# BetterSEQTA+ Plugin System
|
||||
# Creating Plugins for BetterSEQTA+
|
||||
|
||||
BetterSEQTA+ features a powerful plugin system that allows developers to extend and customize the functionality of SEQTA Learn. This document provides an overview of how the plugin system works and how to get started with creating your own plugins.
|
||||
Hey there! 👋 So you want to create a plugin for BetterSEQTA+? That's awesome! This guide will walk you through everything you need to know, from the very basics to more advanced features. Don't worry if you're new to this - we'll explain everything step by step.
|
||||
|
||||
## What is a Plugin?
|
||||
|
||||
A plugin is a self-contained piece of code that adds functionality to BetterSEQTA+. Plugins can:
|
||||
In BetterSEQTA+, a plugin is like a mini-app that adds new features to SEQTA. Think of it as a piece of LEGO that you can snap onto SEQTA to make it do new things. For example, you could create a plugin that:
|
||||
- Changes how SEQTA looks
|
||||
- Adds new buttons or features
|
||||
- Shows extra information on your timetable
|
||||
- Collects notifications in a better way
|
||||
- Really, anything you can imagine!
|
||||
|
||||
- Add new UI elements to SEQTA Learn
|
||||
- Modify existing UI elements
|
||||
- Add new features to SEQTA Learn
|
||||
- Modify or extend existing features
|
||||
- Store and retrieve user data
|
||||
- Respond to events in SEQTA Learn
|
||||
## Your First Plugin
|
||||
|
||||
Each plugin is isolated from other plugins, with its own settings, storage, and lifecycle. This ensures that plugins can be enabled, disabled, or removed without affecting other parts of the system.
|
||||
|
||||
## Plugin Architecture
|
||||
|
||||
The BetterSEQTA+ plugin system consists of several key components:
|
||||
|
||||
### 1. Plugin Interface
|
||||
|
||||
All plugins implement the `Plugin` interface, which defines the structure and lifecycle methods of a plugin:
|
||||
Let's create a super simple plugin together. We'll make one that adds a friendly message to the SEQTA homepage. Here's what we'll need:
|
||||
|
||||
```typescript
|
||||
export interface Plugin<T extends PluginSettings = PluginSettings, S = any> {
|
||||
id: string;
|
||||
name: string;
|
||||
description: string;
|
||||
version: string;
|
||||
settings: T;
|
||||
run: (api: PluginAPI<T, S>) => void | Promise<void> | (() => void) | Promise<(() => void)>;
|
||||
}
|
||||
import type { Plugin } from '@/plugins/core/types';
|
||||
|
||||
const myFirstPlugin: Plugin = {
|
||||
// Every plugin needs these basic details
|
||||
id: 'my-first-plugin',
|
||||
name: 'My First Plugin',
|
||||
description: 'Adds a friendly message to SEQTA',
|
||||
version: '1.0.0',
|
||||
|
||||
// This tells BetterSEQTA+ that users can turn our plugin on/off
|
||||
disableToggle: true,
|
||||
|
||||
// This is where the magic happens!
