Build a Simple CRUD App with Spring Boot and Vue.js

Build a Simple CRUD App with Spring Boot and Vue.js

Build a Simple CRUD App with Spring Boot and Vue.js. In this tutorial, you're going to build a complete CRUD web application using Vue.js for the client and Spring Boot as the resource server.

In this tutorial, you’re going to build a complete CRUD web application using Vue.js for the client and Spring Boot as the resource server. You’ll also secure the application using OAuth 2.0 and Okta.

CRUD is Create, Read, Update, and Delete. It’s kinda the “Hello World” of the server world. Like “Hello server!” If you can add data, updated it, read it, and delete it, you’ve pretty much got all the basic tools down for a REST interface or basic resource API.

The example application you’re going to build is a simple todo app. Typically these todo apps use data stored locally, but in this example you’re going to create, read, update, and delete todos on a Spring Boot resource server.

Excited? Great! Before we dive in, a quick introduction to the technologies involved.

What is Vue.js?

Vue is a JavaScript view library, like React and Angular. It’s designed to be incrementally adoptable, and the core library focuses solely on the view layer.

In my experience, Vue.js is a great alternative to React. I learned React first, and came to use Vue later. Like React, Vue uses a virtual DOM, provides reactive and composable view components, and enforces a strict one-way parent-child relationship when defining properties and state. This means that it is performant and it avoids a lot of the confusing state relationships that can occur without one-way data binding. However, unlike React, Vue uses templates instead of JSX (a potentially welcome and more immediately accessible option) and Vue gives you component scoped css using style tags in single-file components. In practice this difference is pretty great because in React the JSX and css-like syntax is close enough to HTML and CSS to be confusing but not actually the same, which creates problems initially (ever gone from a language that doesn’t require semicolons back to one that does? It’s something like that).

I find Vue to be a simpler, cleaner implementation. React requires a deep dive. You gotta take the red pill and go all the way. It’s a super powerful system, but you have to be all in. Vue is a little friendlier and a little easier to get started.

About Spring Boot

The server technology you’re going to use is Spring Boot. Pure, unadulterated Spring (pre-Spring Boot) is a bit of a behemoth: super powerful but potentially time-sucking and frustrating. I’m pretty sure the whole computer conference phenomena came about so that people could learn and understand old-school Spring XML files. It certainly drove large sections of the computer publishing empires.

Spring Boot was Spring’s answer to this complexity (and to frameworks like Ruby on Rails and Grails). They did a great job of distilling down all of the power of Spring into a simple, quick, easy-to-use web framework. With a ridiculously small number of lines of code and a few annotations, you can have a fully functioning resource server.

Plus, when you’re ready, f have all the power of Spring under the hood, just waiting.

For this project you’re going to need a server and client project. Create a root project directory called SpringBootVueApplication, and under that directory create two subdirectories: client and server.

client will be your Vue.js client application.

server will be the Spring Boot resource server.

Create Your Spring Boot App

Let’s start by creating the Spring Boot app using the Spring Initializer.

Make the following selections:

  • Project Type: Gradle Project
  • Group: com.okta
  • Artifact: spring-boot-vue
  • Dependencies: JPA, H2, Web, Rest Repositories, Lombok

Download the file and unzip the contents to your SpringBootVueApplication/server directory.

First off, let’s start with something simple. Change the default port from 8080 to 9000 (so that it doesn’t conflict with the Vue.js app client port in a bit).

Change the name of the server/src/main/resources/application.properties file to application.yml, and add the following line to it:

server:  
  port: 9000


Define the Todo Model Class

Let’s define the Todo model class file. This defines the data structure that your Spring Boot application will be using.

