prok

Run multiple processes, simply.

A lighter, more focused alternative to node-forman. This is not aiming to have feature parity with foreman. I would only use this in development.

This is a WIP and the API may evolve or change.

Installation

npm install prok

Features

• Processes live and die as a group. This makes it easier to manage multiple processes.
• Filter logs by process name (ex. LOG=web:*)
• Specify processes to run by added a processes key to your package.json
• Procfile parser and environment parser well tested from node-foreman
• Supports arbitrary Procfile and environment configurations
• API for running processes
• Much cleaner logging
• Doesn't ruin DEBUG

Not supported

• Exporting configuration to upstart, systemd, etc.
• Starting multiple jobs of the same type (accepting PRs)

CLI

Usage: prok [options] [Procfile]

Options:

  -h, --help        output usage information
  -V, --version     output the version number
  -e, --env <file>  specify an environment configuration file

Example:

  $ prok -e .env Procfile

Why the fragmentation?

Node Foreman does a good job getting processes to run together. It does not do a good job with logging. Spacing gets trimmed, timestamps take up too much space, etc.

Troubleshooting

In-memory databases

Don't put in memory databases in this process manager unless you want to lose your changes on restart. However, if you're working with redis, you can specify a development configuration with the property:

SAVE 1 1

This will check the database every second and if one or more keys have changed, it will update. I don't think I have to say this, but this is not suitable for production.

Restart node on development changes

If you don't like killing all the processes for each change you make to a file, place node-dev or nodemon in your Procfile.