|
||||
run: async (api) => {
|
||||
// Wait for the homepage to load
|
||||
api.seqta.onMount('.home-page', (homePage) => {
|
||||
// Create our message
|
||||
const message = document.createElement('div');
|
||||
message.textContent = 'Hello from my first plugin! 🎉';
|
||||
message.style.padding = '20px';
|
||||
message.style.backgroundColor = '#e9f5ff';
|
||||
message.style.borderRadius = '8px';
|
||||
message.style.margin = '20px';
|
||||
|
||||
// Add it to the page
|
||||
homePage.prepend(message);
|
||||
});
|
||||
|
||||
// Return a cleanup function that removes our message when the plugin is disabled
|
||||
return () => {
|
||||
const message = document.querySelector('.home-page > div');
|
||||
message?.remove();
|
||||
};
|
||||
}
|
||||
};
|
||||
|
||||
export default myFirstPlugin;
|
||||
```
|
||||
|
||||
### 2. Plugin API
|
||||
Let's break down what's happening here:
|
||||
|
||||
When a plugin is run, it receives an instance of the `PluginAPI`, which provides access to various services and utilities:
|
||||
1. First, we import the `Plugin` type that tells TypeScript what a plugin should look like
|
||||
2. We create our plugin object with some basic information:
|
||||
- `id`: A unique name for your plugin (use lowercase and dashes)
|
||||
- `name`: A friendly name that users will see
|
||||
- `description`: Explain what your plugin does
|
||||
- `version`: Your plugin's version number
|
||||
3. We set `disableToggle: true` so users can turn our plugin on/off in settings
|
||||
4. The `run` function is where we put our plugin's code
|
||||
5. We use `api.seqta.onMount` to wait for the homepage to load
|
||||
6. We create and style a message element
|
||||
7. We return a cleanup function that removes our changes when the plugin is disabled
|
||||
|
||||
## The Plugin API
|
||||
|
||||
When your plugin runs, it gets access to a powerful API that lets you do all sorts of things. Let's look at what you can do:
|
||||
|
||||
### SEQTA API (`api.seqta`)
|
||||
|
||||
This helps you interact with SEQTA's pages:
|
||||
|
||||
```typescript
|
||||
export interface PluginAPI<T extends PluginSettings, S = any> {
|
||||
seqta: SEQTAAPI;
|
||||
settings: SettingsAPI<T>;
|
||||
storage: TypedStorageAPI<S>;
|
||||
events: EventsAPI;
|
||||
}
|
||||
// Wait for an element to appear on the page
|
||||
api.seqta.onMount('.some-class', (element) => {
|
||||
// Do something with the element
|
||||
});
|
||||
|
||||
// Know when the user changes pages
|
||||
api.seqta.onPageChange((page) => {
|
||||
console.log('User went to:', page);
|
||||
});
|
||||
|
||||
// Get the current page
|
||||
const currentPage = api.seqta.getCurrentPage();
|
||||
```
|
||||
|
||||
- **SEQTA API**: Provides methods for interacting with the SEQTA Learn UI
|
||||
- **Settings API**: Provides type-safe access to plugin settings
|
||||
- **Storage API**: Provides type-safe persistent storage for plugin data
|
||||
- **Events API**: Allows plugins to emit and listen for events
|
||||
### Settings API (`api.settings`)
|
||||
|
||||
### 3. Plugin Manager
|
||||
|
||||
The Plugin Manager is responsible for loading, starting, stopping, and managing plugins. It handles the lifecycle of each plugin and ensures that plugins have access to the resources they need.
|
||||
|
||||
### 4. Plugin Registry
|
||||
|
||||
The Plugin Registry is a central repository of all available plugins. Built-in plugins are automatically registered, and additional plugins can be registered dynamically.
|
||||
|
||||
## Plugin Lifecycle
|
||||
|
||||
Plugins follow a simple lifecycle:
|
||||
|
||||
1. **Registration**: The plugin is registered with the Plugin Manager
|
||||
2. **Loading**: The plugin's settings and storage are loaded
|
||||
3. **Running**: The plugin's `run` method is called with the Plugin API
|
||||
4. **Cleanup**: If the plugin returns a cleanup function, it is called when the plugin is stopped
|
||||
|
||||
## Creating a Plugin
|
||||
|
||||
Creating a plugin for BetterSEQTA+ involves a few simple steps:
|
||||
|
||||
1. Define your plugin's interface
|
||||
2. Implement the Plugin interface
|
||||
3. Register your plugin with the Plugin Manager
|
||||
|
||||
For a detailed guide on creating plugins, see [Creating Your First Plugin](./creating-plugins.md).
|
||||
|
||||
## Built-in Plugins
|
||||
|
||||
BetterSEQTA+ comes with several built-in plugins that provide core functionality:
|
||||
|
||||
- **Timetable**: Enhances the SEQTA timetable view
|
||||
- **Notification Collector**: Improves the notification system
|
||||
- **Theme Customizer**: Allows customization of the SEQTA theme
|
||||
- **Assessment Enhancer**: Adds features to the assessment view
|
||||
|
||||
These plugins serve as good examples of how to use the plugin system effectively.
|
||||
|
||||
## Type-Safe Settings and Storage
|
||||
|
||||
One of the key features of the BetterSEQTA+ plugin system is its type-safe settings and storage. Using TypeScript generics, plugins can define the structure of their settings and storage, ensuring that they are used correctly throughout the codebase.
|
||||
|
||||
### Settings Example
|
||||
Want to let users customize your plugin? Use settings!
