# Code Style and Conventions for TaskBuffer
## File Structure
- Source code in `ts/` directory
- Tests in `test/` directory
- Compiled output in `dist_ts/`
- All filenames must be lowercase
## Naming Conventions
- **Interfaces**: Prefix with `I` (e.g., `ITaskFunction`)
- **Types**: Prefix with `T` (e.g., `TPreOrAfterTaskFunction`)
- **Classes**: PascalCase (e.g., `TaskManager`)
- **Files**: `taskbuffer.classes.{classname}.ts` pattern
- **Test files**: `test.{number}.{feature}.ts` pattern
## TypeScript Conventions
- Use ES modules (import/export)
- Avoid ENums when possible
- Import dependencies through `plugins.ts`
- Reference with full path: `plugins.myModule.myClass()`
- Use async/await patterns consistently
- Strong typing throughout
## Testing Conventions
- Import expect from `@git.zone/tstest/tapbundle`
- Test files end with `export default tap.start()`
- Use descriptive test names with tap.test()
- Test both browser and node when applicable
## Code Quality
- Make focused, goal-oriented changes
- Preserve necessary complexity
- Keep code elegant and maintainable
- No inline documentation unless requested
- Complete implementations only (no partial work)

# TaskBuffer Project Overview
## Purpose
@push.rocks/taskbuffer is a powerful TypeScript-first task management library for orchestrating asynchronous operations. It provides flexible task execution patterns including buffered execution, task chains, parallel execution, scheduling, debouncing, and one-time execution.
## Tech Stack
- **Language**: TypeScript (ES modules)
- **Runtime**: Node.js
- **Build Tool**: tsbuild, tsbundle
- **Test Framework**: @git.zone/tstest (tapbundle)
- **Package Manager**: pnpm
- **Module System**: ES modules (type: "module")
## Key Features
- Task: Basic unit of work with async function wrapping
- Taskchain: Sequential task execution with result passing
- Taskparallel: Parallel task execution
- TaskManager: Cron-based task scheduling
- TaskDebounced: Debounced execution pattern
- TaskOnce: Singleton execution pattern
- TaskRunner: Distributed task execution
- BufferRunner: Smart concurrent execution control
## Main Entry Points
- Main export: `ts/index.ts`
- Compiled output: `dist_ts/index.js`
- All classes exported from index for clean API

# Task Completion Checklist for TaskBuffer
## Before Marking Any Task Complete
### 1. Code Quality Checks
- [ ] Run build to ensure TypeScript compiles: `pnpm run build`
- [ ] Run tests to ensure nothing breaks: `pnpm test`
- [ ] Type check test files: `tsbuild check test/**/* --skiplibcheck`
### 2. Code Review
- [ ] All changes are focused and purposeful
- [ ] No unnecessary modifications made
- [ ] Code follows project naming conventions
- [ ] Imports use the plugins.ts pattern where applicable
- [ ] All async operations use proper async/await
### 3. Testing
- [ ] New features have corresponding tests
- [ ] Existing tests still pass
- [ ] Test files end with `export default tap.start()`
- [ ] Tests use proper expect from tapbundle
### 4. Documentation
- [ ] readme.md updated if new features added
- [ ] Code is self-explanatory (no comments unless requested)
- [ ] API changes documented
### 5. Git Hygiene
- [ ] Changes are staged appropriately
- [ ] Commit message is clear and focused
- [ ] NO commits made without explicit user approval
## Common Issues to Check
- No uppercase filenames
- No direct npm usage (use pnpm)
- No guessing APIs (always check documentation)
- No partial implementations

# Changelog
## 2025-09-07 - 3.4.0 - feat(taskbuffer-dashboard)
Add TaskBuffer dashboard web component, demo and browser tests; add HTML entry and update dependencies
- Introduce a new web component taskbuffer-dashboard for real-time visualization of tasks and schedules (ts_web/taskbuffer-dashboard.ts).
- Add a demo wrapper and interactive UI for the dashboard (ts_web/elements/taskbuffer-dashboard.demo.ts).
