npm-run-path

Get your PATH prepended with locally installed binaries

In npm run scripts you can execute locally installed binaries by name. This enables the same outside npm.

Install

npm install npm-run-path

Usage

import childProcess from 'node:child_process';
import {npmRunPath, npmRunPathEnv} from 'npm-run-path';

console.log(process.env.PATH);
//=> '/usr/local/bin'

console.log(npmRunPath());
//=> '/Users/sindresorhus/dev/foo/node_modules/.bin:/Users/sindresorhus/dev/node_modules/.bin:/Users/sindresorhus/node_modules/.bin:/Users/node_modules/.bin:/node_modules/.bin:/usr/local/bin'

// `foo` is a locally installed binary
childProcess.execFileSync('foo', {
    env: npmRunPathEnv()
});
