# Changelog
|
||||
|
||||
## 2025-11-30 - 3.0.0 - BREAKING CHANGE(smartwatch)
|
||||
Introduce Smartwatch: cross-runtime native file watching for Node.js, Deno and Bun; rename smartchok to smartwatch and bump major version to 2.0.0
|
||||
|
||||
- Rename public API and docs from Smartchok to Smartwatch and update package metadata for the new module name.
|
||||
- Replace chokidar with native watchers and picomatch-based glob filtering to enable cross-runtime support (Node.js, Deno, Bun).
|
||||
- Add watcher factory and runtime-specific implementations: watchers/index.ts, watcher.node.ts, watcher.deno.ts.
|
||||
- Add WriteStabilizer (ts/utils/write-stabilizer.ts) to provide awaitWriteFinish functionality via polling.
|
||||
- Introduce @push.rocks/smartenv for runtime detection and remove direct chokidar dependency; update dependencies accordingly.
|
||||
- Update tests (test/test.ts) and documentation (readme.md, readme.hints.md) to reflect API/name changes and new architecture.
|
||||
- Bump package version to 2.0.0 to mark breaking changes in API and behavior.
|
||||
|
||||
## 2025-11-29 - 1.2.0 - feat(core)
|
||||
Migrate to chokidar 5.x, add picomatch filtering and update test/dev dependencies
|
||||
|
||||
- Upgrade runtime dependencies: chokidar -> ^5.0.0 and picomatch -> ^4.0.3; bumped related @push.rocks packages versions.
|
||||
- Upgrade devDependencies: @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest to newer v2/v3 releases; updated @types/node.
|
||||
- Updated README and readme.hints to document migration to chokidar 5.x and dev dependency changes.
|
||||
- Tests updated to use @git.zone/tstest/tapbundle (import change) and test runner start changed to export default tap.start().
|
||||
- Smartchok implementation updated to extract glob base paths, watch base directories and filter events via picomatch matchers (shouldWatchPath + event filtering).
|
||||
- Note: ts/00_commitinfo_data.ts still references chokidar 4.x in the description and should be updated to reflect the migration.
|
||||
|
||||
## 2025-06-26 - 1.1.1 - fix(package.json)
|
||||
Add packageManager field to package.json for pnpm configuration

# smartchok - Technical Hints
|
||||
|
||||
## Native File Watching (v2.0.0+)
|
||||
|
||||
The module now uses native file watching APIs instead of chokidar, providing cross-runtime support for Node.js, Deno, and Bun.
|
||||
|
||||
### Architecture
|
||||
|
||||
```
|
||||
ts/
|
||||
├── smartwatch.classes.smartwatch.ts # Main Smartwatch class
|
||||
├── smartwatch.plugins.ts # Dependencies (smartenv, picomatch, etc.)
|
||||
├── watchers/
|
||||
│ ├── index.ts # Factory with runtime detection
|
||||
│ ├── interfaces.ts # IWatcher interface and types
|
||||
│ ├── watcher.node.ts # Node.js/Bun implementation (fs.watch)
|
||||
│ └── watcher.deno.ts # Deno implementation (Deno.watchFs)
|
||||
└── utils/
|
||||
└── write-stabilizer.ts # awaitWriteFinish polling implementation
|
||||
```
|
||||
|
||||
### Runtime Detection
|
||||
|
||||
Uses `@push.rocks/smartenv` v6.x for runtime detection:
|
||||
- **Node.js/Bun**: Uses native `fs.watch()` with `{ recursive: true }`
|
||||
- **Deno**: Uses `Deno.watchFs()` async iterable
|
||||
|
||||
### Dependencies
|
||||
|
||||
- **picomatch**: Glob pattern matching (zero deps, well-maintained)
|
||||
- **@push.rocks/smartenv**: Runtime detection (Node.js, Deno, Bun)