- Provide web exports and typings for web usage (ts_web/index.ts) and include an HTML entry (html/index.html).
- Add browser-oriented tests to validate metadata structures for the web component (test/test.10.webcomponent.browser.ts).
- Bump package version to 3.3.0 in package.json as part of this change.
- Update/add dependencies and devDependencies (@design.estate/dees-element added; smartlog, @git.zone/tsbuild and @git.zone/tstest bumped).
## 2025-09-06 - 3.2.0 - feat(core)
Add step-based progress tracking, task metadata and enhanced TaskManager scheduling/metadata APIs
- Introduce TaskStep class for named, weighted steps with timing and status (pending|active|completed).
- Add step-tracking to Task: notifyStep, getProgress, getStepsMetadata, getMetadata, resetSteps and internal step lifecycle handling.
- Task now records runCount and lastRun; Task.run flow resets/cleans steps and aggregates progress.
- TaskManager enhancements: schedule/deschedule improvements, performDistributedConsultation, and new metadata-focused APIs: getTaskMetadata, getAllTasksMetadata, getScheduledTasks, getNextScheduledRuns, addExecuteRemoveTask (exec + collect report).
- Exports updated: TaskStep and related types exported from index, plus Task metadata interfaces.
- Comprehensive README updates documenting step-based progress tracking, metadata, TaskManager and examples.
- New/updated tests added for step behavior and metadata (test/test.9.steps.ts) and other TS additions.
- Minor build/script change: build script updated to use 'tsbuild tsfolders'.
## 2025-08-26 - 3.1.10 - fix(task)
Implement core Task execution flow, buffering and lifecycle; update README with generics and buffer docs
- Implement Task.runTask including preTask/afterTask chaining, touched-task cycle prevention and error handling.
- Add Task helpers: extractTask, isTask, isTaskTouched and emptyTaskFunction (resolved promise).
- Introduce task lifecycle coordination: finished promise, resolveFinished, and blockingTasks to await dependent tasks.
- Support taskSetup/setupValue, execDelay handling, and wait-for-blocking-tasks before execution.

### Basic Task Creation
[![repo-footer](https://pushrocks.gitlab.io/assets/repo-footer.svg)](https://push.rocks)
```typescript
import { Task, TaskManager } from '@push.rocks/taskbuffer';
## Contribution
// Create a simple task
const dataProcessor = new Task({
name: 'ProcessData',
taskFunction: async (data) => {
console.log(`Processing: ${data}`);
// Your async logic here
return `Processed: ${data}`;
}
});
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). :)
// Execute the task
const result = await dataProcessor.trigger('my-data');
console.log(result); // "Processed: my-data"
```

this.notifyStep('test');
await runTests();
this.notifyStep('deploy');
await deployToServer();
this.notifyStep('verify');
await verifyDeployment();
return 'Deployment successful!';
}
});
// Monitor progress
console.log(deploymentTask.getProgress()); // 0-100
console.log(deploymentTask.getStepsMetadata()); // Detailed step info
```
## 🎯 Core Concepts
### Task Buffering - Intelligent Request Management
TaskBuffer's buffering system prevents overwhelming your system with rapid-fire requests:
```typescript
const apiTask = new Task({
name: 'APIRequest',
taskFunction: async (endpoint) => {
return await fetch(endpoint).then(r => r.json());
},
buffered: true,
bufferMax: 5, // Maximum 5 concurrent executions
execDelay: 100 // Minimum 100ms between executions
});
// Rapid fire 100 calls - only 5 will execute concurrently
for (let i = 0; i < 100; i++) {
apiTask.trigger(`/api/data/${i}`);
}
```
**Buffer Behavior:**
- First `bufferMax` calls execute immediately
- Additional calls are queued
- When buffer is full, new calls overwrite the last queued item
