Technical stack for generating before-after map (with vector tiles), which allows users to understand how map data in OSM has changed over time.

# Installation and Setup

- Clone the repository
- ` cp .env.sample .env`
- Make required changes in .env file
- `docker-compose build`
- `docker-compose up`

# Directory Structure

- Backend: It has all the provisioning scripts and API/Websocket server written in Go.
  - The provisioning instance template is found at "backend/index.html". This is the HTML template file based on which provisioning instance is created.
- Frontend: It houses the main provisioning interface.

# Developing the Backend

- `docker build` after making changes
- `docker up` to test the changes

# Developing the Frontend

- `yarn install` inside frontend/src/app
- `yarn serve`
