A Writable stream is one that we write data to and it can pipe into a Readable, Duplex, or Transform stream. We can use these streams to write data in a chunked manner so a consuming stream can process the data in chunks instead of all at once. The API for a writable stream is quite similar to that of a Readable stream except for the methods that are available to us.
Building a Writable stream
Understanding the Writable stream interface
A writable stream gives us nearly the same options that are available to a Readable stream so we will not go into that. Instead, we will take a look at the four methods that are available to us—one that we must implement and the rest that we can implement:
- The _write method allows us...
