# Base44 → AWS

> Step-by-step guide to migrating your Base44 app to production on AWS.

This guide walks you through migrating a Base44 app to a production AWS deployment with your own domain, database, and Git history.

## What gets migrated

* Full React + Vite source code
* Supabase database schema (tables, indexes, RLS policies)
* All detected environment variables
* Static assets and public files

## Prerequisites

* An Nometria account
* The [Nometria Chrome Extension](https://nometria.com/extension) installed
* Your Base44 project open in Chrome
* A custom domain (optional — a free `*.nometria.com` URL is provided if not)
* A Supabase account (free tier works)

## Step 1 — Export from Base44

<Steps>
  <Step title="Open your Base44 project">
    Navigate to your Base44 project. Make sure you're on the main editor view (not the settings or billing pages).
  </Step>

  <Step title="Click Export in the extension">
    Click the Nometria extension icon in your Chrome toolbar → **Export to Nometria**.

    The extension reads your project's file tree. You'll see a progress indicator as it packages the code.
  </Step>

  <Step title="Review the detected stack">
    A preview shows:

    * Framework: React + Vite
    * Database: Supabase (with your project ID)
    * File count and estimated size

    Confirm and click **Continue to Nometria**.
  </Step>
</Steps>

## Step 2 — Configure your deployment

You'll land on the Nometria configuration screen with your Base44 project pre-loaded.

<Steps>
  <Step title="Set environment variables">
    Nometria pre-fills variables detected from your Base44 project. Review them and add any missing values:

    ```bash theme={null}
    VITE_SUPABASE_URL=https://xxxxxxxxxxxx.supabase.co
    VITE_SUPABASE_ANON_KEY=eyJ...
    ```

    Add any additional API keys your app uses (Stripe, OpenAI, Resend, etc.).
  </Step>

  <Step title="Configure your database">
    Choose one of:

    **Option A — Migrate to your own Supabase project (recommended):**
    Select **Create new Supabase project**. Nometria provisions a Supabase project and migrates your Base44 schema automatically.

    **Option B — Keep using the Base44 Supabase project:**
    Select **Use existing Supabase project** and paste your Base44 project URL and service role key.

    <Warning>If you choose Option B, your data still lives in Base44's infrastructure. Option A gives you full ownership.</Warning>
  </Step>

  <Step title="Set your domain">
    Enter your custom domain or leave blank to use the free `*.nometria.com` staging URL.
  </Step>

  <Step title="Choose your AWS region">
    Select the region closest to your users. `us-east-1` is the default.
  </Step>
</Steps>

## Step 3 — Deploy

Click **Deploy**. Deployment takes 5–10 minutes on first run. You can watch build logs stream in real time.

When complete, your dashboard shows:

* Live URL (your domain or `*.nometria.com`)
* Git repository link
* Deployment timestamp and commit SHA

## Step 4 — Verify your app

Open your live URL and test:

* [ ] App loads correctly
* [ ] Authentication works (sign up / sign in)
* [ ] Database reads and writes work
* [ ] Any third-party integrations function (Stripe, email, etc.)

## Step 5 — Enable two-way sync (optional)

To keep iterating in Base44 and have changes flow to production automatically:

Settings → Sync → **Enable Two-Way Sync**

From now on, every code change in Base44 is committed to `builder/latest` and can be reviewed and merged to production without re-running the export flow.

## Post-migration checklist

* [ ] DNS is pointing to your Nometria deployment
* [ ] SSL certificate is active (green padlock)
* [ ] Supabase RLS policies are correct on the new project
* [ ] Old Base44 project is archived or deleted
* [ ] Environment variables are all set (no fallback to Base44 defaults)
