A new (and easy) way to hide content accessibly

When I want to hide content accessibly, I always turn to Jonathan Snook’s snippet.

.element-invisible {
position: absolute !important;
height: 1px; width: 1px;
overflow: hidden;
clip: rect(1px 1px 1px 1px); /* IE6, IE7 */
clip: rect(1px, 1px, 1px, 1px);

But yesterday, I happened to chance upon Scott O’Hara’s article on hiding content. Scott says we only want to hide content in three different contexts:

  1. Hide it completely
  2. Hide it visually
  3. Hide it from screen readers

JavaScript async and await

Asynchronous JavaScript has never been easy. For a while, we used callbacks. Then, we used promises. And now, we have asynchronous functions.

Asynchronous functions make it easier to write asynchronous JavaScript, but it comes with its own set of gotchas that makes life hard for beginners.

In this 2-part series, I want to share everything you need to know about asynchronous functions.

Publishing packages that can be used in browsers and Node

When you create a package for others to use, you have to consider where your user will use your package. Will they use it in a browser-based environment (or frontend JavaScript)? Will they use it in Node (or backend JavaScript)? Or both?

If you want to create a package that’s usable in both browsers and Node, this article is here to help.

You’ll learn:

  1. How to write packages for use in browsers
  2. How to write packages for use in Node
  3. How to publish your packages for use in both browsers and Node

How to ignore files from your npm package

You can decide what files people get when they download your package in three ways:

  1. With the .gitignore file
  2. With the .npmignore file
  3. With the files property

We’ll look at each method and discuss which methods you should (or shouldn’t) be using.

Excluding files with gitignore

First, npm will check your repository for a .gitignore file. If there is a .gitignore file, npm will ignore files according to what’s listed in the .gitignore file.

This is the most common way package authors prevent people from downloading extra files.

Let’s go through a simple example. Say you have the following directory structure.

- project-name/
|- index.js
|- package.json
|- node_modules/

Let’s say you don’t want people to download the node_modules folder. You also don’t want to save the node_modules in the Git repository.

What you’ll do is create a .gitignore file.

# .gitignore

In this case, both Git and npm ignore the node_modules folder.

Blacklisting files with npmignore

A second way is to blacklist files with a .npmignore file. The .npmignore file works the same way as a .gitignore file. If a file is listed in the .npmignore file, the file will be excluded from the package.

Important note: If you have a .npmignore file, npm will use the .npmignore file. npm will ignore the .gitignore file altogether. (Many developers mistakenly believe npm will use both .npmignore and .gitignore files. Don’t make the same mistake!).

You can use this method if you want to exclude files from the package, but keep them in the Git repository.

Let’s walk through another example. Let’s say you’ve written tests for your package and you put them all in a tests folder. This is your directory structure:

- project-name/
|- index.js
|- package.json
|- node_modules/
|- tests/

You want to exclude node_modules from both your Git repository and your package.

You want to include tests in your Git repository, but exclude it from the package.

If you opt for the npmignore file method, you can write these in your .gitignore and .npmignore files:

# .gitignore
# .npmignore

Whitelisting files with the files property

A third method is to whitelist files you want to be included in the package.json file, under the files property.

Note: npm will prioritize this method over other methods mentioned above. This is the easiest method to limit what files others download.

This approach is pretty simple. What you need is to create a files property in the package.json file. Then, provide a list of files you’d like to include.

Here’s an example:

"files": [

Note: Some files, like package.json, is always included in a package. You don’t have to write these files in the files property.

Which method to use?

All three methods work. Pick the one you’re most comfortable with. For simple projects, the .gitignore file method should suffice.

If your project is more advanced, you might want to blacklist files with .npmignore or whitelist files with the files property. Pick one. There’s no need for both.

A quick tip

You can use npm pack to generate a package. This package includes files other people will get.

npm pack

Try it!

The best time to npm init

When should you npm init?

Most developers run npm init right after creating and navigating into a new project.

It makes sense to npm init at the start of the project because we use npm to download dependencies. Once we npm init, we can begin downloading (and saving) our dependencies.

For most projects, this workflow works.

But if you’re creating an open source project, the best time to npm init is slightly later. If you npm init right after creating and navigating into the project, you’ll miss out a few things.

How to publish packages to npm (the way the industry does things)

It’s simple to publish a package onto npm. There are two steps:

  1. Create your package.
  2. Publish the package.

But publishing packages the way the industry does it? Not so simple. There are more steps. We’ll go through what steps are required, and I’ll show you an easy way to publish and update your package.

How to use JSDelivr

The most newbie-friendly way to add a library to a project is to:

  1. Search for the library
  2. Look for the source file
  3. Copy the source file
  4. Paste what you copied into the project.

This works, but it’s a painful process. It easier if you use CDNs like JSDelivr.

My CSS reset

Many frontend developers begin styling their websites with Normalize. Some developers have personal preferences they add on to Normalize.css. I have my preferences too.

In this article, I want to share these preferences with you. personal CSS reset (that I use in addition to Normalize.css) with you.

Setting up my new Mac (Part 2—the migration process)

Setting up a new Mac is painful. Here are some of the things I have to do:

  1. Install all 47 applications I use every day.
  2. Provide the right credentials for each application.
  3. Change macOS default settings to the ones I like.
  4. Set up coding configurations.
  5. Move files from the old Mac to the new one.

I estimate at least a three day’s worth of work (downloading things and waiting for them to download 😴) if I have to install everything manually.

But I was able to set my computer up in hours (automatically) thanks to dotfiles.

Setting up my new Mac (Part 1—the apps I use)

My first task in 2019 is to get a new computer. I didn’t want to change computers, but my old one gave way and I had no choice 😭.

Since I’m already switching computers, I thought it’ll be interesting to share the apps I use on a daily basis.

I hope you find some of them interesting!
