Express App

This package helps create custom middleware using express config

initialize

Constructor

new ExpressApp({
  app = express(),
  ...expressOptions
}, configureExpress = app => {})

Paremeters

• app: used for providing custom express instance.
• expressOptions: all those things can be set using app.set(key, value)
• configureExpress: function argument which will be called similar to configureExpress method.

expressOptions can be skipped altogether and only configureExpress may be used

example:

const customApp = new ExpressApp({
    views: './templates',
    'view engine': 'pug',
  },
  app => {
    app.use(bodyParser.urlencoded({ extended: true }));
    someOtherMethod(keystone, app);
  }
);

// OR when skipping expressOptions

new ExpressApp(app => {
  app.set(...);
  app.use(...);
  app.get(...);
  app.post(...);
})

Methods
