XLite currently displays various assets without any indication of their "health" status. We want to improve this by adding a check for each asset and displaying an indicator based on the result of this check.
Suggested solution:
Use the getBlockHash(height) method from the rpc-controller.js or modules_rpc-controller.js file to check the blockchain height for each asset periodically. This method returns the hash of a block at a given height.
Make this check every 30 seconds for each asset.
If an asset is online (a non-null hash is returned), no additional indicator is necessary.
If an asset is offline (an empty hash or null is returned), display an indicator next to the asset.
This indicator should include a message stating "This asset is currently offline!", and a warning icon (design and assets to follow)
The health check and the indicator should be added to the asset rendering section of the code (possibly in the balance.js component)
add a method to handle any errors or exceptions in the health check.
QA
[ ] A health check should be performed for each asset every 30 seconds.
[ ] If an asset is offline, an indicator with an appropriate message and icon is displayed next to the asset.
[ ] If an asset is online, no additional indicator is displayed.
[ ] The application should handle any exceptions or errors in the health check and prevent any crash or major disruption.
NB: we should ensure that the frequency of the health checks do not negatively impact the application's performance. If necessary, we will adjust the check interval or implement a method to stagger the checks for different assets (eg only checking when a user views an asset).
