Web frameworks in Rust

Posted 2020-09-09 20:48. Tagged , , .

When doing a web application server, one of the first things to decide is which “web application framework” or “request handler library” to use. In Rust, there are more alternatives for that question than in most programming languages, and anyone who has ported some code from tomcat jsp to play framework or from flask to django may dread making the wrong choice. On the other hand, Rust being very strict on static typing makes it very easy to do major refactorings, and I have switched existing projects from iron to nickel to gotham to warp myself without too big problems.

Rust and the web in 2018

There is A Call for Community Blogposts over at the Rust Programming Language Blog. This is my entry.

I mainly do “server-based” web service development. The server sends html, css, images, and javascript to the browser. The javascript implements progressive enhancement for the content, but the site should be usable and as nice as possible even with javascript disabled. So while I certainly do RESTful json API:s, I also do server-side html templateing, css (and scss) minification, etc. I think Rust has great potential here, partly because of optimization and execution speed, but mainly because the type safety and fearless concurrency make it easy to actually get things right and avoid unpleasant surprises at runtime.

A compiling template system in Rust

Posted 2016-10-07 18:32. Tagged , , , .

When developing web applications, it is often useful to have a template system. Something that lets you write generic versions of web pages, that the application can fill with the specific content for each page it should show.

There exists lots of “languages” to write such templates, such as mustache, jinja2, and play 2 scala templates (twirl). Most fits very well with a dynamic language, where you can get properties from an object, or even call a method, by its name in a plain string. In a statically compiled language, the actual names of fields and methods are not relevant, and generally not present, after compilation. This makes a “dynamic” template language a hard match for a compiling language such as rust. So why not try to create a better match?

Some ways to log stuff in java

Posted 2013-11-14 15:10. Tagged , , .

Logging in java is a mess. For a long time there was no standard way of logging in java, so there is a lot of 3:rd party solutions. Apache commons logging, slf4j, and log4j are probably the most used.

By now, there is standard java.util.logging package, but most people stick to the old 3:rd party solutions. As we shall see, that isn’t really surprising, since java util logging kind of sucks.

I have done some exploration of different options for logging in java.
