```bash
npm install @push.rocks/smartscaf --save
# Install globally for CLI usage
npm install -g @push.rocks/smartscaf
# Or add to your project
npm install @push.rocks/smartscaf --save-dev
```
## Usage
## Quick Start
Smartscaf provides a streamlined approach to quickly scaffold projects with predefined templates. It leverages modern TypeScript and ESM syntax to offer a flexible and powerful toolchain for project initialization. This guide will walk you through utilizing Smartscaf to its full potential, including setting up templates, customizing scaffolding processes, and programmatically controlling scaffolding operations.
### Create Your First Template
### Setting Up Your First Template
1. **Set up a template directory** with your project structure:
A Smartscaf template is essentially a directory with a set of files that you want to reuse across projects. It can include source code files, configuration files, and a special `.smartscaf.yml` file for defining template variables and dependencies.
```
my-template/
├── .smartscaf.yml # Template configuration
├── package.json # With {{projectName}} variables
├── src/
│ └── index.ts # Your source files
├── readme.md # With {{description}} placeholder
└── .gitignore # Standard ignores
```
1. **Create a Template Directory**: This directory should contain all the files and folders representing your template.
2. **Configure your template** in `.smartscaf.yml`:
2. **Define Template Variables in `.smartscaf.yml`**: This YAML file contains metadata about your template, such as default values for variables, dependency templates to merge, and scripts to run after scaffolding. Here's a basic example:
```yml
```yaml
# Template defaults and configuration
defaults:
projectName: 'My Awesome Project'
projectName: 'my-awesome-project'
description: 'A fantastic new project'
author: '{{gitName}}'
license: 'MIT'
nodeVersion: '20'
# Merge other templates (optional)
dependencies:
merge: []
merge:
- ../shared-config-template
- ../company-standards-template
# Post-scaffold automation
runafter:
- 'npm install'
- 'git init'
- 'git add .'
- 'git commit -m "Initial commit from SmartScaf"'
```
3. **Utilize Handlebars Syntax for Dynamic Content**: Files in your template can use the Handlebars syntax (`{{variableName}}`) for dynamic content that will be replaced during the scaffolding process.
3. **Use Handlebars syntax** in your template files:
### Scaffolding a New Project
```typescript
// src/index.ts
/**
* {{description}}
* @author {{author}}
* @license {{license}}
*/
Once you have a template ready, you can scaffold a new project by programmatically creating and manipulating a `ScafTemplate` instance from Smartscaf.
export class {{className}} {
constructor() {
console.log('Welcome to {{projectName}}!');
}
}
```
1. **Import Smartscaf and Create a New Instance**:
### Scaffold a New Project
```typescript
import { ScafTemplate } from '@push.rocks/smartscaf';
async function scaffoldProject() {
const myTemplate = await ScafTemplate.createTemplateFromDir(
'<path-to-your-template>',
);
await myTemplate.readTemplateFromDir(); // Load the template
// Supply any additional variables or override defaults
await myTemplate.supplyVariables({
projectName: 'My New Project',
async function createProject() {
// Load your template
const template = await ScafTemplate.createTemplateFromDir('./my-template');
await template.readTemplateFromDir();
// Supply variables (overrides defaults)
await template.supplyVariables({
projectName: 'super-api',
description: 'Revolutionary API service',
className: 'SuperAPI',
author: 'John Doe'
});
// Optionally, interactively ask for missing variables
// await myTemplate.askCliForMissingVariables();
await myTemplate.writeToDisk('<destination-path>'); // Scaffold!
// Interactive mode - asks for any missing variables
await template.askCliForMissingVariables();
// Generate the project
await template.writeToDisk('./projects/super-api');
console.log('✨ Project scaffolded successfully!');
}
scaffoldProject().then(() =>
console.log('Project scaffolded successfully!'),
);
createProject();
```
2. **Customizing the Scaffolding Process**: You can customize the scaffolding process by defining additional logic to manipulate files, directories, or template variables before writing to disk.
## Core Features
### Advanced Features
### 🎯 Smart Variable System
- **Merging Templates**: Smartscaf allows you to compose complex templates by specifying dependencies in the `.smartscaf.yml` file. This enables you to merge multiple templates into one scaffolded project.
- **Running Scripts After Scaffolding**: Specify an array of shell commands in the `runafter` section of your `.smartscaf.yml` to be executed after the project is scaffolded. This is useful for running installations or initial builds.
SmartScaf intelligently manages template variables through multiple layers:
- **Programmatic API**: Smartscaf's flexible API allows for programmatically controlling every aspect of the scaffolding process, making it suitable for integrating into build tools, command line utilities, or CI/CD pipelines.
