# Vuex Terms

# Concept:

• State: app level state/data (eg: todo, posts ...)
• Getters: get pieces of state or computed values from state
• Actions: Called from components to trigger a mutation
• Mutations: mutate the state (update data)
• Modules: Each module can have its own state, getters, actions and mutations (post module, todos module)

# How it works

My current understanding (13/11/2020): create a store [step 0] --> create module for API related data (eg: todos) [step 1] --> create 4 basic methods inside module file (state, getters, actions, mutations) [step 2] --> create the action method and mutation method, so mutation method will be called by action method!!! (It something like chaining, coming together ...) [step 3] --> Go to component level, and start calling this module file defined action methods, interacting with vue directive methods (eg: @click, @change ...) [step 4] --> so far, we can see we generated a state tracking circle, from action -> mutation -> store [step 5]
