image-exif-analyzer
NPM library for extracting image EXIF metadata.
***Open source project by AlexLopEx03 under the MIT license*** 📜
---
> [!NOTE]
> This project is a wrapper for the Cargo library [kamadak-exif](https://crates.io/crates/kamadak-exif).
>
> Developed in Rust and prepared to WebAssembly using wasm-pack and wasm-bindgen, so it can be used in the browser client-side with very high performance.

### Installation and usage:
```Bash
npm install image-exif-analyzer
```
```Js
import extractMetadata from 'image-exif-analyzer'
const image = await fetch(image_url)
const metadata = await extractMetadata(image)
console.info(metadata) // -> {
// "DateTime": "2025-01-31 16:30:15",
// "Make": "iphone",
// "Model": "iPhone 13 Pro Max",
// "GPSLatitude": "37/1, 46/1, 5627/100",
// etc ...
// }
```
> [!WARNING]
> This library may not work in many development environments, sometimes it will only work in production environments, after being bundled.
>
> You can simulate the production environment with the following commands if you use Vite
>
> ```Bash
> npm run build & npm run preview
> ```
---
> [!TIP]
>
> - ### Exif metadata support:
> Although EXIF is supported, most applications such as social networks strip metadata from images for privacy reasons.
>
> Some applications that **do not** remove them include Drive, Gmail, and other email services or file managers.
