Setup Databases

  • OPTIONAL - Setup replica set for the new database
    • Navigate to the MongoDB installation path

    • Type rs.initiate() (Make sure other there are no other running mongoDB services)

Setup Webserver

  1. Install all packages with npm install
  2. If any changes were made to the hardware/ database setup, change the config variable in the server.js file. Point the server to database and specify the ports for the gui and hardware.
const config = {
  DB: 'mongodb://127.0.0.1:27017/', // database URL
  PORT: 9090, // GUI port see it at localhost:9090
  WS_PORT: 8011, // hardware connection port
};

Startup Procedure

  1. Start database. Application can also work without a database. However, this means collected data will not be saved.

    mongod --dbpath "path-to-database"

  2. Start node server.

    node server.js
#or nodemon server.js

  3. Go to http://localhost:90/plots?id=defaultCollection to directly view the plots page.

Once hardware is connected, then data collected from the hardware will the plotted on the plots_page.html
