What is the process for getting involved with npm commands?

Here is an excerpt from my package.json file:

"scripts": {
   "cpFile": cp ../template/index.js /src/view/home/
}

When I try to run the command:

npm run cpFile fileName.js

I expect it to execute:

cp ../template/index.js /src/view/home/fileName.js

However, it does not work as expected.

Answer №1

To begin, make sure to enclose your command in quotes

"scripts": {
   "cpFile": "cp ../template/index.js /src/view/home/"
}

If you want to include arguments, you will need to use the args delimiter

> npm run cpFile -- fileName.js
>> cp ../template/index.js /src/view/home/ "fileName.js" 

This may not be what you intended

You can find more information about it here:

> npm help run

Edit

You may need to provide the full path to achieve your desired outcome.

"scripts": {
   "cpFile": "cp ../template/index.js "
}

Then:

> npm run cpFile -- /src/view/home/fileName.js

Answer №2

Unfortunately, the serialization process of JSON does not support functions, RegEx, or error-objects. Moreover, the JSON format you have provided is not valid.

A valid JSON format should begin and end with curly braces { }, and most names and values must be enclosed in quotes, except for numeric values and booleans.

{ "scripts": { "cpFile": "cp ../template/index.js /src/view/home/" } }

It is important to note that there is no built-in method to execute JavaScript without the use of plugins, as most browsers require.

One possible solution could be using curl to run the script.
