While working on a website I was loading an image dynamically based on the current page URL.

Being sure I’d eventually forget to create an image in the future, I looked into avoiding the usual “broken image” that says “this website is abandoned”.

The technique I used is this:

<img src="/{{$bookname}}.png" onerror="this.remove()" /> TIP: this inside an inline event handler in HTML refers to “this element” Sure, the optimal way is make sure images are always working. And that’s not optimal from many points of view. But that’s a workaround that uses the platform features because I know I might not pay attention to that as I’m a solo developer and I might have a broken image visible for weeks before I realize. Another thing you could do is display a fallback image, if you need, in this way: <img src="/{{$bookname}}.png"
onerror="this.onerror=null; this.src='fallback.png'"
/>

this.onerror=null here is needed so there’s no “infinite loop” if the fallback image is not found.

## One more thing! ⚠️ ✋

At the end of January I will organize the Web Development Bootcamp.

It's a 10-weeks long cohort online course where I will guide you to becoming a Web Developer.

It's not "just a course". It's a big event I organize once a year.

We'll start from zero, learn the fundamentals of Web Development, HTML CSS, JavaScript, Tailwind, Git, using the command line, VS Code, GitHub, Node.js, we'll then learn React, JSX, how to use PostgreSQL, Astro, Next.js, Prisma, deploying on Netlify/DigitalOcean/Fly/Vercel and much more!

At the end of the first 10 weeks you'll know how to create web sites and web applications and I'll unlock you the 2nd phase of the Bootcamp: you will get access to a large number of projects exclusive to the Bootcamp graduates, so you can follow my instructions to build things like private areas with authentication, clones of popular sites like Twitter YouTube Reddit, create e-commerce sites, and much much more.

Because once you got the fundamentals, you only learn by working on real, exciting projects.
