@aship/core v0.1.2

@aship/core

Core library for aship, providing APIs and utilities for Ansible management, SSH connections, and configuration handling.

This package contains the core business logic and can be used independently to build custom Ansible management tools.

🏗️ Architecture

This package provides:

• Configuration Management: Project and server configuration handling with YAML/JSON support
• Ansible Integration: Playbook execution, inventory management, and parameter handling
• SSH Management: Connection handling, authentication, and session management
• Server Management: Server configuration, connection testing, and permission detection
• Schema Validation: Zod-based validation for all configuration formats
• Utility Functions: File operations, network connectivity, and retry mechanisms

📦 Installation

Prerequisites

• Node.js 18.0.0 or higher

Install

# Install as dependency
npm install @aship/core

# Or using pnpm
pnpm add @aship/core

🔧 API Usage

Configuration Management

import { ConfigurationManager, RuntimeConfigManager } from '@aship/core';

// Load project configuration
const configManager = new ConfigurationManager('/path/to/aship.yml');
const config = await configManager.loadConfig();

// Manage runtime configuration (hosts, cache)
const runtimeManager = new RuntimeConfigManager('/path/to/project');
const servers = await runtimeManager.loadServers();

Ansible Execution

import { AnsibleExecutor } from '@aship/core';

// Execute an Ansible playbook
const executor = new AnsibleExecutor();
const result = await executor.executePlaybook({
  servers: [{ hostname: 'example.com', user: 'deploy', port: 22 }],
  playbook: 'playbooks/deploy.yml',
  extraVars: {
    environment: 'production',
    version: '1.2.3'
  },
  ansibleArgs: ['--tags', 'web,database', '--verbose'],
  cwd: '/path/to/project'
});

// Execute Ansible modules directly
const moduleResult = await executor.executeAnsible({
  servers: [{ hostname: 'example.com', user: 'deploy', port: 22 }],
  pattern: 'all',
  module: 'shell',
  args: 'uptime',
  cwd: '/path/to/project'
});

Host Management

import { HostManager, DirectoryManager } from '@aship/core';

// Host management
const directoryManager = new DirectoryManager();
const hostManager = new HostManager(directoryManager);

// Add a host
await hostManager.addHost({
  hostname: 'prod.example.com',
  user: 'deploy',
  port: 22,
  description: 'Production web server',
  source: 'manual'
}, 'production-web');

// Get all hosts
const hosts = await hostManager.getHosts();

SSH Connection Management

import { testConnectionWithRetry, connectToServer } from '@aship/core';

// Test SSH connection
const result = await testConnectionWithRetry({
  hostname: 'example.com',
  user: 'deploy',
  port: 22,
  identity_file: '~/.ssh/id_rsa'
});

// Establish SSH connection
const connection = await connectToServer({
  hostname: 'example.com',
  user: 'deploy',
  port: 22
});

🔌 Extensibility

The core package is designed to be extensible:

// Custom configuration manager
class CustomConfigManager extends ConfigurationManager {
  async loadConfig() {
    // Custom configuration loading logic
    return super.loadConfig();
  }
}

// Custom Ansible executor
class CustomAnsibleExecutor extends AnsibleExecutor {
  async executePlaybook(options) {
    // Custom pre-execution logic
    return super.executePlaybook(options);
  }
}
