I am a freelancer, I need to develop a full stack app for a client. The frontend will be an SPA. The backend will be an API that makes calls to generative AI so I would like to use LangChain (or LangChain4J). I have more experience with Java/Spring Boot, but Python seems the best fit since its using AI and allows for simpler/more rapid development. I will be the lead developer on this project, aided only by a junior dev. My question is : how robust and production-ready is FastAPI ? I'm not interested in performance, I want the software to work well, be robust in production and scalable.

Since you're a frontend dev, you have experience working with async processes. ASP.NET Core is reactive (async) by default, giving you a higher throughput out of the box. You can do the same with Spring Boot Reactive, but it's less common. Typescript knowledge will get you comfortable with any OOP language, so both C# and Java should be fairly easy to work with. Then you should research what you would like to do with backend skills : do you want to work at huge corporate (Java) vs government (C#) vs startups (C# or Node.js) ? Do you want to work as an employee or a freelancer ? Check out what are the job opportunities in your area. Then you can choose what's best for your future goals.

Thymeleaf is the way to go. Compared to JSP it is more elegant and less cumbersome. Plus you can render your Thymeleaf templates statically in the browser and it will look good even without a web server. With Spring Boot, Thymeleaf is the recommended way and works out of the box without any additional configuration.

Hello Daniel, As someone who already knows Vue.js you will find Nuxt is powerful and gives you many options as you can use it to make a static site, SPA or SSR (universal) application. It is also very easy to get started with. It is a framework gaining lots of traction lately (over 1M downloads last month) so you can have confidence that it is worth trying. I developed my simple portfolio site with Nuxt and I had a lot of fun. In essence, I find it perfect for simple projects.

Hello, I am a fullstack web developer. I have been working for a company with Java/ Spring Boot and client-side JavaScript(mainly jQuery, some AngularJS) for the past 4 years. As I wish to now work as a freelancer, I am faced with a dilemma: which stack to choose given my current knowledge and the state of the market?

I've heard PHP is very popular in the freelance world. I don't know PHP. However, I'm sure it wouldn't be difficult to learn since it has many similarities with Java (OOP). It seems to me that Laravel has similarities with Spring Boot (it's MVC and OOP). Also, people say Laravel works well with Vue.js, which is my favorite JS framework.

On the other hand, I already know the Javascript language, and I like Vue.js, so I figure I could go the fullstack Javascript route with ExpressJS. However, I am not sure if these techs are ripe for freelancing (with regards to RAD, stability, reliability, security, costs, etc.) Is it true that Express is almost always used with MongoDB? Because my experience is mostly with SQL databases.

The projects I would like to work on are custom web applications/websites for small businesses. I have developed custom ERPs before and found that Java was a good fit, except for it taking a long time to develop. I cannot make a choice, and I am constantly switching between trying PHP and Node.js/Express. Any real-world advice would be welcome! I would love to find a stack that I enjoy while doing meaningful freelance coding.
