GitHub Security Code Scanning section

[timlevett]

This introduces a very very basic version of the Security / Code Scanning Results page in a given github repo;

TODO

• be able to filter by state (right now it just returns all states)
• fetch more than just the first 100
• be able to add a ref filter (this is exposed to the UI)
• Filter by time range (should be off by default IMO)
• Tests

Good one Tim.

Have you considered using list-code-scanning-alerts-for-an-organization api when the repo field is empty?

Also, Let's know once your TODO items are added. We can take a closer look
