toFirestoreValue()function

toFirestoreValue(value: unknown, caller: AnyCaller = toFirestoreValue): FirestoreValue

Param	Type
`value`	`unknown`	The value to convert (null, boolean, string, finite number, array, or plain object). required
`caller`	`AnyCaller`	Caller function used to attribute thrown errors. Defaults to `toFirestoreValue`

Return
`FirestoreValue`	The Firestore JSON value.

Throws
`unknown`	`ValueError` if the value cannot be represented (e.g. `undefined`, functions, non-finite numbers, class instances).

Convert a data value to its Firestore REST API JSON representation.

Safe integers become integerValue (which the REST API encodes as a string), other finite numbers become doubleValue.
Arrays and plain objects convert recursively.

Examples

toFirestoreValue(123) // { integerValue: "123" }
