I’ve been working at this little web app for a bit over a week and thought I’d share what I’ve discovered.

PS: I’m looking for work!

About The Project

Check out a video demo!

I decided to undertake this project because I wanted to prove to myself and possible employers that I can quickly adapt to new tech stacks and create working prototypes.

Ultimately, I think I accomplished that goal.

Unfortunately, I failed to see just how detrimental some of the choices I was making would be when actually creating a working web app.

Here’s why:

• Deno is an incredible javascript runtime. It even support npm modules. However, it barely supports npm modules. Many of the things I tried simply did not work.
• Deno Deploy is an awesome service for deploying your deno based apps. Unfortunately, it does not support Deno’s npm: specifier. The feature that allows you to load commonjs npm modules.
• Because Deno Deploy did not work, and I wanted a live demo of my web app, I had to spend countless hours researching and testing alternatives. This was not productive.
• Many Node.js libraries and frameworks that appear to function end up having issues down the line This meant that I had to redo entire sections of the app when a specific things suddenly wouldn’t work in my Deno environment.
• Database drivers, query builders, and ORM’s are still kind of underdeveloped for the Deno runtime. My initial plan was to use Prisma, but for reasons stated above, it didn’t work out. Instead, I opted for Mongoose. I’ve never used MongoDB and still have very little idea how it actually works.
• Preact is awesome, and this project only made me love it even more. The problem is that when I use a React based library, I am now using it through two compatability layers: Deno’s npm support, and Preacts compat layer.

Of course, even with all of the above roadblocks, I perservered and stubbornly pushed my way into creating a working web app.

Does this web app scale? Absolutely not. There is no recommendation algorithm for posts. There is no pagination. I have no idea how to scale a MongoDB database, but the way I’m interacting with it right now is for sure not going to scale.

The web app is stateless, and I could load balance between servers without too much concern, but that’s about it.

Is this a good example of a Deno Fresh project? Again, no. This code base is filled with repeated code, too much interactivity, and not enough thought towards its architecture. If I were to start over with Deno Fresh and only Deno based modules, I think I could do a much better job of leveraging Deno’s “ship no javascript by default” approach. As it is now, almost every component is an island. That’s definitely not using Fresh as intended.

When making this project, I heavily referenced “Code with Antonio’s” twitter clone. His clone was made with Node, Next.js, and Prisma.
