How to build a recipe app using Vue.js and Vuex

In this tutorial, I’m going to show you how to create an elegant Recipe App using Vue2, Vuex, Vuetify and Cosmic JS. For the sake of understanding how to consume Restful API’s, this tutorial will show how to make AJAX (XHR) requests to the Cosmic JS API in order to retrieve, add, update, and delete data/media in our Cosmic JS buckets. Let’s get started.

Download the GitHub repo
Check out the demo

Prerequisites

You’ll need Node JS and npm. Make sure you already have them before you start.

Getting Started

Doing everything using the existing git repo

First of all, you have to be sure you have node > 6.x installed, than run the following commands:

npm install -g vue-cli

Browser window will open automatically once you’ll run the last command.

package.json will look like this.

}

What we’re installing and why

  1. We’re going to use vue and vuex libraries to create components and manage state.
  2. We’re using vue-router package to navigate between our components.
  3. We’re using vuetify package to create beautiful layouts using vue components.
  4. We’re going to use cosmicjs library to handle our requests to our Cosmic JS bucket.
  5. vue-wysiwyg is used for editor & vee-validate is used for form validation.

Building our app

Now we will set up our index.html in our root directory where we will change the favicon and you can add meta tags also.

Below is the index.html file. Only code block important here is to include the build script at the end of body tag and create a element **

**where vue will bootstrap your application.

<!DOCTYPE html>
<html lang="en">
 <head>
 <title>Recipes App</title>
 <meta charset="utf-8">
 <meta http-equiv="X-UA-Compatible" content="IE=edge">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">

 </head>
 <body>
 <div id="app"></div>
 <script src="./dist/build.js"></script>
 </body>
</html>

Setup main.js

As you may know main.js is main file that creates vue instance and render the first component.

import Vue from 'vue'
import VueRouter from 'vue-router'
import store from './vuex/store'
import App from './App.vue'
import Vuetify from 'vuetify'
import VeeValidate from 'vee-validate';
import wysiwyg from "vue-wysiwyg";
import RecipeList from './components/RecipeList.vue'
import RecipeSingle from './components/RecipeSingle.vue'
import './stylus/main.styl'
Vue.use(VueRouter)
Vue.use(Vuetify)
Vue.use(VeeValidate)
Vue.use(wysiwyg,{
 hideModules: { bold: true, table: true, image: true }
})
const routes = [
 { name: 'home', path: '/', component: RecipeList },
 { name: 'recipes', path: '/recipes', component: RecipeList },
 { name: 'recipe', path: '/recipe/:id', component: RecipeSingle }
];
const router = new VueRouter({
 routes
});
new Vue({
 store,
 el: '#app',
 router,
 render: h => h(App),
 beforeMount: function(){
 this.$store.dispatch("getRecipes");
 }
})

In first few lines I imported all the packages and components into the app. Vue.use() inject our package into vue so that we can use it. Vue.use(VueRouter) is including router in our app. Which will provide navigation for the app.

Routing

const routes = [
 { name: 'home', path: '/', component: RecipeList },
 { name: 'recipes', path: '/recipes', component: RecipeList },
 { name: 'recipe', path: '/recipe/:id', component: RecipeSingle }
];

These are our possible routes. Home and Recipes are for showing list of recipes. And /recpie/:idwill show the recipe.

Vue Instance

new Vue({
 store,
 el: '#app',
 router,
 render: h => h(App),
 beforeMount: function(){
 this.$store.dispatch("getRecipes");
 }
})

Here Vue instance is created. el: '#app' is the id of the element from index.html where vue will be injecting the app. store is vuex store. I will talk about vuex later. router is injecting router object. render: h => h(App) is telling app to inject App component first in the App.

Setup App.vue

\src\App.js is the first component that will render. I used vuetify components for UI and provided stylus for css. You can check their documentation here. Most important code block here to include router view in the template <router-view></router-view>. This piece of code will render the router and respective components based on routes.

