For HTTP, this includes both route handlers and middleware, but a Service doesn’t have to be specific to HTTP.Ī middleware, then, is a special case of a Service that does some work and also calls another Service, which may be another layer of middleware or the endpoint handler. First, let’s take a step back and understand more generally what a Service represents.Īctix’s Service represents anything that takes a request and returns a response. So we need a Transform, a Service, and maybe an extractor, but how do they fit together? For many middlewares, most of the complexity turns out to be boilerplate, but it still helps to understand what that boilerplate is actually doing. In actual use, this makes very little difference. The primary difference from actix-web 3 is that the Transform trait used to have an associated Transform::Request type, but it is now a type parameter on the trait instead: Transform.

In this post I’m using the middleware traits from actix-service version 2, used by actix-web 4.0 which is in beta as I write this. This works for any middleware that can be written as a closure, but otherwise it’s not an option, so let’s continue so we can see what’s happening under the hood. It requires implementing Transform and Service traits to get started, and you might also need an extractor that implements FromRequest to conveniently retrieve any extra data, such as the user object in the JS example above.Īctix provides a wrap_fn helper to make middleware with only a closure, similar to the JS example.

Another nice to have tool is Cargo Watch that lets you watch the file system and re-compile and re-run the app when you make any changes. You need to have a running postgres server and can create a database to follow this tutorial through. In this tutorial we will be using postgresql so follow the instructions to setup for postgres. Please head over to to get started and setup diesel_cli. We will be using diesel to create models and deal with database, queries and migrations. I will assume here that you have some knowledge of programming, preferably some rust as well. Shameless plug: sparkpost is my crate please leave feedback if you like/dislike it.

We are going to create a web-server in rust that only deals with user registration and authentication. Updated to async/await actix-web-2.0, checkout this branch async-version.
