Before we go in details, here it is important to define the Modular applications, its functionality and use. Modular applications are those applications, which are composed of sets of highly decoupled, distinct pieces of functionality stored in modules. Modules make application easier to use and maintain, the functionality can be easily swapped in and out, and this is always helpful in order to make an application as a successful application. The functionality of the modules sometimes is restricted to activation of one element, when other one is deemed to be viewable by the users, in this way, this is always one of the best things available. Smoothness, Linking, Scrolling, and navigation elements are some sorts of elements, which are not covered in the Modules formations.
Let’s build a ScrollSpy Module: Here we will mention the new module, by using the chained sequence rather than declaring a variable for the module is always given priority, so, here, we don’t give the pollute the global scope, and this is always one of the best thing, when modules have the same var.
Here we will mention that Scrollspybroadcast and Scrollspylisten, a directive, which sits on each content section and determines whether it’s been scrolled to active or not, this is always mean to serve the high programming. On the other hand, a directive, that sits on each navigation elements, and listen for the changes to the stack, this also triggers the class if it is the current active element.
There are also some of the major issues with the Scrollspy module in dynamic content, we could make use of the mutation observers, but they are not widely supported and used, but here is the polling, as a bad form. Here we will update the position to take advantage of Srootscope Swatch to watch for any digest calls received, but it has not included in the version this article will link to. Position factory will deal with the changes to save every single scrollspybroadcast directive from calculating document height and window position, and this all operation will be carried on by making use of scroll event in a run block. This is always a good option to develop the programing.
What we need to do for adding the module wide configuration:
Module wide configuration can take place by using value, provider and config block without littering our view with data attributes. The value block works as a default configuration for the module. The provider block allows us to expose API for application wide configuration. Now, it is possible to implement a cofig block in their application. The scrollspyconfigis then injected into it, and it gives the users access to manipulate the module configuration.Along with this, we inject value and provider block into the necessary directive, this is always one of the best options available.Nevertheless, we need to consider that configuration should be valid and authentic. Fortunately, the template property can adopt the function, which includes elements and Attrs.
