Building CRUD in ag-Grid with GraphQL & React

This post illustrates how to perform CRUD operations using ag-Grid server-side row model and JSON-server, GraphQL, Apollo-client and React/TypeScript. We’ve built an example to demonstrate how to implement the necessary operations to have a fully-functional ag-Grid in this scenario. I hope this helps you effectively use ag-Grid with GraphQL and React!

Live sample

You can download the project from GitHub and easily reuse its code to implement this in your project. Please see a quick demo of the sample below showing the CRUD operations:

Architecture

Let’s go over the components/frameworks and their roles in this:

  • JSON-server: Provides a full fake REST API that we’ll use to create, read, update and delete records
  • GraphQL: Allows requesting the exact data we need from our server
  • Apollo-client: Allows building queries directly from the front-end
  • React/TypeScript: Used to bootstrap a single-page React application using create-react-app

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Next-level cell editing in ag-Grid with CRUD and React Hooks

Custom Editors

ag-Grid provides a number of out of the box editors that will fulfill most simple use cases. However, In the case that you would like to extend the behaviour of an editor, ag-Grid allows you to create your own Custom Editors:

Simple Editor

See component code

The SimpleEditor component is applied to the Athlete column.

This SimpleEditor component shows the bare bones configuration needed for a custom editor written using React Hooks.

// src/Components/Editors/SimpleEditor.jsx

export default forwardRef((props, ref) => {
    const inputRef = useRef();
    const [value, setValue] = useState('');

    function inputHandler(e) {
        setValue(e.target.value);
    }

    useImperativeHandle(ref, () => {
        return {
            getValue: () => {
                return value;
            },
            afterGuiAttached: () => {
                setValue(props.value);
                inputRef.current.focus();
                inputRef.current.select();
            }
        };
    });

    return (
        <input
            type="text"
            className="ag-input-field-input ag-text-field-input"
            ref={inputRef}
            onChange={inputHandler}
            value={value}
            placeholder={'Enter ' + props.column.colId}
        />
    )
})

The result of editing is returned to ag-Grid in the getValue(required) lifecycle method. We’ve also included the afterGuiAttached(optional)hook where we focus on and highlight the component after it has mounted.

It’s important to note that when using React Hooks that all custom editors should be wrapped in React.forwardRef and all ag-Grid lifecycle methods should be returned in React.useImperativeHandle.

Asynchronous Validation

See component code

The AsyncValidation component is applied to the Sports column.

This component demonstrates how asynchronous validation can be configured inside a custom editor.

We’ve mocked a server call using a Promise that gets resolved after a user has finished typing and updates the component’s valid state variable:

// src/Components/Editors/AsyncValidationEditor.jsx

export default forwardRef((props, ref) => {
// [...]

const debouncedInputVal = useDebounce(inputValue, 1000);

    function inputHandler(e) {
        setTouched(true);
        setInputValue(e.target.value);
        setValidating(true);
    }

    useEffect(() => {
        // random time between 0 and 1000ms
        let timeout = Math.floor(Math.random() * 1000);

        new Promise((resolve, reject) => {
            if (inputValue === '') {
                resolve(false);
            } else {
                setTimeout(() => {
                    resolve(props.condition(inputValue));
                }, timeout);
            }
        })
            .then(valid => {
                setValid(valid);
                setValidating(false)
            })
            .catch(err => console.log(err));
    }, [debouncedInputVal]);

    // [...]
    })

The valid state variable then dictates whether or not the editor’s updated value will be returned to the grid in the isCancelAfterEnd(optional) lifecycle hook:

// src/Components/Editors/AsyncValidationEditor.jsx

useImperativeHandle(ref, () => {
        return {
            // [...]
            isCancelAfterEnd: () => {
                return !valid || validating;
            },
        };
    });

Build a simple React Native Pokemon app with React-Navigation

As we start learning new technologies we want to start building something or work on a simple project to get a better understanding of the technology. So, let’s build this simple app.
For this app, we will be using PokeApi to get our pokemon data, and also we will be using Hooks. I am using pokemondb for pokemon sprites. It’s just a personal preference you can use whatever you want.

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

  • React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
  • React.js and React Native have similar syntax and workflows, but their implementation is quite different.
  • React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
  • React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

  • United States- $120,000
  • Canada - $110,000
  • United Kingdom - $71,820
  • The Netherlands $49,095
  • Spain - $35,423.00
  • France - $44,284
  • Ukraine - $28,990
  • India - $9,843
  • Sweden - $55,173
  • Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

  • Conduct thorough candidate research, including portfolios and areas of expertise.
  • Before you sit down with your interviewing panel, do some homework.
  • Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
