tru.ID SDK for React Native

The only purpose of the SDK is to force the data cellular connectivity prior to call a public URL, and will return the following JSON response

• Success When the data connectivity has been achieved and a response has been received from the url endpoint

{
"http_status": string, // HTTP status related to the url
"response_body" : { // optional depending on the HTTP status
           ... // the response body of the opened url 
           ... // see API doc for /device_ip and /redirect
                },
"debug" : {
    "device_info": string, 
    "url_trace" : string
          }
}

• Error When data connectivity is not available and/or an internal SDK error occurred

{
"error" : string,
"error_description": string,
"debug": {
    "device_info": string, 
    "url_trace" : string
          }
}

Potential error codes: sdk_no_data_connectivity, sdk_connection_error, sdk_redirect_error, sdk_error.

Usage

• Is the device eligible for tru.ID silent authentication?

import TruSdkReactNative, {
  ReachabilityResponse,
  CheckResponse,
  CheckErrorBody,
  CheckSuccessBody,
  ApiError,
  ReachabilityBody,
  ReachabilityResponseBody,
} from '@tru_id/tru-sdk-react-native';

// ...
// retrieve access token with coverage scope from back-end
const token = ...
// open the device_ip public API endpoint
    if (token) {
      const res =
        await TruSdkReactNative.openWithDataCellularAndAccessToken<ReachabilityResponse>(
          'https://eu.api.tru.id/coverage/v0.1/device_ip',
          true,
          token
        );
    if ('error' in res) {
      // error ${err.error_description}
    } else if ('http_status' in res) {
      const httpStatus = success.http_status;
      if (httpStatus === 200 && res.response_body !== undefined) {
        const body = res.response_body as ReachabilityBody
        // device is eligible on MNO  ${body.network_name}
      } else if (httpStatus === 400 && res.response_body !== undefined) {
        const body = res.response_body as ApiError;
        // MNO not supported ${body.detail}
      } else if (httpStatus === 412 && res.response_body !== undefined) {
        const body = res.response_body as ApiError;
        // Not a mobile IP ${body.detail}
      } else if (res.response_body !== undefined) {
        const body = res.response_body as ApiError;
        // other error see ${body.detail}
      }
    }
    }
