Open Source

This page lists some of the open source packages and repositories I have published or contribute to.

Most of them are published under my company 47ng.

Frontend#

My tech stack of choice is Next.js and Chakra UI.

Next.js makes it super easy to build static or dynamic webapps, depending on what is needed.

Chakra UI offers accessibility out of the box with great default styles, that are easy to override thanks to the styled-system approach.

47ng/chakra-next

Opinionated design system for React, based on Chakra UI + Next.js, written in TypeScript.

I wrote an article about how I came to build session-keystore:

End-to-end encrypted applications use cryptographic keys that don't leave the client, so how do we store them securely in the browser ?

Environment Variables#

The Twelve Factor App model uses environment variables extensively for configuration and passing runtime data to a web app.

However, there are things to look out for when working with environment variables, so I built a few packages to make their management easier and more secure:

47ng/redact-env

Redact values of critical environment variables in a string
