Sign in users in your own Node.js browserless application using the Device Code flow- Prepare app

  • Article

In this article, you create a new Node.js browserless application and add all the files and folders required. You'll need to create the app to complete the rest of the articles in this series. However, if you prefer using a completed code sample for learning, download the sample Node.js browserless application from GitHub.

Create a new Node.js application project

To build the Node.js browserless application from scratch, follow these steps:

  1. Create a folder to host your application and give it a name, such as ciam-sign-in-node-browserless-app.

  2. In your terminal, navigate to your project directory, such as cd ciam-sign-in-node-browserless-app and initialize your project using npm init This creates a package.json file in your project folder, which contains references to all npm packages.

  3. In your project root directory, create two files named authConfig.js and index.js. The authConfig.js file contains the authentication configuration parameters while index.js holds the application authentication logic.

After creating the files, you should achieve the following project structure:

       ciam-sign-in-node-browserless-app/
       ├── authConfig.js
       └── index.js
       └── package.json

Install app dependencies

The application you build uses MSAL Node to sign in users. To install the MSAL Node package as a dependency in your project, open the terminal in your project directory and run the following command.

    npm install @azure/msal-node