Create a Todo.java class in the com.okta.springbootvue package under src/main/java.

package com.okta.springbootvue;  

import lombok.*;  

import javax.persistence.Id;  
import javax.persistence.GeneratedValue;  
import javax.persistence.Entity;  

@Entity  
@Data  
@NoArgsConstructor  
public class Todo {  

  @Id @GeneratedValue  
  private Long id;  

  @NonNull
  private String title;  

  private Boolean completed = false;

}


This is pretty straight forward. You’re defining a data model with a three properties: an autogenerated id, a String title, and a true/false completed property.

Lombok is saving you a lot of wordy ceremony code defining getters and setters. Those are all the annotations tacked onto the class.

A whole lot of heavy hitting is happening here in the background that allows Spring Data and JPA to automatically map this class file to a database. This is a deep subject, and there are links at the end of the tutorial if you want to know more. For right now, it’s enough to know that the class above will be mapped to a database table in an in-memory H2 database, and each property in the class will become a table column. You get the in-memory database by default with the included dependency: H2. This is super convenient for tutorials and testing, but, obviously, for much more you’ll want to include a mapping to an actual persisted database.

Define the Database and REST Classes

Create a TodoRepository.java in the com.okta.springbootvue package.

package com.okta.springbootvue;  

import org.springframework.data.jpa.repository.JpaRepository;  
import org.springframework.data.rest.core.annotation.RepositoryRestResource;  

@RepositoryRestResource  
interface TodoRepository extends JpaRepository<Todo, Long> {}


This class is dead simple. Again, there’s a ton of stuff going on behind the scenes. All of the methods we’ll need for the REST API for our Todo app will actually be automatically generated for us here. You could, however, define some custom access methods in this class if you needed to.

Let’s also create a RestRepositoryConfigurator class in the same package.

package com.okta.springbootvue;

import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurer;
import org.springframework.stereotype.Component;

/**
 * IDs are not returned by RestRepository by default. I like them exposed so that the client can easily find
 * the ID of created and listed resources.
 * */
@Component
public class RestRepositoryConfigurator implements RepositoryRestConfigurer {

  @Override
  public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    config.exposeIdsFor(Todo.class);
  }
}


This class is just a configuration class. The whole purpose of it is to tell Spring to return the data model instance IDs with the the object serializations (that way you can refer to them by ID from the client app, since this is going to be the UUID).

Test the Rest API Server

At this point, believe it or not, you have a working REST API.

Let’s test it out using HTTPie. If you don’t have HTTPie installed, install it using brew install httpie. Or head over to their website and make it happen. Or just follow along.

First off, start the server using ./gradlew bootRun.

You should see a lot of output that ends like this:

2018-11-08 21:20:36.614  INFO 56214 --- [nio-9000-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/]       : Initializing Spring FrameworkServlet 'dispatcherServlet'
2018-11-08 21:20:36.615  INFO 56214 --- [nio-9000-exec-1] o.s.web.servlet.DispatcherServlet        : FrameworkServlet 'dispatcherServlet': initialization started
2018-11-08 21:20:36.646  INFO 56214 --- [nio-9000-exec-1] o.s.web.servlet.DispatcherServlet        : FrameworkServlet 'dispatcherServlet': initialization completed in 31 ms
<=========----> 75% EXECUTING [2m 59s]
> :bootRun


Now perform a basic GET request on the server endpoint: http GET http://localhost:9000

HTTP/1.1 200
Content-Type: application/hal+json;charset=UTF-8
Date: Fri, 09 Nov 2018 03:44:37 GMT
Transfer-Encoding: chunked
{
  "_links": {
    "profile": {
      "href": "http://localhost:9000/profile"
    },
    "todos": {
      "href": "http://localhost:9000/todos{?page,size,sort}",
      "templated": true
    }
  }
}


The profile link has to do with the ALPS (Application-Level Profile Semantics). Take a look at the Spring docs on it. It’s a way to describe the available resources exposed by the REST API.

The todos link is the endpoint generated from the Todo class.

Take a look at that endpoint using a GET request. You can actually omit the “GET”, and the “http://localhost” since these are defaults with HTTPie.

