```
Ensure that you have TypeScript and the related dependencies installed as well since `@push.rocks/smartshell` is designed to work with TypeScript.
## Usage
The `@push.rocks/smartshell` package simplifies running shell commands within Node.js applications by wrapping these commands within promises. This approach enhances the readability and maintainability of code that relies on shell execution, making it particularly useful in automation scripts, build processes, and any scenario where interaction with the system shell is required.
### Getting Started with `@push.rocks/smartshell`
First, ensure that you import `Smartshell` from `@push.rocks/smartshell` using ESM syntax in your TypeScript file:
## Quick Start 🏃‍♂️
```typescript
import { Smartshell } from '@push.rocks/smartshell';
// Create your shell instance
const shell = new Smartshell({
executor: 'bash' // or 'sh' for lighter shells
});
// Run a simple command
const result = await shell.exec('echo "Hello, World!"');
console.log(result.stdout); // "Hello, World!"
```
### Creating a Smartshell Instance
## Core Concepts 💡
Before executing any shell command, you need to create an instance of `Smartshell`. The constructor accepts configuration options such as the shell executor (`bash` or `sh`), and optionally, paths to source files and directories to include in the shells environment.
### The Smartshell Instance
The heart of smartshell is the `Smartshell` class. Each instance maintains its own environment and configuration:
```typescript
const smartShellInstance = new Smartshell({
executor: 'bash', // or 'sh'
const shell = new Smartshell({
executor: 'bash', // Choose your shell: 'bash' or 'sh'
sourceFilePaths: ['/path/to/env.sh'], // Optional: source files on init
});
```
### Executing Commands
## Execution Modes 🎛️
#### Basic Execution
### Standard Execution
To execute a shell command, use the `exec` method. This method returns a promise that resolves with an execution result object containing `exitCode` and `stdout`.
Perfect for general commands where you want to see the output:
```typescript
(async () => {
const result = await smartShellInstance.exec('echo "Hello, SmartShell"');
console.log(result.stdout); // Outputs: Hello, SmartShell
})();
const result = await shell.exec('ls -la');
console.log(result.stdout); // Directory listing
console.log(result.exitCode); // 0 for success
```
#### Silent Execution
### Silent Execution
If you prefer not to display the output in the console, use `execSilent`:
Run commands without printing to console - ideal for capturing output:
```typescript
(async () => {
const result = await smartShellInstance.execSilent('ls');
console.log(result.stdout); // Outputs the list of files and directories
})();
const result = await shell.execSilent('cat /etc/hostname');
// Output is NOT printed to console but IS captured in result
console.log(result.stdout); // Access the captured output here
console.log(result.exitCode); // Check exit code (0 = success)
// Example: Process output programmatically
const files = await shell.execSilent('ls -la');
const fileList = files.stdout.split('
');
fileList.forEach(file => {
// Process each file entry
});
```
#### Strict Execution
**Key Point:** Silent methods (`execSilent`, `execStrictSilent`, `execStreamingSilent`) suppress console output but still capture everything in the result object for programmatic access.
For scenarios where an execution error should immediately throw an exception, use `execStrict`:
### Strict Execution
Throws an error if the command fails - great for critical operations:
```typescript
(async () => {
try {
const result = await smartShellInstance.execStrict('exit 1');
await shell.execStrict('critical-command');
console.log('✅ Command succeeded!');
} catch (error) {
console.error('Command execution failed');
console.error('Command failed:', error);
}
})();
```
#### Streaming Output
### Streaming Execution
Some commands benefit from streaming output as they execute, especially long-running tasks. For these cases, use `execStreaming`:
For long-running processes or when you need real-time output:
```typescript
(async () => {
const execStreamingResult = await smartShellInstance.execStreaming('tail -f /var/log/system.log');
const streaming = await shell.execStreaming('npm install');
execStreamingResult.childProcess.stdout.on('data', (data) => {
// Access the child process directly
streaming.childProcess.stdout.on('data', (chunk) => {
console.log('📦 Installing:', chunk.toString());
});
// Wait for completion
await streaming.finalPromise;
```
### Interactive Execution
When commands need user input:
```typescript
// This will connect to your terminal for input
await shell.execInteractive('npm init');
```
## Advanced Features 🔥
### Wait for Specific Output
Perfect for waiting on services to start:
```typescript
// Wait for a specific line before continuing
await shell.execAndWaitForLine(
'npm run dev',
/Server started on port 3000/
);
console.log('🚀 Server is ready!');
```
### Silent Pattern Waiting
Same as above, but without console output:
```typescript
await shell.execAndWaitForLineSilent(
'docker-compose up',
/database system is ready to accept connections/
);
// The command output is suppressed from console but the pattern matching still works
```
### Environment Customization
Smartshell provides powerful environment management:
```typescript
// Add custom source files
shell.shellEnv.addSourceFiles([
'/home/user/.custom_env',
'./project.env.sh'
]);
// Modify PATH
shell.shellEnv.pathDirArray.push('/custom/bin');
shell.shellEnv.pathDirArray.push('/usr/local/special');
// Your custom environment is ready
const result = await shell.exec('my-custom-command');
```
### Smart Execution Utility
The `SmartExecution` class enables restartable streaming processes:
```typescript
import { SmartExecution } from '@push.rocks/smartshell';
const execution = new SmartExecution(shell, 'npm run watch');
// Restart the process whenever needed
await execution.restart();
// Access the current streaming execution
if (execution.currentStreamingExecution) {
execution.currentStreamingExecution.childProcess.stdout.on('data', (data) => {
console.log(data.toString());
});
// Remember to handle the process termination as necessary.
