Tutorial: Build a Node and React App - Visual Studio

Visual Studio allows you to easily create a Node.js project and experience IntelliSense and other built-in features that support Node.js. In this tutorial for Visual Studio, you create a Node.js web application project from a Visual Studio template. Then, you create a simple app using React.

In this tutorial, you learn how to:

  • Create a Node.js project
  • Add npm packages
  • Add React code to your app
  • Transpile JSX
  • Attach the debugger

Before you begin

Here’s a quick FAQ to introduce you to some key concepts.

What is Node.js?

Node.js is a server-side JavaScript runtime environment that executes JavaScript server-side.

What is npm?

npm is the default package manager for the Node.js. The package manager makes it easier for programmers to publish and share source code of Node.js libraries and is designed to simplify installation, updating, and uninstallation of libraries.

What is React?

React is a front-end framework to create a UI.

What is JSX?

JSX is a JavaScript syntax extension, typically used with React to describe UI elements. JSX code must be transpiled to plain JavaScript before it can run in a browser.

What is webpack?

webpack bundles JavaScript files so they can run in a browser. It can also transform or package other resources and assets. It is often used to specify a compiler, such as Babel or TypeScript, to transpile JSX or TypeScript code to plain JavaScript.

Prerequisites

  • You must have Visual Studio installed and the Node.js development workload.

    If you haven’t already installed Visual Studio 2019

    If you need to install the workload but already have Visual Studio, go to Tools > Get Tools and Features…, which opens the Visual Studio Installer. Choose the Node.js development workload, then choose Modify.

    Node.js workload in VS Installer

  • You must have the Node.js runtime installed.

    This tutorial was tested with version 10.16.0.

    If you don’t have it installed, install the LTS version from the Node.js website. In general, Visual Studio automatically detects the installed Node.js runtime. If it does not detect an installed runtime, you can configure your project to reference the installed runtime in the properties page (after you create a project, right-click the project node and choose Properties).

Create a project

First, create a Node.js web application project.

  1. Open Visual Studio.

  2. Create a new project.

    Press Esc to close the start window. Type Ctrl + Q to open the search box, type Node.js, then choose Blank Node.js Web Application - JavaScript. (Although this tutorial uses the TypeScript compiler, the steps require that you start with the JavaScript template.)

    In the dialog box that appears, choose Create.

    From the top menu bar, choose File > New > Project. In the left pane of the New Project dialog box, expand JavaScript, then choose Node.js. In the middle pane, choose Blank Node.js Web Application, type the name NodejsWebAppBlank, then choose OK.

    If you don’t see the Blank Node.js Web Application project template, you must add the Node.js development workload. For detailed instructions.

    Visual Studio creates the new solution and opens your project.

    Node.js project in Solution Explorer

    (1) Highlighted in bold is your project, using the name you gave in the New Project dialog box. In the file system, this project is represented by a .njsproj file in your project folder. You can set properties and environment variables associated with the project by right-clicking the project and choosing Properties. You can do round-tripping with other development tools, because the project file does not make custom changes to the Node.js project source.

    (2) At the top level is a solution, which by default has the same name as your project. A solution, represented by a .sln file on disk, is a container for one or more related projects.

    (3) The npm node shows any installed npm packages. You can right-click the npm node to search for and install npm packages using a dialog box or install and update packages using the settings in package.json and right-click options in the npm node.

    (4) package.json is a file used by npm to manage package dependencies and package versions for locally-installed packages.

    (5) Project files such as server.js show up under the project node. server.js is the project startup file and that is why it shows up in bold. You can set the startup file by right-clicking a file in the project and selecting Set as Node.js startup file.

Add npm packages

This app requires a number of npm modules to run correctly.

  • react
  • react-dom
  • express
  • path
  • ts-loader
  • typescript
  • webpack
  • webpack-cli
  1. In Solution Explorer (right pane), right-click the npm node in the project and choose Install New npm Packages.

    In the Install New npm Packages dialog box, you can choose to install the most current package version or specify a version. If you choose to install the current version of these packages, but run into unexpected errors later, you may need to install the exact package versions described later in these steps.

  2. In the Install New npm Packages dialog box, search for the react package, and select Install Package to install it.

    Install npm packages

    Select the Output window to see progress on installing the package (select Npm in the Show output from field). When installed, the package appears under the npm node.

    The project’s package.json file is updated with the new package information including the package version.

