Monitor changes in files and react to them in the way you need.

npm i -g harceli

1. Create a harceli.config.json file in your project's directory. Example:

{
    "watched": [
        {
            "files": ["exampleFile.js"],
            "on_write": "echo test!"
        },
        { 
            "files": "test.js",
            "on_write": "node path/to/epic/node_file.js"
        }
    ]
}

2. Run harceli

harceli 

Now, everytime you change and save your watched files, the on_write command shall be evaluated.
