What is Cross-Platform Development?

Cross-platform development refers to the process of creating software applications that can run on multiple operating systems and devices using a single codebase. Instead of developing separate native apps for iOS and Android, cross-platform development allows developers to write code once and deploy it across both platforms (and sometimes even beyond, like the web).

The key advantages of cross-platform development include:

• Cost-effectiveness: One codebase means lower development and maintenance costs.
• Faster time-to-market: Developing once for multiple platforms shortens the development timeline.
• Consistency: Ensures uniformity across platforms, delivering a similar experience to users on different devices.

With these benefits in mind, let’s explore the leading frameworks available for cross-platform development.

In this article, we’ll show you how to start developing an application’s backend with architecture managed by GraphQL. To do this, you should know your way around JavaScript and have some knowledge of the command-line interface. You will also need to have a recent version of Node installed (8 or above).

This tutorial will help you:

• Gain basic knowledge of GraphQL
• Define a GraphQL schema that represents the app’s data structure
• Run an instance of Apollo Server with Express to execute queries that match your schema

Brief introduction 

Nowadays, every software requires a service to obtain data from. This data is usually obtained from an application programming interface or API. After Roy Fielding developed the REST concept in 2000, APIs became one of the cornerstones of programming as they allow for client-server communication. This still remains one of the most popular software development architectures today.

As you may know, the tech industry advances quite rapidly and its community is constantly looking for new technologies and improvements. API management was no exception and, thanks to Facebook, GraphQL was born in 2012.

GraphQL provides a specification of a query language, which means it is neither a piece of software or a package, nor something you can download and use, but a document that explains how this language works and is used. Various companies worked on implementations of GraphQL when it became open source back in 2015. One of them, and the one we’ll look at in this tutorial, is Apollo GraphQL.

What is Apollo Server?

According to Apollo’s official website: 

“Apollo Server is an open-source, spec-compliant GraphQL server that’s compatible with any GraphQL client, including Apollo Client. It’s the best way to build a production-ready, self-documenting GraphQL API that can use data from any source.”

In this particular, we’ll be using Apollo Server as an add-on for our application’s Express middleware.

Let’s jump into the code

You can find a detailed step-by-step guide to get your GraphQL API running using Apollo in Apollo Server’s documentation, but here is an overview of the basics:

1. Creating a project

First of all, you’ll need to create a directory for a new project from your development directory of choice and cd into it using the command line:

Link: script

Then, you’ll start a new Node.js project using npm (or whatever package manager you prefer).

Link: script

Now your project directory contains a package.json file.

2. Installing dependencies

You will need three top-level dependencies for your application to run:

• apollo-server-express: the Express integration that comes with GraphQL Server.
• graphql: the library you’ll use to build a GraphQL schema and execute queries.
• express: in charge of server-side logic for web apps.

In order to install these dependendencies, you will need to run the following command:

Link: script

To make things easier, create an empty index.js file in your project’s root directory which will contain all your code.

3. Defining your GraphQL schema

Every GraphQL server uses a schema in order to define the data structure for clients to query. Here, we’ll see how a server that queries a collection of books by title and author can be created.

We’ll start by opening index.js in your editor of choice and then pasting the following code:

Link: script

The snippet above defines a simple GraphQL schema. This will execute a query named “books”, to which the server will respond with an array of zero or more books.

4. Defining your data set

Once you’ve defined the structure of the data, you’ll create some actual data. Apollo Server can retrieve data from any source you connect to, which includes databases, static object storage services, REST APIs, or even other GraphQL servers. That said, in this example, we’ll hardcode some dummy data to keep things simple. 

You will need to add the following at the end of the index.js file:

Link: script

Keep in mind that each object in the array matches the structure of the Book type defined in our schema.

5. Defining a resolver

Great job so far! Your data set is defined, but Apollo Server is not yet able to use that data set on its own when it’s executing a query. This is why you will need to create a resolver.

Apollo Server uses resolvers to determine to fetch the data associated with a specific type. Since this Book array is hardcoded, the relevant resolver will be quite simple.

You will need to add the following at the end of the index.js file:

Link: script

6. Creating a server with Express JS.

We now have the initial schema with the relevant resolvers. All that’s left is to provide this information to Apollo Server, which can be done using Express middleware.

