Configurations

Recipes

Recipe is a set of the commands and default settings. Recipe 'Deploy' extends recipe 'Common' and contains a list of commands:

dep.task('default', [
    'deploy.prepare',
    'deploy.lock',
    'deploy.release',
    'deploy.symlink',
    'deploy.cleanup',
    'deploy.unlock',
    'success',
  ]);

Tasks

Task is the special linux command to excute. Default package task can be overwritten with local file with the same name. Each task can be a closure function (with one argument - client), object with other tasks or string with file name.

Proxy

This package currently does not support proxy

Server

• stage: the server stage.
• deploy_path: your application release path.
• connectOptions: see node-ssh2 client connect configuration.

Events

• ready: when all clents connected, this event will be fire.
• done: All task completed.

Methods

• servers(< object >servers): add remote servers list.
• task(< string >name, < object >closure, < object >options): add new task
• set(< string >name,< object >options): set variable
• get(< string >name): get variable
• run(< string >task): run a remote server.

Variables

You can use default or custom variables in commands

dep.set('source_directory', path.resolve('./build'))

...

client.test('[ -d ${deploy_path}/releases ] && [ "$(ls -A ${deploy_path}/releases)" ]')

Examples

const fs = require('fs')
const path = require('path')

module.exports = (dep) => {

  dep = require('@hexide-digital/node-deployer/lib/recipes/deploy')(dep)

  dep.servers(
    [
      {
        'name': 'servername',
        'stage': 'dev',
        'releasePath': '/var/www',
        'connectOptions': {
          'host': '127.0.0.1',
          'port': 22,
          'username': 'root',
          'privateKey': fs.readFileSync(path.resolve('.ssh/id_rsa'))
          // "password": "123456"
        }
      }
    ]
  )

  return dep
}

Todo

This package is still in beta. Please, send your requests. I'll apply them asap. First thing needed to be done is files upload. Probably best choice would be archive all files in dist directory into single file, upload it to remote server and unzip it. For now each file uploads separately one by one. That is OK for small project but may be headache.
