FFMETADATA1 Parser

A utility module for parsing and writing FFMETADATA1 files.

Installation

npm install ffmetadata1

Usage

const { parseFFMetadata, writeFFMetadata } = require('ffmetadata1');

// Example: Parsing FFMETADATA1 from a file
parseFFMetadata('metadata.txt')
  .then((metadata) => {
    console.log(metadata);
  })
  .catch((error) => {
    console.error('Error parsing FFMETADATA1:', error);
  });

// Example: Writing FFMETADATA1 to a file
const metadata = {
  'section1': {
    'key1': 'value1',
    'key2': 'value2'
  },
  'section2': [
    {
      'key3': 'value3'
    },
    {
      'key4': 'value4'
    }
  ]
};

writeFFMetadata(metadata, 'output.txt')
  .then(() => {
    console.log('FFMETADATA1 file written successfully.');
  })
  .catch((error) => {
    console.error('Error writing FFMETADATA1:', error);
  });

API

parseFFMetadata(filePath?: string): Promise<object>

Parses FFMETADATA1 from a file or stdin and returns the parsed metadata object.

• filePath (optional): The path to the metadata file. If not provided, stdin will be used.

Returns a promise that resolves to the parsed metadata object.

const { parseFFMetadata } = require('ffmetadata1');

parseFFMetadata('metadata.txt')
  .then((metadata) => {
    console.log(metadata);
  })
  .catch((error) => {
    console.error('Error parsing FFMETADATA1:', error);
  });

writeFFMetadata(metadata: object, filePath?: string): Promise<void | string>

Writes FFMETADATA1 from the provided metadata object to a file or stdout.

• metadata: The metadata object to write.
• filePath (optional): The path to the output file. If not provided, stdout will be used.

Returns a promise that resolves when the write operation is complete. If a filePath is provided, it resolves to void. Otherwise, it resolves to the generated metadata string.

const { writeFFMetadata } = require('ffmetadata1');

const metadata = {
  'section1': {
    'key1': 'value1',
    'key2': 'value2'
  },
  'section2': [
    {
      'key3': 'value3'
    },
    {
      'key4': 'value4'
    }
  ]
};

writeFFMetadata(metadata, 'output.txt')
  .then(() => {
    console.log('FFMETADATA1 file written successfully.');
  })
  .catch((error) => {
    console.error('Error writing FFMETADATA1:', error);
  });
