# serviceman
|
||||
|
||||
A cross-platform service manager
|
||||
|
||||
```bash
|
||||
serviceman add --name "my-project" node ./serve.js --port 3000
|
||||
serviceman stop my-project
|
||||
serviceman start my-project
|
||||
```
|
||||
|
||||
Works with launchd (Mac), systemd (Linux), or standalone (Windows).
|
||||
|
||||
## Meta Package
|
||||
|
||||
This is a meta-package to fetch and install the correction version of
|
||||
[go-serviceman](https://git.rootprojects.org/root/serviceman)
|
||||
for your architecture and platform.
|
||||
|
||||
```bash
|
||||
npm install serviceman
|
||||
```
|
||||
|
||||
## How does it work?
|
||||
|
||||
1. Resolves executable from PATH, or hashbang (ex: `#!/usr/bin/env node`)
|
||||
2. Resolves file and directory paths to absolute paths (ex: `/Users/me/my-project/serve.js`)
|
||||
3. Creates a template `.plist` (Mac), `.service` (Linux), or `.json` (Windows) file
|
||||
4. Calls `launchd` (Mac), `systemd` (Linux), or `serviceman-runner` (Windows) to enable/start/stop/etc
