ignore-walk

What is ignore-walk?

The ignore-walk npm package is a Node.js library used to create a list of files in a directory tree while honoring .ignore rules, similar to how tools like git and npm ignore files based on .gitignore or .npmignore files. It is particularly useful for applications that need to process file trees while excluding files that should be ignored according to specified patterns.

What are ignore-walk's main functionalities?

Walking a directory while respecting .ignore files

This feature allows you to walk through a directory and list all files that are not excluded by the ignore rules specified in .ignore files such as .gitignore. The function returns a promise that resolves with the list of files.

const IgnoreWalk = require('ignore-walk');

IgnoreWalk({
  path: './path/to/directory',
  ignoreFiles: ['.gitignore']
}).then(files => {
  console.log('Files:', files);
}).catch(err => {
  console.error('Error:', err);
});

Other packages similar to ignore-walk

glob

The 'glob' package provides functionality to match files using the patterns the shell uses, like stars and stuff. It can be configured to ignore files based on patterns, which is similar to ignore-walk, but glob is more focused on pattern matching rather than strictly interpreting .ignore files.

findit

Findit is another Node.js module that walks the file system recursively. It can be used to find files and directories, but unlike ignore-walk, it does not natively support ignoring files based on .ignore files, requiring manual handling of such functionality.

README

ignore-walk

Nested/recursive .gitignore/.npmignore parsing and filtering.

Walk a directory creating a list of entries, parsing any .ignore files met along the way to exclude files.

USAGE

const walk = require('ignore-walk')

// All options are optional, defaults provided.

// this function returns a promise, but you can also pass a cb
// if you like that approach better.
walk({
  path: '...', // root dir to start in. defaults to process.cwd()
  ignoreFiles: [ '.gitignore' ], // list of filenames. defaults to ['.ignore']
  includeEmpty: true|false, // true to include empty dirs, default false
  follow: true|false // true to follow symlink dirs, default false
}, callback)

// to walk synchronously, do it this way:
const result = walk.sync({ path: '/wow/such/filepath' })

If you want to get at the underlying classes, they're at walk.Walker and walk.WalkerSync.

OPTIONS

• path The path to start in. Defaults to process.cwd()

• ignoreFiles Filenames to treat as ignore files. The default is ['.ignore']. (This is where you'd put .gitignore or .npmignore or whatever.) If multiple ignore files are in a directory, then rules from each are applied in the order that the files are listed.

• includeEmpty Set to true to include empty directories, assuming they are not excluded by any of the ignore rules. If not set, then this follows the standard git behavior of not including directories that are empty.

  Note: this will cause an empty directory to be included if it would contain an included entry, even if it would have otherwise been excluded itself.

  For example, given the rules * (ignore everything) and !/a/b/c (re-include the entry at /a/b/c), the directory /a/b will be included if it is empty.

• follow Set to true to treat symbolically linked directories as directories, recursing into them. There is no handling for nested symlinks, so ELOOP errors can occur in some cases when using this option. Defaults to false.
