Importing Users with Auth0 Node.js SDK

Overview

This article details the process of importing users into Auth0 using the Node.js SDK. It specifically addresses how to transform a local file containing user data into a format compatible with Auth0’s import process.

When importing users to Auth0, the API typically expects user data to be provided as a file. In Node.js environments, particularly when dealing with data streams or blobs, it is crucial to ensure that the data is sent in the correct format to meet API requirements.

  • Auth0 Management API v2
  • Auth0 Node.js SDK

Solution

To import users from a local file, the data must be read from the file, converting the contents into a Blob object, and then passing this Blob to Auth0’s importUsers method. It is essential to monitor the job’s status to confirm the successful completion of the import.

  1. Read the user data file (e.g., CSV or JSON) using the Node.js’s fs.readFileSync method.
  2. Encapsulate the file’s content within a Blob object. This step is critical for Auth0 to recognize the data as a file.
  3. The ManagementClient.jobs.importUsers method should be invoked, providing the newly created Blob and the appropriate connection ID as parameters.

This code snippet demonstrates a basic approach to importing users into an Auth0 connection.

NOTE: This is a conceptual example provided for illustrative purposes. Users must customize this function to fit their specific use case, error handling, and environment setup. This includes how fs.readFileSync is used (Node.js environment), how Blob is handled, and how mn (Management API client) is initialized and configured with proper authentication.

async function importUsers(connection, data) {
  // Construct the full path to the data file.
  // `__dirname` refers to the directory of the current script.
  // `data` is expected to be the filename or relative path within that directory.
  const dataFilePath = join(__dirname, data);

  // Read the file synchronously from the file system.
  // The content is then wrapped in a Blob object, which is a file-like object
  // of immutable, raw data.
  let file = new Blob([fs.readFileSync(dataFilePath)]);

  // Call the Auth0 Management API to import users.
  // `mn` is assumed to be an initialized Auth0 ManagementClient instance.
  // The `importUsers` method takes the Blob of user data and the connection ID.
  let job = await mn.jobs.importUsers({
    users: file, // The Blob containing user data (e.g., a JSON file with user objects)
    connection_id: connection, // The ID of the Auth0 connection to import users into
  });

  // The `job` variable will contain information about the import job,
  // which users can then monitor for completion and status.