$ http :9000/todos
HTTP/1.1 200
Content-Type: application/hal+json;charset=UTF-8
Date: Fri, 09 Nov 2018 03:50:12 GMT
Transfer-Encoding: chunked
{
  "_embedded": {
    "todos": []
  },
  "_links": {
    "profile": {
      "href": "http://localhost:9000/profile/todos"
    },
    "self": {
      "href": "http://localhost:9000/todos{?page,size,sort}",
      "templated": true
    }
  },
  "page": {
    "number": 0,
    "size": 20,
    "totalElements": 0,
    "totalPages": 0
  }
}


The _embedded.todos holds the data. But since there aren’t any todos yet, it’s empty.

You can POST some data to the server using the following command:

http POST :9000/todos title="Write Vue client app"

The output will show your new Todo has been added:

HTTP/1.1 201
Content-Type: application/json;charset=UTF-8
Date: Fri, 09 Nov 2018 03:51:22 GMT
Location: http://localhost:9000/todos/1
Transfer-Encoding: chunked
{
    "_links": {
        "self": {
            "href": "http://localhost:9000/todos/1"
        },
        "todo": {
            "href": "http://localhost:9000/todos/1"
        }
    },
    "completed": false,
    "id": 1,
    "title": "Write Vue client app"
}


Todo created! Now if you GET the /todos endpoint again, you’ll see your newly created todo.

$ http :9000/todos
HTTP/1.1 200
Content-Type: application/hal+json;charset=UTF-8
Date: Fri, 09 Nov 2018 03:54:40 GMT
Transfer-Encoding: chunked
{
"_embedded": {
  "todos": [
    {
      "id": 1,
      "title": "Write Vue client app",
      "completed": false,
      "_links": {
        "self": {
          "href": "http://localhost:9000/todos/1"
        },
        "todo": {
          "href": "http://localhost:9000/todos/1"
        }
      }
    }
  ]
},
...
}


Pretty amazing, huh? That’s a whole lot of functionality for not a lot of code. (It didn’t used to be that way, let me tell you. We used to have to code uphill both ways in the rain and in PERL using vi to get stuff like that working. And you could have painted a house with all the getters and setters and ceremony code. Hours and hours.)

Add CORS Filter to Your Spring Boot App

Before you move on to the Vue client app, there’s one more thing to update. Currently, the server application would throw a CORS error if you tried to use it with a single-page app framework like Vue. This can be fixed by adding a CORS filter to the SpringBootVueApplication class.

What is CORS? If you’re asking this, read up on it in Spring’s Understanding CORS docs.

Update your SpringBootVueApplication class to match below. Notice the URL defined in the simpleCorsFilter() method needs to match the URL of the client app.

package com.okta.springbootvue;

import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.core.Ordered;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import java.util.Collections;
import java.util.stream.Stream;

@SpringBootApplication  
public class SpringBootVueApplication {  

    public static void main(String[] args) {  
      SpringApplication.run(SpringBootVueApplication.class, args);  
    }  

    // Bootstrap some test data into the in-memory database
    @Bean  
    ApplicationRunner init(TodoRepository repository) {  
        return args -> {  
            Stream.of("Buy milk", "Eat pizza", "Write tutorial", "Study Vue.js", "Go kayaking").forEach(name -> {  
                    Todo todo = new Todo();  
                    todo.setTitle(name);  
                    repository.save(todo);  
            });  
            repository.findAll().forEach(System.out::println);  
        };  
    }  

    // Fix the CORS errors
    @Bean
    public FilterRegistrationBean simpleCorsFilter() {  
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();  
        CorsConfiguration config = new CorsConfiguration();  
        config.setAllowCredentials(true); 
        // *** URL below needs to match the Vue client URL and port ***
        config.setAllowedOrigins(Collections.singletonList("http://localhost:8080")); 
        config.setAllowedMethods(Collections.singletonList("*"));  
        config.setAllowedHeaders(Collections.singletonList("*"));  
        source.registerCorsConfiguration("/**", config);  
        FilterRegistrationBean bean = new FilterRegistrationBean<>(new CorsFilter(source));
        bean.setOrder(Ordered.HIGHEST_PRECEDENCE);  
        return bean;  
    }   
}


The keen among you will also notice the ApplicationRunner init(TodoRepository repository) function. This bean is an initialization hook that adds some test todos into the repository when the application is run. This will make life easier as you’re building the client app.

