Lazy Streams
Discover how to use lazy streams in Node.js to delay expensive stream initialization until data consumption begins. This approach helps manage resources effectively when creating multiple streams and avoids file descriptor limits, improving stream handling efficiency.
We'll cover the following...
Sometimes, we need to create a large number of streams at the same time, for example, to pass them to a function for further processing. A typical example is when using archiver, a package for creating archives such as TAR and ZIP. The archiver package allows us to create an archive from a set of streams, representing the files to add. The problem is that if we want to pass a large number of streams, such as from files on the filesystem, we would likely get an EMFILE, too many open ...
