Thousands of users on day 1: Prototype to Production in the Javascript orldRecently, my friend talked to me about a golden startup opportunity that he was considering. His client was ready to advance the cost of the development for an app that my friend would build but would also keep ownership. That is simply the perfect starter for SaaS business.Unfortunately, my friend isn’t a programmer and he was looking for advice to build a development team. My first reaction was to tell him that he probably only require an MVP and that I can definitely do it for him. That will buy him some time to build a team and he will already get the ball rolling with users and (potentially) revenue from the app. Best of both worlds, right?After years of building hundreds of side projects, here’s how I (...)

I love Ruby and I love Rails, but I’ve found myself searching for something more. Something fast so I don’t need to add caching. Something type-safe so customers see fewer bugs. Something fun to use so I actually enjoy building applications.Would Elixir scratch my itch? It was a good start. It made it fun to write beautiful code, but I still encountered bugs in production that could have been caught with a better type system.There’s Elm. It’s beautiful. Fun. But only available on the front-end.I played briefly with Go and Rust, but I felt like the type-system and syntax was too unfriendly for me to enjoy using them.Finally, I tried CrystalAt first, I was pretty put-off by Crystal.

As a full-fledged web framework, #ror offers many components of a successful web project, such as an ORM (Object Relational Mapping) system for business data and logic, routing, and application management out of the box. Still, to decide whether RoR is a good fit for your project, you need to know what makes this framework different from others. To help you build a deeper understanding of RoR, we are (...)

Let’s face it, nowadays, even the most complex web development tasks are expected to be written in JavaScript. Having said that, the consistently changing landscape of JavaScript is confusing and makes productivity difficult. And it is not as if JavaScript is the most user friendly language in the world. JavaScript is as popular as it is because it has always been a necessary evil in frontend web development.However, there was a time where JavaScript only existed to be sprinkled into your frontend to make it feel more dynamic. In recent years, in a search for perceived performance, large corporations began writing the crux of their applications in JavaScript in the frontend. This considerably shrunk the requirements for backend work in these applications. It is no secret that many (...)
