The error() method of the ReadableStreamDefaultController interface causes any future interactions with the associated stream to error.
Syntax
readableStreamDefaultControllerInstance.error(e);
Parameters
- e
- The error you want future interactions to fail with.
Return value
Void.
Exceptions
- TypeError
- The source object is not a
ReadableStreamDefaultController, or the stream is not readable for some other reason.
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.
