Getting the Current URL in Next.js Server Components

Streamlit Authentication

Streamlit Authentication

Streamlit is a powerful tool for creating “data apps.” The easiest way to understand it is with this picture (from Streamlit’s marketing site): You write python code ⇒ You get an interactive web application.

Becoming a Dungeon Master for an Interview

Becoming a Dungeon Master for an Interview

Interviews should be as close as possible to the work that the candidate would do if they join. While that seems like a pretty tautological statement, it is unfortunately not always true. When interviewing as a software engineer, for example, you’ll run into places that lean heavily on algorithms

Writing Clean Code with FastAPI Dependency Injection

Writing Clean Code with FastAPI Dependency Injection

Before anyone else read the code that I wrote, “clean code” wasn’t really a thing for me. I had no issues reading my code because, well, I wrote it. That was also pretty true for me in college as well. Classes rarely worried about the readability of code -

Why we still use React HOCs

Why we still use React HOCs

If you’ve integrated with our React library, @propelauth/react, you’ve probably seen that we offer a pretty standard React hook useAuthInfo. It returns a few important pieces of information like: * isLoggedIn - whether or not the user is logged in, as you probably already knew * user - the

Define Your Own User Schema

Define Your Own User Schema

What information do you want to collect from your users? Maybe you want to find out how they first found out about you. Maybe you want them to agree to your terms of service. Or maybe you just want to know their name so all your marketing emails don’t

The Joy of Pointless Projects

The Joy of Pointless Projects

When I was a kid, I learned how to code with QBasic and VB6. One of the first projects I ever had someone else use was... if we are being polite, a password manager for my dad. If we are being realistic, it was a small script that opened up

5 Common Pitfalls with Server Components in Next13 (with examples)

The App Router is a new feature in NextJS 13, and it was recently switched to being the recommended option when you create a new NextJS application. This effectively replaces the Pages Router, and NextJS has documentation on how you can incrementally switch over. The most notable difference in the

Who can sign up for your product?

At PropelAuth, we believe that your authentication requirements will change over time. The features you need when building your MVP are very different from those you need as a Series C company. One of the best examples of this is how you handle signups. So let's look at