})();
}
```
### Advanced Usage
### Shell Detection
#### Executing With Custom Environment Variables
`smartshell` allows for the execution of commands within a modified environment, facilitating the use of custom variables or altered PATH values:
Need to check if a command exists? We export the `which` utility:
```typescript
(async () => {
smartShellInstance.shellEnv.addSourceFiles(['/path/to/envFile']);
smartShellInstance.shellEnv.pathDirArray.push('/custom/bin');
import { which } from '@push.rocks/smartshell';
const result = await smartShellInstance.exec('echo $CUSTOM_VAR');
console.log(result.stdout); // Outputs the value of CUSTOM_VAR
})();
try {
const gitPath = await which('git');
console.log(`Git found at: ${gitPath}`);
} catch (error) {
console.log('Git is not installed');
}
```
### Interactive Mode
## Real-World Examples 🌍
For commands that require interactive terminal input (not typically recommended for automated scripts), you can use `execInteractive`:
### Build Pipeline
```typescript
(async () => {
await smartShellInstance.execInteractive('npm init');
})();
const shell = new Smartshell({ executor: 'bash' });
// Clean build directory
await shell.execSilent('rm -rf dist');
// Run TypeScript compiler
const buildResult = await shell.execStrict('tsc');
// Run tests
await shell.execStrict('npm test');
// Build succeeded!
console.log('✅ Build pipeline completed successfully');
```
### Waiting for Specific Output
To wait for a specific line before proceeding, you might use `execAndWaitForLine`. This is useful for waiting on a process to log a certain message:
### Development Server with Auto-Restart
```typescript
(async () => {
await smartShellInstance.execAndWaitForLine('npm run watch', /Compilation complete./);
console.log('The watch process has finished compiling.');
})();
const shell = new Smartshell({ executor: 'bash' });
const devServer = new SmartExecution(shell, 'npm run dev');
// Watch for file changes and restart
fs.watch('./src', async () => {
console.log('🔄 Changes detected, restarting...');
await devServer.restart();
});
```
Given the vast array of features offered by `@push.rocks/smartshell`, integrating shell operations into your TypeScript applications becomes both straightforward and powerful. By harnessing promises and async/await syntax, `smartshell` effectively streamlines shell interactions, making your code cleaner and more intuitive.
