Azure Map Leaflet plugin token expired handling

Question

Azure Map Leaflet plugin token expired handling

Janrey Ocfemia 35

I'm using the Azure Maps Leaflet plugin https://github.com/Azure-Samples/azure-maps-leaflet.

I've run into an issue when using "anonymous" authentication type eg. (https://learn.microsoft.com/en-us/azure/azure-maps/how-to-secure-spa-app). The issue occurs when the map token has expired and the user closes the tab then re-opens, they'll get an exception/error "Token Expired, Try again". It doesn't appear that azure-maps-leaftlet handles expired tokens. It seems to store the token in local storage but doesn't handle the expiry.

Does anyone know if azure-maps-leaflet will be able to support expired token handling in future?

Checking the source code of the Azure Maps leaflet control there does appear to be code to handle token expiry when the map is reloaded and the token is retrieved from cache: https://github.com/Azure-Samples/azure-maps-leaflet/blob/7d9786a050549e440ddb78252949689f03215574/src/internal/AuthenticationManager.ts#L259

That said, I think there may be some room for improvement. It looks like it doesn't monitor the expiry time of a token retrieved from cache. I've just pushed an update to that project that should handle this better. Grab the latest code from the dist folder of that project.

Hi @rbrundritt , that's looking better.

However, I think the issue we've faced is that if the user has closed the tab/window, timers will not run and will not attempt to renew the token. When the user reopens the page, the old token will be retrieved from local storage, at this point AuthenticationManager finds that the token has expired and throws an exception.

We've just worked around it for now by forcing a renew token instead of throwing an exception around this line https://github.com/Azure-Samples/azure-maps-leaflet/blob/ed7cd892725d69816a927ae64ebfff1d7473ada5/src/internal/AuthenticationManager.ts#L267

The update I made yesterday's hold have made it better. I just checked in another update that should absolutely address this issue, but may open up other potential issues if invalid auth info is provided (recursive retries).

Awesome! That would definitely fix the issue we're facing. We did think about the potential for retry loops, hopefully there'll be something for handling that in future. For now, this will do us! Thanks :)

Handling token expiration in Azure Maps Leaflet plugin typically involves refreshing the token before it expires to ensure uninterrupted service. If the current version doesn't handle this automatically, developers may need to implement custom logic to refresh tokens, considering security best practices. Always refer to the latest documentation or community discussions for the most up-to-date information on features and improvements.
