Context Settings

• Type: object
• Origin: Nullstack Context
• Availability: server/client
• readwrite in server context
• readonly in client context

You can use it to configure your application with public information.

You can assign any keys with any type to the object.

You can assign keys to settings dynamically based on current environment using context.environment.

// server.js
import Nullstack from 'nullstack';
import Application from './src/Application';

const context = Nullstack.start(Application);

context.start = function() {
  const { settings, environment } = context;
  settings.endpoint = 'https://domain.com/api';
  settings.publicKey = environment.development ? 'DEV_API_KEY' : 'PROD_API_KEY';
}

export default context;

// src/Application.njs
import Nullstack from 'nullstack';

class Application extends Nullstack {

  async hydrate({settings}) {
    const response = await fetch(settings.endpoint, {
      headers: {
        Authorization: `Bearer ${settings.publicKey}`
      }
    });
    this.data = await response.json();
  }

}

export default Application;

Any environment variable starting with NULLSTACK_SETTINGS_ will be mapped to the settings in that environment.

🐱‍💻 NULLSTACK_SETTINGS_PUBLIC_KEY will be mapped to settings.publicKey
