About

• This app shows the free slots of an executive as per their google calendar so that clients can book meetings, and it has a dashboard for the admin to see all the meetings for an executive.
• On running the app in browser (/ route), users will get an option to sign in with Google and to give app permission to read/write to their google calender.
• On signin, each user will get their custom calendar link /calendar/:<user-id> which can be shared with their clients
• The client can select any date from the dropdown and see all the available meeting slots between 9 A.M. and 5 P.M. for that date.
• On selecting a slot, the client will be redirected to /meeting/<user-id>?selectedDate=<date-string>, where we show the success page and meeting details
• Admins can go to /admin/meetings and select employee names from the dropdown to see all the scheduled meeting for that employee

Prerequisites

Setting up MongoDB Project

• Create a new cluster in MongoDB to store user and meeting data. Copy the connection string and add the MONGO_URI to the .env file

Setting up project in Google Cloud

• Go to Google Cloud Console and create a new project
• Enabling Google API
  • In sidemenu options, select APIs and Services -> Library -> Search for Google Calendar API and enable it
• Setting up the OAuth Screen
  • Inside APIs and Services -> OAuth Consent Screen -> Select User Type (Select External for testing) and click on Create
  • Now enter all the application details and click Save and Continue
  • Inside Scopes section -> Add Scopes -> Seach for Google Calendar API and select the /auth/calendar scope. This gives our app access to read and write to user's calendar -> Save and Continue
  • If your application is still in Testing phase and you selected External user type in Step 1, you'll have to provide email ids of all the users who can access your app -> Save and Continue
  • Check the app summary and click Save
• Generating Credentials
  • Again in APIs and Services, select Credentials -> Create Credentials -> oAuth Client ID
  • Select Application Type (Web Application), add authorized origin (Use http://localhost:5000 if you don't have a Domain) and a callback URL where Google will send the response after OAuth (http://localhost:5000/auth/google/callback in our case). Also add this as CALLBACK_URL in the .env file
  • Save you client id and secret as GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET in the .env file
