Local Development

Run Remix Studio on your own machine with npm run dev, backed by local PostgreSQL and MinIO from Docker Compose.

Requirements

• Node.js 20+
• Docker with Docker Compose, for running local PostgreSQL and MinIO
• At least one provider API key

1. Clone the Repository

git clone https://github.com/ShinChven/remix-studio.git
cd remix-studio

2. Start Local Services

docker compose up -d postgres minio

This starts PostgreSQL on 5432 and MinIO on 9000 with the console on 9001.

3. Install Dependencies

npm install

4. Configure Environment Variables

cp .env.example .env

.env.example is for host-based local development, where the app runs with npm run dev on your machine instead of inside Docker Compose.

If you run npm run dev on your host machine, point storage at the host-published MinIO port:

S3_ENDPOINT=http://localhost:9000

WARNING

Use http://minio:9000 only when the app itself is running inside Docker Compose on the same Docker network.

You should set at least these variables (see the full Configuration Reference):

• DATABASE_URL
• S3_ENDPOINT
• S3_ACCESS_KEY_ID
• S3_SECRET_ACCESS_KEY
• S3_BUCKET
• S3_EXPORT_BUCKET
• AWS_REGION
• PROVIDER_ENCRYPTION_KEY
• JWT_SECRET
• DEFAULT_ADMIN_EMAIL
• DEFAULT_ADMIN_PASSWORD

PROVIDER_ENCRYPTION_KEY must be stable

PROVIDER_ENCRYPTION_KEY must be a 64-character hex string. Do not change it after providers have been created unless you are also re-encrypting the stored provider credentials — existing provider API keys are encrypted with this value, and changing it later can make saved credentials unreadable.

If you previously ran an older version with a longer key value, the app may have been using only the first 64 hex characters. Keep that same effective 64-character value when upgrading.

Generate an encryption key with:

node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

5. Run Database Migrations

For a brand new local development database, run:

npx prisma migrate dev

If the database already exists and you only want to apply committed migrations safely, run:

npx prisma migrate deploy

Use migrate deploy when pulling new changes into an existing environment. migrate dev is intended for development workflows that create or reconcile migrations and may prompt for a reset when the database history has drifted.

6. Start the App

npm run dev

The app runs at http://localhost:3000.

NPM Scripts

Script	Purpose
npm run dev	Start the development server
npm run build	Build frontend and server bundles
npm run start	Run the production server from the built output
npm run lint	Run TypeScript type checking
npm run i18n:check	Compare translation completeness across locales
npm run mcp:inspect	Launch the MCP inspector against http://localhost:3000/mcp