|
||||
- **@push.rocks/smartrx**: RxJS Subject/Observable management
|
||||
- **@push.rocks/smartpromise**: Deferred promise utilities
|
||||
- **@push.rocks/lik**: Stringmap for pattern storage
|
||||
|
||||
### Why picomatch?
|
||||
|
||||
Native file watching APIs don't support glob patterns. Picomatch provides glob pattern matching with:
|
||||
- Zero dependencies
|
||||
- 164M+ weekly downloads
|
||||
- Excellent security profile
|
||||
- Full glob syntax support
|
||||
|
||||
### Event Handling
|
||||
|
||||
Native events are normalized to a consistent interface:
|
||||
|
||||
| Node.js/Bun Event | Deno Event | Normalized Event |
|
||||
|-------------------|------------|------------------|
|
||||
| `rename` (file exists) | `create` | `add` |
|
||||
| `rename` (file gone) | `remove` | `unlink` |
|
||||
| `change` | `modify` | `change` |
|
||||
|
||||
### awaitWriteFinish Implementation
|
||||
|
||||
The `WriteStabilizer` class replaces chokidar's built-in write stabilization:
|
||||
- Polls file size until stable (configurable threshold: 300ms default)
|
||||
- Configurable poll interval (100ms default)
|
||||
- Handles file deletion during write detection
|
||||
|
||||
### Platform Requirements
|
||||
|
||||
- **Node.js 20+**: Required for native recursive watching on all platforms
|
||||
- **Deno**: Works on all versions with `Deno.watchFs()`
|
||||
- **Bun**: Uses Node.js compatibility layer
|
||||
|
||||
### Testing
|
||||
|
||||
```bash
|
||||
pnpm test
|
||||
```
|
||||
|
||||
Tests verify:
|
||||
- Creating Smartwatch instance
|
||||
- Adding glob patterns
|
||||
- Receiving 'add' events for new files
|
||||
- Graceful shutdown
|
||||
|
||||
## Dev Dependencies
|
||||
|
||||
- Using `@git.zone/tstest` v3.x with tapbundle
|
||||
- Import from `@git.zone/tstest/tapbundle`

## Usage
|
||||
|
||||
The `@push.rocks/smartchok` package provides a convenient and smart wrapper around the popular `chokidar` library for file watching with enhanced features such as observable support for filesystem events. This guide will introduce you to the usage of `@push.rocks/smartchok`, leveraging TypeScript for type safety and better developer experience.
|
||||
|
||||
### Setting Up Your Project
|
||||
|
||||
To use `@push.rocks/smartchok`, ensure your project is set up to use TypeScript and ECMAScript modules (ESM). You need to have a `tsconfig.json` file at the root of your project with the following minimum settings:
|
||||
|
||||
```json
|
||||
{
|
||||
"compilerOptions": {
|
||||
"target": "esnext",
|
||||
"module": "esnext",
|
||||
"moduleResolution": "node",
|
||||
"esModuleInterop": true,
|
||||
"declaration": true,
|
||||
"outDir": "./dist",
|
||||
"strict": true
|
||||
},
|
||||
"include": ["src/**/*"],
|
||||
"exclude": ["node_modules", "dist"]
|
||||
}
|
||||
```
|
||||
|
||||
This configuration enables TypeScript compilation targeting the latest ECMAScript standards and includes all TypeScript files (`*.ts`) in your `src` directory.
|
||||
|
||||
### Basic Setup
|
||||
|
||||
To start using `smartchok`, first import it into your TypeScript file:
|
||||
|
||||
```typescript
|
||||
import { Smartchok } from '@push.rocks/smartchok';
|
||||
```
|
||||
import { Smartwatch } from '@push.rocks/smartwatch';
|
||||
|
||||
#### Initializing Smartchok
|
||||
|
||||
Create an instance of `Smartchok` by specifying an array of glob patterns to watch:
|
||||
|
||||
```typescript
|
||||
const smartchokInstance = new Smartchok([
|
||||
'./src/**/*.ts', // Watch all TypeScript files in the src directory
|
||||
'./public/assets/**/*' // Watch all files in the public/assets directory
|
||||
// Create a watcher with glob patterns
|
||||
const watcher = new Smartwatch([
|
||||
'./src/**/*.ts', // Watch all TypeScript files in src
|
||||
'./public/assets/**/*' // Watch all files in public/assets
|
||||
]);
|
||||
|
||||
// Start watching
|
||||
await watcher.start();
|
||||
```
|
||||
|
||||
#### Adding and Removing Files Dynamically
|
||||
### Subscribing to File Events
|
||||
|
||||
You can dynamically add and remove paths from being watched by using the `add` and `remove` methods:
|
||||
Use RxJS observables to react to file system changes:
|
||||
|
||||
```typescript
|
||||
// Add additional files or patterns
|
||||
smartchokInstance.add(['./tests/**/*.spec.ts']);
|
||||
|
||||
// Remove specific patterns from watch
|
||||
smartchokInstance.remove('./src/**/*.test.ts');
|
||||
```
|
||||
|
||||
#### Handling Filesystem Events
|
||||
|
||||
`smartchok` leverages RxJS observables to notify about filesystem events. This allows you to respond to various events such as file additions, changes, and deletions with ease.
|
||||
|
||||
First, start the watcher:
|
||||
|
||||
```typescript
|
||||
await smartchokInstance.start();
|
||||
```
|
||||
|
||||
Then, subscribe to an event:
|
||||
|
||||
```typescript
|
||||
const changeObservable = await smartchokInstance.getObservableFor('change');
|
||||
// Get an observable for file changes
|
||||
const changeObservable = await watcher.getObservableFor('change');
|
||||
|
||||
changeObservable.subscribe({
|
||||
next: ([path, stats]) => {
|
||||
console.log(`File changed: ${path}`);
|
||||
},
|
||||
error: (err) => {
|
||||
console.error(`An error occurred: ${err}`);
|
||||
console.error(`Error: ${err}`);
|
||||
}
|
||||
});
|
||||
|
||||
// Watch for new files
|
||||
const addObservable = await watcher.getObservableFor('add');
|
||||
addObservable.subscribe(([path]) => {
|
||||
console.log(`File added: ${path}`);
|
||||
});
|
||||
|
||||
// Watch for deleted files
|
||||
const unlinkObservable = await watcher.getObservableFor('unlink');
|
||||
unlinkObservable.subscribe(([path]) => {
|
||||
console.log(`File deleted: ${path}`);
|
||||
});
|
||||
```
|
||||
|
||||
Supported events include 'add', 'change', 'unlink' (for deletions), and others. Refer to the chokidar documentation for a full list of events.
|
||||
### Supported Events

|
||||
| Event | Description |
|
||||
|-------|-------------|
|
||||
| `add` | File has been added |
|
||||
| `addDir` | Directory has been added |
|
||||
| `change` | File has been changed |
|
||||
| `unlink` | File has been removed |
|
||||
| `unlinkDir` | Directory has been removed |
|
||||
| `error` | Error occurred |
|
||||
| `ready` | Initial scan complete |
|
||||
| `raw` | Raw event from the underlying watcher |
|
||||
|
||||
To stop watching for file changes, simply call:
|
||||
### Dynamic Watch Management
|
||||
|
||||
Add or remove patterns while the watcher is running:
|
||||
|
||||
```typescript
|
||||
await smartchokInstance.stop();
|
||||
const watcher = new Smartwatch(['./src/**/*.ts']);
|
||||
await watcher.start();
|
||||
|
||||
// Add more patterns to watch
|
||||
watcher.add(['./tests/**/*.spec.ts', './config/*.json']);
|
||||
|
||||
// Remove a pattern
|
||||
watcher.remove('./src/**/*.test.ts');
|
||||
```
|
||||
|
||||
### Advanced Usage
|
||||
### Stopping the Watcher
|
||||
|
||||
Beyond the basics, `smartchok` allows for more complex monitoring scenarios, such as debounced notifications for rapid changes, filtering events, and integrating with other observables for complex asynchronous workflows.
|
||||
```typescript
|
||||
// Stop watching when done
|
||||
await watcher.stop();
|
||||
```
|
||||
|
||||
### Conclusion
|
||||
### Complete Example
|
||||
|
||||
`@push.rocks/smartchok` provides a robust, observable-based wrapper around `chokidar`, making it an excellent choice for projects requiring efficient and flexible file monitoring. Its integration with RxJS opens up a wide array of possibilities for handling file system events in a reactive manner, making your code more concise, readable, and maintainable.
|
||||
```typescript
|
||||
import { Smartwatch } from '@push.rocks/smartwatch';
|
||||
|
||||
By following the guidelines provided in this document, you should now be equipped to integrate `@push.rocks/smartchok` into your TypeScript project, enhancing its capabilities with efficient file system monitoring.
|
||||
async function watchProject() {
|
||||
// Initialize with patterns
|
||||
const watcher = new Smartwatch([
|
||||
'./src/**/*.ts',
|
||||
'./package.json'
|
||||
]);
|
||||
|
||||
// Start the watcher
|
||||
await watcher.start();
|
||||
console.log('👀 Watching for changes...');
|
||||
|
||||
// Subscribe to changes
|
||||
const changes = await watcher.getObservableFor('change');
|
||||
changes.subscribe(([path, stats]) => {
|
||||
console.log(`📝 Modified: ${path}`);
|
||||
console.log(` Size: ${stats?.size ?? 'unknown'} bytes`);
|
||||
});
|
||||
|
||||
// Subscribe to new files
|
||||
const additions = await watcher.getObservableFor('add');
|
||||
additions.subscribe(([path]) => {
|
||||
console.log(`✨ New file: ${path}`);
|
||||
});
|
||||
|
||||
// Subscribe to deletions
|
||||
const deletions = await watcher.getObservableFor('unlink');
|
||||
deletions.subscribe(([path]) => {
|
||||
console.log(`🗑️ Deleted: ${path}`);
|
||||
});
|
||||
|
||||
// Handle graceful shutdown
|
||||
process.on('SIGINT', async () => {
|
||||
console.log('\n🛑 Stopping watcher...');
|
||||
await watcher.stop();
|
||||
process.exit(0);
|
||||
});
|
||||
}
|
||||
|
||||
watchProject();
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
Since chokidar 4.x+ no longer supports glob patterns natively, smartwatch handles glob pattern matching internally using [picomatch](https://github.com/micromatch/picomatch). This means you get the familiar glob syntax while benefiting from chokidar's efficient file watching capabilities.
|
||||
|
||||
When you provide glob patterns:
|
||||
1. **Base path extraction** - smartwatch extracts the static base path from each pattern
|
||||
2. **Efficient watching** - chokidar watches the base directories
|
||||
3. **Pattern filtering** - Events are filtered through picomatch matchers before being emitted
|
||||
|
||||
## API Reference
|
||||
|
||||
### `Smartwatch`
|
||||
|
||||
#### Constructor
|
||||
|
||||
```typescript
|
||||
new Smartwatch(patterns: string[])
|
||||
```
|
||||
|
||||
Creates a new Smartwatch instance with the given glob patterns.
|
||||
|
||||
#### Methods
|
||||
|
||||
| Method | Returns | Description |
|
||||
|--------|---------|-------------|
|
||||
| `start()` | `Promise<void>` | Starts watching for file changes |
|
||||
| `stop()` | `Promise<void>` | Stops the file watcher |
|
||||
| `add(patterns: string[])` | `void` | Adds patterns to watch |
|
||||
| `remove(pattern: string)` | `void` | Removes a pattern from watching |
|
||||
| `getObservableFor(event: TFsEvent)` | `Promise<Observable<[string, Stats]>>` | Returns an RxJS observable for the specified event |
|
||||
|
||||
#### Properties
|
||||
|
||||
| Property | Type | Description |
|
||||
|----------|------|-------------|
|
||||

# Migration Plan: smartchok to Chokidar 4.x
|
||||
|
||||
Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
|
||||
|
||||
## MIGRATION COMPLETED ✅
|
||||
|
||||
All phases of the migration have been successfully completed:
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
- **Current dependency**: `@tempfix/watcher` v2.3.0 (a fork of fabiospampinato/watcher)
|
||||
- **Target**: Chokidar v4.0.3
|
||||
- **Major challenge**: Chokidar 4.x removed glob support, but smartchok heavily uses glob patterns
|
||||
|
||||
## Migration Plan
|
||||
|
||||
### Phase 1: Preparation
|
||||
1. Install chokidar 4.x and glob library for pattern matching
|
||||
- `pnpm install chokidar@^4.0.3`
|
||||
- `pnpm install picomatch` (for glob pattern matching)
|
||||
- `pnpm uninstall @tempfix/watcher`
|
||||
|
||||
### Phase 2: Code Changes
|
||||
|
||||
#### 2.1 Update Plugin Imports (ts/smartchok.plugins.ts)
|
||||
- Remove `@tempfix/watcher` import
|
||||
- Add `chokidar` import
|
||||
- Add `picomatch` for glob pattern matching
|
||||
|
||||
#### 2.2 Update Smartchok Class (ts/smartchok.classes.smartchok.ts)
|
||||
- Replace watcher initialization with chokidar
|
||||
- Implement custom glob filtering using picomatch
|
||||
- Update event mapping to match chokidar's event names
|
||||
- Adjust watcher options to match chokidar's API
|
||||
|
||||
#### 2.3 Handle Glob Patterns
|
||||
Since chokidar 4.x removed glob support, we need to:
|
||||
- Parse glob patterns to extract base directories
|
||||
- Use chokidar to watch base directories
|
||||
- Use picomatch to filter events based on glob patterns
|
||||
- Ensure backward compatibility with existing API
|
||||
|
||||
#### 2.4 Event Mapping
|
||||
Map chokidar events to existing smartchok events:
|
||||
- Keep existing event names for backward compatibility
|
||||
- Ensure all current functionality is preserved
|
||||
|
||||
### Phase 3: Testing
|
||||
1. Run existing tests to ensure backward compatibility
|
||||
2. Add new tests for glob pattern handling
|
||||
3. Test edge cases with complex glob patterns
|
||||
4. Verify performance with large file sets
|
||||
|
||||
### Phase 4: Documentation
|
||||
1. Update readme.md to reflect the change to chokidar 4.x
|
||||
2. Document any API changes (if any)
|
||||
3. Update version number in package.json
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Key Differences to Handle:
|
||||
1. **Glob Support**: Implement custom glob filtering layer
|
||||
2. **API Changes**: Adapt initialization and option passing
|
||||
3. **Event Names**: Map between different event naming conventions
|
||||
4. **Minimum Node Version**: Ensure compatibility with Node 14+
|
||||
|
||||
### Risk Mitigation:
|
||||
- Maintain backward compatibility with existing API
|
||||
- Extensive testing with current test suite
|
||||
- Consider keeping a legacy branch if breaking changes are unavoidable
