npm-packlist

Get a list of the files to add from a folder into an npm package

These can be handed to tar like so to make an npm package tarball:

const packlist = require('npm-packlist')
const tar = require('tar')
const packageDir = '/path/to/package'
const packageTarball = '/path/to/package.tgz'
packlist({ path: packageDir })
.then(files => tar.create({
prefix: 'package/',
cwd: packageDir,
file: packageTarball,
gzip: true
}, files))
.then(_ => {
// tarball has been created, continue with your day
})

This uses the following rules:

1. If a `package.json` file is found, and it has a `files` list, then ignore everything that isn't in `files`. Always include the readme, license, notice, changes, changelog, and history files, if they exist, and the package.json file itself.
2. If there's no `package.json` file (or it has no `files` list), and there is a `.npmignore` file, then ignore all the files in the `.npmignore` file.
3. If there's no `package.json` with a `files` list, and there's no `.npmignore` file, but there is a `.gitignore` file, then ignore all the files in the `.gitignore` file.
4. Everything in the root `node_modules` is ignored, unless it's a bundled dependency. If it IS a bundled dependency, and it's a symbolic link, then the target of the link is included, not the symlink itself.

1. Unless they're explicitly included (by being in a `files` list, or a `!negated` rule in a relevant `.npmignore` or `.gitignore`), always ignore certain common cruft files:

   1. .npmignore and .gitignore files (their effect is in the package already, there's no need to include them in the package)
   2. editor junk like `.*.swp`, `._*` and `.*.orig` files
   3. `.npmrc` files (these may contain private configs)
   4. The `node_modules/.bin` folder
   5. Waf and gyp cruft like `/build/config.gypi` and `.lock-wscript`
   6. Darwin's `.DS_Store` files because wtf are those even
   7. `npm-debug.log` files at the root of a project

   You can explicitly re-include any of these with a `files` list in `package.json` or a negated ignore file rule.

# API

Same API as ignore-walk, just hard-coded file list and rule sets.

The `Walker` and `WalkerSync` classes take a `bundled` argument, which is a list of package names to include from node_modules. When calling the top-level `packlist()` and `packlist.sync()` functions, this module calls into `npm-bundled` directly.
