How to create a custom plugin for the Clear Framework? – Universal Structural Steel Construction Blog

Hey there! I’m a supplier for the Clear Framework, and I’ve been getting a bunch of questions lately about creating custom plugins for it. So, I thought I’d put together this blog post to walk you through the process step by step. Whether you’re a seasoned developer or just starting out, I’m gonna make it as easy as pie to understand. Clear Framework

First things first, let’s talk about why you’d even want to create a custom plugin for the Clear Framework. Well, the Clear Framework is a pretty powerful tool on its own, but it’s also super flexible. By creating a custom plugin, you can add new features, integrate with other systems, or just tailor the framework to fit your specific needs. It’s like adding a turbocharger to your car – it makes it go faster and do more cool stuff!

Ok, so now that we’ve got the "why" out of the way, let’s get into the "how". The first thing you need to do is understand the basic structure of the Clear Framework. It’s built on a modular architecture, which means it’s made up of a bunch of smaller components that work together. These components are what you’ll be working with when you create your plugin.

To start creating your plugin, you’ll need to set up a development environment. If you’re using a modern IDE like Visual Studio Code or PyCharm, that’s gonna make your life a whole lot easier. You’ll also need to have a basic understanding of the programming languages used in the Clear Framework. Usually, it’s a mix of Python, JavaScript, and HTML/CSS, so if you’re familiar with those, you’re in good shape.

Once your development environment is set up, it’s time to start coding. The first step is to create a new plugin project. In the Clear Framework, a plugin is usually organized as a directory with a specific structure. You’ll have a main Python file that serves as the entry point for your plugin, and then sub – directories for things like templates, static files (like CSS and JavaScript), and any helper functions.

Let’s say you want to create a plugin that adds a custom dashboard to the Clear Framework. You’d start by creating a new directory for your plugin, let’s call it "custom_dashboard_plugin". Inside that directory, you’ll create a __init__.py file. This is the main file that the Clear Framework will look for when it loads your plugin.

# __init__.py in custom_dashboard_plugin
from clear_framework.plugin import Plugin

class CustomDashboardPlugin(Plugin):
    def __init__(self):
        super().__init__()
        self.name = 'Custom Dashboard Plugin'
        self.version = '1.0'

    def setup(self, app):
        # Here you can add routes, register templates, etc.
        from .routes import register_routes
        register_routes(app)

In the code above, we’ve created a basic plugin class. The setup method is where you’ll do most of the work to integrate your plugin with the Clear Framework. In this example, we’re calling a register_routes function from a routes.py file.

Let’s create that routes.py file.

# routes.py in custom_dashboard_plugin
from flask import Blueprint, render_template

dashboard_bp = Blueprint('dashboard', __name__, template_folder='templates')

def register_routes(app):
    app.register_blueprint(dashboard_bp)

@dashboard_bp.route('/custom-dashboard')
def custom_dashboard():
    return render_template('custom_dashboard.html')

This code creates a Flask blueprint (since the Clear Framework uses Flask under the hood) and registers a route for our custom dashboard. The custom_dashboard.html file should be placed in a templates directory inside our plugin.

<!-- custom_dashboard.html in custom_dashboard_plugin/templates -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF - 8">
    <title>Custom Dashboard</title>
    <!-- You can link CSS here -->
    <link rel="stylesheet" href="{{ url_for('dashboard.static', filename='styles.css') }}">
</head>
<body>
    <h1>Welcome to the Custom Dashboard!</h1>
    <p>This is a custom dashboard created using a plugin for the Clear Framework.</p>
    <!-- You can add JavaScript here -->
    <script src="{{ url_for('dashboard.static', filename='script.js') }}"></script>
</body>
</html>

Alright, so we’ve got the basic structure of our plugin in place. But what if you want to integrate with other systems? Let’s say you want to pull data from an external API. You can use Python libraries like requests to make HTTP requests.

import requests

def get_external_data():
    response = requests.get('https://api.example.com/data')
    if response.status_code == 200:
        return response.json()
    return None

You can then use this data in your templates or in other parts of your plugin.

Testing your plugin is super important. You don’t want to release a plugin that’s full of bugs. You can use testing frameworks like unittest in Python to write unit tests for your plugin. For example, you can test if your routes are working correctly or if the data from the external API is being fetched properly.

import unittest
from your_plugin.routes import custom_dashboard

class TestCustomDashboardPlugin(unittest.TestCase):
    def test_custom_dashboard_route(self):
        result = custom_dashboard()
        self.assertEqual(result.status_code, 200)

Once you’re happy with your plugin and it passes all your tests, it’s time to package it up. You can create a distributable package using tools like setuptools. This will allow you to easily share your plugin with others or deploy it to different environments.

from setuptools import setup, find_packages

setup(
    name='custom_dashboard_plugin',
    version='1.0',
    packages=find_packages(),
    install_requires=[
        # List any dependencies here
        'flask',
        'requests'
    ]
)

To install your plugin in the Clear Framework, you can use pip. Just run pip install /path/to/your/plugin/dist/custom_dashboard_plugin-1.0.tar.gz in your terminal.
