How to do it…

The code is quite straightforward, and short, too. We just have to require the needed modules, create an input stream for the file that we'll read, an output stream for the file that we'll create, and pipe the first stream to the second one; nothing could be simpler:

// Source file: src/zip_files.jsconst zlib = require("zlib");const fs = require("fs");const inputStream = fs.createReadStream(    "/home/fkereki/Documents/CHURCHES - Digital Taxonomy.pdf");const gzipStream = zlib.createGzip();const outputStream = fs.createWriteStream(    "/home/fkereki/Documents/CHURCHES.gz");inputStream.pipe(gzipStream).pipe(outputStream);
