Sending data to a Firefly server via Flask
To send data to an active Firefly webserver you will need to launch Firefly using a method involving Flask.
When Firefly is hosted with a Flask webserver a localhost:xxxx/data_input endpoint is exposed through which new particle data, settings, and tween params can passed to an active Firefly visualization.
Using this endpoint, it is possible to circumvent the need to output
.ffly files entirely, instead creating a Python
string (formatted to contain the
.json data that would’ve been
written to disk as a
.ffly file) that is
POST’d to the data input
endpoint using the
requests Python module.
To facilitate this, we provide the
which will output the data contained in a
Reader instance to a
string and then
POST it to the data input endpoint of
the specified localhost port.
