Ws-Filewatcher

Ws-Filewatcher is a cli that will watch for file change and open a websocket server where it will send a message everytime the file is updated

:zap: Requirements

• Npm or Yarn, the package managers for NodeJs

:wrench: Installation

Here are the instruction to install the cli globally, but you can do it locally on your projects.

npm i -g ws-filewatcher
OR
yarn global add ws-filewatcher

:fire: Usage

Here is the minimum you need to write to launch the service:

ws-filewatcher -f path/to/my/file

:warning: 'path/to/my/file' isn't necessarily an existing file. You may want to listen for a file creation. So if you make a typo in the path, it won't be considered as an error

Options

| | Verbose | | ------------- | --------------- | | parameter | --verbose | | shortcut | -v | | default value | (bool)false | | description | Allow loggings |

| | Port | | ------------- | ------------------------------------ | | parameter | --port | | shortcut | -p | | default value | (number)9999 | | description | Set the port of the WebSocket server |

| | Command | | ------------- | -------------------------------------------- | | parameter | --command | | shortcut | -c | | default value | (string)"" | | description | The command will be run on every file update |

Full example

ws-filewatcher -f path/to/my/file -p 8080 -v -c 'cp folder/file other/folder/file'

Client example

The example assume you are running the code inside a browser

const ws = new WebSocket('ws://localhost:9999')

    console.log('My file was updated!')
}
