Flask-Utils

A collection of useful Flask utilities I use every day in my Flask projects.

Installation

pip install flask-utils

Usage

from flask import Flask
from flask_utils import FlaskUtils
from flask_utils import BadRequestError

app = Flask(__name__)
utils = FlaskUtils(app, register_error_handlers=True)

@app.route('/')
def index():
    raise BadRequestError

from typing import List, Optional
from flask import Flask
from flask_utils import validate_params

app = Flask(__name__)

@app.post('/create-user')
@validate_params({"first_name": str, "last_name": str, "age": Optional[int], "hobbies": List[str]})
def create_user():
    # ...
    # This will enforce the following rules:
    # - first_name and last_name must be strings and are required
    # - age is optional and must be an integer
    # - hobbies is a list of strings
    # This is just an example, you can use any type of validation you want
    return "User created"
