# Changelog # 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.
- Wire up trigger() to choose buffered vs unbuffered execution (triggerBuffered / triggerUnBuffered) and integrate BufferRunner.
- Improve logging and safer promise handling (caught errors are logged).
- Update README with extended TypeScript generics examples and expanded buffer behavior and strategies documentation.
## 2025-08-26 - 3.1.9 - fix(tests)
Update CI workflows, fix tests and refresh README/package metadata
- CI: switch Docker image to code.foss.global/host.today/ht-docker-node:npmci and adjust NPMCI_COMPUTED_REPOURL; replace npmci installer package name from @shipzone/npmci to @ship.zone/npmci in Gitea workflows
- Tests: update test imports to use @git.zone/tstest/tapbundle and apply small formatting fixes to test files
- Package metadata: update bugs URL and homepage to code.foss.global, add a pnpm.overrides placeholder in package.json
- .gitignore: add AI/tooling directories (.claude, .serena) and reorganize custom section
- Code style/TS fixes: minor formatting changes across ts sources (trailing commas, line breaks, consistent object/argument commas) and small API surface formatting fixes
- Documentation: whitespace/formatting cleanups in README and add changelog entry for 3.1.8
## 2025-08-26 - 3.1.8 - fix(tests) ## 2025-08-26 - 3.1.8 - fix(tests)

## Why taskbuffer? 🤔 ## 🚀 Quick Start
In the modern JavaScript ecosystem, managing asynchronous tasks efficiently is crucial. Whether you're building a data pipeline, managing API rate limits, or orchestrating complex workflows, **@push.rocks/taskbuffer** provides the tools you need: ### Basic Task Creation
- **🎯 TypeScript-first**: Built with TypeScript for TypeScript - enjoy complete type safety and excellent IDE support
- **⚡ Flexible execution**: From simple tasks to complex parallel workflows with dependencies
- **🔄 Smart buffering**: Control concurrent executions with intelligent buffer management
- **⏰ Built-in scheduling**: Cron-based task scheduling without additional dependencies
- **🎭 Multiple paradigms**: Support for debounced, throttled, and one-time execution patterns
- **🔌 Extensible**: Clean architecture that's easy to extend and customize
- **🏃 Zero dependencies on external schedulers**: Everything you need is included
## Core Concepts 🎓
### Task
The fundamental unit of work. A task wraps an asynchronous function and provides powerful execution control.
### Taskchain
Sequential task execution - tasks run one after another, with results passed along the chain.
### Taskparallel
Parallel task execution - multiple tasks run simultaneously for maximum performance.
### TaskManager
Centralized task scheduling and management using cron expressions.
### TaskDebounced
Debounced task execution - prevents rapid repeated executions, only running after a quiet period.
### TaskOnce
Singleton task execution - ensures a task runs exactly once, perfect for initialization routines.
## Quick Start 🏁
### Basic Task Execution
```typescript ```typescript
import { Task } from '@push.rocks/taskbuffer'; import { Task, TaskManager } from '@push.rocks/taskbuffer';
// Create a simple task // Create a simple task
const myTask = new Task({ const dataProcessor = new Task({
name: 'DataProcessor', name: 'ProcessData',
taskFunction: async () => { taskFunction: async (data) => {
const data = await fetchData(); console.log(`Processing: ${data}`);
return processData(data); // Your async logic here
return `Processed: ${data}`;
} }
}); });
// Execute the task // Execute the task
const result = await myTask.trigger(); const result = await dataProcessor.trigger('my-data');
console.log(result); // "Processed: my-data"
``` ```
### Buffered Execution (Rate Limiting) ### Tasks with Progress Tracking 📊
Perfect for API calls or database operations that need throttling: ```typescript
const deploymentTask = new Task({
name: 'DeployApplication',
steps: [
{ name: 'build', description: 'Building application', percentage: 30 },
{ name: 'test', description: 'Running tests', percentage: 20 },
{ name: 'deploy', description: 'Deploying to server', percentage: 40 },
{ name: 'verify', description: 'Verifying deployment', percentage: 10 }
] as const, // Use 'as const' for type inference
taskFunction: async function() {
// TypeScript knows these step names!