On to the client app!

Install Node & Yarn

This tutorial assumes that you have Node and Yarn installed. If you don’t, install them now.

Yarn can be installed using brew install yarn, or if you’re not on a Mac, take a look at their website.

There are lots of ways to install Node.js. You can download a version from their website. I’m currently on version 8.12.0. Another option is the n package manager. Get it from their GitHub page.

Create Vue.js App

You’re going to use the Vue CLI 3 to create a project from scratch. Vue CLI is a great project that makes building a Vue app nice and easy. If you’re not familiar with it, take a look at their website.

Install the Vue CLI 3 using yarn:

yarn global add @vue/[email protected]


Once that’s finished, make sure you’re in your root project directory SpringBootVueApplication and run the following command:

vue create -d client


This creates the default Vue application named client in the client subdirectory. Without the -d option, the Vue CLI has a pretty neat interface that allows you to choose which options to include. It’s worth checking out another time. The project you’re going to build is based on the Vue TodoMVC example project by Evan You. The difference is that this project will persist the todos using a Spring Boot server instead of browser local storage.

cd into the SpringBootVueApplication/client directory.

The project can be run with yarn serve.

Right now, all you’ll see is the standard “Welcome to Your Vue.js App” screen.

Add a couple dependencies:

yarn add [email protected] [email protected]


axios is the package you’ll use to make HTTP requests to your server. vuejs-logger is a logging framework, because you’re not still using console.log(), right?

Add a Vue config file client/vue.config.js:

module.exports = {
  runtimeCompiler: true
};


Replace src/main.js with the following

import Vue from 'vue'
import App from './App'

Vue.config.productionTip = false

import VueLogger from 'vuejs-logger';

const options = {
  isEnabled: true,
  logLevel : 'debug',
  stringifyArguments : false,
  showLogLevel : true,
  showMethodName : false,
  separator: '|',
  showConsoleColors: true
};

Vue.use(VueLogger, options);

/* eslint-disable no-new */
new Vue({
  el: '#app',
  template: '<App/>',
  components: { App }
});


Replace src/App.vue with the following:

<template>
  <div id="app">
    <Todos />
    <footer class="info">
      <p>Based on a project written by <a href="http://evanyou.me">Evan You</a></p>
      <p>Original Vue TodoApp project is <a href="https://vuejs.org/v2/examples/todomvc.html">here</a></p>
      <p>Modified for this tutorial by Andrew Hughes</p>
    </footer>
  </div>
</template>

<script>
  import Todos from './components/Todos'
  // app Vue instance
  const app = {
    name: 'app',
    components: {
      Todos
    },
    // app initial state
    data: () => {
      return {
      }
    }
  }

  export default app
</script>

<style>
  [v-cloak] { display: none; }
</style>


Delete the src/components/HelloWorld.vue module. You can also delete the src/assets folder, if you want, as you won’t need it.

