To create a minimalist background using the agenda package, you can use the following code:

const agenda = require('agenda');

// Create a new agenda instance
const app = new agenda();

// Define a simple job that runs every minute
app.define('minimalistBackground', {
  channel: 'background',
  on: 'rate(1m)',
  callback: async (job, done) => {
    // Generate a random background color
    const backgroundColor = Math.floor(Math.random() * 16777215).toString(16);
    const textColor = '#ffffff'; // White text color

    // Set the background color using the agenda package's built-in API
    app.background('minimalistBackground', {
      backgroundColor,
      textColor,
    });

    done();
  },
});

// Start the agenda instance
app.start((err) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Agenda started');
  }
});

This code defines a simple job that runs every minute and generates a random background color. The agenda package's built-in API is used to set the background color.

Note: This code assumes you have already installed the agenda package using npm or yarn.
