## Cloning PM2 development
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ git clone https://github.com/Unitech/pm2.git
|
||
|
|
$ cd pm2
|
||
|
|
$ git checkout development
|
||
|
|
$ npm install
|
||
|
|
```
|
||
|
|
|
||
|
|
I recommend having a pm2 alias pointing to the development version to make it easier to use pm2 development:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd pm2/
|
||
|
|
$ echo "alias pm2='`pwd`/bin/pm2'" >> ~/.bashrc
|
||
|
|
```
|
||
|
|
|
||
|
|
You are now able to use pm2 in dev mode:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ pm2 update
|
||
|
|
$ pm2 ls
|
||
|
|
```
|
||
|
|
|
||
|
|
## Project structure
|
||
|
|
|
||
|
|
```
|
||
|
|
.
|
||
|
|
├── bin // pm2, pmd, pm2-dev, pm2-docker are there
|
||
|
|
├── examples // examples files
|
||
|
|
├── lib // source files
|
||
|
|
├── pres // presentation files
|
||
|
|
├── test // test files
|
||
|
|
└── types // TypeScript definition files
|
||
|
|
```
|
||
|

|
## Modifying the Daemon
|
||
|
|
|
||
|
|
When you modify the Daemon (lib/Daemon.js, lib/God.js, lib/God/*, lib/Watcher.js), you must restart the pm2 Daemon by doing:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ pm2 update
|
||
|
|
```
|
||
|
|
|
||
|
|
## Commit rules
|
||
|
|
|
||
|
|
### Commit message
|
||
|
|
|
||
|
|
A good commit message should describe what changed and why.
|
||
|
|
|
||
|
|
It should :
|
||
|
|
* contain a short description of the change (preferably 50 characters or less)
|
||
|
|
* be entirely in lowercase with the exception of proper nouns, acronyms, and the words that refer to code, like function/variable names
|
||
|
|
* be prefixed with one of the following word
|
||
|
|
* fix : bug fix
|
||
|
|
* hotfix : urgent bug fix
|
||
|
|
* feat : new or updated feature
|
||
|
|
* docs : documentation updates
|
||
|
|
* BREAKING : if commit is a breaking change
|
||
|
|
* refactor : code refactoring (no functional change)
|
||
|
|
* perf : performance improvement
|
||
|
|
* style : UX and display updates
|
||
|
|
* test : tests and CI updates
|
||
|
|
* chore : updates on build, tools, configuration ...
|
||
|
|
* Merge branch : when merging branch
|
||
|
