• Test & Production Configs
• Tests [To Do]

Flask 2.0 async or not async

• asynchronous support in Flask 2.0 is an amazing feature
• however, use it only when it has a clear advantage over the equivalent synchronous code
• write asynchronous code, if your application's routes, etc. are making heavy I/O-bound operations, like:
  • sending emails, making API calls to external servers, working with the file system, etc
• otherwise, if your application is doing CPU-bound operations or long-running tasks, like:
  • processing images or large files, creating backups or running AI/ML models, etc
  • it is advised to use tools like "Celery" or "Huey", etc.

async demo in our application

Check emails/__init__.py to see how emails being sent in async mode

Primary Goals

• To help you save lots of hours as a developer, even if for a hobby project or commercial project :-)
• To provide basic features of standard web apps, while staying as unopinionated as possible
• To make back-end development quick to start, with robust foundations
• To help you quickly learn how to build a Flask based web application
• To help you quick start coding your web app's main logic and features

Getting Started

clone the project

$ git clone https://github.com/ksh7/flask-starter.git
$ cd flask-starter

create virtual environment using python3 and activate it (keep it outside our project directory)

$ python3 -m venv /path/to/your/virtual/environment
$ source <path/to/venv>/bin/activate

install dependencies in virtualenv

$ pip install -r requirements.txt

setup flask command for our app

$ export FLASK_APP=manage.py
$ export FLASK_ENV=development

create instance folder in /tmp directory (sqlite database, temp files stay here)

$ mkdir /tmp/flaskstarter-instance

initialize database and get two default users (admin & demo), check manage.py for details

$ flask initdb

1. start test server at localhost:5000

$ flask run
