npmignore NPM version

Command line tool for creating or updating a .npmignore file based on .gitignore.

Usage

Say .gitignore has:

node_modules/
build/

… so that build output is not committed, and you want .npmignore to have:

node_modules/
src/
test/

… so that source files and test files are not published, but build output is.

Automatic usage

On the command line, run npm install --save-dev npmignore.

In your .gitignore, add .npmignore so that the .npmignore file is no longer committed to version control.

In your package.json, add the following JSON to “scripts” and “publishConfig”:

"scripts": {
    
    "prepack": "npmignore --auto"
    
},
"publishConfig": {
    
    "ignore": [
        "!build/",
        "src/",
        "test/"
    ]
    
}

Whenever you run npm pack or npm publish, an .npmignore file will automatically be created:

node_modules/
build/

# npmignore
!build/
src/
test/

Manual usage

On the command line run:

npx npmignore -i src/,test/,!build/

An .npmignore file will be created, or updated:

node_modules/
build/

# npmignore
!build/
src/
test/

Heads up!

The # npmignore comment is used to ensure that .npmignore reflects the latest changes in your .gitignore file, just by running npmignore in the command line.

_If you want to preserve everything in your .npmignore file, regardless of what is in .gitignore, just add the # npmignore comment at the top of the .npmignore file.

Verification

Run npm pack --dry-run (or npm publish --dry-run) in a modern version of npm to get a printout of the files that will be included in your npm package.

CLI commands

  • --auto: automatic mode. The --ignore, --unignore, keepdest, and --npmignore options are incompatible with this mode.
  • -i|--ignore: comma-separated list of patterns to add to .npmignore
  • -u|--unignore: comma-separated list of patterns to remove from .npmignore. This will not un-ignore patterns in .gitignore.
  • -d|--dest: optionally define a different destination filepath. Good for test driving to see what will be generated in advance.
  • -g|--gitignore: alternate source filepath for .gitignore.
  • -n|--npmignore: alternate source filepath for .npmignore.
  • -k|--keepdest: avoids altering the destination file
  • --commentLines: a comma-separated list of lines of comment text.

API

To use via API, first:

npm install --save npmignore

Then:

var npmignore = require('npmignore');

npmignore(npm, git, options);

  • npm {String|Array}: String from .npmignore or an array of patterns to use.
  • git {String|Array}: String from .gitignore or an array of patterns to use.

          'see npmjs.com/npmignore for more details.'
      ]
      
    • ignore Array of patterns to add to the existing patterns from .gitignore
    • unignore Array of patterns to remove from .npmignore. This will not un-ignore patterns in .gitignore