|
||||
|
||||
```typescript
|
||||
interface MyPluginSettings extends PluginSettings {
|
||||
enabled: {
|
||||
type: 'boolean';
|
||||
default: boolean;
|
||||
title: string;
|
||||
description: string;
|
||||
};
|
||||
refreshInterval: {
|
||||
type: 'number';
|
||||
default: number;
|
||||
title: string;
|
||||
description: string;
|
||||
min: number;
|
||||
max: number;
|
||||
};
|
||||
import { BasePlugin } from '@/plugins/core/settings';
|
||||
import { booleanSetting, defineSettings, Setting } from '@/plugins/core/settingsHelpers';
|
||||
|
||||
// Define your settings
|
||||
const settings = defineSettings({
|
||||
showMessage: booleanSetting({
|
||||
default: true,
|
||||
title: "Show Welcome Message",
|
||||
description: "Show a friendly message on the homepage",
|
||||
})
|
||||
});
|
||||
|
||||
// Create a class for your plugin
|
||||
class MyPluginClass extends BasePlugin<typeof settings> {
|
||||
@Setting(settings.showMessage)
|
||||
showMessage!: boolean;
|
||||
}
|
||||
|
||||
// Create your plugin
|
||||
const settingsInstance = new MyPluginClass();
|
||||
|
||||
const myPlugin: Plugin<typeof settings> = {
|
||||
// ... other plugin details ...
|
||||
settings: settingsInstance.settings,
|
||||
|
||||
run: async (api) => {
|
||||
// Use the setting
|
||||
if (api.settings.showMessage) {
|
||||
// Show the message
|
||||
}
|
||||
|
||||
// Listen for setting changes
|
||||
api.settings.onChange('showMessage', (newValue) => {
|
||||
if (newValue) {
|
||||
// Show the message
|
||||
} else {
|
||||
// Hide the message
|
||||
}
|
||||
});
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### Storage Example
|
||||
### Storage API (`api.storage`)
|
||||
|
||||
Need to save some data? The storage API has got you covered:
|
||||
|
||||
```typescript
|
||||
interface MyPluginStorage {
|
||||
lastRefresh: string;
|
||||
savedItems: string[];
|
||||
userPreferences: {
|
||||
theme: 'light' | 'dark';
|
||||
fontSize: number;
|
||||
};
|
||||
}
|
||||
// Save some data
|
||||
await api.storage.set('lastVisit', new Date().toISOString());
|
||||
|
||||
// Get it back later
|
||||
const lastVisit = await api.storage.get('lastVisit');
|
||||
|
||||
// Listen for changes
|
||||
api.storage.onChange('lastVisit', (newValue) => {
|
||||
console.log('Last visit updated:', newValue);
|
||||
});
|
||||
```
|
||||
|
||||
## Decorator-Based Settings
|
||||
### Events API (`api.events`)
|
||||
|
||||
BetterSEQTA+ also offers a more modern, decorator-based approach to defining settings. For more information, see [Creating Plugins with Settings](../settings/creating-plugins.md).
|
||||
Want your plugin to be able to interface with other plugins? Then use events!
|
||||
|
||||
## Plugin API Reference
|
||||
```typescript
|
||||
// Listen for an event
|
||||
api.events.on('myCustomEvent', (data) => {
|
||||
console.log('Got event:', data);
|
||||
});
|
||||
|
||||
The Plugin API provides a rich set of features for interacting with SEQTA Learn. For a complete reference, see [Plugin API Reference](../advanced/plugin-api.md).
|
||||
// Send an event
|
||||
api.events.emit('myCustomEvent', { some: 'data' });
|
||||
```
|
||||
|
||||
## Adding Styles
|
||||
|
||||
Want to make your plugin look pretty? You can add CSS styles:
|
||||
|
||||
```typescript
|
||||
const myPlugin: Plugin = {
|
||||
// ... other plugin details ...
|
||||
|
||||
// Add your CSS here
|
||||
styles: `
|
||||
.my-plugin-message {
|
||||
background: linear-gradient(135deg, #6e8efb, #a777e3);
|
||||
color: white;
|
||||
padding: 20px;
|
||||
border-radius: 12px;
|
||||
box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
|
||||
margin: 20px;
|
||||
animation: slide-in 0.3s ease-out;
|
||||
}
|
||||
|
||||
@keyframes slide-in {
|
||||
from { transform: translateY(-20px); opacity: 0; }
|
||||
to { transform: translateY(0); opacity: 1; }
|
||||
}
|
||||
`,
|
||||
|
||||
run: async (api) => {
|
||||
// Your plugin code here
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
When creating plugins for BetterSEQTA+, consider these best practices:
|
||||
Here are some tips to make your plugin awesome:
|
||||
|
||||
1. **Use TypeScript**: Take advantage of TypeScript's type system to ensure type safety in your plugins.