First, you’ll create an Apollo Server instance that will serve as middleware to an Express HTTP instance using server.applyMiddleware({ app }). Then, add the following at the end of the index.js file. 

Link: script

7. Starting the server

We’re almost done! Now we can run the server and start executing queries. You will need to run the command below from the project’s root directory:

Link: script

This is the output that should appear: Server ready at http://localhost:4000/.

That’s it! You got it!

Final thoughts

Today we learned about Apollo Server and how to define a schema with its corresponding resolvers. We also set up a GraphQL server using Express.js as middleware.

Using Express has a few advantages, one of which is being able to serve both REST and GraphQL at the same time. Also, serving a GraphQL server within Express maintains your ability to use the middleware for common problems like security, authentication and others.

However, we have to say that apollo-server, the standalone GraphQL server, is faster than apollo-server-express.

That said, we believe that, overall, using Express with Apollo Server is a good practice and the tradeoff is more than positive.

Designed by Brendan Eich’s Netscape back in 1995, JavaScript is among the most popular programming languages to date and is used by the majority of developers as of 2020. This is no surprise as it is versatile, easy to learn, and can be used for both frontend and backend development. As you might expect from JavaScript’s popularity, there are many frameworks to choose from when it comes to developing in this language. In this article, we’ll cover some of the most popular JavaScript frontend frameworks.

⦁ React.js

React.js is actually a JavaScript library used to build UI interfaces on the web. It was created by Jordan Walke and a group of Facebook engineers and launched in 2013. It is considered the most influential JavaScript-based web framework as it introduced many new concepts, such as declarative programming and immutable state. It also introduced the Virtual DOM, which improved user experience and performance. In addition to frontend web development, it is often paired with Electron for desktop apps and with Node.js for backend development, and it is also the heart of React Native, a popular framework for mobile app development.
React.js is component-based, declarative and open-source, and has many benefits including outstanding SEO support, one-way data flow, reusable components, easy integration and simple syntax.

This library is used by some of the world’s largest companies, such as Netflix, Twitter and Facebook. React.js is also one of the most popular and loved JavaScript frontend frameworks by developers, as evidenced by Stack Overflow’s 2020 survey and The State of JavaScript. This means it has a large community behind it that is constantly contributing countless learning resources.

⦁ Angular.js

This open-source framework was launched by Google in 2010 and was one of the earliest JavaScript frontend frameworks to hit the market. Back then, Angular.js was far from perfect, so it had to be completely redesigned. This led to a much more successful re-release in 2016.
The framework is used to create single-page web apps and is known for being extremely secure. It should not be confused with Angular: while Angular.js is JavaScript-based and uses directives, Angular is TypeScript and component-based.

Other Angular.js features include DOM sanitization, UI view templates, the fact it’s cross-platform (used for PWAs, native and desktop apps), and the possibility to create accessible applications.
Microsoft, Forbes and, of course, Google, are among the big shots that use it for their websites.

⦁ Vue.js

Vue.js is a more recent frontend JavaScript framework, released in 2014. However, it has managed to make quite an impression: it ranks in third place when it comes to the most loved web frameworks and, according to The State of JavaScript, most developers have either used it and would continue to do so or have heard of it and are interested in using it. It is also one of the few frameworks available that is not backed by a tech giant (it was developed by former Google engineer Evan You). It was conceived as a combination of the best parts of React and Angular.js and has improved on those features.

Vue.js uses Virtual DOM, includes HTML-based templates and offers PWA development as well as two-way data binding. Moreover, the framework is versatile, performant, lightweight and open-source.
Companies such as Apple, Adobe and Nintendo are among those that have adopted this frontend framework.

⦁ Embers.js

Ember.js was created by Apple’s Yehuda Katz in 2011 and launched in 2012. This end-to-end, opinionated and open-source framework is based on the Model—View—ViewModel (MVVM) architecture and supports two-way data binding. It also focuses on convention over configuration and offers a debugging tool called Ember Inspector.

Other features of Ember.js include a data access library called Ember Data, built-in testing and a comprehensive ecosystem with ease of integration for third-party node modules (called Addons)
Although usage of this framework is not that widespread, as of 2019, there was a large number of developers that were interested in using this framework. Some of the companies that support Ember.js include Netflix, Microsoft and LinkedIn.

