How to Execute Your Updated start Script in package.json with npm Start

As a newcomer to the world of web development and React, you may encounter a common problem when working with Node.js and npm. Imagine you're trying to update the start script in your package.json file to run a new server script, but when you execute the command, it still runs the old script. If you've faced this frustrating situation, you're not alone. Today, we’ll walk through the solution step by step to ensure you can run your updated script successfully.

Understanding the Problem

When you attempt to run your updated start script using the command npm start, you expect it to execute the new script you specified, but instead, it continues to run the old one. Let's break down the issue:

Initial Setup: Initially, you created a simple server using the server.js file and set your start script accordingly:

Executing npm start: However, upon running npm start, the terminal executes node server.js instead of the updated command, which leads to confusion about why the changes are not being recognized.

The Solution: Properly Update the Script

Step-by-Step Instructions

To resolve this issue, you will need to correctly update your start script within the scripts block of your package.json. Here's how you can do that:

Open Your package.json: Locate the package.json file in your project directory.

Update the Scripts Section: Modify the scripts section to look like this:

Run the New Script: Instead of running npm start, which looks for the start command, you’ll now run your new script with the following command:

Explanation of Changes

Naming Your Custom Script: By naming your custom script start-time, you can have multiple scripts in your package.json without conflict. This avoids overriding the default npm start behavior.

Using npm run: To execute a script that is not named start, you need to use the npm run command followed by the script name. This differentiation allows for greater flexibility in your project setup.

Conclusion

By following these steps, you can successfully execute your updated server script in Node.js using npm. This simple adjustment ensures that your development process is efficient and that you're working with the most current version of your server code. Don’t forget, with npm run start-time, you’re not just addressing one issue; you’re also learning valuable skills for handling script execution in your projects moving forward.

With this newfound knowledge, you can confidently adapt your project’s package.json and tackle any future challenges that come your way. Happy coding!
