Web development on Chrome OS (Chrome Dev Summit 2019)

Today, I’m going to talk about web development on Chromebooks. Here is a quote from you. A skilled web developer. Chromebooks are awesome and, if you don’t remember saying this recently, I hope that after reading this article, it will become a daily thing. Chromebooks are known for being lightweight fast, secure web browsing machines.

They are so much more. The device portfolio has grown to include tablets, detachable z’, all-in-one, mini desktops and, of course, laptops and convertibles. Many of these are capable development devices. So what can you run on them? Well, ideas like visual studio code, Atom, webstorm tools like node, react, docker and get, and you can test your web apps with multiple browsers, including real mobile browsers as well.

You can check how your mobile app interacts with your web server all right on the same device. Okay, let’s get started and get your Chrome OS device ready for development. We are going to set up a Linux environment and then install the tools you need to start open, Chrome settings and search or scroll down to Linux. Click turn on this will download and setup a Linux environment when it’s complete, you’ll see a terminal prompt pro tip.

If you will be doing a lot of development, pin the terminal by right-clicking and choosing pin now we have a Linux environment. Let’s install some tools head over to the visual studio code website and download the Linux dot de Bie package, double click and choose install once it’s installed. You can find vs code in your app launcher. If you’re going to be using this IDE a lot, you can pin it like, we did with the terminal.

Any application with a dot de Bie package can be installed in a similar way. Let’s install atom, the process is exactly the same: download install and launch not every app has a dot de Bie package, but you can install any of your favorite tools that support Debian Linux, for example, to install sublime text, follow the Linux instructions on the website to Setup, the apt, repo and install the editor using the command-line when we install node in a few seconds, we’ll take a closer look at command-line installation and the same thing goes for apps like webstorm.

Just go to the website, follow the Linux download and install instructions. I won’t do a web storm right now. Let’s get right on to the server side of things, oh and by the way, at the end of this article, I will direct you to a page by the Chrome, OS Deverell team, with installation instructions for all the apps and more discussed in this article. Now, beyond what I mentioned today in this article, if your favorite tool is supported in Linux, it should run on Chromebooks.

For example, I, like G edit for text, editing FileZilla as an FTP, client and Inkscape for vector, graphics, editing. Today, web development usually takes more than a text editor an IDE or an FTP client. Let’s get to some other tools, so we can make some really nice web apps nodejs requires GnuPG to open up your terminal and install it with apt that command is sudo apt, install GnuPG 2. If you’re new to apt, you can probably guess that by replacing GnuPG 2 with whatever package name you want, it will install that package now.

Finding the right package name can sometimes be the tricky part note, as we continue with this article and other terminal commands. I won’t read every line out loud, but, as mentioned, I will provide a link at the end that has them all now that the dependency is installed. Let’s get nodejs run this curl command, followed by another apt, install command for node. That’s it. No js’ is ready to go, don’t believe me! Well, let’s try it out with procs use git to clone the procs repo an NPM to install, build and serve the proxy web app navigate to localhost 8080 in your web browser and check it out pretty cool.

So much minesweeping to be done. Let’s try react using NPM, you can install, create react. App, then use create react app to create a skeleton project. Here I call it hello. World react navigate into the directory where it was created and call NPM start now, navigate to localhost 3000 in your browser and check it out. If you prefer angular install that too, the steps are almost the same again. We use NPM to install at angular slash CLI, create an angular app using ng new.

My angular project change directories into the project folder using CD for change directory. My angular project now ng serve browse to localhost 4200 and check it out here. You’ll notice that I have procs a react, app and an angular app all running on different ports, all on the same Chromebook. I think this is pretty handy. What’s more, this is all local. So as long as your tools are already installed, you could do all of your development offline say like on a plane.

What about docker, no problem again we’re going to follow the normal Linux installation steps. First, we double check that all the dependencies are installed. We add the docker repository to apt and then we update the apt package list. Since we just added a new repository. We use sudo apt update to do this, then install docker test it out by running hello world. This is done with sudo docker run hello world.

You should get a nice mess showing that everything is working. Let’s do something a little bit more advanced by running an Ubuntu Linux container and docker sudo docker run it Ubuntu bash and there you go. Your output is going to look something like this in the Ubuntu container. I’ve taken a look at the OS version with cat, slash et Cie / OS version, and you can see it’s really Ubuntu now, once an app is ready to deploy, it should be tested because Chromebooks have web Android and Linux.

You can test across multiple browsers on multiple platforms: alright, on the same device, let’s install a whole pile of browsers to prove this point using the terminal in apt. You install Firefox for Linux note in debian the package name is Firefox ESR. Then, let’s also install the chromium browser for Linux feeling brave. Let’s install the brave browser for Linux. I won’t walk through all of these lines right now, but again they are just the standard installation instructions for Debian Linux.

We install the GPG key. We install the repo and finally brave now if for browsers, aren’t enough, let’s add a few more head over to the Google Play, Store and install some Android browsers. Let’s go with Firefox for Android opera for Android and Chrome Beta for Android. We now have seven browsers installed, which can give us a reasonable first attempt at test coverage. We have the Chrome, OS Chrome browser three Android browsers, that is Firefox Chrome, Beta and opera, three Linux browsers Firefox for Linux, brave and chromium, and here you can see that our procs web app is running on all seven one.

Last thing to mention in case you have a mobile app that interacts with your web service. You can do Android, TBWA and flutter development on Chrome OS devices, which means you can build and package your mobile app on your Chromebook test it right on the device. You were coding on, like any other Android app build your web component, start your web server and then test everything on multiple browsers and see how it interacts right on the device.

Android studio is as easy to install as visual studio code or atom head over to the Android studio site and download the dot de Bie file. Then you can code. Your app like you’d expect an Android studio with one cool difference: you’ll notice that you can push directly to the Chromebook you’re working on pretty cool full instructions on how to set this up can be found on the link. At the end of this article on the android page, so with your chromebook, you can build web apps with the tools you are used to develop and test right on device with tools like nodejs docker and angular tests across multiple browsers, including mobile, browsers and even test Mobile app and web interaction right on device, and all of this could even happen offline like on a long flight.

So now, don’t you agree. Chromebooks are awesome, as promised. Here is a link to a guide to get your Linux environment customized. Just the way you like. It’s cross dot, page dot, link slash web dev. Thank you can’t wait to see what you build.
