Executing 'npm start' to launch an HTML file along with a CSS stylesheet - A step-by-step guide

As a newcomer to the world of coding, I've found that asking questions on platforms like Stack Overflow enables me to connect with fellow developers.

I usually code using VS Code and rely on the "live server" extension to quickly test my code. However, when attempting to start a simple HTML/CSS/JS project recently, I encountered the following error:

npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path C:\Users\.\..\...\....\package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'C:\Users\.\..\...\....\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

After some investigation, I learned that running npm install or npm init might resolve the issue.

Unfortunately, neither solution fixed the problem. Even after creating the package.json file through npm init, the issue persisted.

Furthermore, setting up the "start" script as required by npm init did not solve the issue either.

I have already tried:

  1. Deleting all .json files and running npm install.
  2. Running npm init and adding the "start" script.
  3. Rebooting my computer.
  4. Uninstalling and reinstalling VS Code.
  5. Recreating the entire project on another computer.

Despite these efforts, I remain stuck on this issue and unsure of what steps to take next.

Let me start by clarifying that you can easily view a basic HTML, CSS, and JS project without the need for npm or live server. Simply open the HTML file in your web browser. Now, let's discuss the purpose of npm commands, as they may seem confusing at first.

  • When you use npm init, it sets up a new package or modifies an existing one (creating package.json).
  • npm install is used to install all necessary packages for your project based on the dependencies listed in package.json.

The start command in package.json specifies the code that will be executed when you type npm start. In essence, running a start command is only necessary if your application requires a server, which is not the case for a simple HTML, CSS, and JS project.

Live Server works similarly to the start command but is offered as an extension in VSCode. Another helpful extension for working with basic HTML, CSS, and JS files is "Open in default browser."