### Docker Compose Helper
```typescript
const shell = new Smartshell({ executor: 'bash' });
// Start services and wait for readiness
console.log('🐳 Starting Docker services...');
await shell.execAndWaitForLine(
'docker-compose up',
/All services are ready/,
{ timeout: 60000 }
);
// Run migrations
await shell.execStrict('docker-compose exec app npm run migrate');
console.log('✅ Environment ready!');
```
### CI/CD Integration
```typescript
const shell = new Smartshell({ executor: 'bash' });
async function runCIPipeline() {
// Install dependencies
await shell.execStrict('pnpm install --frozen-lockfile');
// Run linting
const lintResult = await shell.execSilent('npm run lint');
if (lintResult.exitCode !== 0) {
throw new Error(`Linting failed:
${lintResult.stdout}`);
}
// Run tests with coverage
const testResult = await shell.exec('npm run test:coverage');
// Build project
await shell.execStrict('npm run build');
// Deploy if on main branch
if (process.env.BRANCH === 'main') {
await shell.execStrict('npm run deploy');
}
}
```
## API Reference 📚
### Smartshell Class
| Method | Description | Returns |
|--------|-------------|---------|
| `exec(command)` | Execute command with output | `Promise<IExecResult>` |
| `execSilent(command)` | Execute without console output | `Promise<IExecResult>` |
| `execStrict(command)` | Execute, throw on failure | `Promise<IExecResult>` |
| `execStrictSilent(command)` | Strict + silent execution | `Promise<IExecResult>` |
| `execStreaming(command)` | Stream output in real-time | `Promise<IExecResultStreaming>` |
| `execStreamingSilent(command)` | Stream without console output | `Promise<IExecResultStreaming>` |
| `execInteractive(command)` | Interactive terminal mode | `Promise<void>` |
| `execAndWaitForLine(command, regex)` | Wait for pattern match | `Promise<void>` |
| `execAndWaitForLineSilent(command, regex)` | Silent pattern waiting | `Promise<void>` |
### Result Interfaces
```typescript
interface IExecResult {
exitCode: number; // Process exit code
stdout: string; // Standard output
}
interface IExecResultStreaming {
childProcess: ChildProcess; // Node.js ChildProcess instance
finalPromise: Promise<void>; // Resolves when process exits
}
```
## Understanding Silent Modes 🤫
Silent execution modes are perfect when you need to capture command output for processing without cluttering the console. Here's what you need to know:
### How Silent Modes Work
1. **Output is captured, not lost**: All stdout content is stored in the result object
2. **Console stays clean**: Nothing is printed during execution
3. **Full programmatic access**: Process the output however you need
### Available Silent Methods
```typescript
// Basic silent execution
const result = await shell.execSilent('ls -la');
console.log(result.stdout); // Access captured output
console.log(result.exitCode); // Check success/failure
// Strict + Silent (throws on error)
try {
const result = await shell.execStrictSilent('important-command');
const output = result.stdout; // Process the output
} catch (error) {
// Handle failure
}
// Streaming + Silent
const streaming = await shell.execStreamingSilent('long-running-process');
streaming.childProcess.stdout.on('data', (chunk) => {
// Process chunks as they arrive
const data = chunk.toString();
});
// Pattern matching + Silent
await shell.execAndWaitForLineSilent('server-start', /Ready on port/);
```
### Common Use Cases for Silent Execution
```typescript
// Parse JSON output
const jsonResult = await shell.execSilent('aws s3 ls --output json');
const buckets = JSON.parse(jsonResult.stdout);
// Count lines
const wcResult = await shell.execSilent('wc -l huge-file.txt');
const lineCount = parseInt(wcResult.stdout.split(' ')[0]);
// Check if command exists
const whichResult = await shell.execSilent('which docker');
const dockerPath = whichResult.exitCode === 0 ? whichResult.stdout.trim() : null;
// Collect system info
const unameResult = await shell.execSilent('uname -a');
const systemInfo = unameResult.stdout.trim();
```
## Tips & Best Practices 💎
1. **Choose the right executor**: Use `bash` for full features, `sh` for minimal overhead
2. **Use strict mode for critical operations**: Ensures failures don't go unnoticed
3. **Stream long-running processes**: Better UX and memory efficiency
4. **Leverage silent modes**: When you only need to capture output
5. **Handle errors gracefully**: Always wrap strict executions in try-catch
6. **Clean up resources**: Streaming processes should be properly terminated

import { SmartExecution } from '@push.rocks/smartshell';
const execution = new SmartExecution(shell, 'npm run watch');
// Restart the process whenever needed
await execution.restart();
// Access the current streaming execution
if (execution.currentStreamingExecution) {
execution.currentStreamingExecution.childProcess.stdout.on('data', (data) => {
console.log(data.toString());
});
}
```
### Shell Detection
Need to check if a command exists? We export the `which` utility:
```typescript
import { which } from '@push.rocks/smartshell';
try {
const gitPath = await which('git');
console.log(`Git found at: ${gitPath}`);
} catch (error) {
console.log('Git is not installed');
}
```
## Real-World Examples 🌍
### Build Pipeline
```typescript
const shell = new Smartshell({ executor: 'bash' });
// Clean build directory
await shell.execSilent('rm -rf dist');
// Run TypeScript compiler
const buildResult = await shell.execStrict('tsc');
// Run tests
await shell.execStrict('npm test');
// Build succeeded!
