EXIF Data Updater

Just know: This script is for me, but can easily be hacked at for you!

This script allows you to read and update the EXIF data of JPEG (.jpg and .JPG) images within a specified directory. It specifically updates the date and time information in the EXIF data based on the "User Comment" attribute. Optionally, you can use this script to only output the EXIF data without updating it.

Getting Started

Prerequisites

• Node.js (Version 12 or later is recommended)
• exiftool-vendored - A Node.js wrapper for exiftool.
• luxon - A library for handling dates and times.

Installation

1. Clone the repository or download the index.js script.

2. Navigate to the directory where the index.js script is located.

3. Install the required dependencies by running:

   npm install exiftool-vendored luxon

4. Make sure you have the directory containing the images you want to process.

Configuration

In the index.js file, you need to set the directory path of the images you want to process. Edit the directoryPath variable accordingly.

const directoryPath = './Path/To/Photos';

Usage

There are two modes you can run the script in:

1. Update EXIF Data Mode (default): In this mode, the script reads the "User Comment" attribute in the EXIF data, extracts the date, and updates the relevant date fields in the EXIF data. It also updates the file's modification and access timestamps.

   Run the script with the command:

   node index.js

2. Output Tags Mode: In this mode, the script will only read and output the EXIF data without updating it. To use this mode, pass outputTags as an argument.

   Run the script with the command:

   node index.js outputTags
