Global hook to edit or reject events

[pauldambra]

We're adding increasing functionality to for example mask URLs or ignore autocapture on certain elements / urls

Each time we add new collection we need to add new config. e.g. masking urls in heatmaps

We should have beforeCapture that accepts what we're about to send to any posthog endpoint and lets you edit or set to null. Set to null and we send nothing

e.g. you could have

beforeCapture: (x) => {
 if (x.properties.$current_url.indexOf(blah) > -1) {
    return null
 }
 return x
}

to not send events on particular URLs

---

things to consider?

if folk use this to not send $snapshot data they could create unplayable recordings while trying to save money / add provacy

• but we could log in cases that are dangerous like that
• or not allow you to drop things only mask them
