Introduction

A simple server that uses decision tree based algorithm to perform different actions based on the user selection

Getting started

To set up the server, download the latest release. Then create copy the .env.example file to .env and change the required environment variables.

Environment variables

• DATABASE_URL: The postgres database url for the server with the format postgres://user:password@server_name:port/db_name
• POSTGRES_PASSWORD: The database password (Only applies to docker compose setup)
• POSTGRES_USER: The database user (Only applies to docker compose setup)
• PORT: The port where the server should run on.
• API_MOUNT_POINT: The endpoint on which the server API will be accessible
• API_KEY_ADMIN: An API key that every request must set in the header as x-api-key

Using node

This requires at least Node version 16.x.

Run

 yarn install --prod

To get required dependencies and run the app using the command:

yarn start

Using Docker (Recommended)

This requires at least Docker Engine version 23.0.5 and Docker Compose Plugin version v2.15.1. To run the app using docker there are 2 ways:

Docker build

First, build the docker image

docker build . <image_name>:<app-version>

And then run the app container using:

docker run <image_name>:<app-version> --port 3000:<port>

Make sure the DATABASE_URL points to an existing Postgres database

Docker compose

This is recommended if you don't have an external Postgres database. To run the app use:

docker compose up -d --build

Development

You can set up the project by cloning into your local machine.

Get dependencies

Get the required dependencies by running:

yarn install

Environment

Copy .env.example to .env file and change the variables as required.

Run in development mode

To run the server in development mode use:

yarn dev

Build

To build the app run:

yarn build

This will create a zipped build in the build folder