|
||||
2. **Keep Plugins Focused**: Each plugin should do one thing well.
|
||||
3. **Handle Cleanup**: Always return a cleanup function from your plugin's `run` method to ensure proper resource management.
|
||||
4. **Document Your Code**: Add clear documentation to your code, especially for public APIs.
|
||||
5. **Test Thoroughly**: Test your plugins in different environments and with different configurations.
|
||||
6. **Follow UI Guidelines**: When adding UI elements, follow the SEQTA Learn UI guidelines to maintain a consistent experience.
|
||||
7. **Optimize Performance**: Be mindful of performance impact, especially for plugins that run on every page.
|
||||
1. **Always Clean Up**: When your plugin is disabled, clean up any changes you made:
|
||||
```typescript
|
||||
run: async (api) => {
|
||||
// Add stuff to the page
|
||||
const element = document.createElement('div');
|
||||
document.body.appendChild(element);
|
||||
|
||||
// Return a cleanup function
|
||||
return () => {
|
||||
element.remove();
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
2. **Use TypeScript**: It helps catch errors before they happen and makes your code easier to understand.
|
||||
|
||||
- [Creating Your First Plugin](./creating-plugins.md)
|
||||
- [Plugin API Reference](../advanced/plugin-api.md)
|
||||
- [Typed Storage API](../advanced/storage-api.md)
|
||||
3. **Test Your Plugin**: Make sure it works in different situations:
|
||||
- When SEQTA is loading
|
||||
- When the user switches pages
|
||||
- When the plugin is enabled/disabled
|
||||
- When settings are changed
|
||||
|
||||
4. **Keep It Fast**: Don't slow down SEQTA:
|
||||
- Use `onMount` instead of intervals or timeouts
|
||||
- Clean up event listeners when they're not needed
|
||||
- Don't do heavy calculations on the main thread
|
||||
|
||||
5. **Make It User-Friendly**:
|
||||
- Add clear settings with good descriptions
|
||||
- Use `disableToggle: true` so users can turn it off if needed
|
||||
- Add helpful error messages if something goes wrong
|
||||
|
||||

# Plugin API Reference
|
||||
|
||||
This document provides detailed technical information about BetterSEQTA+'s plugin APIs. For a beginner-friendly introduction, see [Creating Your First Plugin](./README.md).
|
||||
|
||||
## Plugin Interface
|
||||
|
||||
The core `Plugin` interface that all plugins must implement:
|
||||
|
||||
```typescript
|
||||
interface Plugin<T extends PluginSettings = PluginSettings, S = any> {
|
||||
id: string; // Unique identifier for the plugin
|
||||
name: string; // Display name
|
||||
description: string; // Plugin description
|
||||
version: string; // Semantic version (e.g. "1.0.0")
|
||||
settings: T; // Plugin settings (type-safe)
|
||||
styles?: string; // Optional CSS styles
|
||||
disableToggle?: boolean; // Whether to show enable/disable toggle
|
||||
run: (api: PluginAPI<T, S>) => void | Promise<void> | (() => void) | Promise<(() => void)>;
|
||||
}
|
||||
```
|
||||
|
||||
## SEQTA API
|
||||
|
||||
The `SEQTAAPI` interface provides methods for interacting with SEQTA's UI:
|
||||
|
||||
```typescript
|
||||
interface SEQTAAPI {
|
||||
// Wait for an element to appear in the DOM
|
||||
onMount(
|
||||
selector: string, // CSS selector
|
||||
callback: (el: Element) => void
|
||||
): { unregister: () => void };
|
||||
|
||||
// Get React fiber for debugging/advanced usage
|
||||
getFiber(selector: string): ReactFiber;
|
||||
|
||||
// Get current SEQTA page
|
||||
getCurrentPage(): string;
|
||||
|
||||
// Listen for page changes
|
||||
onPageChange(
|
||||
callback: (page: string) => void
|
||||
): { unregister: () => void };
|
||||
}
|
||||
```
|
||||
|
||||
## Settings API
|
||||
|
||||
