amberrignell / sugarwizard-backend

This is the backend for the Sugarwizard app - an open source web app to help diabetics calculate their insulin dosage.

Setup to run locally:

Go to MongoDB and create a database, a user and a free Shared Tier Cluster (you can use any cloud provider or region). Make sure to set the network access so that your IP address has access - if in doubt set to anywhere (0.0.0.0/0)
Go to connect -> connect your application and set the .env DATABASE_URL to the connection string. Don't forget to replace <password>
Set the .env JWT_SECRET to a random string.
Run npm i then npm start and the server should be running on localhost:3000.

User model:

{
  email: { type: String, required: true },
  password: {type: String, required: true},
  insulinRatio: { type: Number, required: true},
  carbRatio: { type: Number, required: true},
  glucose_reading: { type: Array },
  time: { type : Array }
},
{ timestamps: true },

REST API with four routes (see postman collection here):

Post /api/login —> calls loginUser

{
  "email": "",
  "password": "",
}

• Get the email and password from the request
• Find a user with the same email
• Compare the password with the hash for that user using bcrypt.compare
• Create and return a JWT token with the user id as the payload

Post /api/signup ==> calls createUser:

{
  "email": "",
  "password": "",
  "insulinRatio": 1,
  "carbRatio": 1
}

• check if there is an existing user with that email
• hash the password with bcrypt and set the hash as the password’s value
• create a user using the user model
• Save the user
• Create a token using JWT
• Return the token

Put /api/store-data —> calls authentication middleware and updateUser

{
"glucose_reading": 1,
"time": ""
}

Get /api/profile —> calls authentication middleware and getUserById