this.notifyStep('build');
await buildApplication();
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 ```typescript
const apiTask = new Task({ const apiTask = new Task({
name: 'APICall', name: 'APIRequest',
taskFunction: async (endpoint: string) => { taskFunction: async (endpoint) => {
return await fetch(endpoint); return await fetch(endpoint).then(r => r.json());
}, },
buffered: true, buffered: true,
bufferMax: 3, // Maximum 3 concurrent executions bufferMax: 5, // Maximum 5 concurrent executions
execDelay: 1000 // Wait 1 second between executions execDelay: 100 // Minimum 100ms between executions
}); });
// These will be automatically throttled // Rapid fire 100 calls - only 5 will execute concurrently
for (let i = 0; i < 10; i++) { for (let i = 0; i < 100; i++) {
apiTask.trigger(`/api/data/${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 ### Task Chains - Sequential Workflows
Build complex workflows where each step depends on the previous: Build complex workflows with automatic data flow:

const workflow = new Taskchain({ // Create and execute chain
const dataChain = new Taskchain({
name: 'DataPipeline', name: 'DataPipeline',
taskArray: [fetchTask, transformTask, saveTask] tasks: [fetchTask, transformTask, saveTask]
}); });
// Execute the entire chain const savedCount = await dataChain.trigger();
const result = await workflow.trigger(); console.log(`Saved ${savedCount} items`);
console.log(`Processed ${result.saved} items`);
``` ```
### Parallel Execution - Maximum Performance ### Parallel Execution - Concurrent Processing
Execute multiple independent tasks simultaneously: Execute multiple tasks simultaneously:
```typescript ```typescript
import { Task, Taskparallel } from '@push.rocks/taskbuffer'; import { TaskParallel } from '@push.rocks/taskbuffer';
const tasks = ['user', 'posts', 'comments'].map(resource => const parallel = new TaskParallel({
new Task({ name: 'ParallelProcessor',
name: `Fetch${resource}`, tasks: [
taskFunction: async () => { emailTask,
const data = await fetch(`/api/${resource}`); smsTask,
return data.json(); pushNotificationTask,
webhookTask
]
});
// All tasks execute concurrently
const results = await parallel.trigger(notificationData);
// results = [emailResult, smsResult, pushResult, webhookResult]
```
### TaskManager - Centralized Orchestration
Manage all your tasks from a single point:
```typescript
const taskManager = new TaskManager();
// Add tasks
taskManager.addTask(dataProcessor);
taskManager.addTask(deploymentTask);
// Schedule tasks with cron
taskManager.addAndScheduleTask(backupTask, '0 2 * * *'); // Daily at 2 AM
taskManager.addAndScheduleTask(healthCheck, '*/5 * * * *'); // Every 5 minutes
// Get task metadata
const metadata = taskManager.getTaskMetadata('DeployApplication');
console.log(metadata);
// {
// name: 'DeployApplication',
// status: 'idle' | 'running' | 'completed' | 'failed',
// steps: [...],
// currentProgress: 75,
// runCount: 12,
// lastRun: Date,
// buffered: false,
// bufferMax: undefined,
// version: '1.0.0',
// timeout: 30000
// }
// Get all scheduled tasks
const scheduled = taskManager.getScheduledTasks();
scheduled.forEach(task => {
console.log(`${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);
} }
})
);
const parallelFetch = new Taskparallel({
taskArray: tasks
});
// All tasks execute simultaneously
const [users, posts, comments] = await parallelFetch.trigger();
```
### Scheduled Tasks with TaskManager
Run tasks on a schedule using cron expressions:
```typescript
import { Task, TaskManager } from '@push.rocks/taskbuffer';
const backupTask = new Task({
name: 'DatabaseBackup',
taskFunction: async () => {
await performBackup();
console.log(`Backup completed at ${new Date().toISOString()}`);
} }
}); });
const manager = new TaskManager();
// Add and schedule tasks
manager.addAndScheduleTask(backupTask, '0 0 * * *'); // Daily at midnight
manager.addAndScheduleTask(healthCheck, '*/5 * * * *'); // Every 5 minutes
// Start the scheduler
manager.start();
// Later... stop if needed
manager.stop();
``` ```
### Debounced Tasks - Smart Throttling ### Task Pools
Prevent task spam with intelligent debouncing: Create reusable task pools for load distribution:
```typescript ```typescript
import { TaskDebounced } from '@push.rocks/taskbuffer'; class TaskPool {
private tasks: Task[] = [];
const saveTask = new TaskDebounced({ private currentIndex = 0;
name: 'AutoSave',
taskFunction: async (content: string) => { constructor(poolSize: number, taskConfig: any) {
await saveToDatabase(content); for (let i = 0; i < poolSize; i++) {
console.log('Content saved'); this.tasks.push(new Task({
}, ...taskConfig,
debounceTimeInMillis: 2000 // Wait 2 seconds of inactivity name: `${taskConfig.name}_${i}`
}); }));
// Rapid calls will be debounced
input.addEventListener('input', (e) => {
saveTask.trigger(e.target.value);
});
```
