Occasionally, you may need to install npm packages while offline. This could be due to a flaky network connection, being on a flight or during a workshop. Getting this working has been a dream for a while.
They say you should follow your dreams. Unless it’s been a while and they haven’t followed you back, in which case unfollow them and move on. Luckily, there are a few options available to get npm working offline today.
In Angular, a Component is a special kind of directive that uses a simpler configuration which is suitable for a component-based application structure.
This makes it easier to write an app in a way that’s similar to using Web Components or using Angular 2’s style of application architecture.
Advantages of Components:
- simpler configuration than plain directives
- promote sane defaults and best practices
- optimized for component-based architecture
- writing component directives will make it easier to upgrade to Angular 2
When not to use Components:
- for directives that rely on DOM manipulation, adding event listeners etc, because the compile and link functions are unavailable
- when you need advanced directive definition options like priority, terminal, multi-element
- when you want a directive that is triggered by an attribute or CSS class, rather than an element
