Haggle: HTTP Negotiation for humans and machines alike
Helper libraries for automatically making Python services render both an HTML and a machine-readable view for any endpoint.
The idea is to build handler functions that simply return dict-like objects of data and
a negotiate wrapper decides whether to render that dict as JSON or set it as the
context for a template render.
The main use case allows for you to build quick HTML views of data
(reports, dashboards, etc.) that are automatically consumable by other systems with no
additional effort. You merely use the haggle negotiate wrapper instead of a template
decorator you are already using.
Currently only supports aiohttp and jinja2. To install
$ pip install aiohttp-jinja2-haggle
Then to use:
from aiohttp_jinja2_haggle import negotiate
@negotiate('example_template.html')
async def async_handler(_request):
return {'foo': 'bar'}This will return the dict {'foo': 'bar'} as JSON if and only if the request has
the Accept header set to application/json.
If not, this will instead render example_template.html
(via aiohttp_jinja2) with the dict
{'foo': 'bar'} as the template context
