The python middleware for neuron.js
Project description
neuronjs
Python utilities and middleware for neuron.js
neuronjs analyzes the dependencies from user defined facades according to the dependency tree, and outputs <script> tags and configurations for neuron.js
The dependency tree can be generated by neuron-package-dependency
Install
$ pip install neuronjs
Usage
from neuronjs import Neuron
n = Neuron(
dependency_tree=dependency_tree, # must defined
resolve=resolve,
version=version,
cache=cache,
debug=False)
neuronjs could be used either in template file or your python controller.
Here is a sample Jinja2 template file.
dependency_tree dict the json.loads()ed dependency tree
resolve function(id)= (optional) implements your own custom resolver. resolve accepts one parameter id which can be either a str of module id or a list of module ids. If a str is passed in, the method should returns the resolved absolute url of the module id. If id is a list, an url of comboed script files should be returned.
debug function|bool=False tells neuronjs whether should switch on debug mode. When on debug mode, no javascript files of dependencies will be preloaded, and the output will not be compressed.
if debug is callable, neuronjs will use the return value of method debug
if debug is a boolean value, and debug is true, the debug mode will be on.
cache dict=None if cache is defined, it should contains 3 methods:
cache.has(key) returns bool
cache.get(key) looks up and returns the cached value by key
cache.set(key, value) sets the value by key
version str only works if cache is defined. neuronjs will uses version to generate the key to cache the output result
module id
<name>@<version><path> # for example: 'jquery@2.0.0/jquery.js'
n.facade(entry, data=None)
entry str id of the entry module
Registers a facade entry with data. neuronjs will
Returns ''(empty string), so you can use this method in python template
n.combo(id…)
Returns ''
n.css(id)
Returns ''
n.output()
Returns str
n.output_css()
Returns str
