EmblaCoreJS is a TypeScript/JavaScript library containing the core session functionality in Embla, a cross-platform mobile Icelandic-language voice assistant client. EmblaCoreJS is packaged both for modern browser and React Native environments.
For the Dart/Flutter library see EmblaCoreFlutter.
The bundled web version of EmblaCoreJS, along with a minified version, can be found in the releases. See the browser example for example usage.
Important note:
Using the library requires an API key for the Ratatoskur server instance you wish to communicate with. To prevent the Ratatoskur API key from being sent to clients, it is recommended you set up an API endpoint which proxies the Ratatoskur authentication token endpoint. See endpoint documentation here.
Use npm or yarn to install dependencies:
npm install
# Needed for web version
npm install recordrtc
# Needed for React Native version
npm install react-native-sound-player @dr.pogodin/react-native-audioTo build the project run:
npm run buildThis compiles the code into JavaScript libraries found in lib/web/ and lib/react-native.
Documentation can be generated by running:
npm run docsDocumentation is then found in docs/ (open docs/index.html in a browser).
Tests can be run with:
npm run testExamples can be found in the directories example/web and example/react-native.
Information on running them is found in the corresponding README.md files.
The React Native version of EmblaCoreJS is published to npm as @mideind/embla-core.
In order to work, apps making use of EmblaCoreJS must have permission to record audio.
iOS apps must add the following to their Info.plist file:
<key>NSMicrophoneUsageDescription</key>
<string>Microphone permission is required for speech recognition.</string>Android apps must have the following in their AndroidManifest.xml file:
<uses-permission android:name="android.permission.RECORD_AUDIO" />The app must also request permission to record audio from the user. This can be done using e.g. the react-native-permissions library.
