Hello everyone, I'm new here and appreciate any help in advance!
I'm currently working on my first project and encountering some challenges. The biggest one is that whenever I try to run npm start, I keep getting an error message:
I've attempted running npm install beforehand but it doesn't seem to solve the issue. Does anyone have any suggestions?
Thank you!
It's difficult to provide a definitive answer without examining the contents of the package.json file. As some comments have pointed out, it's important to ensure that your node or npm command can locate and execute your script file.
Two key concepts to consider are node and npm.
1. Node as a runtime:
To run a node script, you'll need to use the node command within your project directory like this:
node ./folder/to/your-script.js
2. NPM as a package manager:
NPM relies on having a package.json file in the same directory where commands are executed. Most npm commands require the presence of a package.json, except for init which creates the initial file.
The error message from running npm start indicates that a script named "start" is missing in the scripts section of the package.json.
This suggests confusion between executing scripts directly with node <filename.js> and using npm commands such as npm run <script>.
A special case worth noting is npm start which behaves differently compared to other npm run commands.
To align with your expectations, consider modifying the package.json as shown below:
You can also define custom aliases for commands in the scripts block of the package.json:
"scripts": {
"start": "node ./some-path/to/your-script.js",
"bar": "npm run foo",
"foo": "node ./folder/to/your-script.js"
}
Notice how you can reference sibling aliases within script commands, including non-node commands like git.
With these changes in your package.json, you'll be able to execute commands such as npm start, npm run foo, or npm run bar in the project directory.