### One-Time Tasks - Initialize Once
Ensure initialization code runs exactly once:
```typescript
import { TaskOnce } from '@push.rocks/taskbuffer';
const initTask = new TaskOnce({
name: 'SystemInitialization',
taskFunction: async () => {
await database.connect();
await cache.initialize();
await loadConfiguration();
console.log('System initialized');
}
});
// Safe to call multiple times - only runs once
await initTask.trigger();
await initTask.trigger(); // This won't run again
```
## Advanced Features 🔥
### Task Dependencies with Pre/Post Hooks
Create sophisticated task relationships:
```typescript
const validationTask = new Task({
name: 'ValidateInput',
taskFunction: async (data) => {
if (!isValid(data)) {
throw new Error('Validation failed');
} }
return data;
} }
});
async execute(data: any) {
const task = this.tasks[this.currentIndex];
this.currentIndex = (this.currentIndex + 1) % this.tasks.length;
return await task.trigger(data);
}
}
const mainTask = new Task({ const processorPool = new TaskPool(5, {
name: 'ProcessData', name: 'DataProcessor',
taskFunction: async (data) => { taskFunction: async (data) => processData(data)
return await complexProcessing(data);
},
preTask: validationTask, // Runs before main task
afterTask: cleanupTask // Runs after main task
}); });
``` ```
### Task Runners - Distributed Execution ### Error Recovery & Retry
The TaskRunner system enables distributed task execution across multiple workers: Implement robust error handling:
```typescript ```typescript
import { TaskRunner } from '@push.rocks/taskbuffer'; const resilientTask = new Task({
name: 'ResilientTask',
const runner = new TaskRunner({ taskFunction: async (data, retryCount = 0) => {
name: 'WorkerNode1', try {
maxConcurrentTasks: 5 return await riskyOperation(data);
}); } catch (error) {
if (retryCount < 3) {
// Register tasks this runner can handle console.log(`Retry ${retryCount + 1}/3`);
runner.registerTask(dataProcessingTask); await new Promise(r => setTimeout(r, 1000 * Math.pow(2, retryCount)));
runner.registerTask(imageResizeTask); return await resilientTask.trigger(data, retryCount + 1);
// Start processing
runner.start();
```
### Buffer Management Strategies
Fine-tune concurrent execution behavior:
```typescript
const task = new Task({
name: 'ResourceIntensive',
taskFunction: async () => { /* ... */ },
buffered: true,
bufferMax: 5, // Max 5 concurrent
execDelay: 100, // 100ms between starts
timeout: 30000 // 30 second timeout
});
```
### Cycle Detection and Prevention
TaskBuffer automatically detects and prevents circular dependencies:
```typescript
const taskA = new Task({
name: 'TaskA',
taskFunction: async () => { /* ... */ },
preTask: taskB // This would create a cycle
});
const taskB = new Task({
name: 'TaskB',
taskFunction: async () => { /* ... */ },
preTask: taskA // Circular dependency detected!
});
```
### Dynamic Task Creation
Create tasks on-the-fly based on runtime conditions:
```typescript
const dynamicWorkflow = async (config: Config) => {
const tasks = config.steps.map(step =>
new Task({
name: step.name,
taskFunction: async (input) => {
return await processStep(step, input);
} }
}) throw error;
); }
}
const chain = new Taskchain({ });
name: 'DynamicWorkflow',
taskArray: tasks
});
return await chain.trigger();
};
``` ```
## API Reference 📚 ### 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;
}
});
```

## Performance Tips 🏎️
1. **Use buffering for I/O operations**: Prevents overwhelming external services
2. **Leverage parallel execution**: When tasks are independent, run them simultaneously
3. **Implement proper error handling**: Use try-catch in task functions
4. **Monitor task execution**: Use the built-in stats and logging
5. **Set appropriate timeouts**: Prevent hanging tasks from blocking your system
## Error Handling 🛡️
```typescript ```typescript
const robustTask = new Task({ const taskManager = new TaskManager({
name: 'RobustOperation', maxConcurrentTasks: 10, // Global concurrency limit
taskFunction: async (input) => { defaultTimeout: 30000, // Default task timeout
try { logLevel: 'info' // Logging verbosity
return await riskyOperation(input);
} catch (error) {
// Log error
console.error(`Task failed: ${error.message}`);
// Optionally retry
if (error.retryable) {
return await riskyOperation(input);
}
// Or return default value
return defaultValue;
}
},
timeout: 5000 // Fail if takes longer than 5 seconds
}); });
``` ```

## Testing 🧪 ## 🚀 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 ```typescript
import { expect, tap } from '@git.zone/tstest'; import { logger } from '@push.rocks/smartlog';
import { Task } from '@push.rocks/taskbuffer';
tap.test('should execute task successfully', async () => { logger.enableConsole();
const result = await myTask.trigger(); logger.level = 'debug';
expect(result).toEqual(expectedValue);
});
tap.start(); // Tasks will now output detailed execution logs
``` ```
