Flask vs Mojolicious: What are the differences?
Key Differences between Flask and Mojolicious
Introduction
Flask and Mojolicious are both web frameworks that are used to develop web applications. However, they have some key differences that set them apart from each other. In this article, we will explore these differences in detail.
Routing Mechanism: Flask uses decorator-based routing, where the routes are defined using special decorators on top of the view functions. On the other hand, Mojolicious uses a more traditional route definition approach, where routes are defined in a separate configuration file or within the application itself.
Templating Engines: Flask uses Jinja2 as its default templating engine. Jinja2 is known for its flexibility and powerful feature set, and it allows developers to write complex templates with ease. Mojolicious, on the other hand, uses its own integrated templating engine called Mojo::Template. While both templating engines are powerful, Jinja2 has a larger community and ecosystem.
Middleware: Flask provides a middleware called "Werkzeug" which includes various features like request/response manipulation, cookie handling, and exception handling. Mojolicious, on the other hand, has its own built-in middleware system called "Mojolicious::Middleware" which provides similar functionality. The main difference lies in the implementation and integration with the respective frameworks.
Size and Dependencies: Flask is a lightweight framework with minimal dependencies. It provides a basic set of features but allows developers to add additional functionality through various extensions. Mojolicious, on the other hand, is a more feature-rich framework with a larger codebase and more dependencies. It provides a comprehensive set of features out of the box, reducing the need for additional extensions.
Async Capabilities: Mojolicious has built-in support for asynchronous programming, allowing developers to write non-blocking code using promises, delayed responses, and event-driven architecture. Flask, on the other hand, does not have native support for asynchronous programming. While asynchronous programming can be achieved in Flask using external libraries, it is not as seamless as in Mojolicious.
Community and Documentation: Flask has a large and active community with extensive documentation and a wide range of third-party extensions and libraries available. It has been around for a longer time and has gained a solid foothold in the Python web development community. Mojolicious, on the other hand, has a smaller community and documentation base compared to Flask. It is more popular in the Perl community and may have fewer resources available.
In summary, Flask and Mojolicious differ in their routing mechanism, templating engines, middleware, size and dependencies, support for asynchronous programming, and community/documentation resources.
Hey! So I am planning to make an e-commerce website with React Native as my frontend technology stack and MongoDB as my database. I was wondering what will be the best REST framework to use for my backend that will simply serve the frontend. Is Django rest framework a good option or should I go with Flask? I am currently leaning towards flask as the development team is well versed in it. Please help!
If the application is simple such as less endpoint or simple logic, I'd suggest Flask. But what you're building is quite a large system that contains many logics and a lot of models. So I'd suggest you with Django and Django REST framework. Django ORM is also one of the best ORM in the world as well.
FastAPI is modern microframework. If you haven't used any of them, I'd suggest FastAPI. Django REST is also good if you have previous experience with it.
My journey to developing REST APIs started with Flask Restful, and I've found it to be enough for the needs of my project back then. Now that I've started investing more time on personal projects, I've yet to decide if I should move to use Django for writing REST APIs. I often see job posts looking for Python+Django developers, but it's usually for full-stack developers. I'm primarily interested in Data Engineering, so most of my web projects are back end.
Should I continue with what I know (Flask) or move on to Django?
If you want to be a Web developer with knowledge in another frontend and NoSql technology, maybe continue with Flask. However, if you want to create very fast solutions to grow up with a new business and merge these with data analysis and other tools, Django is the answer. Basically read more about the service architecture where you feel more comfortable, Microservice or Monolithic, but please will not married with any because they solve issues to different contexts.
Which is the best Python framework for microservices?
We are using Nameko for building microservices in Python. The things we really like are dependency injection and the ease with which one can expose endpoints via RPC over RabbitMQ. We are planning to try a tool that helps us write polyglot microservices and nameko is not super compatible with it. Also, we are a bit worried about the not so good community support from nameko and looking for a python alternate to write microservices.
Bottle is much less bloated and fast. Its built-in templating system is one of the fastest as it compiles the templates in bytecode. Also Bottle has no depenencies, preventing dependency bloat.
I have just started learning Python 3 weeks ago. I want to create a REST API using python. The API will be used to save form data in an Oracle database. The front end is using AngularJS 8 with Angular Material. In python, there are so many frameworks to develop REST APIs.
I am looking for some suggestions which REST framework to choose?
Here are some features I am looking for:
Easy integration and unit testing, like in Angular. We just want to run a command.
Code packaging, like in java maven project we can build and package. I am looking for something which I can push in as an artifact and deploy whole code as a package.
Support for swagger/ OpenAPI
Support for JSON Web Token
Support for test case coverage report
Framework can have features included or can be available by extension. Also, you can suggest a framework other than the ones I have mentioned.
For starters flask provides a beautiful and easy way to create REST APIs. Also its supported by excellent beginner docs as well as a very active community. Another good thing with Flask is its widely available list of plugins which allow you to build as you go. Its also good in performance and can scale to a quite decent level. However, if you are sure your project is going to be fairly big, it would be better to start with Django as it provides a lot of features out of the box and is extremely stable in performance. Both these frameworks have support for Swagger, JWT, Coverage Report although you have to install plugins for them. Deploying both of these are fairly simple and there is huge documentation available. Django has one of the best documentations I have come across. I hope I was able to answer your queries.
We decided to expose our small machine learning (ML) pipeline as a REST API. This allows us to nicely separate concerns from the rest of the codebase. There are two very popular choices in Python for building APIs: Flask and FastAPI. We have experience with both, but find that FastAPIs use of static type hints and validation with Pydantic allow us to build better APIs faster.
