Hi,
https://mach3db.com is now a frontend to search Wikipedia and Stack Overflow article titles.
Right now I only have simple substring search to reduce load on my server.
The results are clickable links that point to lightweight versions of Wikipedia and Stack Overflow articles.
Please give it a try!
It works best in the Vivaldi browser: https://vivaldi.com/
Stack Overflow results can also be filtered by minimum number of comments.
Please email [email protected] if you are interested in our blazing fast PostgreSQL compatible hosted database solution.
We also offer NocoDB (https://nocodb.com/) and Grist (https://www.getgrist.com/) high speed hosted instances.
Thanks!

When creating this template project, I saw that I had to set up the server manually and I used gofiber as it has express-like functionalities, and as a MERN stack developer, I found it very easy to use. Once I thought to make a server-project generator in Express as well, but they already have one, it is called express-generator. Then I thought there might be the same thing for Fiber as well. But when I searched in GitHub with the topic:go-backend-template, I only found pre-made templates that you can clone and use for your projects. That's when I decided to give it a shot.