- Perfect for real-time data streams where only recent data matters
### Task Chains - Sequential Workflows
Build complex workflows with automatic data flow:
```typescript
import { Task, Taskchain } from '@push.rocks/taskbuffer';
const fetchTask = new Task({
name: 'FetchData',
taskFunction: async () => {
const response = await fetch('/api/data');
return response.json();
}
});
const transformTask = new Task({
name: 'TransformData',
taskFunction: async (data) => {
return data.map(item => ({
...item,
transformed: true,
timestamp: Date.now()
}));
}
});
const saveTask = new Task({
name: 'SaveData',
taskFunction: async (transformedData) => {
await database.save(transformedData);
return transformedData.length;
}
});
// Create and execute chain
const dataChain = new Taskchain({
name: 'DataPipeline',
tasks: [fetchTask, transformTask, saveTask]
});
const savedCount = await dataChain.trigger();
console.log(`Saved ${savedCount} items`);
```
### Parallel Execution - Concurrent Processing
Execute multiple tasks simultaneously:
```typescript
import { TaskParallel } from '@push.rocks/taskbuffer';
const parallel = new TaskParallel({
name: 'ParallelProcessor',
tasks: [
emailTask,
smsTask,
pushNotificationTask,
webhookTask
]
});
// All tasks execute concurrently
const results = await parallel.trigger(notificationData);
// results = [emailResult, smsResult, pushResult, webhookResult]
```
### TaskManager - Centralized Orchestration
Manage all your tasks from a single point:
```typescript
const taskManager = new TaskManager();
// Add tasks
taskManager.addTask(dataProcessor);
taskManager.addTask(deploymentTask);
// Schedule tasks with cron
taskManager.addAndScheduleTask(backupTask, '0 2 * * *'); // Daily at 2 AM
taskManager.addAndScheduleTask(healthCheck, '*/5 * * * *'); // Every 5 minutes
// Get task metadata
const metadata = taskManager.getTaskMetadata('DeployApplication');
console.log(metadata);
// {
// name: 'DeployApplication',
// status: 'idle' | 'running' | 'completed' | 'failed',
// steps: [...],
// currentProgress: 75,
// runCount: 12,
// lastRun: Date,
// buffered: false,
// bufferMax: undefined,
// version: '1.0.0',
// timeout: 30000
// }
// Get all scheduled tasks
const scheduled = taskManager.getScheduledTasks();
scheduled.forEach(task => {
console.log(`${task.name}: Next run at ${task.nextRun}`);
});
// Execute and remove pattern
const report = await taskManager.addExecuteRemoveTask(temporaryTask, {
trackProgress: true
});
console.log(report);
// {
// taskName: 'TempTask',
// startTime: Date,
// endTime: Date,
// duration: 1523,
// steps: [...],
// stepsCompleted: ['step1', 'step2'],
// progress: 100,
// result: any,
// error?: Error
// }
```
## 🎨 Web Component Dashboard
Visualize your tasks in real-time with the included web component:
```html
<!DOCTYPE html>
<html>
<head>
<script type="module">
import { TaskManager } from '@push.rocks/taskbuffer';
import '@push.rocks/taskbuffer/dist_ts_web/taskbuffer-dashboard.js';
const taskManager = new TaskManager();
// Attach to dashboard
const dashboard = document.querySelector('taskbuffer-dashboard');
dashboard.taskManager = taskManager;
dashboard.refreshInterval = 500; // Update every 500ms
</script>
</head>
<body>
<taskbuffer-dashboard></taskbuffer-dashboard>
</body>
</html>
```
The dashboard provides:
- 📊 Real-time progress bars with step indicators
- 📈 Task execution history
- ⏰ Scheduled task information
- 🎯 Interactive task controls
- 🌓 Light/dark theme support
## 🧩 Advanced Patterns
### Dynamic Task Routing
Route tasks based on conditions:
```typescript
const routerTask = new Task({
name: 'Router',
taskFunction: async (request) => {
if (request.priority === 'high') {
return await expressProcessor.trigger(request);
} else if (request.size > 1000000) {
