Welcome to the Babytime Microservice! This microservice provides data for the "Babytime" web app, allowing you to retrieve information related to baby activities and schedules.

Getting Started

Prerequisites

Make sure you have the following installed:

• Node.js
• npm (Node Package Manager)

Communication

1. Client-side (React):

Requesting Data (Sending HTTP Reuqests):

• The frontend is responsible for sending HTTP requests to the server to perfrom various operations such as creating, reading, updating, and deleteing activities.
• It uses the Fetch API to make HTTP requests to the server's API endpoints.
• For example:

const loadActivities = async () => {
    try {
      const response = await fetch('/activities');
      const data = await response.json();
      setActivities(data);
    } catch (error) {
      console.error("Error fetching activities:", error);
    }
  };

2. Server-side (Node.js and Express):

Receiving Data (Handling HTTP Requests):

• On the server side, you use Express.js to handle incoming HTTP requests.
• Using Routes and controllers.
• For example:

app.get('/activities/:_id', (req, res) => {
    const activityId = req.params._id;
    activities.findActivityById(activityId)
        .then(activity => { 
            if (activity !== null) {
                res.status(200).json(activity);
            } else {
                res.status(404).json({ Error: 'Resource not found' });
            }         
         })
        .catch(error => {
            res.status(400).json({ Error: 'Request failed' });
        });

});

3. Database (MongoDB):

Storing and Retrieving Data:

• MongoDB is used as the database to store and retrieve data.
• In the server-side code, you'll have functions to interact with the MongoDB database using a library like mongoose.
• For example:

import mongoose from 'mongoose';
import 'dotenv/config';

mongoose.connect(
    process.env.MONGODB_CONNECT_STRING,
    { useNewUrlParser: true }
);


// Connect to to the database
const db = mongoose.connection;
// The open event is called when the database connection successfully opens
db.once("open", () => {
    console.log("Successfully connected to MongoDB using Mongoose!");
});

/**
 * Define the schema
 */

const activitySchema = mongoose.Schema({
    name: { type: String, required: true },
    start: { type: String, required: true },
    end: { type: String, required: false },
    amount: { type: Number, required: false },
    color: { type: String, required: false },
    memo: { type: String, required: false }
});
