Common tasks in web development

Here is a list of common tasks you typically do when building a web application. This list is useful if you want to master web development (the better you are at more of these things, the more well-rounded you’ll be as a web developer). It can also be useful to compare how different web frameworks (e.g., Laravel, Ruby on Rails, ASP.net, Spring MVC, Django, etc) handle these things.

• Routing requests to code.
• Running middleware to deal with requests (e.g., authentication, rate limiting, logging, A/B testing).
• Rendering HTML using a templating language (e.g., Laravel Blade, Twig, C#’s Razor, Nunjucks)
• Validating incoming HTTP requests.
