ReadableStreamDefaultController: error() method

The error() method of the ReadableStreamDefaultController interface causes any future interactions with the associated stream to error.

Note: The error() method can be called more than once, and can be called when the stream is not readable.

Syntax

js

error(e)

Parameters

e

The error you want future interactions to fail with.

Return value

None (undefined).

Exceptions

TypeError

Thrown if the source object is not a ReadableStreamDefaultController.

Examples

The A readable stream with an underlying push source and backpressure support example in the spec provides a good example of using ReadablestreamDefaultController.desiredSize to manually detect when the stream is full and apply backpressure, and also of using error() to manually trigger a stream error if another part of the system it relies on fails.
