How to set up an M1 MacBook for web development

Editor’s note: This article was last updated on 29 March 2022 to reflect updates to Homebrew, Docker Desktop, and VS Code. 

Since I first got my M1 MacBook Air a few days ago, I’ve been pushing its limits. Not only is this machine fast, I have multiple installations running in parallel, and the temperature barely peaked at 104 degrees Fahrenheit. Overall, this machine is on a whole new level compared to the Intel chip models.

Unfortunately, it took a long time to set up my MacBook for the ideal web development environment because I had a hard time finding resources that outlined all the information I was looking for.

I’ve put together a tutorial that will help you get your web development tools up and running in just 20 minutes. This web development environment includes the following:

• Rosetta 2
• Homebrew
• Git
• Node.js
• MongoDB
• Google Chrome
• Firefox
• VS Code
• npm
• nvm
• Zsh
• Oh My Zsh
• Powerline Fonts

Let’s get started!

Why I upgraded my MacBook Pro

With over 1,200 charge cycles, my six-year-old, 13-inch MacBook Pro grew more unreliable by the day. I was faced with the tough choice of buying a new computer just around the time Apple released the M1 line.

Every review of the new chip painted an incredible picture, and they all shared a common denominator; the chip is crazy fast. Still, the decision was not so straightforward considering the M1 is based on ARM architecture.

It has been a couple of years since Apple transitioned to its own silicon. Apple once claimed that it would replace the Intel-based chips in the coming years. But, at the time of writing, the only Mac product yet to transition to Apple Silicon is Mac Pro, the desktop Mac, which may be introduced with Apple Silicon in late 2022.

Most of the apps in the app store have transitioned to Apple Silicon, even developer tools. In this article, I’ll show you how to set up these developer tools on your M1 Mac. Everything you need to follow the tutorial is pre-installed on your Mac, so we’ll spend most of our time in the terminal installing the tools on the list. Let’s get started!

Rosetta 2

First off, we need the software designed to run on Intel to speak the same language as our newly minted processor. Apple has rolled out a solution that makes the transition seamless , an emulator called Rosetta 2 that allows us to run apps that use x86 instructions, the instruction set used by Intel chips, on ARM.

Apple is planning to remove Rosetta 2 when the transition to Apple Silicon is completed. But until then, most of the tools should be transitioned to Apple Silicon as well.

Keep in mind that Rosetta is not installed by default. To use it, we have to go into the pre-installed terminal in the Utilities folder and run the following command:

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

The --agree-to-license flag will skip the interactive install and agree to Apple’s license. But, if you want to investigate what you’re signing up for, feel free to delete the flag and give the license a read.

Another way to install Rosetta 2 is by simply opening an Intel based application, then you should be prompted to install Rosetta 2:

Homebrew

We’ll use Homebrew to install most of our apps and utilities. Homebrew didn’t have proper support for M1 Macs when they were first introduced in November 2020. At the time of updating this article, Homebrew is fully supported by M1 Macs with no issues.

Open your terminal, run the command below, and input your computer’s password when prompted:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Tools

After Homebrew finishes installing, we can use it to install a majority of our tools. I have a script that does the heavy lifting for me that was derived from zellwk’s GitHub repo and tweaked to fit my environment. You can find my version of the script in the following GitHub repo.

Go ahead to the latter repo and download it. After you unzip it, cd into the setup folder. The repo includes some of my config files, but we’ll only use the brew-installs.sh script for this tutorial.

Before going any further, I recommend you open brew-installs.sh in your text editor and see everything it does and installs. You can tweak it to fit your environment because I don’t expect you to use the same tools as I do.

Once you are satisfied with it, check if the brew-installs.sh file is executable by running ls -al. If the file isn’t executable, the output will look something like this -rw-r-xr-x ... brew-installs.sh. The three dots represent some information that doesn’t concern our purposes.

To make it executable, just run chmod +x brew-installs.sh. This command should now output -rwxr-xr-x ... brew-installs.sh.