console.log('✅ Build pipeline completed successfully');
```
### Development Server with Auto-Restart
```typescript
const shell = new Smartshell({ executor: 'bash' });
const devServer = new SmartExecution(shell, 'npm run dev');
// Watch for file changes and restart
fs.watch('./src', async () => {
console.log('🔄 Changes detected, restarting...');
await devServer.restart();
});
```
### Docker Compose Helper
```typescript
const shell = new Smartshell({ executor: 'bash' });
// Start services and wait for readiness
console.log('🐳 Starting Docker services...');
await shell.execAndWaitForLine(
'docker-compose up',
/All services are ready/,
{ timeout: 60000 }
);
// Run migrations
await shell.execStrict('docker-compose exec app npm run migrate');
console.log('✅ Environment ready!');
```
### CI/CD Integration
```typescript
const shell = new Smartshell({ executor: 'bash' });
async function runCIPipeline() {
// Install dependencies
await shell.execStrict('pnpm install --frozen-lockfile');
// Run linting
const lintResult = await shell.execSilent('npm run lint');
if (lintResult.exitCode !== 0) {
throw new Error(`Linting failed:
${lintResult.stdout}`);
}
// Run tests with coverage
const testResult = await shell.exec('npm run test:coverage');
// Build project
await shell.execStrict('npm run build');
// Deploy if on main branch
if (process.env.BRANCH === 'main') {
await shell.execStrict('npm run deploy');
}
}
```
## API Reference 📚
### Smartshell Class
| Method | Description | Returns |
|--------|-------------|---------|
| `exec(command)` | Execute command with output | `Promise<IExecResult>` |
| `execSilent(command)` | Execute without console output | `Promise<IExecResult>` |
| `execStrict(command)` | Execute, throw on failure | `Promise<IExecResult>` |
| `execStrictSilent(command)` | Strict + silent execution | `Promise<IExecResult>` |
| `execStreaming(command)` | Stream output in real-time | `Promise<IExecResultStreaming>` |
| `execStreamingSilent(command)` | Stream without console output | `Promise<IExecResultStreaming>` |
| `execInteractive(command)` | Interactive terminal mode | `Promise<void>` |
| `execAndWaitForLine(command, regex)` | Wait for pattern match | `Promise<void>` |
| `execAndWaitForLineSilent(command, regex)` | Silent pattern waiting | `Promise<void>` |
### Result Interfaces
```typescript
interface IExecResult {
exitCode: number; // Process exit code
stdout: string; // Standard output
}
interface IExecResultStreaming {
childProcess: ChildProcess; // Node.js ChildProcess instance
finalPromise: Promise<void>; // Resolves when process exits
}
```
## Understanding Silent Modes 🤫
Silent execution modes are perfect when you need to capture command output for processing without cluttering the console. Here's what you need to know:
### How Silent Modes Work
1. **Output is captured, not lost**: All stdout content is stored in the result object
2. **Console stays clean**: Nothing is printed during execution
3. **Full programmatic access**: Process the output however you need
### Available Silent Methods
```typescript
// Basic silent execution
const result = await shell.execSilent('ls -la');
console.log(result.stdout); // Access captured output
console.log(result.exitCode); // Check success/failure
// Strict + Silent (throws on error)
try {
const result = await shell.execStrictSilent('important-command');
const output = result.stdout; // Process the output
} catch (error) {
// Handle failure
}
// Streaming + Silent
const streaming = await shell.execStreamingSilent('long-running-process');
streaming.childProcess.stdout.on('data', (chunk) => {
// Process chunks as they arrive
const data = chunk.toString();
});
// Pattern matching + Silent
await shell.execAndWaitForLineSilent('server-start', /Ready on port/);
```
### Common Use Cases for Silent Execution
```typescript
// Parse JSON output
const jsonResult = await shell.execSilent('aws s3 ls --output json');
const buckets = JSON.parse(jsonResult.stdout);
// Count lines
const wcResult = await shell.execSilent('wc -l huge-file.txt');
const lineCount = parseInt(wcResult.stdout.split(' ')[0]);
// Check if command exists
const whichResult = await shell.execSilent('which docker');
const dockerPath = whichResult.exitCode === 0 ? whichResult.stdout.trim() : null;
// Collect system info
const unameResult = await shell.execSilent('uname -a');
const systemInfo = unameResult.stdout.trim();
```
## Tips & Best Practices 💎
1. **Choose the right executor**: Use `bash` for full features, `sh` for minimal overhead
2. **Use strict mode for critical operations**: Ensures failures don't go unnoticed
3. **Stream long-running processes**: Better UX and memory efficiency
4. **Leverage silent modes**: When you only need to capture output
5. **Handle errors gracefully**: Always wrap strict executions in try-catch
6. **Clean up resources**: Streaming processes should be properly terminated
