Musings on writing code
I’m sure it happened to you too. Just remember. That horrible moment when you time-travelled using undo - to copy and paste that line you deleted twenty minutes ago but for some reason you really, really, need it now - and then you hit a key and insert a letter. And just like that, your way back is gone.…
Sequelize is a pretty nice ORM wrapper for Node.js. It keeps focus on writing JavaScript and helps avoid the annoying mental context-switch to SQL. And even though it's a somewhat leaky abstraction it makes a programmer more productive. And in this century, who doesn't like being more productive, huh? Now, speaking about leaky abstractions, there's one syntactic issue that…
We hear a lot of praise recently about the introduction of new cool features in ES6. One of those long awaited ones is the let keyword. And rightly so - it has saner scoping rules, does not hoist (I know, I know but let's ignore TDZs here) and generally does not “pollute” your function’s namespace as much as var.…
I’m leaving you. I'm sorry. All good things must come to an end. You introduced so many great ideas to the JS world (although you borrowed from elsewhere but...psst). Arrow functions. Destructuring. Comprehensions. I dare to say you made writing JavaScript code fun again. And my Kinesis keyboard and my wrist tendons will forever be grateful. But now…
Hapi plugins are a great way to break your web server up into isolated pieces of logic. When you structure your app with plugins you'll get easier code reusability, more maintainability and you'll become a happier, prettier person with better posture and beautiful complexion. However, there's one thing you should not do. And I see it done disturbingly often (not…
Hapi is a very solid framework that makes writing maintainable and testable web servers so much easier than, say, Express, that I'm seriously considering flying to Los Gatos just to buy @eranhammer a beer. There's just this one thing bothering me. If you're using Mocha, no doubt you'll very soon come across #1299 - exceptions thrown in server.inject do…
