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

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

Ensure the project is linked. Check for .insforge/project.json in the project root.

Generate it with npx @insforge/cli link for an existing project or npx @insforge/cli create for a new project.

Get the anon key via the CLI:

npx @insforge/cli secrets get ANON_KEY

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

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:

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:

import { createClient } from '@insforge/sdk'

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

Vite:

import { createClient } from '@insforge/sdk'

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

Astro:

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:

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

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

Guides

Guide
When to Use

../insforge-cli/references/database/access-control.md
Backend setup for application-table access control — covers RLS, infinite recursion prevention, SECURITY DEFINER patterns, performance tips, and common InsForge patterns

storage/s3-gateway.md
Fallback path when the consumer is existing S3 tooling (aws CLI, AWS SDKs, rclone, Terraform, boto3) and adopting @insforge/sdk is impractical — covers endpoint/region setup, access-key management, path-style addressing, and supported vs. not-supported S3 operations. Requires InsForge 2.0.9+. Prefer the SDK (storage/sdk-integration.md) for app code

storage/postgres-rls.md
Writing RLS policies for storage.objects — owner-only, public-read, path-scoped, team-shared, and the NULL uploaded_by caveat for mixed REST + S3 buckets

../insforge-cli/references/database/vector.md
Backend setup for semantic search, recommendations, or RAG — covers the vector extension, schema/dimensions, distance operators, HNSW/IVFFlat indexes, and RPC similarity search

ai/chat-completions.md
Text generation, structured answers, and streaming chat through OpenRouter

ai/image-generation.md
Image generation/editing through OpenRouter, then durable storage in InsForge Storage

ai/video-generation.md

payments
Configuring Stripe/Razorpay keys, syncing provider catalog, setting up webhooks, and writing payment RLS before app integration

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.

For Razorpay Orders, Subscriptions, Checkout.js, and cancel/pause/resume flows, load payments/razorpay.md.

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

npx @insforge/cli payments stripe status
npx @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.

Backend Configuration

Supported project config knobs are managed via the CLI — use
npx @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 for the decision guide and lifecycle commands. Typical loop:

npx @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 @insforge/cli branch merge feat-x --dry-run     # review SQL
npx @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([{...}])

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

Storage: Save both url AND key to database for download/delete operations

Functions invoke URL: /functions/{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.

Payments: Configure provider keys/catalog with npx @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 @insforge/cli branch create first — see the insforge-cli skill's branch reference. After branch create / branch switch, update the app's InsForge URL and anon-key env values, then restart the dev server.
