A React component goes through different phases as it lives in an application, though it might not be evident that anything is happening behind the scenes. Those phases are: mounting updating unmounting error handling There are methods in each of these phases that make it possible to perform...

Netlify Functions for Sending Emails

23.4.2019
Let's say you're rocking a JAMstack-style site (no server-side languages in use), but you want to do something rather dynamic like send an email. Not a problem! That's the whole point of JAMstack. It's not just static hosting. It's that plus doing anything else you wanna do through JavaScript...

12.4.2019

localStorage is... Good! It's an incredibly easy API to use. localStorage.setItem('name', 'Chris'); let name = localStorage.getItem('name'); Bad! Philip Walton explains why: localStorage is a synchronous API that blocks the main thread, and any time you access it you potentially prevent your...

CSS Houdini Could Change the Way We Write and Manage CSS

CSS Houdini may be the most exciting development in CSS. Houdini is comprised of a number of separate APIs, each shipping to browsers separately, and some that have already shipped (here's the browser support). The Paint API is one of them. I’m very excited about it and recently started to think...

The Whole Spreadsheets as Databases Thing is Pretty Cool

18.3.2019
A spreadsheet has always been a strong (if fairly literal) analogy for a database. A database has tables, which is like a single spreadsheet. Imagine a spreadsheet for tracking RSVPs for a wedding. Across the top, column titles like First Name, Last Name, Address, and Attending?. Those titles...

7 things you should know when getting started with Serverless APIs

14.3.2019
I want you to take a second and think about Twitter, and think about it in terms of scale. Twitter has 326 million users. Collectively, we create ~6,000 tweets every second. Every minute, that’s 360,000 tweets created. That sums up to nearly 200 billion tweets a year. Now, what if the creators...

Get Started with Node: An Introduction to APIs, HTTP and ES6+ JavaScript

11.3.2019
Jamie Corkhill has written this wonderful post about Node and I think it’s perhaps one of the best technical articles I’ve ever read.

1.3.2019
While it is important to have a well-tested API, solid test coverage is a must for any React application. Tests increase confidence in the code and helps prevent shipping bugs to users. That’s why we’re going to focus on testing in this post, specifically for React applications. By the end, you’ll...

JavaScript Proxy

26.2.2019
I’ve always loved the flexibility of Objects and prototypes in JavaScript, but for a long time, I felt that a level of dynamism was lacking. JavaScript eventually added get and set methods for object properties, which was an awesome step, but there was still room for improvement....

Getting to Grips with the Airtable API

14.2.2019
The Airtable web app is pretty neat. You can use it like a spreadsheet but it’s useful for all sorts of other things too. The neatest thing about it for me is that it has an API so that you can treat it like a database. I’ve been thinking about making weekly notes for the different teams I work...

​​Avoiding those dang cannot read property of undefined errors

13.2.2019
​​​​Uncaught TypeError: Cannot read property 'foo' of undefined.​ The dreaded error we all hit at some point in JavaScript development. Could be an empty state from an API that returns differently than you expected. Could be something else. We don’t know because the error itself is so general...
