Before Download Request Worker Code Sample

The following section provides a sample code for a Before Download Request worker.

export default async (
  context: PlatformContext,
  data: BeforeDownloadRequestRequest
): Promise<BeforeDownloadRequestResponse> => {
  let status: ActionStatus = ActionStatus.UNSPECIFIED;

  try {
    // The in-browser HTTP client facilitates making calls to the JFrog REST APIs
    //To call an external endpoint, use 'await context.clients.axios.get("https://foo.com")'
    const res = await context.clients.platformHttp.get(
      "/artifactory/api/v1/system/readiness"
    );

    // You should reach this part if the HTTP request status is successful (HTTP Status 399 or lower)
    if (res.status === 200) {
      status = ActionStatus.PROCEED;
      console.log("Artifactory ping success");
    } else {
      status = ActionStatus.WARN;
      console.warn(
        `Request is successful but returned status other than 200. Status code : ${res.status}`
      );
    }
  } catch (error) {
    // The platformHttp client throws PlatformHttpClientError if the HTTP request status is 400 or higher
    status = ActionStatus.STOP;
    console.error(
      `Request failed with status code ${
        error.status || "<none>"
      } caused by : ${error.message}`
    );
  }

  return {
    status,
    message: "Overwritten by worker-service if an error occurs.",
    modifiedRepoPath: data.metadata.repoPath,
  };
};