return await bulkProcessor.trigger(request);
} else {
return await standardProcessor.trigger(request);
}
}
});
```
### Task Pools
Create reusable task pools for load distribution:
```typescript
class TaskPool {
private tasks: Task[] = [];
private currentIndex = 0;
constructor(poolSize: number, taskConfig: any) {
for (let i = 0; i < poolSize; i++) {
this.tasks.push(new Task({
...taskConfig,
name: `${taskConfig.name}_${i}`
}));
}
}
async execute(data: any) {
const task = this.tasks[this.currentIndex];
this.currentIndex = (this.currentIndex + 1) % this.tasks.length;
return await task.trigger(data);
}
}
const processorPool = new TaskPool(5, {
name: 'DataProcessor',
taskFunction: async (data) => processData(data)
});
```
### Error Recovery & Retry
Implement robust error handling:
```typescript
const resilientTask = new Task({
name: 'ResilientTask',
taskFunction: async (data, retryCount = 0) => {
try {
return await riskyOperation(data);
} catch (error) {
if (retryCount < 3) {
console.log(`Retry ${retryCount + 1}/3`);
await new Promise(r => setTimeout(r, 1000 * Math.pow(2, retryCount)));
return await resilientTask.trigger(data, retryCount + 1);
}
throw error;
}
}
});
```
### Task Composition
Compose complex behaviors from simple tasks:
```typescript
const compositeTask = new Task({
name: 'CompositeOperation',
steps: [
{ name: 'validate', description: 'Validating input', percentage: 20 },
{ name: 'process', description: 'Processing data', percentage: 60 },
{ name: 'notify', description: 'Sending notifications', percentage: 20 }
] as const,
taskFunction: async function(data) {
this.notifyStep('validate');
const validated = await validationTask.trigger(data);
this.notifyStep('process');
const processed = await processingTask.trigger(validated);
this.notifyStep('notify');
await notificationTask.trigger(processed);
return processed;
}
});
```
## 🔧 Configuration
### Task Options
```typescript
interface TaskOptions<T = undefined, TSteps = []> {
name?: string; // Task identifier
taskFunction: Function; // Async function to execute
buffered?: boolean; // Enable buffering
bufferMax?: number; // Max concurrent executions
execDelay?: number; // Min delay between executions
timeout?: number; // Task timeout in ms
version?: string; // Task version
steps?: TSteps; // Progress steps configuration
taskSetup?: Function; // One-time setup function
beforeTask?: Function; // Runs before each execution
afterTask?: Function; // Runs after each execution
}
```
### TaskManager Options
```typescript
const taskManager = new TaskManager({
maxConcurrentTasks: 10, // Global concurrency limit
defaultTimeout: 30000, // Default task timeout
logLevel: 'info' // Logging verbosity
});
```
## 📊 Monitoring & Observability
### Task Events
```typescript
task.on('started', () => console.log('Task started'));
task.on('completed', (result) => console.log('Task completed:', result));
task.on('failed', (error) => console.error('Task failed:', error));
task.on('stepChange', (step) => console.log('Step:', step.name));
```
### Execution Metrics
```typescript
const metrics = task.getMetrics();
console.log({
totalRuns: metrics.runCount,
averageDuration: metrics.avgDuration,
successRate: metrics.successRate,
lastError: metrics.lastError
});
```
## 🧪 Testing
```typescript
import { expect, tap } from '@git.zone/tstest';
import { Task } from '@push.rocks/taskbuffer';
tap.test('Task should execute with progress tracking', async () => {
const task = new Task({
name: 'TestTask',
steps: [
{ name: 'step1', description: 'Step 1', percentage: 50 },
{ name: 'step2', description: 'Step 2', percentage: 50 }
] as const,
taskFunction: async function() {
this.notifyStep('step1');
await new Promise(r => setTimeout(r, 100));
this.notifyStep('step2');
return 'done';
}
});
