Adding Activation to Next.js + LangChain + Supabase Apps

After users sign up with Next.js + LangChain + Supabase, there's no automated system to track their progress toward activation milestones.

Next.js + LangChain + Supabase

Last updated:

What's Missing in Standard Next.js + LangChain + Supabase Architecture

Supabase's Row Level Security and real-time features are great, but there's no built-in system to detect when users complete their first value milestone. You'd need to manually check user actions or set up complex PostgreSQL triggers. RLS policies can also block event tracking if not configured correctly.

Standard Next.js + LangChain + Supabase Flow vs Optimized Skene Flow

Standard Flow
1

User signs up via authentication

2

User record created in Supabase

3

No automatic trigger - manual follow-up required

Skene Flow
1

Watch Supabase 'users' table for new signups using supabase.from('table').select()

2

Detect when user completes first key action (e.g., creates first project) using Supabase queries

3

Trigger activation email sequence via Resend with personalized onboarding

4

Track activation completion and send milestone emails

How Skene Fixes This

This Skene Prompt installs activation detection into Next.js + LangChain + Supabase by watching Supabase tables for key user actions. When users complete their first value milestone, it triggers welcome sequences and feature discovery emails.

Implementation Comparison

Using Skene Infrastructure

Install via Prompt

cursor.mdc
@task: Initialize Skene.
@action: Analyze my local code, validating subscription via `npx skene login`, and generate `skene.config.ts` to implement the Activation Loop pattern for Next.js + LangChain + Supabase.

Copy Skene Prompt for Cursor

Generated skene.config.ts

skene.config.ts
// skene.config.ts - The Automated Way
import { defineLoop } from '@skene/sdk';

export default defineLoop({
  type: 'activation',
  opinion: 'Detect when users complete their first key action and trigger personalized onboarding',
  steps: [
    {
      trigger: {
        type: 'database',
        table: 'users',
        event: 'insert'
      },
      condition: {
        type: 'query',
        query: `SELECT * FROM user_actions WHERE user_id = $1 AND action_type = 'first_project_created'`,
        timeout: '5m'
      },
      action: {
        type: 'email',
        provider: 'resend',
        template: 'activation_welcome',
        personalization: {
          name: '{{user.name}}',
          activationLink: '{{user.activation_link}}'
        }
      }
    }
  ],
  recovery: {
    retries: 3,
    backoff: 'exponential'
  }
});
