alpinejs/alpine: A rugged, minimal framework for composing JavaScript behavior in your markup.

Alpine.js is a great JS framework to have in your toolbox when you don't need a big framework like Vue or React yet shares a similar syntax with Vue. The best part is that you can start using it by linking to a CDN version without having to configure or compile anything.

Alpine.js

npm bundle size npm version Chat

Alpine.js offers you the reactive and declarative nature of big frameworks like Vue or React at a much lower cost.

You get to keep your DOM, and sprinkle in behavior as you see fit.

Think of it like Tailwind for JavaScript.

Note: This tool's syntax is almost entirely borrowed from Vue (and by extension Angular). I am forever grateful for the gift they are to the web.

Install

From CDN: Add the following script to the end of your <head> section.

<script src="https://cdn.jsdelivr.net/gh/alpinejs/alpine@v2.x.x/dist/alpine.min.js" defer></script>

That's it. It will initialize itself.

For production environments, it's recommended to pin a specific version number in the link to avoid unexpected breakage from newer versions For example, to use version 2.6.0 (latest):

🍯 Generic honeypot utilities for use in django projects.

django-honeypot

https://travis-ci.com/jamesturk/django-honeypot.svg?branch=master

Django application that provides utilities for preventing automated form spam.

Provides template tags, view decorators, and middleware to add and verify honeypot fields to forms.

Written by James Turk with contributions by Flavio Curella and Daniel Greenfeld.

Source: http://github.com/jamesturk/django-honeypot/

Requirements

  • python >= 3.6
  • django >= 2.2

(django-honeypot 0.7 supports Django 1.11 and Python 2.7)

Usage

settings.py

Be sure to add honeypot to INSTALLED_APPS in settings.py.

You will almost always need to define HONEYPOT_FIELD_NAME which is the name to use for the honeypot field. Some sophisticated bots will attempt to avoid fields named honeypot, so it may be wise to name the field something slightly more realistic such as "phonenumber" or "body2". (Note: be sure not to name the field anything that will conflict with other forms on your page, "name" is a good example of a field that will likely cause issues.)

HONEYPOT_VALUE is an option that you can…
