unwrap-npm-cmd

Unwrap npm's node.js bin CMD batch for js files on Windows.

Sample:

const unwrapNpmCmd = require("unwrap-npm-cmd");
console.log(unwrapNpmCmd("npm test"));
console.log(unwrapNpmCmd("npx mocha", { relative: true }));
console.log(unwrapNpmCmd("mocha test", { jsOnly: true }));
console.log(unwrapNpmCmd(`find "name" package.json`));
console.log(unwrapNpmCmd("hello world", { path: __dirname }));

Output:

"C:\Users\userid\nvm\nodejs\bin\node.exe" "C:\Users\userid\nvm\nodejs\bin\node_modules\npm\bin\npm-cli.js" test
"C:\Users\userid\nvm\nodejs\bin\node.exe" "..\nvm\nodejs\bin\node_modules\npm\bin\npx-cli.js" mocha
"C:\Users\userid\unwrap-npm-cmd\node_modules\mocha\bin\mocha" test
"C:\WINDOWS\system32\find.EXE" "name" package.json
"C:\Users\userid\unwrap-npm-cmd\test\fixtures\hello.CMD" world

Usage

child.spawnSync(unwrapNpmCmd("mocha test", { relative: true }));

Would effectivly be doing:

child.spawnSync(
  `"C:\\Users\\userid\\nvm\\nodejs\\bin\\node.exe" ".\\node_modules\\mocha\\bin\\_mocha" test`
);
