  • The way we can mitigate this problem is to wrap our modules and controllers in an anonymous function.
  • Think of an anonymous function as a wrapper or a container to hold our modules and controllers.
  • The source code for the app.js file should look like the followingThe code above wraps the application in anonymous function and assigned to the variable call app2.
  • Now open the shoppingController.js in the controllers folder and wrap the shoppingController in anonymous function, the source code for the file should look like the following3.
  • Type int the following URL in your browser http://localhost:8000/ and you will see the followingIn order to see the application in your browser you must first run the npm start in your angular-seed folder firstIn this tutorial we’ve taken some steps to future proof our application so that we are…

  • Assuming that a reducer is matching on action type, we can invert the params so that each reducer is a pure function accepting state and an action.
  • This might call a Reducer action, but async functions do not directly change any state.Making a distinction between these two types of actions would be more helpful and less confusing that the above usage with thunks.
  • No More Action Types As VariablesWhy is it standard practice to treat action creators and reducers differently?
  • Action creators and reducers are two sides of the same coin.const ACTION_ONE = ‘ACTION_ONE’ is a redundant side effect of the separation of action creators and reducers.
  • Every action passes data through a payload key.Now from count.increment we can generate the action creator from just the reducer.

  • The question is, when does it make sense to lazy load an image?
  • But if an image is visible only later after scrolling, or if its part of a list/grid of images (think Google Images) then it makes sense to lazy load them.
  • We have a couple of methods on the instance: – – Since in our case we only have one element, either of them will work fine: – – First, we stop observing right after we set because the image is already loaded at that point and it wouldnt make sense…
  • If your interested in lazy loading images in your Vue apps, but not in implementing the intersection observer code yourself, you can check out the vue-clazy-load component.
  • Lazy Loading images can improve your page performance, in particular the page load time and time to interactive performance metrics.

  • Today, we are excited to launch Angular InstantSearch our newest library for easily creating search UIs in Angular applications.
  • After several requests from our users, we thought that Angular developers deserved a dedicated InstantSearch library.
  • With Angular InstantSearch, widgets can be used easily with Angular directives.
  • Angular InstantSearch provides an API letting you choose the rendering you want without having to rewrite all the search business logic code.
  • With Angular InstantSearch, widgets are nothing more than regular DOM elements.
