Live Example

  import FireStoreParser from 'firestore-parser'
  const projectID = 'PROJECT_ID'
  const key = 'API_KEY'
  const doc = 'DOCUMENT'
  const url = `https://firestore.googleapis.com/v1beta1/projects/${projectID}/databases/(default)/documents/${doc}?key=${key}`

Data Structure

The Firestore JSON returned in the REST API, uses value type as keys. This can be difficult to work with since you have to know the data type prior getting the value. The firestore-parser removes this barrier for you.

JSON response from Firestore

{
	"player": {
		"mapValue": {
			"fields": {
				"name": {
					"stringValue": "steve"
				},
				"health": {
					"integerValue": "100"
				},
				"alive": {
					"booleanValue": true
				}
			}
		}
	},
	"level": {
		"integerValue": "7"
	}
}
