encodeImage Documentation

Brief Description

encodeImage is a function that converts an image file to a Base64-encoded string representation.

Usage

To use encodeImage, you need to import it from the module where it's defined and provide the path to the image file you want to encode.

import { encodeImage } from './path/to/module';

Parameters

• imagePath (string, required): The file path to the image that needs to be encoded.

Return Value

Returns a string containing the Base64-encoded representation of the image.

Examples

// Example 1: Encoding a local image file
const encodedImage = encodeImage('./images/example.png');
console.log(encodedImage); // Outputs: Base64 string representation of the image

// Example 2: Using the encoded image in an HTML img tag
const imgSrc = `data:image/png;base64,${encodeImage('./logo.png')}`;
document.getElementById('myImage').src = imgSrc;

Notes or Considerations

• Ensure that the file path provided to encodeImage is correct and that the file exists.
• The function uses synchronous file reading, which may block the main thread for large files. Consider using an asynchronous version for better performance in production environments.
• The encoded string can be significantly larger than the original file size, so be mindful when working with large images or when storage/bandwidth is a concern.
• This function is useful for embedding images directly in HTML or CSS, or for sending image data over protocols that only support text.
