Seek App Version 2.x

Seek is an app for identifying plants and animals. It is available on iOS and Android., if you'd like to help out, please see CONTRIBUTING.

Requirements

Installation

  1. Make sure you're running the Node version specified in .nvmrc. Realm only works with certain versions of Node, so you will need this for local data storage.
  2. Install dependencies with npm install
  3. If building for iOS, run npx pod-install from within the ios directory.

Setup files

  1. Go to android/app/src/main/res/values and rename config.example.xml to config.xml (and change its values to match your API keys)
  2. Rename config.example.js to config.js and change the JWT secret.
  3. Add AR Camera model and taxonomy files.
    1. The sample model files are available in this small_model.zip file.
    2. On Android, these files are named small_inception_tf1.tflite and small_export_tax.csv. Create a camera folder within Android assets (i.e. android/app/src/debug/assets/camera) and place the files there.
    3. On iOS, these files are named small_inception_tf1.mlmodel and small_export_tax.json and should be added to the Resources folder in XCode.
  4. Add files to utility/commonNames to allow the AR camera to load common names in localized languages. The latest files are attached assets named commonNames.tar.gz in the latest Seek release page.
  5. For Fastlane, add .env file and corresponding JSON_KEY_ANDROID file, following example in .env.example.
  6. Add local.properties file to android folder with correct sdk path to build on an Android device.

Run build

  1. Run npm start
  2. Build locally to a device or simulator by running npm run ios or npm run android

Manual Linking

Most third-party libraries use autolinking as of React Native 0.60.0. Any exceptions are listed in the react-native.config.js file. Currently, react-native-inat-camera on Android is manually linked.

Tests

We currently have three kinds of tests:

  1. tests/integration: Tests the integration of multiple modules, e.g. a list of observation that makes requests to a mocked API, persists the response data in local storage, retrieves the data from local storage and renders components.
  2. tests/unit: Tests only specific modules, like a single component, or a hook.
  3. e2e: Tests user interactions on the finished app build running on the iOS simulator (see below).

Unit tests & integration tests

We're using Jest and React Native Testing Library for most of our tests.

# Run all tests
npm test

E2E tests

We're using Detox for E2E tests. If you want to run the e2e tests on your local machine (MacOS only), make sure you fulfill the RN development requirements, see above, and also follow the test-specific environment setup.

# Build the app and run the tests
npm run e2e

If you have built the app already for a previous test, and just want to run an updated test without changing the app code, you can run npm run e2e:test.

If you are running into some issues after the tests have been working for some time, try updating applesimutils with brew update && brew upgrade applesimutils.

Troubleshooting

  1. One common issue in React Native involves libraries not being found by the bundler. If this happens, try npx react-native clean-project to clear caches and reinstall node_modules and pods.

Translations

We do our translations on Crowdin. Head over to https://crowdin.com/project/seek and create an account, and you can start suggesting translations there. We regularly export translations from Crowdin and import them to this project.

Adding New Locales

When a language is at least 20% translated on Crowdin, follow these steps to enable it in the app.

  1. Import translation files into i18n.ts.
  2. Add localized names to utility/dictionaries/languageDict.js for users to be able to choose a locale in settings.
  3. Import languages in utility/dateHelpers.js so date strings can be correctly translated.
  4. Use staging to add new locales to seek_common_names.rb.
  5. Generate a compressed commonNames.tar.gz directory via staging and copy it to your local machine
  6. Spot check that common name translations look correct, then overwrite existing files in utility/commonNames.
  7. If needed, load additional files via addCommonNamesFromFile function in utility/commonNamesHelpers.js.
