@tpmjs/official-base64-encode

Encode string or buffer to base64 format with support for multiple character encodings.

Installation

npm install @tpmjs/official-base64-encode

Usage

import { base64EncodeTool } from '@tpmjs/official-base64-encode';
import { generateText } from 'ai';

const result = await generateText({
  model: yourModel,
  tools: {
    base64Encode: base64EncodeTool,
  },
  prompt: 'Encode "Hello, World!" to base64',
});

Parameters

• data (string, required): The data to encode to base64
• encoding (string, optional): Character encoding of the input data
  • Options: 'utf8' (default), 'binary', 'hex'

Returns

{
  base64: string;        // The base64 encoded string
  byteLength: number;    // The byte length of the original data
}

Examples

Encode UTF-8 text (default)

const result = await base64EncodeTool.execute({
  data: 'Hello, World!',
});
// { base64: 'SGVsbG8sIFdvcmxkIQ==', byteLength: 13 }

Encode binary data

const result = await base64EncodeTool.execute({
  data: '\x00\x01\x02\x03',
  encoding: 'binary',
});
// { base64: 'AAECAw==', byteLength: 4 }

Encode hex string

const result = await base64EncodeTool.execute({
  data: 'deadbeef',
  encoding: 'hex',
});
// { base64: '3q2+7w==', byteLength: 4 }

Use Cases

• Encoding text for data URIs
• Preparing binary data for transmission
• Converting hex strings to base64
• Encoding authentication credentials
• Creating base64-encoded images or files
