A very simple script to check real time availability of COVID vaccine by querying the offical COWIN server.

It helped me book vaccination appointment.

It queries the COWIN servers every 5 seconds and displays on screen the centers at which vaccination slots are available.

Simply change the variable values as per your need

• District in which you are looking for vaccine.
• District ID can be easily obtained from COWIN website
• Example: 363 is code for Pune(Maharashtra).
• const DISTRICT_ID = 363;

• Date for which the system will check vaccine availability
• Format = DD-MM-YYYY
• const DATE = '01-06-2021';

• Vaccine type to look for
• Valid values (any one): COVISHIELD or COVAXIN
• const VACCINE = 'COVISHIELD';

• Age group for which to look for vaccines
• Valid values (any one): 18 or 45
• const AGE = 18;

• For first dose value should be 1, for second dose value should be 2
• const DOSE = 1;

1. Clone this repo
2. Run npm install to install required npm modules
3. node launch.js to run the script
4. Enjoy!

You might get "Authentication Error" message some times. Just restart the script. It works!
