backend change that affects prod behavior, create a backend branch first. Branches share `JWT_SECRET` (existing user JWTs keep working) but get a fresh database + EC2 + `API_KEY` / `ANON_KEY`, so you can test the SDK + backend change end-to-end in isolation.

The full branching workflow lives in the **insforge-cli** skill — see [branch](../insforge-cli/references/branch/overview.md) for the decision guide and lifecycle commands. Typical loop:

```bash
npx -y @insforge/cli branch create feat-x --mode schema-only
# ... apply migrations / change auth config / update RLS on the branch ...
# ... test the SDK against the branch backend ...
npx -y @insforge/cli branch merge feat-x --dry-run     # review SQL
npx -y @insforge/cli branch merge feat-x               # apply to parent
```

> ⚠ **After `branch create` or `branch switch`**, update the app's InsForge URL and anon-key env values, then **restart your dev server** (or re-source `.env`) so the SDK talks to the selected branch backend.

## Important Notes

- **Database inserts require array format**: `insert([{...}])`
- **Bandwidth-efficient reads**: Name columns and `.limit()` list reads; never poll unbounded `select()` on an interval — subscribe with realtime (paired with a `realtime.publish` trigger) or poll a cheap ordered probe instead. Wasteful query shapes are the top cause of projects exhausting their monthly egress allowance. Probe snippet and full rules: [database/sdk-integration.md](database/sdk-integration.md#bandwidth-efficient-reads).
- **Next.js / SSR auth**: Use `@insforge/sdk/ssr` helpers (`createBrowserClient`, `createServerClient`, `createAuthActions`, `createRefreshAuthRouter`) and import `updateSession` from `@insforge/sdk/ssr/middleware` in Proxy/Middleware. Keep the refresh token httpOnly, run auth mutations through `createAuthActions()` on the server, return only safe app data from Server Actions, and let the browser read the short-lived access token for Storage/Realtime. See [auth/ssr-integration.md](auth/ssr-integration.md)
- **Storage**: Save both `url` AND `key` to database for download/delete operations
- **Functions invoke URL**: Prefer `insforge.functions.invoke(slug)` — the SDK owns route construction. For raw HTTP: the project base URL serves the compat path `/functions/{slug}`, while the functions deployment host (e.g. `*.function2.insforge.app`) serves the slug at root `/{slug}`
- **Email delivery**: Auth emails (signup verification, password reset, magic links, invites) ship on **every plan**. Custom email via `insforge.emails.send()` ships on **every paid plan**. Use the platform-managed delivery path; custom sender domain is dashboard config. See [email/sdk-integration.md](email/sdk-integration.md).
- **Payments**: Configure provider keys/catalog with `npx -y @insforge/cli payments <provider> ...` first; frontend code uses provider-scoped SDK modules.
- **Payment RLS**: Before payment UI, add app-specific RLS on provider runtime tables. Stripe uses `payments.stripe_checkout_sessions` and `payments.stripe_customer_portal_sessions`; Razorpay uses `payments.razorpay_orders` and `payments.razorpay_subscriptions`. Durable fulfillment triggers go on `payments.webhook_events`, not success URLs, Checkout callbacks, or `payments.transactions`.
- **Use Tailwind CSS v3.4**
- **Always local build before deploy**: Prevents wasted build resources and faster debugging
- **SDK package**: Use `@insforge/sdk` directly for all features including authentication.
- **Deployment**: Include a `vercel.json` in the project root for SPA routing (React, React Router apps). The `download-template` tool includes this automatically.
- **Branching for risky backend changes**: If your SDK code depends on a new schema, RLS policy, or auth config change, create a branch via `npx -y @insforge/cli branch create` first — see the **insforge-cli** skill's [branch](../insforge-cli/references/branch/overview.md) reference. After `branch create` / `branch switch`, update the app's InsForge URL and anon-key env values, then **restart the dev server**.
- **Hit an InsForge-side hurdle?** When the SDK, backend, docs, or a skill misbehaves — an API that should work but errors (`--type bug`), a capability you need that isn't supported (`--type feature-request`), docs that contradict actual behavior (`--type bug --component docs` with `--doc`/`--expected`) — report it and continue with a workaround: `npx -y @insforge/cli feedback --json --type <bug|feature-request|friction> --component <backend|sdk|cli|skills|docs> --title "..." --detail "..."`, adding `--language <lang>` for SDK issues (no login required; PII is redacted locally). See the **insforge-cli** skill's Feedback section for the full flag set and situation→type mapping. Never file feedback for problems in the app code you are writing.