const result = await task.trigger();
expect(result).toEqual('done');
expect(task.getProgress()).toEqual(100);
});
```
## 🌐 Real-World Examples
### API Rate Limiter
```typescript
const apiLimiter = new Task({
name: 'APIRateLimiter',
buffered: true,
bufferMax: 10, // Max 10 requests per second
execDelay: 100, // 100ms between requests
taskFunction: async (endpoint, data) => {
return await fetch(endpoint, {
method: 'POST',
body: JSON.stringify(data)
});
}
});
```
### Database Migration Pipeline
```typescript
const migrationChain = new Taskchain({
name: 'DatabaseMigration',
tasks: [
backupDatabaseTask,
validateSchemaTask,
runMigrationsTask,
verifyIntegrityTask,
updateIndexesTask
]
});
// Execute with rollback on failure
try {
await migrationChain.trigger();
console.log('Migration successful!');
} catch (error) {
await rollbackTask.trigger();
throw error;
}
```
### Distributed Job Queue
```typescript
const jobQueue = new TaskManager();
// Worker tasks
const imageProcessor = new Task({
name: 'ImageProcessor',
buffered: true,
bufferMax: 5,
steps: [
{ name: 'download', description: 'Downloading', percentage: 20 },
{ name: 'resize', description: 'Resizing', percentage: 40 },
{ name: 'optimize', description: 'Optimizing', percentage: 30 },
{ name: 'upload', description: 'Uploading', percentage: 10 }
] as const,
taskFunction: async function(job) {
this.notifyStep('download');
const image = await downloadImage(job.url);
this.notifyStep('resize');
const resized = await resizeImage(image, job.dimensions);
this.notifyStep('optimize');
const optimized = await optimizeImage(resized);
this.notifyStep('upload');
return await uploadToCDN(optimized);
}
});
jobQueue.addTask(imageProcessor);
// Process incoming jobs
messageQueue.on('job', async (job) => {
const result = await jobQueue.getTaskByName('ImageProcessor').trigger(job);
await messageQueue.ack(job.id, result);
});
```
## 🚀 Performance Tips
1. **Use Buffering Wisely** - Enable buffering for I/O-bound tasks
2. **Set Appropriate Delays** - Use `execDelay` to prevent API rate limits
3. **Leverage Task Pools** - Distribute load across multiple task instances
4. **Monitor Progress** - Use step tracking for long-running operations
5. **Clean Up** - Use `addExecuteRemoveTask` for one-time operations
## 🔍 Debugging
Enable detailed logging:
```typescript
import { logger } from '@push.rocks/smartlog';
logger.enableConsole();
logger.level = 'debug';
// Tasks will now output detailed execution logs
```
## 📚 API Reference
### Core Classes
- **`Task<T, TSteps>`** - Basic task unit with optional step tracking
- **`TaskManager`** - Central orchestrator for task management
- **`Taskchain`** - Sequential task executor
- **`TaskParallel`** - Concurrent task executor
- **`TaskOnce`** - Single-execution task
- **`TaskLoop`** - Repeating task with conditions
### Key Methods
#### Task Methods
- `trigger(input?: T): Promise<any>` - Execute the task
- `notifyStep(stepName: StepNames<TSteps>): void` - Update current step
- `getProgress(): number` - Get progress percentage (0-100)
- `getStepsMetadata(): ITaskStep[]` - Get detailed step information
- `getMetadata(): ITaskMetadata` - Get complete task metadata
#### TaskManager Methods
- `addTask(task: Task): void` - Register a task
- `getTaskByName(name: string): Task | undefined` - Retrieve task by name
- `addAndScheduleTask(task: Task, cronExpression: string): void` - Schedule task
- `descheduleTaskByName(name: string): void` - Remove scheduling
- `getTaskMetadata(name: string): ITaskMetadata | null` - Get task metadata
- `getAllTasksMetadata(): ITaskMetadata[]` - Get all tasks metadata
- `getScheduledTasks(): IScheduledTaskInfo[]` - List scheduled tasks
- `addExecuteRemoveTask(task, options?): Promise<ITaskExecutionReport>` - Execute once
