Configuring the App

Before running this app, you need to set some config options. This is done through environment variables or by creating a .env file in the root of the project.

The following variables are available to be configured:

  • ACCESS_KEY
    Set this to your Access Key you created in mbed Device Connector. If you don't have an Access Key, please create it by the following procedure:
    1. Access https://connector.mbed.com/#accesskeys.
    2. Click Create New Access Key.

    3. Copy the access key you just created and use it in .env file.

  • PORT:
    Set this to override the default port for this example. The default port is 8080.

The .env file format is as follows:

ACCESS_KEY=<Your ACCESS KEY>
PORT=<Port to be overridden>

Configuring the App

Once you've configured the example, you need to install its dependencies. Open a terminal or command prompt and run the following command:

npm install

If all the dependencies successfully installed, you can now run the app by using the following command:

node app.js

You should receive the following output:

mbed Device Connector Quickstart listening at http://localhost:8080

Copy and paste the printed URL into your browser and you should see the following screen:
