Two-way Binding. By doing so, we make it easy to search a component belonging to the module You can create subfolders for directives, pipes under the module folder Data modeling helps in describing the structure, associations, constraints relevant to available data, and eventually encodes these rules into a reusable standard. The ideas presented in this article are based on extensive experience from a large enterprise environment (150 Angular SPAs and 30+ libs ) many of which consume our custom Angular component library!
