## Supported Node.js Versions

| Version | Supported Level |

| :------ |:--------------- |

| <= 10   | Not supported   |

| 12      | Supported       |

| >= 14   | Recommended     |

## Getting Started

### Node.js Installation

Node.js 14 or higher is recommended. You can install [Node Version Manager](https://github.com/creationix/nvm) to manage multiple Node.js versions. If you have `git` installed, just clone the `nvm` repo, and check out the latest version:

```

git clone https://github.com/creationix/nvm.git ~/.nvm

cd ~/.nvm

git checkout `git describe --abbrev=0 --tags`

cd ..

. ~/.nvm/nvm.sh

```

Add these lines to your `~/.bash_profile`, `~/.bashrc`, or `~/.profile` file to have it automatically sourced upon login: 

```bash

export NVM_DIR="$HOME/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

```

Once installed, you can select Node.js versions with:

```

nvm install 14

nvm use 14

```

It's also recommended that you upgrade npm to the latest version. To upgrade, run:

```

npm install npm@latest -g

```

### Installation

Install cncjs as a non-root user, or the [serialport](https://github.com/node-serialport/node-serialport) module may not install correctly on some platforms like Raspberry Pi.

```

npm install -g cncjs

```

If you're going to use sudo or root to install cncjs, you need to specify the `--unsafe-perm` option to run npm as the root account.

```

sudo npm install --unsafe-perm -g cncjs

```

Check out [https://github.com/cncjs/cncjs/wiki/Installation](https://github.com/cncjs/cncjs/wiki/Installation) for other installation methods.

### Upgrade

Run `npm install -g cncjs@latest` to install the latest version. To determine the version, use `cncjs -V`.

### Usage

Run `cncjs` to start the server, and visit `http://yourhostname:8000/` to view the web interface. Pass `--help` to `cncjs` for more options.

```

pi@rpi3$ cncjs -h

  Usage: cncjs [options]

  Options:

    -V, --version                       output the version number

    -p, --port                    Set listen port (default: 8000)

    -H, --host                    Set listen address or hostname (default: 0.0.0.0)

    -b, --backlog              Set listen backlog (default: 511)

    -c, --config              Set config file (default: ~/.cncrc)

    -v, --verbose                       Increase the verbosity level (-v, -vv, -vvv)

    -m, --mount :   Add a mount point for serving static files

    -w, --watch-directory         Watch a directory for changes

    --access-token-lifetime   Access token lifetime in seconds or a time span string (default: 30d)

    --allow-remote-access               Allow remote access to the server (default: false)

    --controller                  Specify CNC controller: Grbl|Marlin|Smoothie|TinyG|g2core (default: '')

    -h, --help                          output usage information

  Examples:

    $ cncjs -vv

    $ cncjs --mount /pendant:/home/pi/tinyweb

    $ cncjs --mount /widget:~+/widget --mount /pendant:~/pendant

    $ cncjs --mount /widget:https://cncjs.github.io/cncjs-widget-boilerplate/v1/

    $ cncjs --watch-directory /home/pi/watch

    $ cncjs --access-token-lifetime 60d  # e.g. 3600, 30m, 12h, 30d

    $ cncjs --allow-remote-access

    $ cncjs --controller Grbl

```

Instead of passing command line options for `--watch-directory`, `--access-token-lifetime`, `--allow-remote-access`, and `--controller`, you can create a `~/.cncrc` file that contains the following configuration in JSON format:

```json

{

    "mountPoints": [

        {

            "route": "/pendant",

            "target": "/home/pi/tinyweb"

        },

        {

            "route": "/widget",

            "target": "https://cncjs.github.io/cncjs-widget-boilerplate/v1/"

        }

    ],

    "watchDirectory": "/path/to/dir",

    "accessTokenLifetime": "30d",

    "allowRemoteAccess": false,

    "controller": ""

}

```

To troubleshoot issues, run:

```

cncjs -vvv

```

### Configuration File

The configuration file .cncrc contains settings that are equivalent to the cncjs command-line options. The configuration file is stored in user's home directory. To find out the actual location of the home directory, do the following:

* Linux/Mac

  ```sh

  echo $HOME

  ```

* Windows

  ```sh

  echo %USERPROFILE%

  ```

Check out an example configuration file [here](https://github.com/cncjs/cncjs/blob/master/examples/.cncrc).

## Examples

There are several *.gcode files in the [examples](https://github.com/cncjs/cncjs/tree/master/examples) directory. You can use the GCode widget to load a GCode file and make a trial run.

If you don't have a CAM software, try using [jscut](http://jscut.org/) to create G-Code from *.svg. It's a simple CAM package that runs in the browser.

Check out a live demo at http://jscut.org/jscut.html.