Vuex

Moving ahead first I discuss about Vuex and why we should use that. You can obviously use simple state and props for smaller applications. But for large applications we must use some kind of state management like redux in React. Vuex is maintained by vue team and it is widely used. Today we will that. Below is the Vuex flow diagram that I will explain.

There are four main concepts in vuex.

  • State
  • Actions
  • Mutations
  • Getters

State is where our whole application state/data will be store. So how it will work? For example, you are using this store in you component and want to change some state value. You have to dispatch an action. Then actionwill commit the mutation and it will change the state. So why action is needed, we can change state directly in mutation. Action is very important. We need actions when we have to call any async function and then on its success change the state. In case of API we consume request in actions and commit mutation to change state. It is very simple but very import to follow.

Getters are simple getter function to get value of state in components. If you need one state value in different components so it is better to create getter for it and use that getter in component as computed property.

It is convention to create vuex folder and then create store.js in it. So I did the same and created src/vuex/store.js. Below is the store.js code:

import Vue from 'vue'
import Vuex from 'vuex'
import Request from '../common/request'
import _ from 'lodash';
Vue.use(Vuex)
// the root, initial state object
const state = {
 recipes: [
 ],
 status: {
 loading: false,
 success: false,
 error: false
 },
 categories: [
 "Dessert",
 "Meal"
 ],
 recipe: {
 metadata:{
 feature_image: {
 },
 ingredients:[]
 }
 },
 editForm: false,
 editting: false,
 pagination: {
 page: 1,
 limit: 12,
 total: 0
 }
}
// define the possible getters that can be applied to our state
const getters = {
 recipes(state){
 return state.recipes;
 },
 recipe(state){
 return (keyword) => _.find(state.recipes,['_id', keyword]);
 },
 recipeModel(state){
 return state.recipe;
 },
 loading(state){
 return state.status.loading;
 },
 editForm(state){
 return state.editForm;
 },
 categories(state){
 return state.categories;
 },
 editting(state){
 return state.editting;
 },
 pagination(state){
 return state.pagination;
 },
 page(state){
 return state.pagination.page;
 }
}
// define the possible mutations that can be applied to our state
const mutations = {
 SET_TOTAL(state,payload){
 state.pagination.total = Math.ceil(payload / state.pagination.limit);
 },
 SET_RECIPES(state,payload){
 state.recipes = payload;
 },
 SET_RECIPE(state,payload){
 state.recipe = payload;
 },
 ADD_RECIPE(state,payload){
 state.recipes.unshift(payload);
 },
 EDIT_RECIPE(state,payload){
 state.recipes = _.unionBy([payload],state.recipes,'_id');
 },
 DELETE_RECIPE(state,payload){
 _.remove(state.recipes, function (recipe) {
 return recipe._id === payload._id
 });
 },
 LOADING(state){
 state.status = {
 loading: true,
 success: false,
 error: false
 };
 },
 SUCCESS(state){
 state.status = {
 loading: false,
 success: true,
 error: false
 };
 },
 ERROR(state,payload){
 state.status = {
 loading: false,
 success: false,
 error: payload
 };
 },
 CLEAR_ERROR(state){
 state.status = {
 loading: false,
 success: false,
 error: false
 };
 },
 TOGGLE_EDITFORM(state,payload){
 state.editForm = payload;
 },
 ADD_INGREDIANT_RECIPE(state,payload){
 state.recipe.metadata.ingredients.push({
 ingredient: payload
 });
 },
 REMOVE_INGREDIANT_RECIPE(state,payload){
 state.recipe.metadata.ingredients.splice(payload, 1);
 },
 SET_RECIPE_IMAGE(state,payload){
 state.recipe.metadata.feature_image.url = payload;
 },
 SET_RECIPE_FILE(state,payload){
 state.recipe.metadata.feature_image.file = payload;
 },
 TOGGLE_EDITTING(state){
 state.editting = !state.editting;
 },
 SET_RECIPE_DEFAULT(state){
 state.recipe = {
 metadata:{
 feature_image: {
 },
 ingredients:[]
 }
 };
 },
 PAGINATE(state,payload){
 state.pagination.page = payload;
 }
}

// define the possible actions that can be applied to our state
const actions = {
 getRecipes(context){
 context.commit('LOADING');
 Request.getRecipes(context.getters.pagination).then(res => {
 context.commit('SET_RECIPES',res.objects.all || []);
 context.commit('SET_TOTAL',res.total || 0);

 .catch(e => {

 }
 else{

 }
 })
 .then((e) => {

}
// create the Vuex instance by combining the state and mutations objects
// then export the Vuex store for use by our components
export default new Vuex.Store({
 state,
 getters,
 mutations,
 actions
})

Config

src/config/config.js is the file to store the basic configuration to access cosmicjs bucket data using their api or npm package.

const config = {
 bucket: {
 slug: YOUR_BUCKET_SLUG,
 read_key: YOUR_BUCKET_READ_KEY,
 write_key: YOUR_BUCKET_WRITE_KEY
 },
 object_type: YOUR_OBJECT_TYPE,
 image_folder: IMAGE_FOLDER_SLUG
};
export default config;

Commons

In src/common/ I created three .js files inorder to structre my code and make it scalable. src/common/request.js file will use src/common/Cosmic.js package and make requests to provided endpoints and return Promises. src/common/paramMapping.js will create a request object in case of add and edit.

In src/common/Cosmic.js I extended the cosmic-js package as it was missing deleteMediaand sort functionality in getObjectsByType functions.

Note: I created a PR I hope it will be added out of the box in cosmic-js package.

Cosmic.js extended code is below.

import Cosmic from 'cosmicjs';
var api_url = 'https://api.cosmicjs.com';
var api_version = 'v1';
Cosmic.getObjectsByType = function(config, object, callback){
 var endpoint = api_url + '/' + api_version + '/' + config.bucket.slug + '/object-type/' + object.type_slug + '?read_key=' + config.bucket.read_key;
 if (object.limit) endpoint += '&limit=' + object.limit;
 if (object.skip) endpoint += '&skip=' + object.skip;
 if (object.locale) endpoint += '&locale=' + object.locale;
 if (object.sort) endpoint += '&sort=' + object.sort;
 fetch(endpoint)
 .then(function(response){
 if (response.status >= 400) {
 var err = {
 "message" : "There was an error with this request."
 }
 return callback(err, false);
 }
 return response.json()
 })
 .then(function(response){
 // Constructor
 var cosmic = {};
 var objects = response.objects;
 cosmic.objects = {};
 cosmic.objects.all = objects;
 cosmic.object = _.map(objects, keyMetafields);
 cosmic.object = _.keyBy(cosmic.object, "slug");
 cosmic.total = response.total;
 return callback(false, cosmic);
 });
};
Cosmic.deleteMedia = function(config, object, callback){
 var endpoint = api_url + '/' + api_version + '/' + config.bucket.slug + '/media/' + object.media_id;
 fetch(endpoint, {
 method: 'delete',
 headers: {
 'Content-type': 'application/json'
 },
 body: JSON.stringify(object)
 })
 .then(function(response){
 if (response.status >= 400) {
 var err = {
 'message': 'There was an error with this request.'
 }
 return callback(err, false);
 }
 return response.json()
 })
 .then(function(response){
 return callback(false, response);
 });
};
function keyMetafields(object){
 var metafields = object.metafields;
 if(metafields){
 object.metafield = _.keyBy(metafields, 'key');
 }
 return object;
}
export default Cosmic;

Components

In this application I created following components.

  • RecipeList.vue
  • RecipeSingle.vue
  • RecipeForm.vue

RecipeList.vue

RecipeList.vue is the main component. It will show the list of recipes in card view. Again I used vuetify components. It provides add, edit, delete and pagination functionality too. For edit & add I have used Modal/Dialog to open the form. That is present in RecipeForm.vuecomponent.

import {mapActions,mapGetters} from 'vuex';

This will map getter of vuex store to computed property of Vue and map actions to methods.
