Node.jsでユーザーのホームディレクトリのパスを取得する

Last updated at Posted at 2016-08-24

Node.jsでホームディレクトリを取得したい場合、特にmoduleのrequireは必要とせず、以下のコードで取得が可能。

main.js
console.log(process.env[process.platform == "win32" ? "USERPROFILE" : "HOME"]);
// /Users/foo/

デスクトップやDocumentsを指定したい場合はpathを利用して。

main.js
const path = require("path");
const userHome = process.env[process.platform == "win32" ? "USERPROFILE" : "HOME"];

console.log(path.join(userHome, "Desktop"));
// /Users/foo/Desktop

console.log(path.join(userHome, "Documents"));
// /Users/foo/Documents