Create a new Vue component called src/components/Todos.vue:

<template>
  <div>
    <h1 class="title">Todos</h1>
    <h1 class="email">{{userEmail}}</h1>
    <section class="todoapp">
      <div v-if="loading">
        <h1 class="loading">Loading...</h1>
      </div>
      <div v-else>
        <header class="header">
          <input class="new-todo"
                 autofocus autocomplete="off"
                 :placeholder="this.inputPlaceholder"
                 v-model="newTodo"
                 @keyup.enter="addTodo">
        </header>
        <section class="main" v-show="todos.length" v-cloak>
          <input class="toggle-all" type="checkbox" v-model="allDone">
          <ul class="todo-list">
            <li v-for="todo in filteredTodos"
                class="todo"
                :key="todo.id"
                :class="{ completed: todo.completed, editing: todo == editedTodo }">
              <div class="view">
                <input class="toggle" type="checkbox" v-model="todo.completed" @change="completeTodo(todo)">
                <label @dblclick="editTodo(todo)">{{ todo.title }}</label>
                <button class="destroy" @click="removeTodo(todo)"></button>
              </div>
              <input class="edit" type="text"
                     v-model="todo.title"
                     v-todo-focus="todo == editedTodo"
                     @blur="doneEdit(todo)"
                     @keyup.enter="doneEdit(todo)"
                     @keyup.esc="cancelEdit(todo)">

        <footer class="footer" v-show="todos.length" v-cloak>
          <span class="todo-count">

          <ul class="filters">

    }
  }

  export default Todos
</script>

<style>
  [v-cloak] { display: none; }
</style>


Finally, add a stylesheet called public/style.css and copy and paste the styles from the stylesheet in our GitHub repository..

In the public/index.html, add the following line at the bottom of the block.

<link rel="stylesheet" type="text/css" href="<%= BASE_URL %>style.css">


If you do this now, you’ll see a functioning todo application, but the data doesn’t persist. The todos are simply saved as an array in the Vue module. You’re going to modify this to send and receive data from your Spring Boot resource server.

Add Client Logic to Handle API Requests

Under the client/src directory, add a file named Api.js with the following contents:

import axios from 'axios'  

const SERVER_URL = 'http://localhost:9000';  

const instance = axios.create({  
  baseURL: SERVER_URL,  
  timeout: 1000  
});  

export default {  
  // (C)reate  
  createNew: (text, completed) => instance.post('todos', {title: text, completed: completed}),  
  // (R)ead  
  getAll: () => instance.get('todos', {  
    transformResponse: [function (data) {  
      return data? JSON.parse(data)._embedded.todos : data;  
    }]  
  }),  
  // (U)pdate  
  updateForId: (id, text, completed) => instance.put('todos/'+id, {title: text, completed: completed}),  
  // (D)elete  
  removeForId: (id) => instance.delete('todos/'+id)  
}


This file encapsulates some of the logic around the REST API requests. The SERVER_URL should be the URL and port of the Spring Boot server.

You’ll notice the CRUD (Create, Read, Update, and Delete) functions are defined. This module would be totally trivial, really, except for the transformResponse options you’re setting. This is just used to normalize the data in the _embedded response property.

You might be wondering why to even bother with an API class this simple, thinking that this code could easily have just been put into the Todos component. That’s true, for the purposes of this tutorial. However, as projects grow, this kind of encapsulation is what keeps a project maintainable over time.

For example, suppose at some point in the future you decided that you didn’t want to use the axios module, or your boss told you to switch it out for fetch; you’d feel pretty smart when you realized that all of the code is handily gathered in one place and you’re only going to have to edit one file (as opposed to searching and replacing all over the project).

Load Data From the Server

Now you need to change the Todos component (src/components/Todos.vue) so that it loads data from the Spring Boot REST server.

First thing is to import the Api module you just created. Beneath the section, just below the

Ember.js vs Vue.js - Which is JavaScript Framework Works Better for You

Ember.js vs Vue.js - Which is JavaScript Framework Works Better for You

In this article we will discuss full details and comparison of both Ember.js and Vue.js

JavaScript was initially created to work for web applications. But today they have become the favorite of mobile app developers. Most of the developers prefer to work with frameworks based on JavaScript. It simplifies coding. You can use JavaScript with almost any framework.

