ES Modules & Import Maps: Back to the Future

#javascript, #webdev, #beginners, #esm

There was a time when creating a web page meant creating an html file, yet nowadays it seems impossible to build any frontend without the bottomless pit of node_modules, yielding a finely chewed yet hefty bundle.xyz.js.

Crc 32 Checksum in Wasm and Raw Js Tutorial and Benchmark

#webassembly, #webdev, #performance, #tutorial

In this tutorial we'll build a cyclic redundancy check (CRC) hashing function. More specifically, its 32 bit variant called "CRC-32". I bumped into it in the PNG specification, but it's also used in Gzip and bunch of other formats and protocols.

#redis, #node, #database

If the best code is no code at all, then the next best thing is code, that you can explain in one simple sentence. For example, like this: Redis holds a variety of structures in memory and lets you manage them through a text based command protocol. Despite, or maybe, because of its simplicity, Redis has plenty of utility in modern web architecture.
