Welcome to the fAPI Web App

In this article, we will explore how to build a web app using Vue.js with Vuex state management to interact with the fAPI (Fake API).

What is fAPI?

fAPI is a fake API that allows developers to simulate data fetching and manipulation without the need for a real backend server. It’s perfect for prototyping and testing your front-end applications without worrying about setting up a server.

Setting up the Project

To get started, make sure you have Node.js and npm installed on your system. You can create a new Vue project using the Vue CLI:

    $ npx @vue/cli create fapi-app
    $ cd fapi-app
    $ npm install vuex
  

Creating a Store with Vuex

Vuex is a state management library for Vue.js that helps you manage the state of your application in a centralized store. To create a store with Vuex, you can define your state, mutations, actions, and getters in a separate file:

    // store.js
    import Vue from 'vue';
    import Vuex from 'vuex';

    Vue.use(Vuex);

    export default new Vuex.Store({
      state: {
        todos: []
      },
      mutations: {
        addTodo(state, todo) {
          state.todos.push(todo);
        },
        removeTodo(state, index) {
          state.todos.splice(index, 1);
        }
      },
      actions: {
        fetchTodos({ commit }) {
          // Simulate fetching data from fAPI
          setTimeout(() => {
            const data = ['todo 1', 'todo 2', 'todo 3'];
            data.forEach(todo => commit('addTodo', todo));
          }, 1000);
        },
        deleteTodo({ commit }, index) {
          commit('removeTodo', index);
        }
      },
      getters: {
        getTodos(state) {
          return state.todos;
        }
      }
    });
  

Using Vue Components

With the store in place, you can now create Vue components that interact with the store using mapState, mapMutations, and mapActions helpers:

    // TodoList.vue
    
      

        

          

            {{ todo }} Delete
          
        
      
    

    
      import { mapState, mapActions } from 'vuex';

      export default {
        computed: {
          ...mapState(['todos'])
        },
        methods: {
          ...mapActions(['fetchTodos', 'deleteTodo']),
          fetchData() {
            this.fetchTodos();
          }
        },
        mounted() {
          this.fetchData();
        }
      };
    
  

Running the Application

Finally, you can run the Vue app using the Vue CLI and see the fAPI web app in action:

    $ npm run serve
  

Congratulations! You have successfully built a web app using Vue.js with Vuex state management to interact with the fAPI.
