Inspired from [this thread](https://github.com/mrousavy/react-native-vision-camera/issues/780). 8 | 9 | ## Features 10 | * ✅ Read Exif data from an image 11 | * ✅ Write Exif data into an image 12 | * ✅ Tags are typed and standardized 13 | * ✅ Works with Expo and bare React Native projects 14 | 15 | ## Installation 16 | 17 | ```sh 18 | yarn add @lodev09/react-native-exify 19 | ``` 20 | 21 | ## Usage 22 | 23 | ```ts 24 | import { writeAsync, readAsync, ExifTags } from '@lodev09/react-native-exify'; 25 | ``` 26 | 27 | ### 🧐 Reading Exif 28 | ```ts 29 | // ... 30 | const uri = 'file://path/to/image.jpg' 31 | 32 | const tags = await readAsync(uri) 33 | console.log(tags) 34 | ``` 35 | 36 | ### ✍️ Writing Exif 37 | ```ts 38 | const uri = 'file://path/to/image.jpg' 39 | const newTags: ExifTags = { 40 | GPSLatitude: 69.69, 41 | GPSLongitude: 69.69, 42 | UserComment: 'Someone wrote GPS here!', 43 | } 44 | 45 | const result = await writeAsync(uri, newTags) 46 | console.log(result.tags) 47 | ``` 48 | 49 | > [!NOTE] 50 | > On IOS, writing exif into an Asset file will duplicate the image. IOS does not allow writing exif into an Asset file directly. 51 | > If you're getting the photo from a [camera](https://github.com/mrousavy/react-native-vision-camera/), write it into the output file first before saving to the Asset library! 52 | 53 | See [example](example) for more detailed usage. 54 | 55 | ## Contributing 56 | Contributions are welcome! 57 | 58 | See the [contributing guide](CONTRIBUTING.md) to learn how to contribute to the repository and the development workflow. 59 | -------------------------------------------------------------------------------- /example/README.md: -------------------------------------------------------------------------------- 1 | # Getting Started 2 | 3 | >**Note**: Make sure you have completed the [React Native - Environment Setup](https://reactnative.dev/docs/environment-setup) instructions till "Creating a new application" step, before proceeding. 4 | 5 | ## Step 1: Setup the Application 6 | 7 | ```bash 8 | yarn setup 9 | ``` 10 | 11 | This will [prebuild](https://docs.expo.dev/workflow/prebuild/) the project. Prebuild means it will create the native `ios` and `android` for you to get started. 12 | 13 | ## Step 2: Modifying your App 14 | 15 | Now that you have successfully run the app, let's modify it. 16 | 17 | ### ⚛️ TS 18 | 19 | 1. Open `App.tsx` in your text editor of choice and edit some lines. 20 | 2. For **Android**: Press the R key twice or select **"Reload"** from the **Developer Menu** (Ctrl + M (on Window and Linux) or Cmd ⌘ + M (on macOS)) to see your changes! 21 | 22 | For **iOS**: Hit Cmd ⌘ + R in your iOS Simulator to reload the app and see your changes! 23 | 24 | ### 🍎 IOS 25 | 26 | Open `ios/ExifyExample.xcworkspace` in Xcode and run the project. Browse to _Pods -> Development -> Exify_ folder. Modify to your heart's content. You will need to rebuild the project to see your changes. 27 | 28 | ### 🤖 Android 29 | 30 | Open `android` in Android Studio and run the project. Browse to _android -> app -> src -> ... -> MainActivty.kt_. Modify to your heart's content. You will need to rebuild the project to see your changes. 31 | 32 | ## Congratulations! :tada: 33 | 34 | You've successfully run and modified your React Native App. :partying_face: 35 | 36 | ### Now

Please follow it in all your interactions with the project. Before contributing, please read the [code of conduct](./CODE_OF_CONDUCT.md). 6 | 7 | ## Development workflow 8 | 9 | This project is a monorepo managed using [Yarn workspaces](https://yarnpkg.com/features/workspaces). It contains the following packages: 10 | 11 | - The library package in the root directory. 12 | - An example app in the `example/` directory. 13 | 14 | To get started with the project, run `yarn` in the root directory to install the required dependencies for each package: 15 | 16 | ```sh 17 | yarn 18 | ``` 19 | 20 | > Since the project relies on Yarn workspaces, you cannot use [`npm`](https://github.com/npm/cli) for development. 21 | 22 | The [example app](/example/) demonstrates usage of the library. You need to run it to test any changes you make. 23 | 24 | It is configured to use the local version of the library, so any changes you make to the library's source code will be reflected in the example app. Changes to the library's JavaScript code will be reflected in the example app without a rebuild, but native code changes will require a rebuild of the example app. 25 | 26 | If you want to use Android Studio or XCode to edit the native code, you can open the `example/android` or `example/ios` directories respectively in those editors. To edit the Objective-C or Swift files, open `example/ios/ExifyExample.xcworkspace` in XCode and find the source files at `Pods > Development Pods > react-native-exify`. 27 | 28 | To edit the Java or Kotlin files, open `example/android` in Android studio and find the source files at `react-native-exify` under `Android`. 29 | 30 | You can use various commands from the root directory to work with the project. 31 | 32 | To start the packager: 33 | 34 | 35 | To run the example app on Android: 36 | 37 | ```sh 38 | yarn example android 39 | ``` 40 | 41 | To run the example app on iOS: 42 | 43 | ```sh 44 | yarn example ios 45 | ``` 46 | 47 | Make sure your code passes TypeScript and ESLint. Run the following to verify: 48 | 49 | ```sh 50 | yarn typecheck 51 | yarn lint 52 | ``` 53 | 54 | To fix formatting errors, run the following: 55 | 56 | ```sh 57 | yarn lint --fix 58 | ``` 59 | 60 | Remember to add tests for your change if possible. Run the unit tests by: 61 | 62 | ```sh 63 | yarn test 64 | ``` 65 | 66 | ### Commit message convention 67 | 68 | We follow the [conventional commits specification](https://www.conventionalcommits.org/en) for our commit messages: 69 | 70 | - `fix`: bug fixes, e.g. fix crash due to deprecated method. 71 | - `feat`: new features, e.g. add new method to the module. 72 | - `refactor`: code refactor, e.g. migrate from class components to hooks. 73 | - `docs`: changes into documentation, e.g. add usage example for the module.. 74 | - `test`: adding or updating tests, e.g. add integration tests using detox. 75 | - `chore`: tooling changes, e.g. change CI config. 76 | 77 | Our pre-commit hooks verify that your commit message matches this format when committing. 78 | 79 | ### Linting and tests 80 | 81 | [ESLint](https://eslint.org/), [Prettier](https://prettier.io/), [TypeScript](https://www.typescriptlang.org/) 82 | 83 | We use [TypeScript](https://www.typescriptlang.org/) for type checking, [ESLint](https://eslint.org/) with [Prettier](https://prettier.io/) for linting and formatting the code, and [Jest](https://jestjs.io/) for testing. 84 | 85 | Our pre-commit hooks verify that the linter and tests pass when committing. 86 | 87 | ### Publishing to npm 88 | 89 | We use [release-it](https://github.com/release-it/release-it) to make it easier to publish new versions.
