🎨 Creating an application

At a minimum, an app's metadata is the application's name, description, package ID, and version. A package ID must follow the format of company.app_name and must contain no capital letters, spaces, or symbols other than - and _. A demo application's metadata definition would look like this:

meta = {
    /* application name */
    name: 'Demo',
    
    /* application description */
    description: 'cool demo application :3',
    
    /* application icon */
    icon: 'https://placehold.co/400',
    
    /* package id */
    pkg: 'flow.demo',
    
    /* application version */
    version: '1.0.0'
}

An application also requires a function to run when the app is opened. The simplest way to show content in an application is the innerHTML property on the window's content.

async open () {
  const win = window.wm.createWindow({
    title: this.meta.name,
    icon: this.meta.icon,
    width: 700,
    height: 500
  })

  win.content.style.background = 'var(--base)'
  win.content.innerHTML = `
    <h1>Hello World!</h1>
    <p>This is my extra cool demo application.</p>
  `

  return win
}

Put these two together by creating demoapp.js in the Applications folder for your first application. Inside this file, you're going to define a class with two items inside.

• The meta property, which provides the application's metadata to FlowOS.
• The open method, which FlowOS will trigger when the application is opened.

The will be inside the "DemoApp" in this example, so it can be read by FlowOS.

export default class DemoApp {
  meta = {
    name: 'Demo',
    description: 'cool demo application :3',
    icon: 'https://placehold.co/400',
    pkg: 'flow.demo',
    version: '1.0.0'
  }
  
  async open () {
    const win = window.wm.createWindow({
      title: this.meta.name,
      icon: this.meta.icon,
      width: 700,
      height: 500
    })

    win.content.style.background = 'var(--base)'
    win.content.innerHTML = `
      <h1>Hello World!</h1>
      <p>This is my extra cool demo application.</p>
    `

    return win
  }
}

That's just about it for a simple application. Later on, you can add your masterpiece to an app repository!
