API

consumeUntil(stream, pattern, callback)

The module exposes a single function which takes 3 arguments:

• stream - The stream to consume
• pattern - Either a string or a buffer containing the pattern to look for in the stream
• callback - The callback will be called when the pattern is detected. The data consumed up until the pattern will be given as the second argument. An error is given as the first argument if the stream either ends before the pattern is found or emits an error
