It is based on standards: OpenAPI, JSON Schema and OAuth 2.0.
Specs
Question Ranking
Pros
Pro Enhanced productivity and less timewasting
The application can be run and debugged from the IDE without the need to recompile or redeploy the WAR file. This is because a Dropwizard web application creates on main program which starts the jetty container.
Pro Application metrics integrated into the framework
Dropwizard comes with application metrics integrated out of the box. These metrics provide a lot of useful information such as request/response time.
For example, to get the execution time of a method, the @Timed annotation is used.
Pro Quick project bootstrap
Starting a project with Dropwizard si very easy and bootstraping is quick and painless. All that's needed is a single dependency added in the pom.xml file and it's ready to go.
Pro Standards
It is based on standards: OpenAPI, JSON Schema and OAuth 2.0.
Pro Dependency injection
It has a simple but powerful dependency injection system, it can be used to handle authentication, per-user rate limiting, authorization controls (e.g. with roles), etc.
Pro High-performance
It's based on Starlette and Pydantic, so, it's one of the fastest Python frameworks.
Pro Editor completion
It is based on Python type declarations, so, editors and tools can give great support. Including type checks and autocompletion everywhere.
Pro Automatic docs
It generates interactive API documentation automatically from your code.
Pro Database independent
It's independent of database or ORM, but compatible with all of them. Including relational databases and NoSQL.
Pro Async IO / optional
It's based on Async IO, which gives it high concurrency. But you can use non-async libraries and it runs them appropriately.
Pro World class documentation
It has some of the best documentation of any framework.
Pro WebSockets
Because it's an async framework, it can handle async-native protocols like WebSockets.
Pro OAuth 2.0
It has integrated support for OAuth 2.0. Including declaring required scopes per endpoint. So, you can easily integrate it with external OAuth 2.0 providers or build your own with it.
Pro Background tasks
Included support for background tasks, thanks to being based on Starlette.
Pro Data validation
It validates the data using the types you declared. Even in deeply nested JSON requests.
Pro Fast is really fast (!)
It's easy to develop API based applications in Python on deadlines for Android and IOS Development.
Pro One of the fastest growing communities
Pro Supports GraphQL
Python's graphene library is included as an optional dependency meaning that GraphQL API's are supported out of the box, with no additional tweaking needed.
Cons
Con Does not allow a lot a freedom of choice
Dropwizard removes a lot of freedom that the developer may have with other frameworks because of the fact that it tries to do everything itself. It chooses the best Java libraries for the job required, without allowing the developer much choice.
Con Smaller community
Since FastAPI is relatively new, its community is smaller than Django Rest Framework. But it can grow with time.
