Back-End Web Developer with Flask Salary in 2024

Where is Flask used?

Flask Alternatives

Django

Python-based web framework following the Model-View-Template (MVT) pattern. It's designed for rapid development of complex, database-driven websites.

# A simple Django view
from django.http import HttpResponse

def hello_world(request):
    return HttpResponse("Hello, world!")

• Comes with an ORM


• Robust security features


• Built-in admin panel


• Steeper learning curve


• Monolithic


• Less flexible in comparison to microframeworks

Express.js

A minimalist web framework for Node.js, known for its speed and flexibility. Ideal for building web applications and APIs.

// A simple Express.js route
const express = require('express');
const app = express();

app.get('/', function(req, res){
   res.send('Hello World');
});

app.listen(3000);

• Fast and minimalist


• Huge ecosystem of middleware


• Great for real-time applications


• Callback hell without proper management


• Less opinionated, which can lead to poor structuring


• No built-in ORM

FastAPI

Modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints.

# A basic FastAPI endpoint
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def read_root():
    return {"Hello": "World"}

• Automatic Swagger documentation


• Type checking and validation


• Asynchronous support out-of-the-box


• Younger community


• Smaller ecosystem compared to Flask/Django


• More complex deployment for async capabilities

Quick Facts about Flask

The Birth of Flask: From April Fool's Joke to Web Powerhouse

Believe it or not, our beloved Flask was conjured into existence as an April foolery by Armin Ronacher in 2010. This little sidekick was an offshoot of an elaborate joke about a framework called "Django" which doesn't actually exist (wink). Don't let its humorous beginnings fool you, Flask vaulted from a pun to become the go-to microframework for Python aficionados seeking simplicity and flexibility in their web concoctions.

The Micro in Microframework: Lean but Fierce

Flask prides itself on being minimalistic, yet it's like a Swiss Army knife for web development. Coined as a "microframework," Flask doesn't burden its user with loads of paraphernalia like that bulky rucksack you're asked to check-in at the airport. Instead, it embodies the "bring your own" philosophy. Fancy a database or an ORM? You're welcome to mix and match your own tools and potions, making it the bartender of the web framework realm.

Version Evolution: The Flask Odyssey

# 2010: Flask pops out of the hat, ready to play.
Flask v0.1 – Hello World, literally.

# Fast forward to 2018: Flask gets serious with async support, waving the magic wand of Python 3.7.
Flask v1.0 – Async Almighty

# Here and now: Beholden to stability, nothing shatters this Flask.
Flask v2.0 – Stability Supreme

Top 10 Flask Related Tech

1. 
   

   Python

   
   

   
   Oh, the slithery Python! Not the one you find in the zoo, but the one you cuddle with in your IDE. This programming language is your golden ticket to the magical world of Flask. It's like the bread to your butter, or in this case, the server to your request. Why? Because Flask is a Python web framework, silly! A touch of Python, and you've got yourself a secret potion to web development wizardry.

   Flask

   
   

   
   The belle of the ball, Flask, is lean, mean, and flexible enough to let you lead the dance. It's like a Swiss Army knife for building web applications. With just a few lines of Python, you can conjure up a web server faster than pulling a rabbit from a hat! And what's even better, it plays nice with others—pair it with various extensions, and you have yourself a full-fledged masquerade ball.
   

   from flask import Flask
   app = Flask(__name__)
   
   @app.route('/')
   def hello_world():
       return 'Hello, World!'

   
   
   
   


3. 
   

   SQLAlchemy

   
   

   
   Want to juggle data in your Flask app without sweating buckets? SQLAlchemy is the ringmaster! It's an ORM (Object-Relational Mapper) that lets you chat with your database using Python classes instead of SQL hieroglyphs. Simply put, it's like teaching your app to speak 'database' fluently without the need for an interpreter.

   Jinja2

   
   

   
   Jinja2 may sound like a forbidden martial arts technique, but it's actually the template engine that turns your HTML from stone-cold statues to lively carnival floats. It's like giving personality to your HTML with the help of Python's slick variables and control structures. Express yourself, your way, but with Python's help, of course.
   

   
   


5. 
   

   Werkzeug

   
   

   
   Werkzeug is a fancy German word for "tool," and it's the reliable swiss knife in the world of Flask. This toolkit helps you manage the request and response objects like a pro juggler. Without Werkzeug, Flask would just be flailing around trying to catch HTTP requests with its teeth.
   

   
   


6. 
   

   Flask-RESTful

   
   

   
   When Zuckerbots and your neighbor's smart fridge want to gossip over HTTP, Flask-RESTful is your go-to translator. By turning Flask into a RESTful API superhero, it lets your application understand the lingo of GET, POST, and other HTTP banter. Now, all of your Internet thingamajigs can have meaningful chitchats.
   

   
   


7. 
   

   Git

   
   

   
   Ah, Git, the powerful time-travel machine for developers! With Git, you can hop aboard the "version control" express, keeping a neat history of your Flask project changes. Accidentally turned your code into alphabet soup? No worries! Git lets you zap back to when your code was chef's kiss perfect!
   

   
   


8. 
   

   Virtualenv

   
   

   
   It's a wild, wild world of Python packages, and without Virtualenv, it's a recipe for disaster—it’s like mixing all your potions without knowing which one turns the king into a frog. Virtualenv keeps your Flask app's dependencies in a neat little bubble, preventing the chaos of clashing sorceries or Python packages.
   

   pip install virtualenv
   virtualenv myenv
   source myenv/bin/activate

   Flask-SQLAlchemy

   
   

   
   Flask-SQLAlchemy is like your favorite matchmaker, setting up SQLAlchemy on a blind date with Flask. It's a custom-tailored suit that makes SQLAlchemy look irresistibly good to Flask, making the integration smoother than a buttered slide.

    Flask-Migrate

    
    

    
    Just like humans occasionally need to reinvent themselves, so do databases. Flask-Migrate is the makeover artist for your database schema, using SQLAlchemy under the hood to keep your database looking fresh and tidy. With it, evolving your database is not a Herculean task but a walk in the park.
    

    from flask_migrate import Migrate
    
    migrate = Migrate(app, db)
