Welcome to our guide on building a toilet management application using React Native and Express! This user-friendly tutorial will walk you through the necessary steps to set up your project, install dependencies, and troubleshoot common issues. So grab your coding tools and let’s get started!

Step 1: Set Up Your React Native Environment

The first step in developing your app is to clone the React Native project repository and install the necessary dependencies.

• Clone the Repository: Open your terminal and run the following command:

git clone https://github.com/liumingmusic/react-native_toiletApp.git

• Change Directory: Move into your project directory with:

cd toilet

• Install Dependencies: Then, install the dependencies and run your application:

npm install

• Run the Application: For iOS, execute:

react-native run-ios

• For Android, just replace iOS with Android in the command above.

Step 2: Setting Up the Express Server

Next, let’s set up an Express server to handle backend requests.

• Install Node.js and npm: Ensure Node.js is installed by checking Node.js Official Site.
• Install cnpm: To install `cnpm` (a faster npm mirror), run:

npm install -g cnpm --registry=https://registry.npm.taobao.org

• Install Express Generator: Install the Express generator globally:

npm install -g express-generator

• Create a New Express App: Generate an app called toiletApp:

express -e service-eejs

• Install App Dependencies: Navigate to your app directory and install its dependencies:

cd toiletApp && cnpm install

• Start the Server: Run the server with:

npm start

• Your Express server will now be running at localhost:3000.

Step 3: Directory Structure Breakdown

Here’s a glimpse of the directory structure of your Express app to help you understand where everything fits:

• bin/: Contains the startup script.
• node_modules/: Contains all the installed packages.
• public/: Contains static files like CSS and JavaScript.
• routes/: This folder will hold route definitions.
• views/: Contains EJS templates for rendering dynamic responses.

Step 4: Adding Functionalities

From here, you can start adding functionalities to your app such as CRUD operations. Think of it like adding different tools to a toolbox; each tool has its purpose whether it is to create, read, update, or delete data.

Step 5: Troubleshooting Common Issues

As you embark on your coding adventure, you may encounter a few bumps along the way. Here’s how to resolve some of the common issues:

• Issue: Your app doesn’t start.

  – Ensure that the necessary dependencies are properly installed.

• Issue: Errors during npm install.

  – Try running cnpm install instead of npm install for faster results.

• Issue: Can’t connect to localhost.

  – Double-check the URL in your browser. It should be localhost:3000.