⦁ Svelte.js

Launched in 2016 by former Guardian developer Rich Harris, Svelte.js is the most recent JavaScript frontend framework in our list. It is open-source, component-based and written in TypeScript. At the time of its launch, Svelte.js was considered revolutionary as it has no virtual DOM: components are built boilerplate-free and then the Svelte Compiler compiles framework-specific code to HTML, CSS and JavaScript and renders it to the browser.

Other features include client and server-side rendering, great SEO support and cross-platform mobile development. It also has a growing community of contributors committed to making the framework grow.
Svelte.js has made a great impression during its short lifespan, ranking in second place when it comes to awareness, interest and satisfaction according to The State of JavaScript. Some of the companies that use Svelte.js include the New York Times and GoDaddy.

Bonus: Meteor

In contrast with the rest of the frameworks in this article, Meteor is actually full-stack, so we’ve added it as a bonus to this list. It was developed in 2012 and based on Node.js. Meteor is not merely a framework but an isomorphic development ecosystem (IDevE). Moreover, it is cross-platform and can be used to create mobile and desktop apps, in addition to web development. When it comes to frontend, it includes its very own template engine and also has integrations for React.js, Vue.js, Angular and Svelte.js, among other frontend networks.
Companies that use Meteor include Ikea, Mazda and Dispatch.

When it comes to developing an app, there are quite a few programming languages and tools to choose from. Developers have long been debating which is the best one, but the truth is, most of the time, it depends on the project you have in mind. In this article, we’ll take a look at Golang advantages (an open-source alternative), and why it might be the right fit for your project. We’ll give you an overview of this technology and go over its most significant features to help you decide whether you should look for Golang development services.

What is Golang?

Golang (or Go) is an open-source, compiled programming language developed in 2009 by Google with the help of many community collaborators. Golang has had many releases since then and is currently on version 1.15.2. In addition to Google, other big companies that use this coding language include Apple and Facebook.

The language came to be as an alternative to Java and C++ for app developers, providing a consistent language with a focus on code readability and clear documentation, among many other features. Golang is known for its simplicity, reliability and efficient code compilation when it comes to developing software.

Golang advantages:

1. Minimalist and easy to learn

Golang’s specification is merely 50 pages long (Java’s, for example, is 750 pages long) and it’s full of examples. The language is quite easy to read and easy to learn from just this specification (and even more so if you are already well-versed in Java or C). Moreover, its clean syntax means the language is also easy to maintain. Some of the features that make Go so simple include a minimal interface, no implicit conversions, and packages with clear code separation.

2. Fast

The fact that Go is a compiled language means the code you write is directly translated into the relevant format for the processor instead of compiling into byte-code first like other languages do. With no middle-man, Golang is not only faster but also more reliable.

3. Transparent

Go’s syntax is meant to be transparent. It has only one standard code format created automatically by the fmt tool. The language makes it easy for you to always know what your code is doing and estimate resources. Languages like Python are as readable as Go, but not quite as transparent.

4. Large community = Extensive tools

As with most popular programming languages, Golang has a large and supportive community. The language has its own GitHub repository, which includes a number of editors and plugins, and there are also many other resources available, including a Slack channel, a blog, a sub-Reddit and a forum. And if that isn’t enough, there are countless Golang programmers out there open to share their knowledge.

5. Large talent pool

The fact Golang has such a large community also means there are countless developers offering Golang development services. As the most in-demand language in the world, you are sure to have your pick of developers if you’re looking to start a project using Go.

6. Always compatible

Golang offers excellent backward compatibility so, if you develop an app with its current version, you should not have problems with new versions in the future. Go’s compatibility means switching versions of the language at any time should be hassle-free.

7. Scalable

Golang’s advantages includes Goroutines—functions that run simultaneously and independently—, which take little memory space and make it scalable when dealing with several concurrent processes. You can actually run millions of Goroutines without crashing your system, making for a leaner software.

8. Built-in testing

Go includes a built-in testing tool, which, just like everything else regarding this language, was created with simplicity and efficiency in mind. It can be used for various types of testing and profiling, and you can even run tests in parallel, among many other features.

Final thoughts on Golang advantages

As you can see, Go has many perks that make pursuing Golang development services very appealing. If you want more information, you can look at Go’s website to find extensive documentation and tutorials.
