🚀 Quick Start

Installation

npm install alvamind-workflow

Simple Example (YAML)

1. Create workflow.yml:

version: "1.0"
name: "Deploy Application"
commands:
  - name: "Build Project"
    command: "npm run build"
  - name: "Run Tests"
    command: "npm test"
    skippable: true
  - name: "Deploy"
    command: "npm run deploy"

2. Run it:

workflow-run

Programmatic Usage

import { createWorkflow } from 'alvamind-workflow';

const workflow = createWorkflow({ name: 'CI Pipeline' })
  .execute('npm run lint', 'Lint Code')
  .execute('npm run test', 'Run Tests', true)
  .execute('npm run build', 'Build Project');

await workflow.run();

📊 Example Output

🐳 Executing workflow: Deploy Application
=====================================
Step 1/3: Build Project
> npm run build
 -> running... 2.5s
[1/3] ✓ Build Project 2.5s

Step 2/3: Run Tests
> npm test
 -> running... 1.2s
[2/3] ✓ Run Tests 1.2s

Step 3/3: Deploy
> npm run deploy
 -> running... 3.1s
[3/3] ✓ Deploy 3.1s
=====================================
✓ Workflow completed in 6.8s

🎛️ Advanced Features

Error Handling

try {
  await workflow
    .execute('risky-command', 'Risky Step', true) // skippable
    .execute('must-run', 'Critical Step')         // will fail if error
    .run();
} catch (error) {
  console.error('Workflow failed:', error);
}

Test Mode

await workflow.run({ testMode: true }); // Dry run without executing commands

Interactive Mode

When a command fails, the interactive mode provides options to:

1. Retry the original command
2. Enter a new command to execute
3. Skip the current step (if skippable)
4. Abort the entire workflow

🔧 API Reference

loadWorkflow(path?: string)

Loads a workflow configuration from a YAML file.

• path: (optional) Path to the YAML file. Defaults to workflow.yml.
• Returns: Promise<WorkflowConfig>

runWorkflow(config: WorkflowConfig, options?: RunnerOptions)

Executes a workflow based on the provided configuration.

• config: Workflow configuration object.
• options: (optional) Runner options.
  • testMode: (boolean) Enable test mode to prevent actual command execution.
• Returns: Promise<boolean>

createWorkflow(options?: WorkflowOptions)

Creates a new programmatic workflow builder.

• options: (optional) Workflow options.
  • name: (string) Workflow name.
• Returns: WorkflowBuilder

WorkflowBuilder

A fluent interface for constructing workflows programmatically.

• name(name: string): Sets the workflow name.
• execute(command: string, name: string, skippable?: boolean): Adds a command to the workflow.
• executeWith(command: string, name: string, callback: (result: { exitCode: number, stdout: string, stderr: string }) => string | undefined, skippable?: boolean): Adds a command with a callback (for branching logic).
• build(): Builds the workflow configuration object (WorkflowConfig).
• run(options?: WorkflowOptions): Runs the workflow.

Workflow Configuration (WorkflowConfig)

interface WorkflowConfig {
  version: string;
  name: string;
  commands: WorkflowCommand[];
}

Workflow Command (WorkflowCommand)

interface WorkflowCommand {
  command: string;
  name: string;
  skippable?: boolean;
}
