Booking pal service is a REST web service that allows booking pal IoT clients to connect and manage their room calendars.

This service is using service account key to connect to Google Calendar API. Each calendar should have its own service account key. The service account key should be placed in calendarCredentials database table. The service account key should be in JSON format and stored in the serviceAccountKey column. Calendar Details table should have correct mapping to the valid calendar credentials.

To configure the service account for google calendar API, follow the steps below:

1. Go to Google Cloud Console
2. Create a new project
3. Go to Google Calendar API
4. Enable the API
5. Go to Google Cloud Console Credentials
6. Create a new service account
7. Download the service account key in JSON format
8. Store the service account key in calendarCredentials database table

You may need to share your calendar with the service account email address.

Also, get the calendar ID from your calendar settings and store it in the calendarDetails database table.

Please refer to this documentation on how to configure the service account key: https://developers.google.com/identity/protocols/oauth2/service-account

Database has two configuration tables:

1. calendarCredentials - This table stores the service account key for each calendar or set of calendars. The service account key should be in JSON format and stored in the serviceAccountKey column.
2. calendarDetails - This table stores the calendar details. The calendar ID should be stored in the calendarId column. The calendarCredentialsId column should be mapped to the correct calendarCredentials table row. The calendarName column should be the name of the calendar. apiKey column should be the API key for the calendar. API key is used to authenticate the IoT client to the valid calendar.

This is created using Bun and Elysia. To get started, install bun globally:

curl -fsSL https://bun.sh/install | bash

Then install the dependencies:

 bun install

Then run the server:

bun run start

To start the development server run:

bun run dev

Open http://localhost:3000/ with your browser to see the result.

Elysia is a hot-reloading server, so any changes you make to the code will be reflected in the browser immediately.

Also service is configured with swagger, so you can access the swagger UI at http://localhost:3000/swagger to see the API documentation.
