How to Build Simple Tetris Game in JavaScript React with Typescript

Build Tetris in Javascript React with Typescript. This is version 2 of my popular course where I added in Typescript and optimized some stuff.

This tutorial is considered advanced React so therefore I recommend having basic knowledge in Javascript and React.

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.

JavaScript Snake Game Tutorial - Develop a Simple Snake Game

Work on real-time JavaScript Snake game project and become a pro

Snake game is an interesting JavaScript project for beginners. Snake game is a single-player game, which we’ve been playing for a very long time. The game mainly consists of two components – snake and fruit. And we just need to take our snake to the food so that it can eat and grow faster and as the number of fruits eaten increases, the length of snake increases which makes the game more interesting. While moving if the snake eats its own body, then the snake dies and the game ends. Now let’s see how we can create this.

JavaScript Project Prerequisites

To implement the snake game in JavaScript you should have basic knowledge of:

1. Basic concepts of JavaScript

2. HTML

3. CSS

Download Project Code

Before proceeding ahead please download source code of Snake Game: Snake Game in JavaScript

Steps to Build the Project – JavaScript Snake game

1. Create Html file

HTML builds the basic structure. This file contains some basic HTML tags like div, h1, title, etc. also we’ve used bootstrap (CDN is already included).

index.html:

Code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>DataFlair Snake game</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">
    <link rel="stylesheet" href="static/style.css">
</head>
<body>
    <div class="container">
        <div class ="Jumbotron">
        <h1>DataFlair Snake game using vanilla JavaScript</h1>

            <h2 class="btn btn-info"> 
                Score:   0 
            </h2>

            <div class="containerCanvas">
                <canvas id="canvas" width="500" height="500" class="canvasmain"> </canvas>
            </div>
        </div>
    </div>
    <script src="static/fruit.js"></script>
    <script src="static/snake.js"></script>
    <script src="static/draw.js"></script>
</body>
</html>

We have used simple HTML tags except tag. This new tag was introduced in HTML5, which is used to draw graphics, via JavaScript. It is nothing without JavaScript so we will use it in our JavaScript file to actually draw the board and the objects required. We’ll see its implementation in JS files.

How to Build Simple Tetris Game with React & TypeScript

Playing games is fun. What’s better, and also more beneficial, is creating your own games. Why? It is a great way to learn new skills, or get better. In this tutorial, you will learn how to write your own Tetris game with React, JavaScript and TypeScript. Have fun and work on your programming skills at the same time!

Project setup

The first step is putting setting up the files you need for our Tetris game. You can do this quickly with the help of create-react-app package. This package can generate starting template for us. There are two ways to get this done. You can install the package globally on your computer, with your favorite dependency manager. This is the first way.

The second way is using it via npx. You don’t have to install any package if you want to use it. Not even if you want to use it more often. If you have stable internet connection, you can use npx. It will temporarily download the package, let you use it, and then delete it. It is almost like using npm except that you don’t bloat your disk.

One thing before you proceed to generating the template. This tutorial will use TypeScript. This means that you have to include --typescript flag when you use create-react-app. So, if you prefer the first way, use npm create-react-app react-tetris-ts --typescript or yarn create-react-app react-tetris-ts --typescript.

If you want to use npx just replace npm, or yarn, with npm. The rest will be the same: npx create-react-app react-tetris-ts --typescript. After npm, yarn or npx do its job, you are ready to start building our Tetris game. You don’t need to add any other dependencies, unless you want to. If so, go ahead. Otherwise, you are good to go.

// package.json

{
  "name": "react-tetris-ts",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "dependencies": {
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-scripts": "3.0.1",
    "typescript": "3.5.1"
  },
  "devDependencies": {
    "@types/jest": "24.0.13",
    "@types/node": "12.0.7",
    "@types/react": "16.8.19",
    "@types/react-dom": "16.8.4"
  }
}

When you are done, this will be the structure for this project:

react-tetris-ts/
├─node_modules
├─public
│ ├─favicon.ico
│ ├─index.html
│ └─manifest.json
├─src
│ ├─components
│ │ └─tetris-board.tsx
│ │ └─tetris.tsx
│ ├─styles
│ │ └─styles.css
│ ├─index.tsx
│ └─react-app-env.d.ts
│ └─serviceWorker.ts
└─ package.json
└─ tsconfig.json

Side note: If you want to prevent webpack from automatically opening the browser every time you start the project, do the following. In the root of your project, create _.env.development_ file. Inside this file, add _BROWSER=none_ and save it. From now on, webpack will no longer open the browser when you launch the _start_ npm script.