The use of a particular framework will decide how easy and fast it is to create the app. So, you must choose the best one suited for the app that you are planning to build. You must make a wise choice so that you benefit in the end. Among the crowded market, two of the frameworks stand out. We will make a comparison between Ember.js and Vue.js.

Why Do You Select A Particular Framework?

Before we start comparing the two frameworks, we should understand the factors that lead to the choice of a framework. Each developer chooses a framework before he or she goes to work on an app. Let us see the reasons for the selection.

● The codes must be easy to understand and transparent.

● The framework should give the maximum power with the least amount of coding.

● The framework should provide a well laid out structure to work on.

● Does the framework support an in-built router or an external plug-in router?

● The framework should be able to transfer more data on a full page-load so that it becomes a single-page app. A single-page app is more beneficial for the application.

● In single page architectures if there is a need for users to share links to sub-screens within the interface, then the framework should have the capacity to route based on the URL.

● A tighter template option can help in enabling two-way binding.

● The framework should not conflict any third-party library.

● Testing the codes inside the framework should be easy.

● The framework should provide the HTTP client service for AJAX calls

● The documentation is essential. It should be complete and up-to-date.

● The framework should be compatible with the latest version of the browser.

● The framework has to fulfill the above conditions for easy construction of the app. You must ensure that the framework you choose meets the conditions.

Vue.js Explained

Developers are always looking at new frameworks to build their apps. The main requirements are speed and low cost. The framework should be easy to use by even new developers. You should be able to use it at low cost. Other considerations are about simple coding, proper documentation, etc.

Vue.js combines a lot of good when it comes to software language for web app development. The architecture of Vue.js is easy to put in use. The apps developed using Vue.js are easy to integrate with new apps.

Vue.js is a very lightweight framework. It makes it fast to download. It is also much faster than other frameworks. The single-file component nature of the framework is also beneficial. The size has made it very popular.

You can further decrease weight. With Vue.js you can separate the template-to-virtual DOM and compiler. You can only deploy the minified and zipped interpreter which is only 12 KB. You can compile the templates in your machine.

Another significant advantage of Vue.js is that it can integrate easily with existing applications created with JavaScript. It will make it easy for using this framework to make changes to applications already present.

Vue.js also integrates easily with other front-end libraries. You can plug in another library and make up for any deficiency in this framework. This feature makes this tool a versatile one.

Vue.js uses the method of rendering on the streaming-side server. You can render your component and get a readable stream. You can then send this to the HTTP server. It makes the server highly responsive. Your users will get the rendered content very quickly.

Vue.js is very SEO friendly. As the framework supports server-side rendering, the views are rendered directly on the server. The search engines list these.

But the most important thing for you is the ease with which you can learn Vue.js. The structure is elementary. Even new developers will find it easy to use it to build their apps. This framework helps in developing both small and large templates. It helps to save a lot of time.

You can go back and check your errors very easily. You can travel back and inspect all the states apart from testing your components. It is another important feature as far as any developer is concerned.

Vue.js also has very detailed documentation. It helps in writing your applications very quickly. You can build a web page or app with the basic knowledge of HTML or JavaScript.

● Vue.js has pure architecture. It helps in integration with other apps

● Vue.js is lightweight and fast. It can be made lighter by deploying only the interpreter

● You can separate the compiler and the template-to-virtual DOM.

● Due to smooth integration, you can use this to make changes to existing apps

● To make up for any shortfall, you can plug-in any library and makeup.

● As Vue.js uses streaming-side server rendering, your users can get quick responses.

● The server-side rendering also helps in being ranked higher by search engines.

● It has a simple structure. Easy to use for any new developer

● You can go back and check and correct your errors.

● You can check all the existing states.

● Detail documentation also helps build the web page or application very quickly.

Ember.js Decoded

Ember.js is an MVVM model framework. It is open-source software. This platform is mostly used for creating complex multi-page applications. It maintains up-to-date features without discarding any of the old features.

