Overview

Primrose is a Ruby library designed for building component-based web applications. It provides a collection of modules and classes to manage the state, routing, rendering, and event handling for a modern web application. Primrose offers the following key features:

• State Management using Primrose::Store
• Component-based UI building blocks via Primrose::Rose subclasses
• Routing capabilities with Primrose::Router
• Observable state via Primrose::Observable
• Built-in helper methods and utility functions
• Template-based rendering with ERB

Usage

State Management

store = Primrose::Store.new({ counter: 0 })

store.dispatch({
  type: 'INCREMENT',
  updates: {
    counter: -> (current_value) { current_value + 1 }
  }
})

Routing

router = Primrose::Router.new

router.route('/home') { puts "You're at home" }
router.route('/about') { puts "About page" }

router.navigate('/home')  # Outputs "You're at home"

Components

Creating a custom component is easy:

class MyComponent < Primrose::Rose
  def render
    "Hello, world!"
  end
end

Event Handling

You can attach event handlers to your components:

component = MyComponent.new
component.on(:click) { puts 'Component clicked!' }
component.trigger(:click)  # Outputs "Component clicked!"

---

Examples

Below are some example templates to showcase how components can be structured.

• Button Component:

  <button onclick="<%= @action %>">
    <%= @label %>
  </button>

• Text Field Component:

  <input type="text" placeholder="<%= @placeholder %>">

• Checkbox Component:

  <div class="checkbox">
    <input type="checkbox">
    <label><%= @label %></label>
  </div>
