JavaScript, Testing, ES Modules, and other ruminations on software development

The standard way of storing package code is one Git repository per package. But when dealing with a modular codebase that has hundreds of packages, this…

The reason is that it removes the friction from the development process. And reducing…

Another interesting thing to notice was her lack of fear: she deployed code she’d never…

How does one ensure that even if the size of the codebase of a company grows and the size of the development team grows, the development velocity…
(Hey, if you want to come work with me at Roundforest, and try out ESM on Node.js, feel free to find me on LinkedIn or on Twitter (@giltayar)) This is part 3 of the guide for using ES modules in Node.js. Part 1: the basics of ESM The simplest Node.js ESM project Using the .js extension for ESM Part 2: “exports” and its uses (including dual-mode libraries) The exports field Multiple exports…

(Hey, if you want to come work with me at Roundforest, and try out ESM on Node.js, feel free to find me on LinkedIn or on Twitter (@giltayar)) ES Modules are the future of modules in JavaScript. They already are the rule in the frontend, but till now they couldn’t have been used in Node.js. Well, it seems that now they can. Moreover, the Node.js community is fast at work at adding support for…
(Hey, if you want to come work with me at Roundforest, and try out JSDoc typing, feel free to find me on LinkedIn or on Twitter (@giltayar)) TypeScript! For me, it’s a love-hate relationship. I started my developer life in statically typed languages (well, if we ignore Basic, which is dynamically typed): C, C++, and Java. Then somewhere around 2010, I had the good fortune to start working in…
Update, as of November 2021 ! I just tried out the new Macbook Pro M1s on our codebase, And they seem to work out really well. I’ve seen mixed results in regards to Docker compatibility, but it depends on what you’re running in Docker. Our stack is a Node.js stack, and things are pretty compatible these days. The new Apple Macs are a wonder. As the now famous AnandTech graph shows us, Apple’s ARM…
ES Module are a new way of using modules in JavaScript. Having ES modules (ESM) in Node.js means that you can now write: import fs from 'fs' import { doSomething } from './mylib.mjs' instead of using the classic CommonJS (CJS) modules: const fs = require ( 'fs' ) const { doSomething } = require ( './mylib.js' ) If you want to learn more about the whys and the hows (and are maybe wondering about…
Immutably setting a value in a JS array (or how an array is also an object) # Reducers in Redux are a place where functional programming, and the concept of immutability, are very noticeable. Immutability is not natural in Javascript, so some resort to libraries like Immutable . Me? I prefer native arrays, objects, and primitives, to library-defined data-structures — so I resort to various ES6…
Iterating Over Emoji Characters the ES6 Way # Let’s say we want to write a function that turns a string into an array of characters. Let’s try and write it: Simple. And what does that console.log display? [ 'R' , 'o' , 'b' , 'i' , 'n' , ' ' , 'H' , 'o' , 'o' , 'd' ] Good! But does it support Unicode? Let’s try a string with Hebrew characters: And… [ 'R' , 'o' , 'b' , 'i' , 'n' , ' ' , 'H' , 'o' ,…
