Download the latest version for your platform:

• Node.js: >= 20.0.0
• MongoDB: Running locally or accessible remotely
• Git: For cloning the repository

1. Clone the repository

git clone https://github.com/trueleaf/apiflow.git
cd apiflow

2. Install dependencies

npm install
# or
npm run bootstrap

This will install dependencies for both packages/web and packages/server.

3. Configure environment variables

Create or edit configuration files in packages/server/src/config/ as needed.

4. Start development servers

npm run dev

This command will start both the frontend and backend servers concurrently:

• Frontend (Web): http://localhost:4000
• Backend (Server): http://localhost:7001

This is a multi-package monorepo:

• packages/web - Frontend application (Vite + Vue 3 + Electron)
• packages/server - Backend application (Midway.js + MongoDB)
• packages/website - Marketing website (Next.js)

• Ensure MongoDB is running before starting the server
• The frontend supports hot module replacement (HMR) for fast development
• Backend auto-restarts when files change
• You can develop packages independently by running their specific dev commands

• Docker
• Docker Compose

git clone https://github.com/trueleaf/apiflow
cd apiflow

cp .env.example .env
# edit .env to configure MongoDB credentials

docker compose pull
docker compose up -d

# Verify deployment
curl http://localhost  
curl http://localhost/api/health 

If you are running Apiflow with Docker, updating the code does not require rebuilding locally.

Simply pull the latest images and restart the services:

docker compose pull
docker compose up -d