The settings system provides type-safe plugin configuration:
|
||||
|
||||
```typescript
|
||||
interface SettingsAPI<T extends PluginSettings> {
|
||||
// Access setting values
|
||||
[K in keyof T]: SettingValue<T[K]>;
|
||||
|
||||
// Listen for setting changes
|
||||
onChange<K extends keyof T>(
|
||||
key: K,
|
||||
callback: (value: SettingValue<T[K]>) => void
|
||||
): { unregister: () => void };
|
||||
|
||||
// Remove change listener
|
||||
offChange<K extends keyof T>(
|
||||
key: K,
|
||||
callback: (value: SettingValue<T[K]>) => void
|
||||
): void;
|
||||
|
||||
// Promise that resolves when settings are loaded
|
||||
loaded: Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
### Setting Types
|
||||
|
||||
Available setting types:
|
||||
|
||||
```typescript
|
||||
// Boolean toggle
|
||||
booleanSetting({
|
||||
default: boolean;
|
||||
title: string;
|
||||
description: string;
|
||||
});
|
||||
|
||||
// Text input
|
||||
stringSetting({
|
||||
default: string;
|
||||
title: string;
|
||||
description: string;
|
||||
placeholder?: string;
|
||||
});
|
||||
|
||||
// Number input
|
||||
numberSetting({
|
||||
default: number;
|
||||
title: string;
|
||||
description: string;
|
||||
min?: number;
|
||||
max?: number;
|
||||
step?: number;
|
||||
});
|
||||
|
||||
// Dropdown select
|
||||
selectSetting<T extends string>({
|
||||
default: T;
|
||||
title: string;
|
||||
description: string;
|
||||
options: Array<{
|
||||
value: T;
|
||||
label: string;
|
||||
}>;
|
||||
});
|
||||
```
|
||||
|
||||
### Using Settings
|
||||
|
||||
Two ways to define settings:
|
||||
|
||||
1. Using the BasePlugin class (recommended):
|
||||
```typescript
|
||||
const settings = defineSettings({
|
||||
mySetting: booleanSetting({...})
|
||||
});
|
||||
|
||||
class MyPlugin extends BasePlugin<typeof settings> {
|
||||
@Setting(settings.mySetting)
|
||||
mySetting!: boolean;
|
||||
}
|
||||
```
|
||||
|
||||
2. Direct object (simpler but less type-safe):
|
||||
```typescript
|
||||
const settings = {
|
||||
mySetting: booleanSetting({...})
|
||||
};
|
||||
```
|
||||
|
||||
## Storage API
|
||||
|
||||
Persistent storage for plugin data:
|
||||
|
||||
```typescript
|
||||
interface StorageAPI<T = any> {
|
||||
// Get a stored value
|
||||
get<K extends keyof T>(key: K): Promise<T[K] | undefined>;
|
||||
|
||||
// Set a value
|
||||
set<K extends keyof T>(key: K, value: T[K]): Promise<void>;
|
||||
|
||||
// Delete a value
|
||||
delete<K extends keyof T>(key: K): Promise<void>;
|
||||
|
||||
// Listen for changes
|
||||
onChange<K extends keyof T>(
|
||||
key: K,
|
||||
callback: (value: T[K]) => void
|
||||
): { unregister: () => void };
|
||||
|
||||
// Promise that resolves when storage is loaded
|
||||
loaded: Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
Storage is:
|
||||
- Persistent across page reloads
|
||||
- Isolated per plugin (plugins can't access each other's storage)
|
||||
- Type-safe when using TypeScript
|
||||
- Automatically synchronized across tabs
|
||||
|
||||
## Events API
|
||||
|
||||
Inter-plugin communication system:
|
||||
|
||||
```typescript
|
||||
interface EventsAPI {
|
||||
// Listen for an event
|
||||
on(
|
||||
event: string,
|
||||
callback: (...args: any[]) => void
|
||||
): { unregister: () => void };
|
||||
|
||||
// Emit an event
|
||||
emit(event: string, ...args: any[]): void;
|
||||
}
|
||||
```
|
||||
|
||||
Event naming conventions:
|
||||
- Use `plugin.{pluginId}.{eventName}` for plugin-specific events
|
||||
- Use `seqta.{eventName}` for SEQTA-related events
|
||||
- Use `global.{eventName}` for system-wide events
|
||||
|
||||
## Plugin Lifecycle
|
||||
|
||||
1. **Registration**:
|
||||
```typescript
|
||||
