falcon-api-browse's Introduction

Falcon API Browse

This project provides a middleware for Falcon Web Framework that will render the response in an HTML form for documentation purpose. It uses the docstring from the Resource object and all the supported HTTP methods for the resource.

It is inspired by Django Rest Framework's Browsable API and is written using jinja2 templating language.

Installing

This project is currently in early stages of development. Once it is stable enough to be used by other projects, it will be provided via PyPI.

pip install falcon-api-browse

Using

Since this is a middleware for Falcon, you can use it by passing an initialized instance during Falcon App creation.

from falcon import App
from falcon_api_browse import HTMLResponseMiddleware

app = App(middleware=HTMLResponseMiddleware())

Examples

There are some runnable examples in examples/ directory.

falcon-api-browse's Issues

No module named `importlib_resources`

It seems that some dependencies are required, but not listed:

  File "/tmp/test.py", line 2, in <module>
    from falcon_api_browse import HTMLResponseMiddleware
  File "/tmp/venv/lib/python3.8/site-packages/falcon_api_browse/__init__.py", line 1, in <module>
    from falcon_api_browse.middleware import HTMLResponseMiddleware
  File "/tmp/venv/lib/python3.8/site-packages/falcon_api_browse/middleware.py", line 1, in <module>
    from falcon_api_browse.views import html_response
  File "/tmp/venv/lib/python3.8/site-packages/falcon_api_browse/views.py", line 4, in <module>
    from importlib_resources import files
ModuleNotFoundError: No module named 'importlib_resources'

Guard against malformed json

It is possible for the response to be malformed json or something, make sure that we guard against json.JSONDecodeError.

Update README.md for ASGI support

See #10 and #6

Add basic sanity tests

We need to add some sanity testing to make sure that we are atleast able to avoid simple errors.

Add support for forcing json response with format query parameter.

Like DRF, add a http://url?format=json query parameter that returns the json encoded response instead of the HTML page.

Add some CSS to the default template

The current default template is very vanilla, it could use some styling support with CSS. We could also urlize some of the urls, although it doesn't seem to work with the default urlize function for whatever reason (probably, because URLs are strings with "<url>" enclosing quotes that throws off their regex matcher.

Add runnable examples

Add atleast two basic examples for ASGI and WSGI respectively that can be run easily.

JSON from `resp.media` is not recognized

It seems this only works as expected if JSON is rendered via resp.text; however, the most idiomatic and succinct way of writing a JSON API is by leveraging req.get_media() and resp.media.

Test case used:

import falcon
from falcon_api_browse import HTMLResponseMiddleware


class Hello:
    def on_get(self, req, resp):
        resp.media = {'message': 'Hello, World!', 'cool': True}


app = falcon.App(middleware=[HTMLResponseMiddleware()])
app.add_route('/hello', Hello())

ASGI support

Since HTMLResponseMiddleware doesn't seem to perform any taxing I/O, one could implement ASGI support by simply wrapping the current logic via async def process_response_async(...).

Verify the response's content_type before assuming it is JSON

We currently assume that the response is JSON, but it can be anything like HTML, msgpack etc. We should not make this assumption and add some guard to verify the response's content_type.
