The Many Ways of Getting Data Into Charts

Data is available everywhere nowadays, whether it’s in a plain text file, a REST API, an online Google sheet… you name it! It’s that variety of context that makes building graphs more than simply having a database in your local project — where there is data, there is a way.

That’s pretty much what we’re going to look at in this post: making JavaScript data visualizations using data from a variety of sources.… Read article

Netlify Functions for Sending Emails

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 and APIs.

The Whole Spreadsheets as Databases Thing is Pretty Cool

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.

7 things you should know when getting started with Serverless APIs

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.

Need to Test API Endpoints? Two Quick Ways to Do It.

Here's a possibility! Perhaps you are testing your JavaScript with a framework like Jasmine. That's nice because you can write lots of tests to cover your application, get a nice little UI to see the output, and even integrate it with build and deploy tools to make your ongoing development work safer.

How I Built a GPS-Powered Weather Clock With My Old iPhone 4

My first smartphone was an iPhone 4s. I remember the excitement of exploring its capabilities at a time when it was the coolest thing around. Eventually, of course, I replaced it with a newer model and the old iPhone, still in mint condition, gathered dust for two years. What a waste!

But was it? It occurred to me that I could repurpose the old iPhone to create a useful weather clock for our hallway.… Read article

Let’s make a form that puts current location to use in a map!

I love shopping online. I can find what I need and get most things for a decent price. I am Nigerian currently working and studying in India, and two things I dread when shopping online are:

  1. Filling out a credit card form
  2. Filling out shipping and billing address forms

Maybe I’m just lazy, but these things are not without challenges! For the first one, thanks to payment processing services like PayPal and e-wallets, I neither have to type in my … Read article

Using data in React with the Fetch API and axios

If you are new to React, and perhaps have only played with building to-do and counter apps, you may not yet have run across a need to pull in data for your app. There will likely come a time when you’ll need to do this, as React apps are most well suited for situations where you’re handling both data and state.

The first set of data you may need to handle might be hard-coded into your React application, like we … Read article
