Hello everyone and welcome to another round of Front-End News.
- Is your code ready for Android 10?
- Mozilla releases Firefox 69
- We’ll talk about best practices for publishing an NPM package…
- and what cool things you can do with browser developer tools
Next, I have some conference-related info, the usual software updates section, and the new Developer Of The Week. So stay with me until the end to find out all the details.
As always, I have also prepared a video version for those that prefer listening instead of reading. If you enjoy this format, I would appreciate it if you would subscribe to the YouTube channel as well.
Is your code ready for Android 10?
Android 10, the latest version of Google’s operating system, became available this week on 3rd of September. The updates already started rolling out for all Google Pixel variants. The rest of partner devices should receive these updates by the end of the year.
For the first time in a while, Google didn’t choose a dessert name for this edition of Android, moving instead to a simpler numerical naming scheme. This is part of a process that redesigned the Android identity, including a new logo and color palette. The little green droid lost his body, in exchange for a more expressive head, that is now always next to the Android wordmark.
The changes this new version brings are many and not exactly the subject of this channel. What matters for developers is whether their apps will continue working on the new platform and what upgrades they will have to perform to make use of the newest features that are now available. You can find a handy guide for the process in the official release article.
Some of the new features that you will have to include are the support for Dark Theme, the new gesture navigation system or the optimization for foldable devices. There are also changes and updates for the notification system, use of biometrics, use of codecs or improved networking APIs.
So don’t waste any more time and start checking your code. The latest Android version is already out there for the Google Pixel owners and will come soon to the rest of compatible devices.

Firefox 69 has been released
Developers can also enjoy new debugging features, including console message grouping, event listener breakpoints, and text label checks.
Starting with Firefox 69 you can now use the new
overflow-inline properties which control the overflow of an element’s content in the block or inline dimension respectively. Depending on the
writing-mode property, they map to the existing
overflow-y properties. This makes the content easier to localize, especially when adapting to languages using a different writing direction.
There are also a lot of interesting goodies that were added to the developer tools:
- you can now use event listener breakpoints or you can step through async functions;
- console messages can now be grouped;
- selecting an item to inspect will display in the info bar if that object is a flex or grid item…
- and the accessibility inspector now allows you to check for text labels.
More details are available in the official blog notification and the release notes linked below:
Best practices for publishing an NPM package
I don’t often mention individual articles and tutorials. But this one is a valuable exception — and it might as well be considered a developer handbook in its own right. It is available on the pathof.dev website, but I wasn’t able to find the name of the author (just their GitHub handle).
The article is a comprehensive guide on the best practices for creating and publishing a new npm package. It is divided into several sections, each covering an important step of the process. You learn how to set up your new package, how to write your code and how to build the module. There are also indications on the things you have to do before publishing, the publishing process itself and the maintenance needed after your module becomes publicly available.
This looks like something that should be on the reading list for both aspiring and seasoned maintainers. And if you do read it, please let us all know what you think about it.
Cool things to do with developer tools
Debugging TypeScript in Firefox DevTools
What’s New In Chrome 78 DevTools
Google Chrome developers continue their series of articles dedicated to the new features that will come in future versions on the Chrome Developer Tools. The newest entry is aimed at version 78 of Chrome.
Here are the main features that will be available:
- You can now use the Audits panel in combination with other DevTools features like Request Blocking and Local Overrides.
- The Background Services section of the Application panel now supports Payment Handler events.

These changes are already available in the Canary release of Google Chrome that you can install and run in parallel with the latest stable version.
This summer was a prolific one for industry events. And this week two of these events published their presentations on YouTube. So, even if you were not able to attend, you can now binge-watch all the talks.

The Developer of the Week
This episode the title of Developer of the Week goes to Chris Coyier. Chris is a web designer and a developer and got his first claim to fame with CSS Tricks. It started as a blog about how to build websites, it grew over time into an entire ecosystem.
I’m not sure even he knows how many articles he wrote so far, not only on CSS Tricks and CodePen but on many other websites, magazines, and blogs. The list of interviews alone is several pages long. Chris also speaks and runs workshops at events all over the world like An Event Apart, Smashing Conf, and Webstock.
Chris got his name on the cover of two books. He’s a co-author for “Digging into WordPress”, together with Jeff Star.
The second one, “Practical SVG”, has been published by A Book Apart and it can teach you techniques for a solid workflow, from software basics to build tools to optimization.
Along with Dave Rupert, Chris is the co-host of a podcast called “ShopTalk”, a show about (you guessed it), building websites. He is also a frequent presence on “CodePen Radio”, a podcast all about what it’s like running a small web software business. The good, the bad, and the ugly.
Chris is a very positive person. He thinks the web is an incredible, inspiring, and empowering place and helping people know it better is good for everyone. So go and check his blog, his Twitter profile, and his podcast to get your dose of optimism.
Question of the Day
Do you have a CodePen account already? If not, why don’t you?
