You‘ll begin to notice as you build out your actions in Vuex, many of them will look quite similar. Creating a remove action looks almost the same as the add action except for using the axios.delete
method then filtering out the deleted todo once the response comes back.
Add a remove button to the todo list:
<template> <div> <form @submit.prevent="add(task)"> <input v-model="task" type="text" /> <input type="submit" value="ADD"> </form> <article class="pa3 pa5-ns"> <ul class="list pl0 ml0 center mw6 ba b--light-silver br2"> <li v-for="todo of todos" class="flex items-center ph3 pv3 bb b--light-silver"> <span class="flex-auto">{{todo.id}} {{todo.task}}</span> <button @click="remove(todo)"><img src="https://icon.now.sh/trash" alt="delete"></button> </li> </ul> </article> </div> </template> <script> import { mapState, mapActions } from ‘vuex‘ import {init} from ‘./shared‘ export default { fetch: init, computed: { ...mapState({ todos: (state) => state.todos }) }, data () { return { task: ‘Some data‘ } }, methods: { ...mapActions([ ‘add‘, ‘remove‘ ]) } } </script>
store/index.js:
import Vuex from ‘vuex‘ import axios from ‘axios‘ const store = () => new Vuex.Store({ state: { todos: [ ] }, mutations: { init (state, todos) { state.todos = todos }, add (state, todo) { state.todos = [ ...state.todos, todo ] }, remove (state, todo) { state.todos = state.todos.filter((t) => { return t.id !== todo.id }) } }, actions: { async add (context, task) { const commit = context.commit const res = await axios.post(‘https://todos-cuvsmolowg.now.sh/todos‘, { task, complete: false }) commit(‘add‘, res.data) }, async remove ({commit}, todo) { await axios.delete(`https://todos-cuvsmolowg.now.sh/todos/${todo.id}`) commit(‘remove‘, todo) } } }) export default store
