@sfomin/for-each-package

---

Runs command for each npm package under current working directory.

Features

• searches for npm packages under the current directory recursively and executes the specified command for each found package
• respects .gitignore settings of your project
• can filter packages by their name from package.json
• provides both CLI and JavaScript API
• type-safe (written in TypeScript and ships with type declarations)
• supports shell expressions in commands

Installation

npm i -g @sfomin/for-each-package

CLI

The installed package provides global binary called for-each-package or a short alias fep.

Examples

for-each-package "command with args" - this would execute command for each npm package found under the current working directory (skipping the paths like /node_modules and paths from .gitignore).

E.g.: for-each-package "pwd; echo; ls -l" would print path of each package and would list all files in that directory.

The following calls will run the specified command in all packages that match @acme/* pattern:

• for-each-package --name "@acme/*" "command" or
• for-each-package -n "@acme/*" "command" or
• fep -n "@acme/*" "command"

Options (CLI)

--name | -n - filters found packages by name using the specified glob pattern or regular expression. Regular expression should be specified this way: "/^@acme\/$/" (between two slashes). Glob pattern should adhere to the extended format supported by glob-to-regexp.

JavaScript API

This package could also be used programmatically, i.e. directly from your Node.js program:

import { forEachPackage } from '@sfomin/for-each-package';

await forEachPackage({
  cwd: '/var/packages',
  command: 'pwd && ls -l',
  packageName: /^@acme\//
});

Options (JS API)

command: string - shell command to execute for each found package

cwd?: string - root directory that should be searched for packages

packageName?: string | RegExp - package name filter glob pattern or RegExp

shell?: (boolean | string) = true - whether to use shell to execute the specified command

• false - do not use shell
• true (default) - use default shell (/bin/sh on UNIX and cmd.exe on Windows)
• string - use the specified shell