PluginManager.getInstance().registerPlugin(myPlugin);
|
||||
```
|
||||
|
||||
2. **Initialization**:
|
||||
- Plugin's `run` function is called
|
||||
- Settings and storage are loaded
|
||||
- CSS styles are injected (if any)
|
||||
|
||||
3. **Running**:
|
||||
- Plugin can use all APIs
|
||||
- Can listen for events and changes
|
||||
- Can modify SEQTA's UI
|
||||
|
||||
4. **Cleanup**:
|
||||
- When plugin is disabled or unloaded
|
||||
- Cleanup function from `run` is called
|
||||
- CSS styles are removed
|
||||
- Event listeners are cleaned up
|
||||
|
||||
## Type Safety
|
||||
|
||||
TypeScript types for type-safe plugins:
|
||||
|
||||
```typescript
|
||||
// Plugin with settings and storage types
|
||||
interface MyPluginSettings {
|
||||
theme: string;
|
||||
notifications: boolean;
|
||||
}
|
||||
|
||||
interface MyPluginStorage {
|
||||
lastVisit: string;
|
||||
userData: { name: string; id: number };
|
||||
}
|
||||
|
||||
const myPlugin: Plugin<MyPluginSettings, MyPluginStorage> = {
|
||||
// TypeScript will ensure type safety for:
|
||||
// - Settings access and changes
|
||||
// - Storage operations
|
||||
// - Event payloads (when typed)
|
||||
};
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
Best practices for plugin error handling:
|
||||
|
||||
```typescript
|
||||
run: async (api) => {
|
||||
try {
|
||||
// Initialization
|
||||
await someAsyncOperation();
|
||||
|
||||
// Return cleanup
|
||||
return () => {
|
||||
try {
|
||||
// Cleanup code
|
||||
} catch (error) {
|
||||
console.error('Plugin cleanup failed:', error);
|
||||
}
|
||||
};
|
||||
} catch (error) {
|
||||
// Log error but don't crash
|
||||
console.error('Plugin initialization failed:', error);
|
||||
|
||||
// Still return cleanup to ensure proper shutdown
|
||||
return () => {};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
1. **DOM Operations**:
|
||||
- Use `onMount` instead of polling
|
||||
- Batch DOM updates
|
||||
- Use CSS classes instead of inline styles
|
||||
- Remove listeners when not needed
|
||||
|
||||
2. **Storage**:
|
||||
- Cache frequently accessed values
|
||||
- Batch storage operations
|
||||
- Don't store large objects
|
||||
|
||||
3. **Events**:
|
||||
- Clean up listeners
|
||||
- Use typed events
|
||||
- Don't emit events too frequently
|
||||
|
||||
4. **Settings**:
|
||||
- Use appropriate setting types
|
||||
- Provide good defaults
|
||||
- Handle setting changes efficiently

# Creating Your First Plugin
|
||||
|
||||
This guide will walk you through the process of creating a plugin for BetterSEQTA+, from setup to implementation to testing.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before you start creating a plugin, make sure you have:
|
||||
|
||||
- Basic knowledge of TypeScript
|
||||
- Familiarity with the BetterSEQTA+ codebase
|
||||
- A development environment set up according to the [Installation Guide](../installation.md)
|
||||
|
||||
## Plugin Structure
|
||||
|
||||
A typical BetterSEQTA+ plugin consists of:
|
||||
|
||||
1. **Plugin Definition**: A TypeScript file that defines the plugin's metadata and functionality
|
||||
2. **Settings Interface**: (Optional) A TypeScript interface that defines the plugin's settings
|
||||
3. **Storage Interface**: (Optional) A TypeScript interface that defines the plugin's storage structure
|
||||
|
||||
## Step 1: Planning Your Plugin
|
||||
|
||||
Before you start coding, take some time to plan your plugin:
|
||||
|
||||
1. **Identify the Problem**: What issue or need does your plugin address?
|
||||
2. **Define the Scope**: What specific features will your plugin include?
|
||||
3. **Consider the User Experience**: How will users interact with your plugin?