  3. Instead of using the UI to search for and add the rest of the packages one at a time, paste the following code into package.json. To do this, add a dependencies section with this code:

    "dependencies": {
      "express": "~4.16.4",
      "path": "~0.12.7",
      "react": "~16.6.0",
      "react-dom": "~16.6.0",
      "ts-loader": "~5.3.0",
      "typescript": "~3.1.5",
      "webpack": "~4.23.1",
      "webpack-cli": "~3.1.2"
    }
    
    

    If there is already a dependencies section in your version of the blank template, just replace it with the preceding JSON code.

  4. Save the changes.

  5. Right-click npm node in your project and choose Update npm Packages.

    In the lower pane, select the Output window to see progress on installing the packages. Installation may take a few minutes and you may not see results immediately. To see the output, make sure that you select Npm in the Show output from field in the Output window.

    Here are the npm modules as they appear in Solution Explorer after they are installed.

    npm packages

If you prefer to install npm packages using the command line, right-click the project node and choose **Open Command Prompt Here**. Use standard Node.js commands to install packages.

Add project files

In these steps, you add four new files to your project.

  • app.tsx
  • webpack-config.js
  • index.html
  • tsconfig.json

For this simple app, you add the new project files in the project root. (In most apps, you typically add the files to subfolders and adjust relative path references accordingly.)

  1. In Solution Explorer, right-click the project NodejsWebAppBlank and choose Add > New Item.

  2. In the Add New Item dialog box, choose TypeScript JSX file, type the name app.tsx, and select Add or OK.

  3. Repeat these steps to add webpack-config.js. Instead of a TypeScript JSX file, choose JavaScript file.

  4. Repeat the same steps to add index.html to the project. Instead of a JavaScript file, choose HTML file.

  5. Repeat the same steps to add tsconfig.json to the project. Instead of a JavaScript file, choose TypeScript JSON Configuration file.

Add app code

  1. Open server.js and replace the existing code with the following code:

    'use strict';
    var path = require('path');
    var express = require('express');
    
    var app = express();
    
    var staticPath = path.join(__dirname, '/');
    app.use(express.static(staticPath));
    
    // Allows you to set port in the project properties.
    app.set('port', process.env.PORT || 3000);
    
    var server = app.listen(app.get('port'), function() {
        console.log('listening');
    });
    
    

    The preceding code uses Express to start Node.js as your web application server. This code sets the port to the port number configured in the project properties (by default, the port is configured to 1337 in the properties). To open the project properties, right-click the project in Solution Explorer and choose Properties.

  2. Open app.tsx and add the following code:

    declare var require: any
    
    var React = require('react');
    var ReactDOM = require('react-dom');
    
    export class Hello extends React.Component {
        render() {
            return (
                <h1>Welcome to React!!</h1>
            );
        }
    }
    
    ReactDOM.render(<Hello />, document.getElementById('root'));
    
    

    The preceding code uses JSX syntax and React to display a simple message.

  3. Open index.html and replace the body section with the following code:

    <body>
        <div id="root"></div>
        <!-- scripts -->
        <script src="./dist/app-bundle.js"></script>
    </body>
    
    

    This HTML page loads app-bundle.js, which contains the JSX and React code transpiled to plain JavaScript. Currently, app-bundle.js is an empty file. In the next section, you configure options to transpile the code.

Configure webpack and TypeScript compiler options

In the previous steps, you added webpack-config.js to the project. Next, you add webpack configuration code. You will add a simple webpack configuration that specifies an input file (app.tsx) and an output file (app-bundle.js) for bundling and transpiling JSX to plain JavaScript. For transpiling, you also configure some TypeScript compiler options. This code is a basic configuration that is intended as an introduction to webpack and the TypeScript compiler.

  1. In Solution Explorer, open webpack-config.js and add the following code.

    module.exports = {
        devtool: 'source-map',
        entry: "./app.tsx",
        mode: "development",
        output: {
            filename: "./app-bundle.js"
        },
        resolve: {
            extensions: ['.Webpack.js', '.web.js', '.ts', '.js', '.jsx', '.tsx']
        },
        module: {
            rules: [
                {
                    test: /\.tsx$/,
                    exclude: /(node_modules|bower_components)/,
                    use: {
                        loader: 'ts-loader'
                    }
                }
            ]
        }
    }
    
    

    The webpack configuration code instructs webpack to use the TypeScript loader to transpile the JSX.