With this framework, you have to follow the architecture of the framework strictly. The JS framework is very tightly organized. It reduces the flexibility that other frameworks might offer.

There is a very refined and developed control system for its platforms and tools. You can integrate it with the new version with the tools provided. There is strict guidance about avoiding outdated APIs.

You can understand Ember’s APIs easily. They are also easy to work. You can make use of highly complex functionalities simply and straightforwardly.

The performance is better as similar jobs are processed together. It creates batches of similar bindings and DOM updates to improve the performance. It means that the browser needs to process them in one go. It will avoid recomputing for each task, wasting a lot of time.

You can write the codes in a simple manner and modules. You can use any of Ember’s APIs. It is possible due to the presence of Promises everywhere.

Ember comes with a well-written guide. The API is recorded in a useful manner. It is a front-end framework that is loaded. Ember has a router, pipeline, services, etc. of its own.

The basis for views, controllers, models, and framework is the Ember Object Model. All components come from the same objects. The framework is firm and steady. The reason is that all elements have similar jobs and characteristics.

Ember has made the general application, organization, and structure clear so that you don’t make any mistakes. You will have no chance to complicate the application unnecessarily. If you have to go out of the defined limits, you will have to force your way out.

The language used for templating in Embers is Handlebars. This language helps Embers to keep its logic out of view. The clean syntax of Handlebars makes it easy for you to read and understand the templates. Handlebar templates are faster to load.

Another advantage you gain from Handlebar is that you don’t have to update your template every time you add or remove data from the page. It will be done automatically by the language itself.

A community that is continually improving the framework supports Ember. They are updating the framework with the latest technology. They also make sure that backward compatibility is possible.

● Ember.js is an open-source MVVM model framework suitable for complex multiple-page applications.

● It offers both the latest and old features.

● It has a very tightly structured framework which doesn’t offer much flexibility

● A very refined control system helps you to integrate with new versions without any problem.

● There is strict guidance about avoiding outdated API versions.

● Ember’s APIs help you to use complex functionalities in a simple manner

● There is no recomputing for each task as the framework allows the browser to do similar functions together.

● Promises allow you to write modular and straightforward code using any API of Ember.js.

● Ember.js is a fully loaded, front-end framework.

● The framework is stable because all components have the same functionalities and properties.

● It has well-defined limitations which will prevent your complicating your application

● Handlebars, the language used by Ember.js allows you to read and understand templates easily. It also helps to load the templates faster.

● Handlebars will ensure to update the template every time you add or remove data.

● Ember.js has an active community that updates the framework regularly and facilitates backward compatibility.

A Comparison Between Ember.js And Vue.js

This article intends to compare the features of both frameworks. Let us see how the characteristics of these frameworks compare. It will help you to make use of the right framework for your web application.

When you need a modern engine for an old application, it is Vue.js which will help you. It combines the best properties of other frameworks. Vue.js is a developing framework. A ready-to-use library of interface elements does not exist. However, many third-party libraries can help you.

Ember.js offers you a well-organized and trustworthy framework. When the development team is big, this is the framework that suits best. It allows everyone to understand the written code and contribute to a common project. The technology will be up-to-date, and the platform will be stable.

Vue.js can help you use the syntax of different kinds. It helps in writing the codes with ease. It is also an SEO friendly framework. Ember is a fully loaded front-end framework and can help you develop the applications very fast. But it is not suitable for developing small projects.

It is not easy to say this is better than that. It will depend on what kind of project you have undertaken. Both have their pluses and minuses. The below table will help in a better comparison.

Final Thoughts

It is not easy to conclude as to which is better. It all depends on the application that you want to develop. Both frameworks are developing. Both are getting updates. Both the communities are working on the frameworks.

While Vue.js is more comfortable for writing codes, Ember is a full-stack framework allowing the development of apps very fast. It is suitable for big projects. It is too complicated to be used for smaller projects.
