StaticDelivr

StaticDelivr is a lightweight React library for optimizing image delivery by leveraging StaticDelivr's CDN. It simplifies image optimization with support for resizing, quality adjustments, and format conversions, ensuring your application delivers the best possible image performance.

Features

• Seamless integration with React.
• Dynamic resizing and quality optimization of images.
• Automatic format conversion to modern formats like WebP and AVIF.
• Easy configuration with customizable base URL.
• Support for both absolute and relative image paths.

Installation

Install the package via npm:

npm install staticdelivr

Or using yarn:

yarn add staticdelivr

Usage

Basic Usage

import React from 'react';
import { StaticDelivrImage, StaticDelivr } from 'staticdelivr';

// Configure the base URL for relative image paths
StaticDelivr.set({ baseURL: 'https://example.com/images/' });

const App = () => (
  <div>
    <StaticDelivrImage
      src="local/image.png"
      width={800}
      height={600}
      quality={80}
      format="webp"
      alt="Optimized Image"
    />
  </div>
);

export default App;

Props

Configuring the Base URL

The base URL is used for resolving relative image paths and is configured globally. This means once you set it using StaticDelivr.set(), it will apply across your entire application unless changed.

StaticDelivr.set({ baseURL: 'https://example.com/images/' });

This configuration is especially useful when working with relative URLs. If a relative path is provided in the src prop, it will be automatically resolved using the global baseURL. If you pass an absolute URL to the src prop, the base URL will not be applied.

Example: Configuring in a Global Application File

You can configure the base URL globally in a file like _app.tsx in a Next.js application:

// pages/_app.tsx
import React from 'react';
import { StaticDelivr } from 'staticdelivr';

StaticDelivr.set({ baseURL: 'https://example.com/images/' });

const MyApp = ({ Component, pageProps }) => <Component {...pageProps} />;

export default MyApp;

Example: Absolute URLs

<StaticDelivrImage
  src="https://other-cdn.com/image.jpg"
  width={400}
  height={300}
  quality={90}
  format="jpeg"
  alt="External Image"
/>

Example: Relative URLs

<StaticDelivrImage
  src="/path/to/image.jpg"
  width={500}
  height={400}
  quality={70}
  format="png"
  alt="Local Image"
/>

Easy Integration

StaticDelivr is designed to be straightforward to integrate into your application. You can directly replace your existing <img> tags or components like the Next.js <Image> tag with StaticDelivrImage, making it a seamless transition for projects looking to optimize image delivery.

For example, in a Next.js application, if your images are stored in the public directory, they are typically accessed as:

<img src="/images/photo.jpg" alt="Example" />

By using StaticDelivrImage and configuring the baseURL to your website's domain, you can optimize these images effortlessly:

StaticDelivr.set({ baseURL: 'https://example.com' });

<StaticDelivrImage
  src="/images/photo.jpg"
  width={800}
  height={600}
  quality={85}
  format="webp"
  alt="Example"
/>

Here, the baseURL ensures that relative paths (e.g., /images/photo.jpg) are resolved to https://example.com/images/photo.jpg, streamlining image optimization and delivery.
