Using TypeScript Node.js with native ESM

This reference guide shows how to configure a TypeScript Node.js project to work and compile to to native ESM.

Rationale

CommonJS module system was introduced by the Node.js developers due to the lack of the notion of "modules" in the original JavaScript (ECMAScript) language specification at that time. However, nowadays, ECMAScript has a standard module system called ESM — ECMAScript Modules, which is a part of the accepted standard. This way CommonJS could be considered vendor-specific and obsolete/legacy. Hopefully, TypeScript ecosystem now supports the "new" standard.

So the key benefits are:

The cbor-x's packed implementation only packs whole strings that occur multiple times, it does not search for repeated prefixes or postfixes, as they would almost certainly be vastly more expensive. Strings are packed if they occur multiples in a data structures. When using packed + record tags, strings as keys are not searched for string repetition (since it assumed repetition will mostly be eliminated by the structure reuse).

The table shows encoded size for each technique, and the encoding and decoding performance. The last column also includes the gzipped size for comparison sake (no gzip performance, but generally is about 2-4x slower with gzipping in my tests). The table compares plain CBOR encoding, packed, record structures with a 1+1 definition tag and 1+2 tag, and the combination of packed and record structures.

The first comparison test uses an 8KB JSON data structure from our database of medical studies, that has a fairly complicated and dynamic structure: https://github.com/kriszyp/cbor-x/blob/

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.
