Since 2017, over 50% of web traffic has been caused by mobile devices. This tends to increase in the future as the number of mobile phone users keeps growing. To cater to this user base, Mobile-First Design has been a paradigm shift in the developer community since early 2010.

In a previous article, I gave a couple of tips to improve developer productivity using Chrome Dev Tools. Today, my focus is on how to leverage Chrome Dev Tools to build efficient mobile-first web apps.

Two things to keep in mind:

1. All items in that list, other than the fifth one (“Remote Debugging”) are ways to simulate mobile on a desktop. As you know, simulation is not identical to the real thing.
2. Modern web apps are built component-first. That means we optimize components — not apps. I recommend you use tools like Bit (Github) to build, share, collaborate, and manage independent/reusable components. This will make sure you use tested and optimized components in all your projects.
