A very micro http framework.
Project description
A very micro HTTP framework.
Features
Very simple, less-code & fast
Using object dispatcher instead of regex route dispatcher.
Url-Encoded & Multipart form parsing.
No request and or response objects is available, everything is combined in nanohttp.context.
You can maryjane to observe the changes in your project directory and reload the development server if desired.
A very flexible configuration system: pymlconf
Roadmap
The road map is to keep it simple with 100% code coverage. no built-in template engine and or ORM will be included.

from nanohttp import quickstart
quickstart(Root())WSGI
Are you need a WSGI application?
app = Root().load_app()
# Pass the ``app`` to every ``WSGI`` server you want.Watch
Create a maryjane.yml file:
port: 8080
module: demo.py
controller: Root
config_file: demo.yml
# Storing the pid of current running server into the `pid` variable.
SHELL-INTO: pid netstat -lnpt 2>/dev/null | grep {port} | awk '{{split($7,a,"/"); printf a[1]}}'
ECHO: Old pid: {pid}
SHELL:
- if [ -n "{pid}" ]; then kill -9 {pid}; fi
- while [ -n "{pid}" -a -e /proc/{pid} ]; do sleep .6; done
- nanohttp -b {port} -c {config_file} {module}:{controller} & echo New pid: $!
WATCH-ALL:
- !^{here}[a-z0-9\.-_/]+\.(css|py|yml|js|html)$$ pip3.6 install "maryjane>=4.2.0"
$ maryjane -wConfig File
Create a demo.yaml file.
debug: falseUse the nanohttp.settings anywhere to access the config values.
from nanohttp import Controller, html, settings
class Root(Controller):
@html
def index(self):
yield '<html><head><title>nanohttp demo</title></head><body>'
yield '<h2>debug flag is: %s</h2>' % settings.debug
yield '</body></html>'Passing the config file(s) using command line:
$ nanohttp -c demo.yaml [-c another.yaml] demoPassing the config file(s) Using python:
from nanohttp import quickstart
quickstart(Root(), config_files=['file1', 'file2'])Command Line Interface
$ nanohttp -h
usage: nanohttp [-h] [-c CONFIG_FILE] [-b {HOST:}PORT] [-d DIRECTORY] [-w]
[-V]
[MODULE{.py}{:CLASS}]
positional arguments:
MODULE{.py}{:CLASS} The python module and controller class to launch.
default: `nanohttp:Demo`, And the default value for
`:CLASS` is `:Root` if omitted.
optional arguments:
-h, --help show this help message and exit
-c CONFIG_FILE, --config-file CONFIG_FILE
Default: nanohttp.yaml
-b {HOST:}PORT, --bind {HOST:}PORT
Bind Address. default: 8080
-d DIRECTORY, --directory DIRECTORY
The path to search for the python module, which
contains the controller class. default is: `.`
-w, --watch If given, tries to watch the `--directory` and reload the app
on changes.
-V, --version Show the version.Release history Release notifications | RSS feed
