amandeepmittal / react-native-examples

📱 A repo that contains React Native & Expo examples, mostly related to articles & tutorials I publish on my blog.

React Native Examples

Why react-native-examples

I am passionate about React Native and Expo ecosystem and one thing I often struggled with is the lack of resources when I was getting started. My another passion is for writing and I though why not combine these two and see how it goes.

I write about React Native and Expo form of blog posts, and tutorials on my personal blog amanhimself.dev and sometimes for other external publications such as LogRocket, freeCodeCamp, Sentry, and Jscrambler. This repository is a collection of examples created for those blog posts.

With time, it gets harder to maintain different repositories, update the code and dependencies (and trying to match up with the speed of ever-changing ecosystem). Thus, I decided to keep all of projects/exmaples that are mostly code examples used in these various tutorials in one place and hence, this repository.

It's completely free. If you find anything useful in this repo, go ahead pick up any code snippet, use it in your own way.

You may find some of the examples being outdated in time, in terms of framework updates or libraries. Don't worry the concept would be the same. Feel free top up an issue or a PR if you feel like somethings needs to be changed.

To keep me caffeinated, you can buy me a coffee too ☕️
