Composability
Explore how to compose Node.js streams using the pipe method to create modular and reusable processing pipelines. Understand how to add encryption by integrating Transform streams for client-side encryption and server-side decryption. Learn to enhance your data handling by combining multiple streams cleanly and efficiently, paving the way to advanced stream usage in Node.js.
We'll cover the following...
The code we’ve seen so far has already given us an overview of how streams can be composed thanks to the pipe() method, which allows us to connect the different processing units, each being responsible for one single functionality, in perfect Node.js style. This is possible because streams have a uniform interface, and they can understand each other in terms of API. The only prerequisite is that the next stream in the pipeline has to support the data type produced by the previous stream, which can be either binary, text, or even objects.
To take a look at another demonstration of the power of this property, we can try to add an encryption layer to the gzip-send/gzip-receive application that we built previously.
In order to do this, we’ll need to apply some small changes to both our client and server. ...
