In this example, the directive uses the same scope, and stores the DOM element on the scope. It does not always get that bad, as you could store it in a variable. However, it would still take up memory if any closure that had referenced that variable or any other from the same function scope lived on. If you do that multiple times in one flow, it might start running slow. Consider calling $scope.$applyAsync() on the expressions instead. I believe that high performance of the front-end app is our primary goal.

Code Generation With Graphql Codegen#

Instead, it integrates into the existing Chrome DevTools as a new tab specifically for Angular. Using this tool, developers can inspect the states of elements and also examine performance and speed. The extension makes it much easier to follow the flow of the code and see whether everything is behaving as expected at each step.

The options panel also allows us view the Angular version of the app and what we’re using or not using from a CDN. We can fetch the injector of the current element by using the injector() method on the selected element. Adds a small AngularJS icon into the address bar when you come across a page that is built using AngularJS. Gauntlets is light, based onng.probe, loads instantly and does not need to switch to another tab of the Chrome DevTools. $count function prints number of Scopes, isolateScopes, listeners and watchers.

So doing a `scope.$destroy()` in the directive destroys the MainController’s scope which probably isn’t intended. If you isolate the directive’s scope the memory leak goes away. Here are the detailed instructions for Android And for iOS, unofficial guides are to be found easily through google.

Breaking Change Detection With Graphql Inspector#

You can still apply filters to the array, they will work just fine. Notice that attrs.watchAttribute is passed into scope.$watch() without the quotation marks! That means what was actually passed to $watch was the string MC.foo!

Once our installation is set, we can start up the extension by navigating to our developer tools and clicking enable to enable Batarang to start collecting debugging information about our page. As we can see, the source tab isn’t just a display of code, it allows editing the source code itself. We can set Chrome to sync between our real source code and the file being displayed on the source tab so that when we make changes from Chrome, it is saved into our source code. This can be extremely useful during debugging to directly fix small bugs quickly from within the browser.

Angular JS removes nearly all these boilerplate, leaving the code that defines the complete movement of the application instead of the execution particulars. Decoupling Document Object Model operation from the application logic. The exertion of this is intensely affected by the manner the given code is arranged. Its dependency injection excludes most of the codes that you ought to write additionally, in the first place.
