Conclusion and extra resources

In 12 videos we cover environment variables in back end node, front end react, and mobile react native. You'll learn when environment variables are not even the best solution for configuration and how to test them.

Every time I used to build a new project it seemed there is a different strategy you have to come up with to manage configurations.

When I heard of dotenv and how common it was I figured that a standard would be simple to setup and consistent, but when I started using it felt like I had to re-invent the wheel every time.

After building hundreds of apps from scratch, consulting with people all over the industry, and answering countless questions to users of my open source libraries, I discovered that there's only a few patterns you need to know to be able to configure any app from scratch securely in a team.

In this course I'll show you the patterns for configuring any Javascript project to be secure and robust in team settings using environment variables.

At this point, I'm confident you can take the patterns we discussed and use

I hope you learned a few things about the underlying tools and how they work,

how their environments work, and for things that you haven't tried before.

So with that, this is the last video in the course. It's been really fun

diving deep into data in such a fundamental concept, and I hope it's been fun

But there's more to it. This course only focuses on core JavaScript usage of D

but the patterns are extensible to others, and most programming languages

There's lots of great resources out there, such as the DAWN.org blog, and the
