Is Git

Create a progrm that checks if a directory in the file system is also a git repository.

Instructions

1. Complete the function

In the file is-git.js complete the exported function using the directory-exists library to check if a relative path contains a .git directory.

Constraints (Task 1)

• The function should return a string indicating whether a git repository exists in passed path or not.
• The function should recieve a relative path, but return a string contaning the absolute path (see examples below)
• If a direcotry doesn't exist in the passed path, the function should exit the process and print message to the user.

Examples (Task 1)

| Case | Input | Output | |------|-------|--------| | Input is not a directory | '../hello' | Sorry, but I couldn't find a directory at /home/itamar/hello | | Input is git repository | './blockly-vue' | /home/itamar/blockly-vue is a git repository | | Input is not git repository | './blockly-vue/src' | /home/itamar/blockly-vue/src is **not** a git repository |

2. Create a cli program

In the file index.js accept at least one command line argument from the user, and import the function from is-git.js to check if the argument is a git repository.

Constraints (Task 2)

• If no arguments are passed, the program should exit the process and print a message to the user (see examples below)
• Add support for multiple arguments

Examples (Task 2)

Directory is a git repository

$ node index.js ../blockly-vue
> "/home/itamar/blockly-vue is a git repository"

Directory is not a git repository

$ node index.js ../blockly-vue/src
> "/home/itamar/blockly-vue/src is **not** a git repository"

Directory doesn't exist

$ node index.js ../hello
> "Sorry, but I couldn't find a directory at /home/itamar/hello"

No arguments passed

$ node index.js
> "Please pass in at least one directory path to check for git repositories"

Multiple Arguments

$ node index.js ../blockly-vue ../blockly-vue/src
> "/home/itamar/blockly-vue is a git repository"
> "/home/itamar/blockly-vue/src is **not** a git repository"

Bonus tasks

• Use the external library chalk to add some color to your output.
• Link the npm package globally so that you could use the program anywhere in the terminal by calling is-git <directory>.
• Publish the program as an npm package under your user namespace.