|
||||
|
||||
## Step 2: Creating the Plugin File
|
||||
|
||||
Create a new TypeScript file for your plugin. The convention is to place it in the `src/plugins/` directory, either in the `built-in` folder or a new folder if it's a third-party plugin.
|
||||
|
||||
```typescript
|
||||
// src/plugins/my-plugin/index.ts
|
||||
|
||||
import { Plugin, PluginAPI, PluginSettings } from '../../core/types';
|
||||
|
||||
export interface MyPluginSettings extends PluginSettings {
|
||||
enabled: {
|
||||
type: 'boolean';
|
||||
default: true;
|
||||
title: 'Enable My Plugin';
|
||||
description: 'Turn my plugin on or off';
|
||||
};
|
||||
// Add more settings as needed
|
||||
}
|
||||
|
||||
export interface MyPluginStorage {
|
||||
lastRun: string;
|
||||
// Add more storage fields as needed
|
||||
}
|
||||
|
||||
const myPlugin: Plugin<MyPluginSettings, MyPluginStorage> = {
|
||||
id: 'my-plugin',
|
||||
name: 'My Plugin',
|
||||
description: 'A simple plugin for BetterSEQTA+',
|
||||
version: '1.0.0',
|
||||
settings: {
|
||||
enabled: {
|
||||
type: 'boolean',
|
||||
default: true,
|
||||
title: 'Enable My Plugin',
|
||||
description: 'Turn my plugin on or off',
|
||||
},
|
||||
// Initialize your settings here
|
||||
},
|
||||
run: (api) => {
|
||||
if (!api.settings.enabled) {
|
||||
return;
|
||||
}
|
||||
|
||||
// Initialize storage with default values if needed
|
||||
if (api.storage.lastRun === undefined) {
|
||||
api.storage.lastRun = new Date().toISOString();
|
||||
}
|
||||
|
||||
// Your plugin logic goes here
|
||||
console.log('My Plugin is running!');
|
||||
|
||||
// Access the SEQTA API
|
||||
api.seqta.onPageLoad('/timetable', () => {
|
||||
// Code to run when the timetable page loads
|
||||
});
|
||||
|
||||
// Return a cleanup function (optional but recommended)
|
||||
return () => {
|
||||
console.log('My Plugin is cleaning up!');
|
||||
// Cleanup logic goes here
|
||||
};
|
||||
},
|
||||
};
|
||||
|
||||
export default myPlugin;
|
||||
```
|
||||
|
||||
## Step 3: Registering Your Plugin
|
||||
|
||||
To make your plugin available to BetterSEQTA+, you need to register it with the Plugin Manager. For built-in plugins, you can add your plugin to the `src/plugins/built-in/index.ts` file:
|
||||
|
||||
```typescript
|
||||
// src/plugins/built-in/index.ts
|
||||
|
||||
import myPlugin from './my-plugin';
|
||||
// Other imports...
|
||||
|
||||
export const builtInPlugins = [
|
||||
myPlugin,
|
||||
// Other plugins...
|
||||
];
|
||||
```
|
||||
|
||||
For third-party plugins, you'll need to follow a different approach, as detailed in [Third-Party Plugins](../advanced/third-party-plugins.md).
