    • service, export service class, external source, data,
  • The components of the MEAN stack include the MongoDB database, Express.js (a web framework), Angular (a front-end framework), and the Node.js runtime environment.
  • For this project well need the following modules: – – express: Express module for the web server – mongoose: A popular library for MongoDB – bodyparser: Parses the body of the incoming requests and makes it available under req.body – cors: CORS middleware enables cross-origin access control to our web…

  • The project required me to write a directive for a canvas, get the Base64 image data when a user draws on it, and make it available to the controller of the page which contains the directive.
  • This boils down to the fact that you need to access the scope of a Directive from a page Controller and access the scope of a page Controller from a Directive.
  • Now lets say we have the following controller: – – And the following template: – – The problem: we would like to bind the count variable of myCtrl to the internalCount variable of the counter directive.
  • This can easily be solved by binding a variable from the controller to the scope of the directive.
  • Your directive should now look like this: – – And your template like this: – – You will find a working fiddle here with all the code to this quick tutorial on how to exchange data between a directive and controller in AngularJS.

  • Similarly, in the caseof ANGULAR, if we want to get data from any source, we use services.
  • If we talk about AngularJS, in this, we have five ways to create service, but in Angular 2, we just have one way or single service.
  • This SERVICE is decorated with @injectable .
  • Then use export service class to achieve it.
  • In this class I use decorator @Injectable that allows functionality of this class to be injected.
