React Native Exify
A simple library to read and write image Exif metadata in React Native. Inspired from this thread.
Features
- ✅ Read Exif data from an image
- ✅ Write Exif data into an image
- ✅ Tags are typed and standardized
- ✅ Works with Expo and bare React Native projects
Installation
yarn add @lodev09/react-native-exify
Usage
import { writeAsync, readAsync, ExifTags } from '@lodev09/react-native-exify';
🧐 Reading Exif
// ...
const uri = 'file://path/to/image.jpg'
const tags = await readAsync(uri)
console.log(tags)
✍️ Writing Exif
const uri = 'file://path/to/image.jpg'
const newTags: ExifTags = {
GPSLatitude: 69.69,
GPSLongitude: 69.69,
UserComment: 'Someone wrote GPS here!',
}
const result = await writeAsync(uri, newTags)
console.log(result.tags)
[!NOTE] On IOS, writing exif into an Asset file will duplicate the image. IOS does not allow writing exif into an Asset file directly. If you're getting the photo from a camera, write it into the output file first before saving to the Asset library!
See example for more detailed usage.
