Latest Version on NPM here

Check if a file/folder is hidden on all platforms.

Forked from kimlimjustin/is-hidden-file to use CMake (reliable!) instead of node-gyp (inscrutably broken constantly for me), with other fixes (like an obvious memory leak)

Note This will slow down your yarn install/npm installs, particularly on Windows! The speed hit seems unavoidable. Package managers are terrible at understanding build dependencies, so they'll rebuild this whenever it gets installed, even if nothing changed. And the rebuild invokes some platform specific shim which is kind of slow. Once the shim is done, Linux and MacOS move merrily on their way. Windows, however, invokes the cmake build system, followed by the C++ compiler & linker, all of which is quite slow. The solution to this is to get the NodeJS runtime to add support for this to the path or fs modules... It's gotten bad enough that I'm digging for solutions like including pre-built x86 and AMD64 binaries in the NPM package...

• On *nix: Check file name starts with ..
• On Windows: Check if the file is hidden using native code.

• npm: npm i is-hidden-file
• yarn: yarn add is-hidden-file

It's packaged as both CJS and ESM: Use which module type your ecosystem requires. Typescript types are also included.

import { isHiddenFile } from 'is-hidden-file';
// Or this for CJS:
// const { isHiddenFile } = require('is-hidden-file');

console.log(isHiddenFile('.git')); // true
console.log(isHiddenFile('README.md')); // false

MIT, cuz that's what the original was licensed with.
