The most important programming-style and architectural decisions I make as a frontend (or full-stack) developer building a complex application: TypeScript types are the glue that holds the application together and ensure changes can be made quickly later…

I used to host the web app (SQLAI.ai) on Vercel and still do, but I moved the “app” portion to Cloudflare, given the much broader feature set and significantly lower price.

Partytown is a library dedicated to offloading third-party libraries such as tracking scripts to a web worker, i.e. downloading and executing them in the background.

The main advantage of server-side applications is that you can render large parts of applications on the server, where there is already access to the database and other configurations that do not exist on the user side without building an API logic.

If you want to use Gemini’s public API, but at the same time have a safe fallback in case you have exhausted the rate limits, you can use the OpenAI TS/JS library and a few helper functions.

Received a complaint email from Amazon SES (Simple Email Service) pointing out that my SES account could be closed because the complaint rate exceeded 0.51%.

If you want to keep your hosting costs low and not be forced to take the steep path from “Hobby” to “Pro”, avoid NextJS’s ‘Image’ component.

When I started building my application I used a routing-based structured and as the application evolved I transitioned – at least partially – to a domain-driven structure.

By default NextAuth authenticates the domain provided by the NEXTAUTH_URL environmental variable and if it is on a sub domain like www.example.org also all domains below www like subdomain.www.example.org or subdomain.subdomain.example.org.

After adding an embedded video to the landing page of my app I noticed bandwidth usage rose dramatically.

Burnout is a modern euphemism for exhaustion depression.

In most examples I know, if not all, OpenAI uses English.

Site search enables you to search on various sites directly from the browser’s search bar.

I Started a small bootstrapped startup in the aftermath of corona after being stuck in home office for, well, years.

Next.js has become not only the leading framework for building React-powered web apps but also a simple way to develop and deploy JavaScript applications with less manual configuration.

Server components enable you to render the entire pages on the server without messing around with API endpoints and data fetching logic.

Limiting OpenAI’s token usage isn’t merely desirable because it is cheaper and faster, but also because it increases the size of the overall context.

While I was building aihelperbot.com I did what I imagine many developers do: I used an ORM for everything database related.

I wanted to add markdown blog to my NextJS app.

What does it cost to host a small web app on Render vs Digitalocean with Render’s new pricing model?

Render adopted a new pricing scheme for its services on 1st of January 2023.

I was checking the performance of one of my web sites using Page Speed and noticed it complained about assets loading slowly as well as the initial response time from the server being a bit long (500ms-700ms range).

I had no idea what would happen to me that day.

Sublime Editor is build for writing and reading code.

Redux is a popular library used to manage global application state, at least the claim.

It’s that time again where I have to prepare for job interviews.

Originally the plan was to get familiar with Next.js and Prisma by making a simple boilerplate for it.

Hiding or showing a element with React is as simple as an if statement deciding whether to print it or not.

Features that allow users to fire multiple requests quickly — where only the latest request is relevant — should include an AbortController.

Although it is clearly not in fashion at the moment, deploying websites on a VPS (virtual private server) or regular server for that matter, without any containerization and orchestration is both fast and easy.
