Issue Number

fixes #59

Describe the changes you've made

I have added a timeout tracker which periodically checks if the session has expired or not. The session limit is set to 1 hour by default. In order to change the limit, we can add a sessionLimit field in the src/config.json, and provide the number of seconds as its value.

For example, if we want the session to be of 20 seconds, as shown in the demo below, the file should be

{
    "apiURL": "<url>",
    "APP_ENV": "dev",
    "sessionLimit": 20
}

The basic flow is -

• User logs into the application
• The expirationTime is saved into in local storage
• A timeout tracker is started to check if the session had expired periodically
• When the session expires, the user is logged out automatically
