Get diff in after hook

[ericuldall]

Is there some way to get a diff in an after hook?

Use Case

I'm building an activity hook that will run after create, patch, update, delete in order to show an audit log of activity in our admin dashboard. Right now it works pretty good I can see a list like A User was updated by John Smith on {{Date}}, however I'm not finding it obvious if there's a way to see what was changed in the after hook. My initial thought was to grab the data payload from a create, patch, update however it seems that is no longer available in the after hook.

Am I wrong or is there some way to persist the original payload for use in an after hook?

I just ended up writing a custom before hook to handle it. Using https://npmjs.com/package/deep-diff:

prepareDiff: context => {
        if (context.id) {
            return context.service.get(context.id).then(stash => {
                context.diff = diff(JSON.parse(JSON.stringify(stash)), JSON.parse(JSON.stringify(context.data)));
                return context;
            }).catch(e => {
                console.log(e);
                return context;
            });
        }
        return context;
    }
