Web

Adds a middleware that is executed before an action.

Use this feature when you want to execute a custom middleware before the execution of an action. If you want to add a middleware for a specific web handler implementation then take a look at Web.beforeAction. All middlewares registered by this method are executed after addBeforeAuthAction.

Alternatively this method can be called directly from Mebo as Mebo.Handler.get('web').addBeforeAction(...)

In order to pass a values computed by a "before middleware" to the action you need to add the values to the handler session, so the action can read them later. The web handler is available under res.locals.web, for instance:

const web = res.locals.web;
web.session().setAutofill('customValue', 'myValue');

Where any input assigned with the autofill property 'someCustom' is going to be assigned with the 'something' value:

class MyAction extends Mebo.action{
  constructor(){
     super();
     // gets assigned with `something` value
     this.createInput('a: text', {autofill: 'customValue'});
  }
}

Adds a middleware that is executed before an action that requires authentication.

Use this feature when you want to execute a custom middleware before the execution of an action that requires authentication. If you want to add a middleware for a specific web handler implementation then take a look at Web.beforeAuthAction. All middlewares registered by this method are executed before addBeforeAction.

Use this feature to define the passportjs authentication middleware.

  }
}

Returns a list of middlewares which are executed before an action.

This method can be re-implemented by subclasses to include custom middlewares that are tied with a specific web handler implementation. By default it returns the middlewares added through Web.addBeforeAction

Clears all middlewares assigned to run before actions (beforeAction)

Returns a middleware designed to execute a webfied Web.webfyAction based on an arbitrary express route. Differently from Web.restful this method does not response the request, instead it's done through the responseCallback which passes the action error, result and the default middleware express arguments, for instance:

const app = express();
app.get(
   '/foo',
   Mebo.Handler.get('web').middleware('myRegisteredAction', (err, result, req, res) => {
     // ...
   })
);

Adds the restful support to the express app.

It works by registering the rest routes for the webfied visible actions (Web.webfyAction) to the express app. The response of actions executed through the rest support is done via the output method.

const app = express();
Mebo.Handler.get('web').restful(app);

or

const app = express();
Mebo.Handler.get('web').restful(app, '/api'); // adding a prefix for the rest routes

Makes an action available for requests.

By doing that the action gets visible for the restful and middleware support.

This method is called during Mebo.Handler.grantAction('web', ...)

Creates an instance of a reader for the current handler

This passes the Web.request to the reader.

Creates an instance of a writer for the current handler.

This passes the Web.response to the reader and the request.query.context as an option to the writer.
