You've found <a href="//npmjs.com/package/fflate">fflate</a>, the fastest pure JavaScript compression library in existence.
<br /><br />
You can both pack and expand Zlib, GZIP, DEFLATE, or ZIP files very quickly with just a few lines of code.
<br /><br />
Weighing in at a measly 8kB for basic compression and decompression, you don't need to worry about your bundle size ballooning.
<br /><br />
Despite utilizing multiple cores, supporting data streams, and being very memory efficient, fflate is compatible with both Node.js and browsers as old as IE11.
<br /><br />
You can read more about fflate on <a href="//github.com/101arrowz/fflate">GitHub</a>. Try the demo below to see its performance for yourself. The code boxes are editable; try changing parameters or using a different compression format.
<br /><br />
<span style={{ fontSize: '0.75em' }}>Disclaimer: I added a <span style={{ fontStyle: 'italic' }}>lot</span> of sugar (around 4 hundred lines) to the UZIP and Pako APIs to make the demo clean and asynchronous, but the fflate API is unmodified.</span>