```typescript
const template = await ScafTemplate.createTemplateFromDir('./template');
await template.readTemplateFromDir();
### Complete Feature Set and Use Cases
// Access variable collections
console.log(template.defaultVariables); // From .smartscaf.yml defaults
console.log(template.requiredVariables); // Found in template files
console.log(template.suppliedVariables); // What you've provided
console.log(template.missingVariables); // What still needs values
```
The usage scenarios outlined above merely scratch the surface of what Smartscaf can do. With its comprehensive API, you can manage complex scaffolding tasks, including but not limited to:
### 🔀 Template Composition
- Creating project templates with varying levels of complexity and customization.
- Dynamically adjusting project structures based on user input or external parameters.
- Integrating scaffolding steps into larger automation workflows, significantly reducing manual setup time for new projects.
Merge multiple templates to create complex project structures:
In conclusion, Smartscaf empowers developers to streamline their project initialization process, ensuring consistency, reducing boilerplate, and allowing more time to be spent on development rather than setup. Its flexibility and broad feature set make it a valuable tool in a modern developer's toolkit.
```yaml
# .smartscaf.yml
dependencies:
merge:
- ../base-template # Common structure
- ../auth-template # Authentication setup
- ../docker-template # Container configuration
```
For further information and a deeper dive into Smartscaf's capabilities, please refer to the [official documentation](https://gitlab.com/push.rocks/smartscaf#README) and explore the [source code](https://gitlab.com/push.rocks/smartscaf) for advanced use cases and customization options.
Templates are merged in order, allowing you to build sophisticated scaffolds from modular components.
### 📝 Dynamic File Naming
Use frontmatter to dynamically rename files during scaffolding:
```markdown
---
fileName: {{projectName}}.config.js
---
module.exports = {
name: '{{projectName}}',
version: '{{version}}'
};
```
### 🤖 Interactive CLI Mode
Let SmartScaf prompt for missing variables:
```typescript
// Automatically prompts for any variables not yet supplied
await template.askCliForMissingVariables();
```
### 🚀 Post-Scaffold Scripts
Automate setup tasks after scaffolding:
```yaml
runafter:
- 'npm install' # Install dependencies
- 'npm run build' # Initial build
- 'npm test' # Verify setup
- 'code .' # Open in VS Code
```
Scripts run in order using an interactive shell, ensuring proper environment handling.
## Advanced Usage
### Programmatic Control
```typescript
import { ScafTemplate } from '@push.rocks/smartscaf';
class ProjectGenerator {
private template: ScafTemplate;
async initialize(templatePath: string) {
this.template = await ScafTemplate.createTemplateFromDir(templatePath);
await this.template.readTemplateFromDir();
}
async generate(config: any, outputPath: string) {
// Supply configuration
await this.template.supplyVariables(config);
// Check what's missing
if (this.template.missingVariables.length > 0) {
console.log('Missing:', this.template.missingVariables);
// Handle missing variables programmatically
// or use: await this.template.askCliForMissingVariables();
}
// Generate project
await this.template.writeToDisk(outputPath);
}
}
```
### Template Validation
```typescript
// Validate template before using
const template = await ScafTemplate.createTemplateFromDir('./template');
await template.readTemplateFromDir();
// Check template structure
if (template.templateSmartfileArray.length === 0) {
throw new Error('Template is empty!');
}
// Verify required variables
const required = template.requiredVariables;
const defaults = Object.keys(template.defaultVariables);
const missing = required.filter(v => !defaults.includes(v));
if (missing.length > 0) {
console.warn(`Template needs: ${missing.join(', ')}`);
}
```
### Complex Variable Structures
SmartScaf supports nested object variables:
```yaml
# .smartscaf.yml
defaults:
app.name: 'MyApp'
app.version: '1.0.0'
database.host: 'localhost'
database.port: 5432
api.endpoints.users: '/api/users'
api.endpoints.auth: '/api/auth'
```
Use in templates:
```javascript
// config.js
export default {
app: {
name: '{{app.name}}',
version: '{{app.version}}'
},
database: {
host: '{{database.host}}',
port: {{database.port}}
},
api: {
users: '{{api.endpoints.users}}',
auth: '{{api.endpoints.auth}}'
}
};
```
### CI/CD Integration
```typescript
// ci-scaffold.ts
import { ScafTemplate } from '@push.rocks/smartscaf';
async function scaffoldForCI() {
const template = await ScafTemplate.createTemplateFromDir(
process.env.TEMPLATE_PATH
);
await template.readTemplateFromDir();
// Get variables from environment
const vars = {
projectName: process.env.PROJECT_NAME,
environment: process.env.DEPLOY_ENV,
apiKey: process.env.API_KEY,
region: process.env.AWS_REGION
};
await template.supplyVariables(vars);
await template.writeToDisk(process.env.OUTPUT_PATH);
}
// Run in CI pipeline
scaffoldForCI().catch(console.error);
```
## Real-World Examples
