# Style Guide

The default style guide that is used in this project, is based on the Vue Style Guide and the Angular Style Guide.

# What is a Module?

A module is an encapsulated piece of domain logic in your application, this could be for example:

# Use-cases for a module

Dynamic page: consists of a lot of view logic, at least one route and state management

Static page: has no state management but a route e.g. /imprint

Domain logic with shared view components: e.g. authentication state, actions, mutations plus login/signup forms but no routes

Domain logic: just plain logic with state management but no routes and no components

A module usually has routing information, state management or both.

You can easily create modules with npm run generate

# What is a Connected Component?

A connected component is a Single File Component with VueX-mappings and it has to live inside a module.

(these components are different compared to normal components because it is required to set up a VueX mock store for testing)

# What is a Component?

This is a simple Single File Component without bindings, it just takes props and emits events - this is called a "stupid" component.

A Component can be placed everywhere. Usually, they live in the first level of a module, but it can also be inside other component folders.


You should try to have as many "stupid" components as possible. They are much easier to test because you can just pass test objects, values, stubs and mocks as a property. And they are much better to reuse!

If you want to know how to archive this, have a look at Container Components (in our vocabulary "Connected Components").

# Naming Conventions

Naming is one of the hardest things in software development. We cannot support you with perfect names because we don't know your domain but we can help you to be consistent in naming files, modules, CSS classes, etc.

Let's consider you create a new page (module) with state management, routes and a component named FooBar. What would be the different variations for different contexts?

  • module fooBar
  • route fooBar
  • connected component FooBar
  • css class fooBar // we decided against the hyphen notation because you have to use lower camel-case anyway to reference it with $style
  • actions FooBarActions
  • getters FooBarGetters
  • mutations FooBarMutations
  • state interface IFooBarState
  • default state FooBarDefaultState

Generator CLI

If you want to save some time and keep the style guide consistent, we recommended using the included Generator CLI to generate new code.
