About this Repository

The @itwin/clash-detection-client package consists of thin wrapper functions for sending requests to the iTwin Clash Detection API. There are CRUD functions for the four components of clash detection: suppression rules, tests, runs and results. Define clash suppression criteria in suppression rules, define clash criteria in tests and add suppression rules, run the tests for versions of iModels, and retrieve the clash results. Visit the Clash Detection API for more details.

Authorization options

There are two ways to provide the authorization token for the wrapper functions:

1. Set accessToken in parameters object every time a wrapper function is called (as shown in usage examples below).

2. Provide a callback function to the ClashDetectionClient constructor. This callback will be called by the wrapper function if the accessToken parameter in Option 1 is not provided.

    import { ClashDetectionClient, ClashDetectionClientOptions } from "@itwin/clash-detection-client";

    public static initWrapperClient(accessToken: string, projectId: string): ClashDetectionClient {
      const options: ClashDetectionClientOptions = {};
      const accessTokenCallback = async () => this.getAccessToken();
      const clashDetectionClient: ClashDetectionClient = new ClashDetectionClient(options, accessTokenCallback);
    }

    public static async getAccessToken(): Promise<string> {
      return "Bearer ey..."
    }