|
||||
|
||||
## Step 4: Implementing Your Plugin Logic
|
||||
|
||||
The main functionality of your plugin goes in the `run` method. Here are some common patterns:
|
||||
|
||||
### Responding to Page Loads
|
||||
|
||||
```typescript
|
||||
api.seqta.onPageLoad('/timetable', () => {
|
||||
// Code to run when the timetable page loads
|
||||
});
|
||||
```
|
||||
|
||||
### Modifying the UI
|
||||
|
||||
```typescript
|
||||
api.seqta.onPageLoad('/timetable', () => {
|
||||
const timetableElement = document.querySelector('.timetable');
|
||||
if (timetableElement) {
|
||||
// Modify the timetable element
|
||||
const controlsDiv = document.createElement('div');
|
||||
controlsDiv.className = 'my-plugin-controls';
|
||||
controlsDiv.innerHTML = '<button>Zoom In</button><button>Zoom Out</button>';
|
||||
timetableElement.appendChild(controlsDiv);
|
||||
|
||||
// Add event listeners
|
||||
controlsDiv.querySelector('button:first-child').addEventListener('click', () => {
|
||||
// Zoom in logic
|
||||
});
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Working with Settings
|
||||
|
||||
```typescript
|
||||
// Get a setting value
|
||||
const isEnabled = api.settings.enabled;
|
||||
|
||||
// Listen for settings changes
|
||||
api.settings.onChange('enabled', (newValue) => {
|
||||
if (newValue) {
|
||||
// Enable functionality
|
||||
} else {
|
||||
// Disable functionality
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Working with Storage
|
||||
|
||||
```typescript
|
||||
// Get a stored value
|
||||
const lastRun = api.storage.lastRun;
|
||||
|
||||
// Set a stored value
|
||||
api.storage.lastRun = new Date().toISOString();
|
||||
|
||||
// Listen for storage changes
|
||||
api.storage.onChange('lastRun', (newValue) => {
|
||||
console.log(`Last run updated to: ${newValue}`);
|
||||
});
|
||||
```
|
||||
|
||||
### Working with Events
|
||||
|
||||
```typescript
|
||||
// Listen for events
|
||||
api.events.on('assessmentLoaded', (data) => {
|
||||
console.log(`Assessment loaded: ${data.id}`);
|
||||
});
|
||||
|
||||
// Emit an event
|
||||
api.events.emit('myPluginEvent', { message: 'Hello from My Plugin!' });
|
||||
```
|
||||
|
||||
## Step 5: Testing Your Plugin
|
||||
|
||||
To test your plugin:
|
||||
|
||||
1. Run the development server:
|
||||
```
|
||||
npm run dev
|
||||
```
|
||||
|
||||
2. Open SEQTA Learn in your browser with BetterSEQTA+ enabled.
|
||||
|
||||
3. Check the console for any error messages.
|
||||
|
||||
4. Verify that your plugin works as expected.
|
||||
|
||||
## Step 6: Adding Plugin Settings UI
|
||||
|
||||
If your plugin has settings, they will automatically appear in the BetterSEQTA+ settings panel. The UI is generated based on the settings interface you defined.
|
||||
|
||||
For more control over the settings UI, you can use the decorator-based settings system. See [Creating Plugins with Settings](../settings/creating-plugins.md) for more information.
|
||||
|
||||
## Best Practices for Plugin Development
|
||||
|
||||
1. **Follow TypeScript Best Practices**: Use proper typing for all variables and functions.
|
||||
|
||||
2. **Handle Errors Gracefully**: Wrap your code in try-catch blocks to prevent crashes.
|
||||
```typescript
|
||||
try {
|
||||
// Your code
|
||||
} catch (error) {
|
||||
console.error('My Plugin Error:', error);
|
||||
}
|
||||
```
|
||||
|
||||
3. **Clean Up After Yourself**: Always return a cleanup function from your plugin's `run` method.
|
||||
```typescript
|
||||
const cleanup = () => {
|
||||
// Remove event listeners, DOM elements, etc.
|
||||
};
|
||||
return cleanup;
|
||||
```
|
||||
|
||||
4. **Document Your Code**: Add comments to explain complex logic or unusual patterns.
|
||||
|
||||
5. **Keep It Simple**: Start with a simple plugin and add features incrementally.
|
||||
|
||||
## Example Plugins
|
||||
|
||||
For inspiration, check out these example plugins in the BetterSEQTA+ codebase:
|
||||
|
||||
1. **Timetable Plugin**: Enhances the SEQTA timetable view with zoom controls and filtering options.
|
||||
- Location: `src/plugins/built-in/timetable/index.ts`
|
||||
|
||||
2. **Notification Collector**: Improves the notification system in SEQTA Learn.
|
||||
- Location: `src/plugins/built-in/notification-collector/index.ts`
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Plugin Not Loading
|
||||
|
||||
- Check that your plugin is properly registered
|
||||
- Verify that there are no TypeScript errors
|
||||
- Look for error messages in the console
|
||||
|
||||
### Plugin Not Working as Expected
|
||||
|
||||
- Ensure that your plugin's `enabled` setting is true
|
||||
- Check that your selectors match the SEQTA DOM structure
|
||||
- Use `console.log` statements to debug your code
|
||||
|
||||
### TypeScript Errors
|
||||
|
||||
- Make sure your interfaces are properly defined
|
||||
- Check that you're using the correct types for the plugin API
|
||||
- Verify that your plugin implements the `Plugin` interface correctly
