Ease your Node.js development by automatically restarting your application on file changes and solve the notorious Docker node_modules sync issue as supermon monitors package.json file and installs any missing modules to the internal Docker volume as well.

Supports TypeScript applications out of the box through ts-node.

Install

npm install supermon --save-dev

To use supermon with TypeScript you also need to install ts-node

npm install ts-node --save-dev

Usage

supermon [application file]

Examples

supermon app.js
supermon app.ts

      to use "--" as separator between supermon and application command & arguments.
      Example: "supermon --delay=2000 -- app.js --port=80"

Note: Boolean options do not require value to be specified

Example use: "supermon app.js"
Example use: "supermon --delay=2000 -- app.js --port=80"

Config file

Supermon supports setting all your options through single configuration file, supermon.json.

Example:

{
  "delay": 2000
}

package.json

If you want to keep your amount of config files to minimum, you can also set the options through supermon object in package.json.

Example:

{
  "name": "my-awesome-project",
  "version": "0.0.1",
  "...": "...",
  "supermon": {
    "delay": "2000"
  }
}

Environment variables

All options can also be set though environment variables with SUPERMON_ prefix.

Example:

SUPERMON_DELAY=2000
