Sessions

Sessions¶

Part of the Human Scoring use case.

A session is the stretch of interaction a classification is about. The SDK starts one at init. Tell the SDK when a session ends in a way only your app knows about — a logout or an account switch — so that one user's interaction is never counted toward the next user's classification.

When to use it¶

The user logs out
The user switches accounts
You need the current session id, for example to log it beside your own records

Prerequisites¶

The SDK is installed and initialized. See the Quick Start.

Usage¶

Start a new session¶

import * as Dea from '@dea/react-native';

await Dea.reset();

reset() ends the current session and starts a new one with a new id. Evidence collected before the reset does not count toward the new session's classification. Consent is not affected.

Read the current session¶

const info = await Dea.getSessionInfo();

console.log(info.session); // current session id, a UUID
console.log(info.sdk);     // { version, core }
console.log(info.device);  // { runtime, os, surface, pixelRatio, rotation, maxTouchPoints, sensorRate }

Shut the SDK down¶

await Dea.dispose();

dispose() stops capture and releases the SDK. After dispose(), calls reject as they do before init, until init is called again, which starts a new session.

Examples¶

Reset on logout¶

import * as Dea from '@dea/react-native';
import {authService} from './auth';

export async function logout(navigation: {reset: (state: object) => void}) {
  await authService.signOut();
  await Dea.reset();
  navigation.reset({index: 0, routes: [{name: 'Login'}]});
}