  2. Open tsconfig.json and replace the default code with the following code, which specifies the TypeScript compiler options:

    {
      "compilerOptions": {
        "noImplicitAny": false,
        "module": "commonjs",
        "noEmitOnError": true,
        "removeComments": false,
        "sourceMap": true,
        "target": "es5",
        "jsx": "react"
      },
      "exclude": [
        "node_modules"
      ],
      "files": [
        "app.tsx"
      ]
    }
    
    

    app.tsx is specified as the source file.

Transpile the JSX

  1. In Solution Explorer, right-click the project node and choose Open Command Prompt Here.

  2. In the command prompt, type the following command:

    node_modules\.bin\webpack app.tsx --config webpack-config.js

    The command prompt window shows the result.

    Run webpack

    If you see any errors instead of the preceding output, you must resolve them before your app will work. If your npm package versions are different than the versions shown in this tutorial, that can be a source of errors. One way to fix errors is to use the exact versions shown in the earlier steps. Also, if one or more of these package versions has been deprecated and results in an error, you may need to install a more recent version to fix errors.

  3. In Solution Explorer, right-click the project node and choose Add > Existing Folder, then choose the dist folder and choose Select Folder.

    Visual Studio adds the dist folder to the project, which contains app-bundle.js and app-bundle.js.map.

  4. Open app-bundle.js to see the transpiled JavaScript code.

  5. If prompted to reload externally modified files, select Yes to All.

    Load modified files

Each time you make changes to app.tsx, you must rerun the webpack command. To automate this step, add a build script to transpile the JSX.

Add a build script to transpile the JSX

Starting in Visual Studio 2019, a build script is required. Instead of transpiling JSX at the command line (as shown in the preceding section), you can transpile JSX when building from Visual Studio.

  • Open package.json and add the following section after the dependencies section:

    "scripts": {
      "build": "webpack-cli app.tsx --config webpack-config.js"
    }
    
    

Run the app

  1. Select either Microsoft Edge or Chrome as the current debug target.

    Select Chrome as debug target

    If Chrome is available on your machine, but does not show up as an option, choose Web Browser (browsername) > Select Web Browser from the debug target dropdown list, and select Chrome as the default browser target.

  2. To run the app, press F5 (Debug > Start Debugging) or the green arrow button.

    A Node.js console window opens that shows the port on which the debugger is listening.

    Visual Studio starts the app by launching the startup file, server.js.

    Run React in browser

  3. Close the browser window.

  4. Close the console window.

Set a breakpoint and run the app

  1. In server.js, click in the gutter to the left of the staticPath declaration to set a breakpoint:

    Set a breakpoint

    Breakpoints are the most basic and essential feature of reliable debugging. A breakpoint indicates where Visual Studio should suspend your running code so you can take a look at the values of variables, or the behavior of memory, or whether or not a branch of code is getting run.

  2. To run the app, press F5 (Debug > Start Debugging).

    The debugger pauses at the breakpoint you set (the current statement is marked in yellow). Now, you can inspect your app state by hovering over variables that are currently in scope, using debugger windows like the Locals and Watch windows.

  3. Press F5 to continue the app.

  4. If you want to use the Chrome Developer Tools or F12 Tools for Microsoft Edge, press F12. You can use these tools to examine the DOM and interact with the app using the JavaScript Console.

  5. Close the web browser and the console.

Set and hit a breakpoint in the client-side React code

In the preceding section, you attached the debugger to server-side Node.js code. To attach the debugger from Visual Studio and hit breakpoints in client-side React code, the debugger needs help to identify the correct process. Here is one way to enable this.

Prepare the browser for debugging

For this scenario, use either Microsoft Edge (Chromium), currently named Microsoft Edge Beta in the IDE, or Chrome.

For this scenario, use Chrome.

  1. Close all windows for the target browser.

    Other browser instances can prevent the browser from opening with debugging enabled. (Browser extensions may be running and preventing full debug mode, so you may need to open Task Manager to find unexpected instances of Chrome.)

    For Microsoft Edge (Chromium), also shut down all instances of Chrome. Because both browsers share the chromium code base, this gives the best results.

  2. Start your browser with debugging enabled.

    Starting in Visual Studio 2019, you can set the --remote-debugging-port=9222 flag at browser launch by selecting Browse With… > from the Debug toolbar, then choosing Add, and then setting the flag in the Arguments field. Use a different friendly name for the browser such as Edge with Debugging or Chrome with Debugging.

