Running NPM modules locally
06 May 2017
When a node module is globally installed using npm install webpack -g
, we can access it from the command prompt as> webpack ./entry.js bundle.js
Consider if you want a particular version of package for a project/folder. Then you will install the package without -g
for that project alone, then you can't access the package directly as mentioned above.
To execute you can do one of the following
- Navigate to
./node_modules/webpack/
folder and then execute above statement with the JS file paths fixed. but this might create many confusions when you have multiple bundles. - If you don't have
packages.json
in your folder then performnpm init
, after which you can add following npm run-scripts like below
{
"scripts": {
"build": "webpack ./entry.js bundle.js --module-bind \"css=style-loader!css-loader\"",
"test": "echo \"Error: no test specified\" && exit 1"
}
}
The above build script can be triggered using npm run build
from command prompt.
This will allow you to run the package using your local modules from "node_modules/packagename/"
, if not found then it automatically checks global.
Note:
When running the build command in Windows, the loader options should be escaped using\"
as shown above.
