temp-dir-cp

⚡️ Copy folder to a unique temp location

Install

yarn add temp-dir-cp
# same as npm install --save

Usage

Assume that in the current directory, there is a directory called fixtures:

$ tree
.
├── fixtures
│   └── file.txt
└── index.js

Call temp-dir-cp with "fixtures"

// index.js
const tempDirCp = require('temp-dir-cp');

tempDirCp('fixtures');
//=> '/var/folders/6r/cyh35ykj4h77jnn0lz0xqx580000gn/T/87166550876/fixtures'

tempDirCp('fixtures');
//=> '/var/folders/6r/cyh35ykj4h77jnn0lz0xqx580000gn/T/75704852254/fixtures'

Both of these newly created directory's have the contents of the fixtures directory. Each can be mutated separately without affecting one another or the source.

$ tree /var/folders/6r/cyh35ykj4h77jnn0lz0xqx580000gn/T/87166550876
└── fixtures
    └── file.txt

$ tree /var/folders/6r/cyh35ykj4h77jnn0lz0xqx580000gn/T/75704852254
└── fixtures
    └── file.txt

For any tests which modify the file-system, you can't cd into your fixtures and then run the tests. That would modify your fixtures and therefore break future tests. Use tempDirCp instead and you will have a fresh copy of your files in a unique directory every time. The unique directory is temporary too, so it gets removed on computer startup!
