Offline

The offline mode provides a simple, browser-based approach to storing user consent decisions without requiring a backend server.

Key Characteristics

• No backend required - Everything is stored locally in the browser
• Simplified setup - Get started quickly with minimal configuration
• Independence - Works without external services or APIs
• Fast implementation - Ideal for prototyping and simpler sites

Implementation

import { configureConsentManager, type ConsentManagerOptions } from 'c15t';

export const c15tConfig: ConsentManagerOptions = {
  mode: 'offline',
  consentCategories: ['necessary', 'marketing'], // Optional: Specify which consent categories to show in the banner. 
};

const c15t = configureConsentManager(c15tConfig);

How It Works

The offline mode implements the same interface as the standard client, but with the following differences:

1. Storage: All consent preferences are stored in the browser's localStorage using the configured key
2. Network: No network requests are made, all operations happen locally
3. Consent Banner: The banner visibility is determined by checking if a value exists in localStorage
4. Consent Verification: Always returns a successful response
