Web Component Contribution Guidelines

[alizedebray]

Here is a list of the main topics that we could cover in the web components package contribution guidelines #581:

• Declaration and validation of props: using "check" functions to validate props with @watch and componentWillLoad
• Separation of components: how to choose between creating a sub-component or just using an optional slot
• Component nesting: how to check if the parent have the expected children or if the children have the expected parent
• Animation management: using the Web Animation API
• Style definition: how to split and include styles so as not to overload components
• Component testing: what is the minimum test requirement
• File structure and naming convention