Now, assuming that your current working directory is set up, run the brew-installs.sh script by inputting ./brew-installs.sh into your terminal. Here, you can let the script do the magic for you. Depending on your internet speed, it should take roughly five minutes to download and install everything.

iTerm

iTerm, which was included in the previous setup script, should be installed by now, and therefore, we can finish the tutorial with it. It will be important to add the Rosetta layer like we first did on the terminal. One option is to duplicate the app and create a Rosetta iTerm and a regular iTerm. We can do this by following the GIF below:

Zsh

If you didn’t exclude Zsh from the brew-installs.sh script, it should be your default shell by now. If you did exclude it, run brew install zsh. Before we move on, let’s make sure Zsh is the default shell by running echo $SHELL, which should output /bin/zsh. If not, change to Zsh by running chsh -s $(which zsh).

Oh My Zsh

Let’s give Zsh some extra pizazz with Oh My Zsh. Install it by running the following command:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

There are many plugins and themes available with Oh My Zsh. You can check the full list in the GitHub repo. Syntax highlighting is one of the plugins I can’t live without.

Oh My Zsh makes it much easier to identify if you are typing the right command or if it is in your path. If the command is recognized, the text will be green. If not, it will be red:

To reduce clutter, it’s best to first cd into the cd $HOME/.oh-my-zsh/plugins path to install the plugin, then run the following command, which will automatically append the source to the folder to your .zshrc file:

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc

nvm

I tried to install nvm through Homebrew, but that failed miserably because the older versions of Node.js are not supported by the M1 architecture. So, you need to install nvm using Rosetta 2, which we installed earlier. The best alternative is to install nvm via cURL by running the following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

After the installation is done, append the following lines to your .zshrc file. If you’re using Bash, you’ll have to add it to .bash-profile or .bashrc in your home directory:

export NVM_DIR="$HOME/.nvm"
#This loads nvm
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
#This loads nvm bash_completion
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

Reset your console session and check if nvm installed properly by running nvm --version, which should output your current version 0.37.2.

Git and GitHub

Git is one of the installations included in the brew-installs, so it should be installed by now. To configure Git, let’s first set our username and email.

If you use XCode, or you installed XCode command line tools, Git should already be installed already in your machine. Apple installs all the necessary software for XCode to run.

Substitute < USERNAME > and < EMAIL > with your own and run the following command sequence:

git config --global user.name < USERNAME > &&
git config --global user.email < EMAIL > &&
git config --global --list

The recommended method to authenticate GitHub is through personal access tokens. However, this is beyond the scope of this tutorial, so please visit the official GitHub tutorial.

VS Code

To make the transition from one computer to another seamless, VS Code includes an extension called Settings Sync, which lets you upload your configurations to a GitHub Gist. Once they are up on GitHub, the extension takes care of keeping the following files in sync: settings, keybindings, snippets, workspace folders, and extensions and their corresponding configurations.

The extensions page has a thorough explanation of how to set up VS Code. Setting up VS Code with your preferred settings should only take a couple of minutes.

At the time of writing, Visual Studio Code has already transitioned to Apple Silicon. So, if you’re still using the Intel-based version of VS Code, the Apple Silicon version should give you a huge performance boost.

Powerline Fonts

Most themes in Oh My Zsh require Powerline Fonts. I pulled the following info from the official Powerline repo and converted the commands into a sequence for convenience purposes. Copy and paste the code block below into the terminal, and it will download and install Powerline Fonts for you:

git clone https://github.com/powerline/fonts.git --depth=1 &&
cd fonts &&
./install.sh &&
cd ..

You can now delete the fonts folder that was created by running rm -rf fonts. I left this command out of the sequence for security purposes.

If you’re using the Agnoster or any other theme that uses Powerline, and for some reason, you see question marks instead of the icons, you must change the Non-ASCII font in the iTerm settings. You can find this in the Text tab in Profiles. I personally use Space Mono for Powerline, but there are many other options available that you can check out.

Conclusion

Now, your M1 MacBook is set up for web development! While this article may have been dense, the good news is that your projects should compile once you install the required node_modules with npm.

If you have any questions or concerns, please leave a comment, and I’ll be glad to help you out. I hope you enjoyed this article. Happy coding!

LogRocket: Full visibility into your web and mobile apps

LogRocket is a frontend application monitoring solution that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. It works perfectly with any app, regardless of framework, and has plugins to log additional context from Redux, Vuex, and @ngrx/store.

In addition to logging Redux actions and state, LogRocket records console logs, JavaScript errors, stacktraces, network requests/responses with headers + bodies, browser metadata, and custom logs. It also instruments the DOM to record the HTML and CSS on the page, recreating pixel-perfect videos of even the most complex single-page and mobile apps.
