Insanic

Insanic is a microservice framework that extends sanic. It tries to include all the best practices for developing in a microservice architecture. To do this, certain stacks were needed, as a result Insanic is a pretty opinionated framework.

Think of this as django-rest-framework is to django but for microservice usage (and a lot less functionality than drf).

Why we needed this

We needed this because we need a framework for our developers to quickly develop services while migrating to a microservice architecture.

As stated before, this is very opinionated and the reason being, to reduce research time when trying to select packages to use for their service. It lays down all the necessary patterns and bootstraps the application for quick cycle time between idea and deployment.

FEATURES

• Authentication and Authorization for Users and other Services (like drf)
• Easy Service Requests
• Normalized Error Message Formats
• Connection manager to redis
• Utils for extracting public routes (will help when registering to api gateway)
• Bootstrap monitoring endpoints
• Throttling

Installation

Prerequisites

Core dependencies include:

• sanic - extends sanic
• httpx - to make async requests to other services
• PyJWT - for authentication
• Redis - for cache and throttling

To install:

$ pip install insanic-framework

Usage

For very basic usage, it is pretty much the same as Sanic:

1. Create a python file. ex. app.py

from insanic import Insanic
from insanic.conf import settings
from sanic.response import json

settings.configure()
__version__ = "0.1.0"

app = Insanic(__name__, version=__version__)

@app.route('/')
async def example(request):
    return json({"insanic": "Gotta go insanely fast!"})

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)

2. Run with

python run.py

3. Check in browser or curl

curl http://localhost:8000/

For more examples and usage, please refer to the documentation.

Testing

Insanic tests are run with pytest and tox.

$ pytest

# with coverage
$ pytest --cov=insanic --cov-report term-missing:skip-covered

# a certain set of tests
$ pytest --pytest-args tests/test_pact.py

# tox, run for sanic > 19.12 and python >= 3.6
$ tox
