assert-modules-support-case-insensitive-fs

Assert that JS and TS modules support case-insensitive file systems.

Install

Requires node@14 or higher:

npm install assert-modules-support-case-insensitive-fs --save-dev

Usage

This package takes a list of paths, and checks all directories and all subdirectories (at all nesting levels) along those paths.

Checking one directory consists in searching in this directory for two JS (or TS, or .vue, or .cjs, or .mjs, or .json) modules whose names differ only in case. If there are such modules, the package throws an exception specifying these modules, because in a case-insensitive file system, such modules will not be distinguished (without specifying extensions).

Examples of directories throwing an exception:

foo/
├── bar.js
└── Bar.js

foo/
├── bar.js
└── baR.ts

foo/
├── Bar/
└── bar.cjs

foo/
├── BAR.jsx
└── Bar.tsx

foo/
├── BAR.json
└── bAr.mjs

Examples of directories passing validation (not throwing an exception):

foo/
├── Bar.jsx
└── Bar.tsx

foo/
├── bar.js
├── bar.ts
├── bar.mjs
└── bar.json

foo/
├── Bar/
├── Bar.vue
└── Bar.tsx

foo/
├── bar.js
└── Bar.css

CLI

Assert that JS and TS modules in directory src and all it subdirectories support case-insensitive file systems:

npx assert-modules-support-case-insensitive-fs src

Assert modules in directories src and bin:

npx assert-modules-support-case-insensitive-fs src bin

JavaScript/TypeScript API
