GraphQL Queries and Mutations on distinct Parse Versions

GraphQL Queries and Mutations on distinct Parse Versions

As Parse evolves over time, some aspects of it change for better performance, better compatibility and easier development.
One of these aspects is the GraphQL support that evolved from Parse 3.5.0 over time to the latest version available, 3.9.

Here at Back4app, we have three main versions that implement changes in the GraphQL queries and mutations, specifically: 3.7.2, 3.8 and 3.9 and today I will walk you through the differences among those versions, showing what did change and what did not.


Um clone do Instagram usando SwiftUI e GraphQL

Um clone do Instagram usando SwiftUI e GraphQL

Hoje estamos iniciando uma série de postagens no blog que ensinarão você a usar muitas ferramentas interessantes para criar sua própria rede social: um aplicativo que se assemelha ao Instagram.

Não economizaremos tecnologia e usaremos o melhor e o mais recente: Parse, GraphQL, um pouco de NodeJS e especialmente o framework SwiftUI da Apple (ainda a ser lançado). 😍

Isso levará algumas postagens para ser totalmente funcional, mas quando chegarmos lá, você perceberá como pode ser simples colocar suas ideias em funcionamento com muito pouco esforço aqui no Back4App.

Então, parece que é hora de…

Uma breve introdução

Bem, você provavelmente já conhece os enormes benefícios que o Parse traz para o seu processo de desenvolvimento, especialmente se hospedado no Back4App, pois nosso conjunto de ferramentas aumenta a produtividade em grandes quantidades.

E nossas publicações mais recentes sobre o  GraphQL  mostraram como é fácil manter o desenvolvimento de APIs ao longo do tempo, se você o usar. Se você perdeu essas postagens, sugiro fortemente que você reserve um tempo e as leia, pois elas melhorarão muito seu entendimento à medida que avançamos.

Você pode ler mais sobre o GraphQL  aqui  e também temos um post completo sobre como usá-lo  aqui .

Você também pode ver alguma integração com o NodeJS em Cloud Code Functions  aqui .

Isso nos deixa com SwiftUI.

O SwiftUI é, de acordo com a Apple, “uma maneira inovadora e excepcionalmente simples de criar interfaces de usuário em todas as plataformas da Apple com o poder do Swift”.

Eu próprio gosto de pensar que o SwiftUI é mais do que isso.

Se você, como eu, está desenvolvendo software há algum tempo, provavelmente sabe que a comunidade de desenvolvedores sempre esteve dividida entre a conveniência de usar Storyboards, a interface de criação de UI de arrastar e soltar da Apple ou o poder da interface de usuário programática.

O SwiftUI vem para trazer o melhor dos dois mundos: é fácil o suficiente para os iniciantes aprenderem, enquanto mantém a capacidade de manutenção de uma interface do usuário codificada.

Combine isso com a renderização em tempo real, para que os desenvolvedores possam ver facilmente a saída visual do que eles estão codificando, e o façam de duas maneiras. Se você alterar o código, ele refletirá na interface do usuário e alterará graficamente a interface do usuário. no código, e o que você obtém é uma das maneiras mais poderosas e fáceis de fornecer interfaces de usuário com design bonito e manutenção ao longo do tempo.


Instagram Clone App using SwiftUI and GraphQL – HomeView

Instagram Clone App using SwiftUI and GraphQL – HomeView

Today in part 4 of our Instagram clone App with GraphQL we will continue learning some SwiftUI, building our Home view.

In our previous articles, we learned how to sign up a user and how to log in a user and created the Profile view with the respective UIs in our Instagram clone App. Today we will reuse some of that code and create something similar to a UIScrollView with lots of content.

Fast your seat belts and let’s get it going!

For better learning, download the iOS Instagram Clone project with source code.

In our previous post about how to create an Instagram clone app, you learned how to configure everything to have SwiftUI up and running in XCode 11, and created a fully working Sing Up view with GraphQL.

Today we will learn how to create a login view and have the user log out.

We will be needing the project from the previous post, so if you didn’t follow that one, I strongly suggest that you do.

Buckle your seat belts and let’s go!

GraphQL Hosting

GraphQL Hosting

It’s no mystery that every developer wants to make high-quality applications, and if you’re one of them, we are here to assist you in finding a straightforward way to implement and host a GraphQL database. In the past, I’ve been an assiduous REST user, but my concerns about its complexity, over fetching requests and data transfer costs have led me to explore other alternatives.

In addition to some first-tier GraphQL hosting providers such as Back4App, there’s a frequently expanding list of cloud service providers that allow affordable GraphQL hosting.

In this tutorial, I’ll also describe some of the best cloud options to host GraphQL APIs; some providers that are less established but still useful to developers. The tutorial will cover the following hosting options:

  • Parse
  • Back4App
  • Graphcool
  • AWS App Sync
  • Hasura

Creating the next big mobile app is an expensive and time-consuming process. Taking your idea to life demands time and energy, and, financial resources. I will explore how new technologies like GraphQL will reduce your time to market and speed up your app development process.

This article will explain the benefits of using GraphQL together with Backend as a Service platform, and here is a summary of what you will learn:

  • GraphQL overview
  • What is GraphQL?
  • GraphQL Schema
  • GraphQL versus REST
  • Why use GraphQL?
  • Benefits/Downsides of GraphQL
  • When using GraphQL?
  • BaaS and GraphQL working together
  • GraphQL BaaS providers

Today we are starting a series of blog posts that will teach you how to use a lot of cool tools to build your own Social Network: an application that resembles Instagram.

We won’t save up on tech and will be using the latest and greatest: Parse, GraphQL, some NodeJS and especially the (yet to be released) latest Apple’s framework SwiftUI. 😍

This will take a few posts in order to be fully functional, but when we get there, you will realize how simple it can be to get your ideas up and running with very little effort here at Back4app.

For better learning, download the iOS Instagram Clone project with source code.

So, it seems it is time for…

 


GraphQL iOS: Using Cloud Functions in a Swift App

GraphQL iOS: Using Cloud Functions in a Swift App

On this article, I showed you how to use GraphQL with NodeJS Cloud Code in Back4app.

And on this guide, I showed you how to use Apollo GraphQL iOS Client with Swift.

Now let’s bring it all together and make lots of complicated operations by producing really easy code. And let’s also have XCode to automatically generate any API code for us even when we change Classes.

Sounds good? So get some coffee and get along!


GraphQL and NodeJS integrations using Cloud Code Functions

GraphQL and NodeJS integrations using Cloud Code Functions

GraphQL brings sugar, spice, and everything nice to API developers, but it is basically a query language so you can specify what you are looking for.

What if you need more business intelligence than that in your application?

What if you need some logic along with it?

What if you want that neat NPM Module module along with it?

Well, fasten your seat belts because today I’ll show you something very powerful. And with great powers, comes great… well… great time savings, great possibilities, great lots of good stuff…

 


What is GraphQL

What is GraphQL

GraphQL is a query language for APIs developed by Facebook in 2012. In simple words, it’s used to load data from a server to a client (i.e. from an API to your application) much more efficiently than traditional services.

It’s fair to say that GraphQL is unlike anything you might have used before which is precisely why a large number of organizations have switched over to it for building APIs.

In this article, I’ll take a closer look at some of the major problems behind current REST APIs and how GraphQL solves them while improving productivity. I’ll also explain some of the key benefits developers can experience by using GraphQL and whether you should make the switch from REST to GraphQL.

Let’s get started.
