                Designing an Undo system
              
          
    Designing an Undo system on the backend (v2)

Updates to implementation details based on today's call –


On an update call, make the client send a "snapshot" of the current record, along with the incoming UPDATE payload and save these to cache. Let's call this v1.


Generate the UPDATE query, execute it, and return the updated payload as usual, along with a unique undo_id. Additionally, save these to cache as well. Let's call this v2.


Now if the API consumer needs an undo, they need to send the undo_id, with which we should be able to look up both the v1 record, the v2 record, do a diff and execute a new UPDATE query that rolls back v2 to v1.

                Generate yarn resolutions for audit-ci fixes 
              
          
    How to use this

node auditResolutions.js

This will print some output that looks like this –
{"css-select@npm:2.1.0/nth-check":"&gt;=2.0.1"}
