setToServerValue number

Sets the field to the given server value.

The number should be among the values of ServerValue
increment Object

Adds the given value to the field's current value.

This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If either of the given value or the current field value are doubles, both values will be interpreted as doubles. Double arithmetic and representation of double values follow IEEE 754 semantics. If there is positive/negative integer overflow, the field is resolved to the largest magnitude positive/negative integer.

This object should have the same structure as Value
maximum Object

Sets the field to the maximum of its current value and the given value.

This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If a maximum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the larger operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The maximum of a zero stored value and zero input value is always the stored value. The maximum of any numeric value x and NaN is NaN.

This object should have the same structure as Value
minimum Object

Sets the field to the minimum of its current value and the given value.

This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the input value. If a minimum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the smaller operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The minimum of a zero stored value and zero input value is always the stored value. The minimum of any numeric value x and NaN is NaN.

This object should have the same structure as Value
appendMissingElements Object

Append the given elements in order if they are not already present in the current field value. If the field is not an array, or if the field does not yet exist, it is first set to the empty array.

Equivalent numbers of different types (e.g. 3L and 3.0) are considered equal when checking if a value is missing. NaN is equal to NaN, and Null is equal to Null. If the input contains multiple equivalent values, only the first will be considered.

The corresponding transform_result will be the null value.

This object should have the same structure as ArrayValue
removeAllFromArray Object

Remove all of the given elements from the array in the field. If the field is not an array, or if the field does not yet exist, it is set to the empty array.

Equivalent numbers of the different types (e.g. 3L and 3.0) are considered equal when deciding whether an element should be removed. NaN is equal to NaN, and Null is equal to Null. This will remove all equivalent values if there are duplicates.

The corresponding transform_result will be the null value.

WriteRequest

The request for Firestore.Write.

The first request creates a stream, or resumes an existing one from a token.

When creating a new stream, the server replies with a response containing only an ID and a token, to use in the next request.

When resuming a stream, the server first streams any responses later than the given token, then a response containing only an up-to-date token, to use in the next request.

Properties:
Name Type Description
database string

The database name. In the format: projects/{project_id}/databases/{database_id}. This is only required in the first message.
streamId string

The ID of the write stream to resume. This may only be set in the first message. When left empty, a new write stream will be created.
writes Array.<Object>

The writes to apply.

Always executed atomically and in order. This must be empty on the first request. This may be empty on the last request. This must not be empty on all other requests.

This object should have the same structure as Write
streamToken Buffer

A stream token that was previously sent by the server.

The client should set this field to the token from the most recent WriteResponse it has received. This acknowledges that the client has received responses up to this token. After sending this token, earlier tokens may not be used anymore.

The server may close the stream if there are too many unacknowledged responses.

Leave this field unset when creating a new stream. To resume a stream at a specific point, set this field and the stream_id field.

Leave this field unset when creating a new stream.
