What is Apache-Age Viewer

Apache-Age Viewer is a web based user interface that provides visualization of graph data stored in a postgreSQL database with AGE extension. It is graph visualisation tool, for Apache AGE.

This is a sub-project of the Apache AGE project.

Recommend Node Version & install module

• Node version - ^14.16.0

• Node Module - pm2

Install latest pm2 with : npm i pm2

pm2 is an NPM module to run the project in production mode, and hence is optional for getting started with setting up development environment for Age-Viewer

Running Age-Viewer

• Install the required node modules using :
  npm run setup
• Run Age-Viewer using : npm run start

This will start the age-viewer on http://localhost:3000 if port 3000 is free.

How to build using command

• Build the front-end : npm run build-front

• Build the back-end : npm run build-back

• Start the project in production mode :

    pm2 stop ag-viewer-develop
  
    pm2 delete ag-viewer-develop
  
    pm2 start ecosystem.config.js
  
  

  How to start using Age-Viewer

• To start using Age-Viewer we need to have a running postgreSQL database server with Apache Age Extension

  Setting up the PostgreSQL server with AGE extension

  • Easiest way for Windows, Mac-OS and Linux Environment using Docker

  Install docker in advance (https://www.docker.com/get-started), install the version compatible with your OS from the provided link.

  Run Using Docker :

  • Get the docker image - docker pull apache/age

  • Create AGE docker container

  docker run --name myPostgresDb -p 5455:5432 -e POSTGRES_USER=postgresUser \
  -e POSTGRES_PASSWORD=postgresPW -e POSTGRES_DB=postgresDB -d apache/age

  Docker variables	Description
  --name	Assign a name to the container
  -p	Publish a container’s port(s) to the host
  -e	Set environment variables
  -d	Run container in background and print container ID

• To Get the running log of the docker container created - docker logs --follow myPostgresDb

• To Get into postgreSQL Shell (There are two ways this can be done) -

  • First get into docker shell using - docker exec -it myPostgresDb bash
    Then get into postgreSQL shell using - psql -U postgresUser postgresDB

  OR

  • Alternatively postgres shell can also be assessed directly (without getting into the docker shell) - psql -U postgresUser -d postgresDB -p 5455 -h localhost and put in postgresPW when prompted for password.

• After logging into postgreSQL shell follow the Post-Installation instruction to create a graph in the database.

Connect Apache Age-Viewer to PostgreSQL Database

Initial Connection Layout To Connect to postgreSQL server running from Docker Container

• Connect URL - localhost
• Connect Port - 5455
• Database Name - postgresDB
• User Name - postgresUser
• Password - postgresPW

The following field is same as used to make the docker container specified above as flags.
