Flask vs Go: What are the differences?

Flask and Go are both popular frameworks used for web development. While Flask is a Python microframework, Go is a statically-typed, compiled language. Although they are both used for building web applications, they have some key differences.

Ease of Use: Flask is known for its simplicity and ease of use. It has a small learning curve and provides a flexible and intuitive interface for web development. On the other hand, Go requires a deeper understanding of programming concepts and may be more challenging for beginners.
Concurrency: Go is designed to handle concurrency efficiently. It has built-in support for goroutines and channels, which allow for concurrent processing and communication between different parts of the code. Flask, being a Python framework, relies on the Global Interpreter Lock (GIL) and does not provide the same level of concurrency as Go.
Performance: Go is known for its superior performance due to its compiled nature. It can handle a high number of concurrent requests efficiently, making it a good choice for building scalable web applications. Flask, being interpreted, may not perform as well as Go in high traffic scenarios.
Ecosystem: Flask has a large and active community, with a wide range of third-party libraries and extensions available. It integrates well with various Python tools and frameworks, making it highly customizable. Go, although not as mature as Python, has a growing ecosystem with libraries and frameworks specifically designed for web development.
Development Speed: Flask allows for rapid development due to its simplicity and ease of use. Python, being a high-level language, enables developers to write code quickly and efficiently. Go, while efficient, may have a steeper learning curve and may require more time for development.
Static Typing: Go is a statically-typed language, which means that variable types are checked at compile-time. This can help catch errors early and improve code reliability. Flask, on the other hand, is dynamically-typed, which allows for more flexibility but may also introduce errors during runtime.

In Summary, Flask and Go differ in terms of ease of use, concurrency handling, performance, ecosystem support, development speed, and typing system. Flask is more beginner-friendly, while Go offers better performance and concurrency handling.

Advice on Flask, Golang

Ido

Mar 6, 2020

Decided

When developing a new blockchain, we as a team chose Go lang over Java and other candidates, due to Go being (a) natively suited to concurrency - there are primitives in the language itself (goroutines, channels) that really help with reasoning about concurrency (b) super fast - build time, running, testing are all much faster that Java, this gives a far superior developer experience (c) shorter and stricter than Java - code is much shorter (less verbose), and there is usually one good way to do things, and even the code formatter that is bundled with Go is very opinionated - over a short time this makes reading other people's code far smoother than having to deal with different styles.

You should be aware that Go presently (v1.13) lacks Generics.

We decided to use python to write our ETLs and import them into metabase via a lambda. Before python we tried using Go, but overall go was way more verbose than Python when writing the ETLs. Go also had some issues managing memory when using the S3 upload manager library. This was a deal breaker for us that made us switch to Python.

In the end the solution was much cleaner and maintainable.

PHP is easy to learn and you can get up and running in no time, available on almost all hosting providers and you can find developers easily. It has some great frameworks for building your backend like Symfony and Laravel. However, it can be challenging when running an enterprise and needs some adjustments, very recommended for starting a new project or startup.

Detailed Comparison

Flask	Golang
Flask is intended for getting started very quickly and was developed with best intentions in mind.	Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

What are some alternatives to Flask, Golang?

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Java

Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

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.

Scala

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.
