Interface Service

CircleCI insights

The Mentoring building block enables effective mentoring interactions between mentors and mentees. The capability aims to create a transparent eco-system to learn, connect, solve, and share within communities. MentorED is an open source mentoring application that facilitates peer learning and professional development by creating a community of mentors and mentees.

System Requirements

• Operating System: Ubuntu 22
• Node.js: v20
• PostgreSQL: 16
• Citus: 12.1

Setup Options

Elevate interface-service services can be setup in local using two methods:

Dockerized service with local dependencies(Intermediate)

A. Dockerized Service With Local Dependencies

Expectation: Run single docker containerized service with existing local (in host) or remote dependencies.

Coming soon...

Local Service with local dependencies(Hardest)

B. Local Service With Local Dependencies

Expectation: Run single service with existing local dependencies in host (Non-Docker Implementation).

Installations

Install Node.js LTS

Refer to the NodeSource distributions installation scripts for Node.js installation.

$ curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash - &&\
sudo apt-get install -y nodejs

Install Build Essential

$ sudo apt-get install build-essential

Install PM2

Refer to How To Set Up a Node.js Application for Production on Ubuntu 22.04.

Run the following command

$ sudo npm install pm2@latest -g

Setting up Repository

Clone the mentoring repository to /opt/backend directory

opt/backend$ git clone -b develop-2.5 --single-branch "https://github.com/ELEVATE-Project/interface-service.git"

Install Npm packages from src directory

backend/interface-service/src$ sudo npm i

Create .env file in src directory

interface-service/src$ sudo nano .env

Copy-paste the following env variables to the .env file:

APPLICATION_PORT=3569
API_DOC_URL= /interface/api-doc
APPLICATION_ENV= development
MENTORING_SERVICE_BASE_URL= http://localhost:3000
NOTIFICATION_SERVICE_BASE_URL= http://localhost:7201
REQUIRED_PACKAGES= "elevate-user@1.1.38 elevate-mentoring@1.1.47 elevate-scheduler@1.0.4"
SCHEDULER_SERVICE_BASE_URL= http://localhost:7401
SUPPORTED_HTTP_TYPES= "GET POST PUT PATCH DELETE"
USER_SERVICE_BASE_URL= http://localhost:3001
created_time= "2024-02-07T04:51:22.789813746Z"
custom_metadata= null
destroyed= false
version= 21

Start the Service

Navigate to the src folder of interface service and run pm2 start command:

interface-service/src$ pm2 start app.js -i 2 --name elevate-interface

Run pm2 ls command

$ pm2 ls

Output should look like this (Sample output, might slightly differ in your installation):

┌────┬─────────────────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐

This concludes the interface service and dependency setup.
