Insforge

Use this skill whenever writing frontend code that talks to a backend for database queries, authentication, file uploads, AI features, real-time messaging, or edge function calls — especially if the project uses InsForge or @insforge/sdk. Trigger on any of these contexts: querying/inserting/updating/deleting database rows from frontend code, adding login/signup/OAuth/password-reset flows, uploading or downloading files to storage, invoking serverless functions, calling AI chat completions or image generation, subscribing to real-time WebSocket channels, or writing RLS policies. If the user asks for these features generically (e.g., "add auth to my React app", "fetch data from my database", "upload files") and you're unsure whether they use InsForge, consult this skill and ask. For backend infrastructure (creating tables via SQL, deploying functions, CLI commands), use insforge-cli instead.

InsForge SDK 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, website deployments, cron job and schedules, logs, etc.), use the insforge-cli skill.

Quick Setup

npm install @insforge/sdk@latest

import { createClient } from '@insforge/sdk'

const insforge = createClient({
  baseUrl: 'https://your-project.region.insforge.app',
  anonKey: 'your-anon-key'
})

Real-time Configuration

For real-time channels and database triggers, use insforge db query with SQL to create triggers that publish to channels. The real-time SDK is for frontend event handling and messaging, not backend configuration.

Create Database Triggers

Automatically publish events when database records change.

-- Create trigger function
CREATE OR REPLACE FUNCTION notify_order_changes()
RETURNS TRIGGER AS $$
BEGIN
  PERFORM realtime.publish(
    'order:' || NEW.id::text,    -- channel
    TG_OP || '_order',           -- event: INSERT_order, UPDATE_order
    jsonb_build_object(
      'id', NEW.id,
      'status', NEW.status,
      'total', NEW.total
    )
  );
  RETURN NEW;
END;
$$ LANGUAGE plpgsql SECURITY DEFINER;

-- Attach to table
CREATE TRIGGER order_realtime
  AFTER INSERT OR UPDATE ON orders
  FOR EACH ROW
  EXECUTE FUNCTION notify_order_changes();

Conditional Trigger (Status Changes Only)

CREATE OR REPLACE FUNCTION notify_order_status()
RETURNS TRIGGER AS $$
BEGIN
  PERFORM realtime.publish(
    'order:' || NEW.id::text,
    'status_changed',
    jsonb_build_object('id', NEW.id, 'status', NEW.status)
  );
  RETURN NEW;
END;
$$ LANGUAGE plpgsql SECURITY DEFINER;

CREATE TRIGGER order_status_trigger
  AFTER UPDATE ON orders
  FOR EACH ROW
  WHEN (OLD.status IS DISTINCT FROM NEW.status)
  EXECUTE FUNCTION notify_order_status();

Access Control (RLS)

RLS is disabled by default. To restrict channel access:

• Enable RLS

ALTER TABLE realtime.channels ENABLE ROW LEVEL SECURITY;
ALTER TABLE realtime.messages ENABLE ROW LEVEL SECURITY;

• Restrict Subscribe (SELECT on channels)

CREATE POLICY "users_subscribe_own_orders"
ON realtime.channels FOR SELECT
TO authenticated
USING (
  pattern = 'order:%'
  AND EXISTS (
    SELECT 1 FROM orders
    WHERE id = NULLIF(split_part(realtime.channel_name(), ':', 2), '')::uuid
      AND user_id = auth.uid()
  )
);

• Restrict Publish (INSERT on messages)

CREATE POLICY "members_publish_chat"
ON realtime.messages FOR INSERT
TO authenticated
WITH CHECK (
  channel_name LIKE 'chat:%'
  AND EXISTS (
    SELECT 1 FROM chat_members
    WHERE room_id = NULLIF(split_part(channel_name, ':', 2), '')::uuid
      AND user_id = auth.uid()
  )
);

• Quick Reference

Task	SQL
Create channel	INSERT INTO realtime.channels (pattern, description, enabled) VALUES (...)
Create trigger	CREATE TRIGGER ... EXECUTE FUNCTION ...
Publish from SQL	PERFORM realtime.publish(channel, event, payload)
Enable RLS	ALTER TABLE realtime.channels ENABLE ROW LEVEL SECURITY

Best Practices

1. Create channel patterns first before subscribing from frontend

   • Insert channel patterns into realtime.channels table
   • Ensure enabled is set to true

2. Use specific channel patterns

   • Use wildcard % patterns for dynamic channels (e.g., order:% for order:123)
   • Use exact patterns for global channels (e.g., notifications)

Common Mistakes

Mistake	Solution
Subscribing to undefined channel pattern	Create channel pattern in realtime.channels first
Channel not receiving messages	Ensure channel enabled is true
Publishing without trigger	Create database trigger to auto-publish on changes

Recommended Workflow

1. Create channel patterns   → INSERT INTO realtime.channels
2. Ensure enabled = true     → Set enabled to true
3. Create triggers if needed → Auto-publish on database changes
4. Proceed with SDK subscribe → Use channel name matching pattern

Backend Configuration (Not Yet in CLI)

These modules still require HTTP API calls because the CLI does not yet support them:

Module	Backend Configuration
Auth	auth/backend-configuration.md
AI	ai/backend-configuration.md

SDK Quick Reference

All SDK methods return { data, error }.

Module	Methods
insforge.database	.from().select(), .insert(), .update(), .delete(), .rpc()
insforge.auth	.signUp(), .signInWithPassword(), .signInWithOAuth(), .signOut(), .getCurrentSession()
insforge.storage	.from().upload(), .uploadAuto(), .download(), .remove()
insforge.functions	.invoke()
insforge.ai	.chat.completions.create(), .images.generate(), .embeddings.create()
insforge.realtime	.connect(), .subscribe(), .publish(), .on(), .disconnect()

Important Notes

• Database inserts require array format: insert([{...}]) not insert({...})
• Storage: Save both url AND key to database for download/delete operations
• Functions invoke URL: /functions/{slug} (without /api prefix)
• Use Tailwind CSS v3.4 (do not upgrade to v4)
• Always local build before deploy: Prevents wasted build resources and faster debugging
