How this extension works

Use this extension to redact sensitive text from strings (based on defined rulesets) written to a Cloud Firestore collection.

This extension listens to your specified Cloud Firestore collection. If you add a string to a specified field in any document within that collection, this extension:

  • Redacts text from the string based on the rulesets configured in the Pangea Console Redact Dashboard; Redacted text is also replaced with predefined tags.
  • Adds the Redacted version(s) of the string to a separate specified field in the same document.

You specify the desired data types to redact such as names, email addresses, phone numbers, social security numbers, crypto keys, medical licenses, or customized your own types. You can find a list of predefined rulesets on the Pangea Console Redact Dashboard.

If the original non-redacted field of the document is updated, then the redactions will be automatically updated, as well.

Multiple collections for redactions

To redact multiple collections, install this extension multiple times, specifying a different
collection path each time. There is currently no limit on how many instances of an extension you
can install.

Multiple field redactions

To redact multiple fields, store a map of input strings in the input field:

  first: "My name is Bob",
  second: "My phone number is 415-555-5555"
