Instalar Bootstrap 4 + Sass en Vue

En este tutorial rápido aprenderemos como instalar Bootstrap y utilizar la linea de comandos de Vue para habilitar el soporte Sass para aprovechar al máximo la configuración del framework. Unicamente vamos a utilizar los estilos de Bootstrap, no tocaremos temas como jQuery o librerías externas.

Comencemos instalando la linea de comandos de vue:

npm install -g @vue/cli

En caso de que ya tuvieras instalada en tu equipo la linea de comandos (muy bien por ti! 👏) te recomiendo que la reinstales para asegurarte que usas la versión mas reciente, en este ejemplo usaremos la versión 3.6.2, puedes encontrar la versión que usa tu ordenador con el comando:

vue --version

El siguiente paso es crear un nuevo proyecto Vue con el comando

vue create vue-bootstrap

Pero en este caso, en vez de usar la configuración por defecto, usaremos la opción manual para habilitar Sass, si no sabes como hacerlo, mira las opciones que debes elegir en la terminal:

Al finalizar el proceso, la linea de comandos de Vue ha configurado el soporte para Sass, a partir de ahora, se compilará y agregará al proyecto automáticamente.

Ahora vamos a instalar Bootstrap en este proyecto, para eso tenemos que ejecutar:

npm install bootstrap --save

Después de terminar la instalación tienes que buscar el punto de entrada de la aplicación, que en este caso seria el archivo App.vue, busca la sección style del documento e importa los estilos de Bootstrap asi:

<style lang="scss">
@import '../node_modules/bootstrap/scss/bootstrap.scss';
</style>

Si te fijas bien en esta etiqueta, estamos usando el atributo lang=”scss” para informarle al compilador de Vue que esa sección debe ser interpretada bajo la sintaxis de Sass, recuerda incluirla en todos tus componentes.

La mejor parte de usar Sass, ( ademas de que tienes un CSS optimizado gracias a la compilación) es que puedes aprovechar elementos extra como por ejemplo el concepto de variables!

Supongamos que quieres adaptar algunos colores para que se ajusten a la paleta cromática de tu cliente, puedes crear una subcarpeta llamada “styles” dentro de la carpeta “src” de tu proyecto y alli incluir un archivo con el nombre “custom.scss”.

En este archivo vamos a reescribir los valores variables de color y tipografías que usa bootstrap y gracias a que estamos compilando el CSS con Sass, estos valores se actualizarán en todo el documento

// importa tipografía desde google fonts
@import url("https://fonts.googleapis.com/css?family=PT+Sans");

// asigna la tipografía por defecto
$font-family-sans-serif: "PT Sans", sans-serif;

// modifica los colores por defecto
$green: #41b883;
$red: #ce679b;
$blue: #7952b3;

Y para que estos cambios sean visibles en la aplicación, tienes que importar el documento en en la sección style de app.vue

<style lang="scss">
   @import "./styles/custom.scss";
   @import "../node_modules/bootstrap/scss/bootstrap.scss";
</style>

Si quieres aprender más sobre las variables de configuración de Bootstrap, puedes darle una ojeada a la documentación

En este momento ya tienes Bootstrap con soporte Sass en tu aplicación, pero para poder apreciar los cambios, vamos a modificar el archivo App.vue para que su plantilla tenga un HTML con las clases que acabamos de importar, el resultado final del archivo debería ser este:

<template>
  <div id="app" class="container">
    <main role="main">
      <div class="jumbotron">
        <div class="container">
          <h1 class="display-3">Bootstrap + Vue + Sass</h1>
          <p>
            <a
              class="btn btn-success btn-lg"
              href="http://vuejs.org"
              role="button"
            >Documentación Vue</a>
          </p>
          <p>
            <a
              class="btn btn-danger btn-lg"
              href="https://sass-lang.com"
              role="button"
            >Documentación Sass</a>
          </p>
          <p>
            <a
              class="btn btn-primary btn-lg"
              href="https://getbootstrap.com"
              role="button"
            >Documentación Bootstrap</a>
          </p>
        </div>
      </div>

      <div class="container">
        <div class="row">
          <div class="col-md-4">
            <h2>Sección 1</h2>
            <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
            <p>
              <a class="btn btn-secondary" href="#" role="button">Botón »</a>
            </p>
          </div>
          <div class="col-md-4">
            <h2>Sección 2</h2>
            <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
            <p>
              <a class="btn btn-secondary" href="#" role="button">Botón »</a>
            </p>
          </div>
          <div class="col-md-4">
            <h2>Sección 3</h2>
            <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
            <p>
              <a class="btn btn-secondary" href="#" role="button">Botón »</a>
            </p>
          </div>
        </div>

        <hr>
      </div>
    </main>
  </div>
</template>

<script>
export default {
  name: "app",
  components: {}
};
</script>

<style lang="scss">
@import "./styles/custom.scss";
@import "../node_modules/bootstrap/scss/bootstrap.scss";
</style>

App.vue

Ahora, solo tienes que activar el servidor local de vue para ver el resultado usando

npm run serve

Si todo sale bien deberías ver este documento, con un layout responsivo basado en Bootstrap 4, si notas los colores de los botones, están usando la configuración personalizada y ahora se ajustan a la paleta oficial de cada framework usado

Si tienes algún problema para hacer funcionar tu proyecto, puedes usar como base este repositorio de github donde puse los archivos que usamos como ejemplo.

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.
