Flask vs Lumen: What are the differences?

Introduction

Flask and Lumen are two popular web frameworks used for building web applications. Although they have similarities, there are key differences that set them apart.

Routing: Flask uses decorators to define routes, allowing developers to specify functions to be called when a particular URL is accessed. Lumen, on the other hand, uses a routing syntax that defines routes in a separate file. Routes in Lumen are defined using the Route::get or Route::post methods, making it more explicit and organized.
Size and Simplicity: Flask is known for its simplicity and lightweight nature, making it easy to learn and use. Lumen, on the other hand, is designed to be a micro framework that focuses on speed and minimalism. Lumen has a smaller footprint compared to Flask, providing faster performance and reduced resource consumption.
Community and Ecosystem: Flask has a larger and more mature community compared to Lumen. It has a vast ecosystem with numerous third-party libraries and extensions available, providing developers with a wide range of options for additional functionality. Lumen, being a relatively newer framework, has a smaller community and a more limited set of packages and extensions.
Database Support: Flask supports a wide range of databases through third-party extensions, including popular databases like MySQL, PostgreSQL, and SQLite. Lumen, on the other hand, has built-in support for the Laravel ORM, Eloquent, which simplifies database operations. However, Lumen has limited support for other databases compared to Flask.
Template Engine: Flask uses Jinja2 as its default templating engine, which provides a powerful and flexible way to render dynamic content. Lumen, on the other hand, uses the Blade templating engine, which is the default templating engine for Laravel. Blade offers a more expressive syntax and provides features like template inheritance, making it easier to manage complex views.
Development Philosophy: Flask follows a "micro" philosophy, where it provides a minimalistic core with the flexibility to add additional functionality as needed. Lumen, on the other hand, follows a similar philosophy but focuses on providing a micro framework optimized for building APIs and microservices.

In Summary, Flask and Lumen have distinct differences in terms of routing syntax, size, community support, database support, template engine, and development philosophy.

Advice on Flask, Lumen

Django

Python

Flask

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?

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.

Python

Nameko

RabbitMQ

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.

Detailed Comparison

Flask	Lumen
Flask is intended for getting started very quickly and was developed with best intentions in mind.	Laravel Lumen is a stunningly fast PHP micro-framework for building web applications with expressive, elegant syntax. We believe development must be an enjoyable, creative experience to be truly fulfilling. Lumen attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as routing, database abstraction, queueing, and caching.

What are some alternatives to Flask, Lumen?

ExpressJS

Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.

Django REST framework

It is a powerful and flexible toolkit that makes it easy to build Web APIs.

Sails.js

Sails is designed to mimic the MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with scalable, service-oriented architecture.

Sinatra

Sinatra is a DSL for quickly creating web applications in Ruby with minimal effort.

Slim

Slim is easy to use for both beginners and professionals. Slim favors cleanliness over terseness and common cases over edge cases. Its interface is simple, intuitive, and extensively documented — both online and in the code itself.

Fastify

Fastify is a web framework highly focused on speed and low overhead. It is inspired from Hapi and Express and as far as we know, it is one of the fastest web frameworks in town. Use Fastify can increase your throughput up to 100%.

Falcon

Falcon is a minimalist WSGI library for building speedy web APIs and app backends. We like to think of Falcon as the Dieter Rams of web frameworks.

hapi

hapi is a simple to use configuration-centric framework with built-in support for input validation, caching, authentication, and other essential facilities for building web applications and services.

TypeORM

It supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.

FeathersJS

Feathers is a real-time, micro-service web framework for NodeJS that gives you control over your data via RESTful resources, sockets and flexible plug-ins.