    Set your browser to open with debugging enabled

    Alternatively, open the Run command from the Windows Start button (right-click and choose Run), and enter the following command:

    msedge --remote-debugging-port=9222

    or,

    chrome.exe --remote-debugging-port=9222

    Open the Run command from the Windows Start button (right-click and choose Run), and enter the following command:

    chrome.exe --remote-debugging-port=9222

    This starts your browser with debugging enabled.

    The app is not yet running, so you get an empty browser page.

Attach the debugger to client-side script

  1. Switch to Visual Studio and then set a breakpoint in your source code, either app-bundle.js or app.tsx.

    For app-bundle.js, set the breakpoint in the render() function as shown in the following illustration:

    Set a breakpoint

    To find the render() function in the transpiled app-bundle.js file, use Ctrl+F (Edit > Find and Replace > Quick Find).

    For app.tsx, set the breakpoint inside the render() function, on the return statement.

    Set a breakpoint

  2. If you are setting the breakpoint in the .tsx file (rather than app-bundle.js), you need to update webpack-config.js. Replace the following code:

    output: {
        filename: "./app-bundle.js",
    },
    
    

    with this code:

    output: {
        filename: "./app-bundle.js",
        devtoolModuleFilenameTemplate: '[resource-path]'  // removes the webpack:/// prefix
    },
    
    

    This is a development-only setting to enable debugging in Visual Studio. This setting allows you to override the generated references in the source map file, app-bundle.js.map, when building the app. By default, webpack references in the source map file include the webpack:/// prefix, which prevents Visual Studio from finding the source file, app.tsx. Specifically, when you make this change, the reference to the source file, app.tsx, gets changed from webpack:///./app.tsx to ./app.tsx, which enables debugging.

  3. Select your target browser as the debug target in Visual Studio, then press Ctrl+F5 (Debug > Start Without Debugging) to run the app in the browser.

    If you created a browser configuration with a friendly name, choose that as your debug target.

    The app opens in a new browser tab.

  4. Choose Debug > Attach to Process.

Starting in Visual Studio 2017, once you attach to the process the first time by following these steps, you can quickly reattach to the same process by choosing **Debug** > **Reattach to Process**.
  1. In the Attach to Process dialog box, get a filtered list of browser instances that you can attach to.

    In Visual Studio 2019, choose the correct debugger for your target browser, JavaScript (Chrome) or JavaScript (Microsoft Edge - Chromium) in the Attach to field, type chrome or edge in the filter box to filter the search results.

    In Visual Studio 2017, choose Webkit code in the Attach to field, type chrome in the filter box to filter the search results.

  2. Select the browser process with the correct host port (localhost in this example), and select Attach.

    The port (1337) may also appear in the Title field to help you select the correct browser instance.

    The following example shows how this looks for the Microsoft Edge (Chromium) browser.

    Attach to process

    You know the debugger has attached correctly when the DOM Explorer and the JavaScript Console open in Visual Studio. These debugging tools are similar to Chrome Developer Tools and F12 Tools for Microsoft Edge.

If the debugger does not attach and you see the message "Unable to attach to the process. An operation is not legal in the current state.", use the Task Manager to close all instances of the target browser before starting the browser in debugging mode. Browser extensions may be running and preventing full debug mode.
  1. Because the code with the breakpoint already executed, refresh your browser page to hit the breakpoint.

    While paused in the debugger, you can examine your app state by hovering over variables and using debugger windows. You can advance the debugger by stepping through code (F5, F10, and F11). For more information on basic debugging features, see First look at the debugger.

    You may hit the breakpoint in either app-bundle.js or its mapped location in app.tsx, depending on which steps you followed previously, along with your environment and browser state. Either way, you can step through code and examine variables.

    • If you need to break into code in app.tsx and are unable to do it, use Attach to Process as described in the previous steps to attach the debugger. Make sure you that your environment is set up correctly:

      • You closed all browser instances, including Chrome extensions (using the Task Manager), so that you can run the browser in debug mode. Make sure you start the browser in debug mode.

      • Make sure that your source map file includes a reference to ./app.tsx and not webpack:///./app.tsx, which prevents the Visual Studio debugger from locating app.tsx. Alternatively, if you need to break into code in app.tsx and are unable to do it, try using the debugger; statement in app.tsx, or set breakpoints in the Chrome Developer Tools (or F12 Tools for Microsoft Edge) instead.

    • If you need to break into code in app-bundle.js and are unable to do it, remove the source map file, app-bundle.js.map.

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.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:
