# smartchok - Technical Hints
## Chokidar 4.x Migration (2024)
The module has been migrated from `@tempfix/watcher` to `chokidar` 4.x. Key changes:
### Dependencies
- **Removed**: `@tempfix/watcher` (a fork of fabiospampinato/watcher)
- **Added**: `chokidar` 4.x and `picomatch`
### Why picomatch?
Chokidar 4.x removed built-in glob pattern support. We use `picomatch` to maintain backward compatibility and provide glob pattern matching functionality.
### Implementation Details
1. **Glob pattern extraction**: The `getGlobBase()` method extracts base directories from glob patterns
2. **Pattern matching**: Each glob pattern is compiled to a picomatch matcher function
3. **Event filtering**: File system events are filtered based on glob patterns before being emitted
4. **Path normalization**: Paths are normalized to handle different formats (with/without leading ./)
### Event Handling
Chokidar 4.x events are mapped 1:1 with smartchok events:
- `add`, `change`, `unlink`: File events
- `addDir`, `unlinkDir`: Directory events
- `error`: Error events
- `raw`: Raw events from underlying watchers
- `ready`: Emitted when initial scan is complete
### Testing
All existing tests pass without modification, confirming backward compatibility is maintained.

```sh
npm install @push.rocks/smartchok --save
```
This command adds `@push.rocks/smartchok` to your project's dependencies, ensuring that your project can use its functionality and that it will be installed when running `npm install` in your project root.
## Usage
Use TypeScript for best in class instellisense.
The `@push.rocks/smartchok` package provides a convenient and smart wrapper around the popular `chokidar` library (v4.x) for file watching with enhanced features such as observable support for filesystem events and glob pattern matching support. This guide will introduce you to the usage of `@push.rocks/smartchok`, leveraging TypeScript for type safety and better developer experience.
```javascript
import { Smartchok } from 'smartchok';
### Setting Up Your Project
const mySmartChok = new Smartchok(['some/path/**/*.any', '/absolute/*.js'], chokidarOptions);
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:
mySmartChok.add(['/some/**/*.any']); // add files
mySmartChok.remove('some/**/*.js');
mySmartChok.start(); // starts the watch process
mySmartChok.getObservableFor('change').then((observableArg) => {
observableArg.subscribe((x) => {
// do something here when a change is detected
// possible events are 'add' | 'addDir' | 'change' | 'error' | 'unlink' | 'unlinkDir' | 'ready' | 'raw'
// note that the observable is only created once you call .start() on the Smartchok instance
// hence the promise construction
});
});
mySmartChok.stop();
```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.
## Contribution
### Basic Setup
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
To start using `smartchok`, first import it into your TypeScript file:
For further information read the linked docs at the top of this readme.
```typescript
import { Smartchok } from '@push.rocks/smartchok';
```

#### Initializing Smartchok
[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
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
]);
```
#### Adding and Removing Files Dynamically
You can dynamically add and remove paths from being watched by using the `add` and `remove` methods:
```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');
changeObservable.subscribe({
next: ([path, stats]) => {
console.log(`File changed: ${path}`);
},
error: (err) => {
console.error(`An error occurred: ${err}`);
}
});
```
Supported events include 'add', 'change', 'unlink' (for deletions), 'addDir', 'unlinkDir', 'error', 'ready', and 'raw'. Since chokidar 4.x no longer supports glob patterns natively, smartchok handles glob pattern matching internally using picomatch.
#### Stopping the Watcher
To stop watching for file changes, simply call:
```typescript
await smartchokInstance.stop();
```
### Advanced Usage
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.
### Conclusion
`@push.rocks/smartchok` provides a robust, observable-based wrapper around `chokidar` 4.x, 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. The package maintains backward compatibility by implementing glob pattern support that was removed in chokidar 4.x.
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.

# 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
