# Changelog
|
||||
|
||||
## 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

### Task
|
||||
|
||||
The fundamental unit of work. A task wraps an asynchronous function and provides powerful execution control.

The fundamental unit of work. A task wraps an asynchronous function and provides powerful execution control, now with step-by-step progress tracking.
|
||||
|
||||
### 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.
|
||||
Centralized task scheduling and management using cron expressions, with rich metadata collection.
|
||||
|
||||
### 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.
|
||||
|
||||
### TaskStep 🆕
|
||||
Granular progress tracking - define named steps with percentage weights for real-time progress monitoring.

### Task with Progress Steps 🆕
|
||||
|
||||
Perfect for API calls or database operations that need throttling:
|
||||
Track granular progress for complex operations - perfect for UI progress bars:
|
||||
|
||||
```typescript
|
||||
const apiTask = new Task({
|
||||
name: 'APICall',
|
||||
taskFunction: async (endpoint: string) => {
|

||||
] as const, // Use 'as const' for full type safety
|
||||
taskFunction: async (inputData) => {
|
||||
// TypeScript knows these step names!
|
||||
dataProcessingTask.notifyStep('validate');
|

|
||||
const result = await dataProcessingTask.trigger();
|
||||
console.log(`Final progress: ${dataProcessingTask.getProgress()}%`); // 100%
|
||||
```
|
||||
|
||||
## TypeScript Generics Support 🔬
|
||||
|
||||
TaskBuffer leverages TypeScript's powerful generics system for complete type safety across your task chains and workflows.
|
||||
|
||||
### Generic Task Functions
|
||||
|
||||
Tasks support generic type parameters for both input and output types:
|
||||
|
||||
```typescript
|
||||
import { Task, ITaskFunction } from '@push.rocks/taskbuffer';
|
||||
|
||||
// Define typed interfaces
|
||||
interface UserData {
|
||||
id: string;
|
||||
name: string;
|
||||
email: string;
|
||||
}
|
||||
|
||||
interface ProcessedUser {
|
||||
userId: string;
|
||||
displayName: string;
|
||||
normalized: boolean;
|
||||
}
|
||||
|
||||
// Create strongly typed tasks
|
||||
const processUserTask = new Task<ProcessedUser>({
|
||||
name: 'ProcessUser',
|
||||
taskFunction: async (user: UserData): Promise<ProcessedUser> => {
|
||||
return {
|
||||
userId: user.id,
|
||||
displayName: user.name.toUpperCase(),
|
||||
normalized: true
|
||||
};
|
||||
}
|
||||
});
|
||||
|
||||
// Type safety enforced at compile time
|
||||
const result: ProcessedUser = await processUserTask.trigger({
|
||||
id: '123',
|
||||
name: 'John Doe',
|
||||
email: 'john@example.com'
|
||||
});
|
||||
```
|
||||
|
||||
### Generic Setup Values
|
||||
|
||||
Tasks can accept setup values through generics, perfect for configuration:
|
||||
|
||||
```typescript
|
||||
interface TaskConfig {
|
||||
apiEndpoint: string;
|
||||
retryCount: number;
|
||||
timeout: number;
|
||||
}
|
||||
|
||||
const configuredTask = new Task<TaskConfig>({
|
||||
name: 'ConfiguredTask',
|
||||
taskSetup: async (): Promise<TaskConfig> => ({
|
||||
apiEndpoint: 'https://api.example.com',
|
||||
retryCount: 3,
|
||||
timeout: 5000
|
||||
}),
|
||||
taskFunction: async (data: any, setupValue: TaskConfig) => {
|
||||
// setupValue is fully typed!
|
||||
for (let i = 0; i < setupValue.retryCount; i++) {
|
||||
try {
|
||||
return await fetchWithTimeout(
|
||||
setupValue.apiEndpoint,
|
||||
setupValue.timeout
|
||||
);
|
||||
} catch (error) {
|
||||
if (i === setupValue.retryCount - 1) throw error;
|
||||
}
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Type-Safe Task Chains
|
||||
|
||||
Chain tasks with preserved type flow:
|
||||
|
||||
```typescript
|
||||
// Each task knows its input and output types
|
||||
const fetchTask = new Task<void>({
|
||||
name: 'FetchUsers',
|
||||
taskFunction: async (): Promise<UserData[]> => {
|
||||
return await api.getUsers();
|
||||
}
|
||||
});
|
||||
|
||||
const filterTask = new Task<void>({
|
||||
name: 'FilterActive',
|
||||
taskFunction: async (users: UserData[]): Promise<UserData[]> => {
|
||||
return users.filter(user => user.isActive);
|
||||
}
|
||||
});
|
||||
|
||||
const mapTask = new Task<void>({
|
||||
name: 'MapToProcessed',
|
||||
taskFunction: async (users: UserData[]): Promise<ProcessedUser[]> => {
|
||||
return users.map(transformUser);
|
||||
}
|
||||
});
|
||||
|
||||
// Type safety flows through the chain
|
||||
const chain = new Taskchain({
|
||||
name: 'UserPipeline',
|
||||
taskArray: [fetchTask, filterTask, mapTask]
|
||||
});
|
||||
|
||||
const finalResult: ProcessedUser[] = await chain.trigger();
|
||||
```
|
||||
|
||||
## Progress Tracking & Metadata 📊 🆕
|
||||
|
||||
TaskBuffer now provides comprehensive progress tracking and metadata collection, perfect for building dashboards and monitoring systems.
|
||||
|
||||
### Step-by-Step Progress
|
||||
|
||||
Define weighted steps for accurate progress calculation:
|
||||
|
||||
```typescript
|
||||
const migrationTask = new Task({
|
||||
name: 'DatabaseMigration',
|
||||
steps: [
|
||||
{ name: 'backup', description: 'Backing up database', percentage: 20 },
|
||||
{ name: 'schema', description: 'Updating schema', percentage: 30 },
|
||||
{ name: 'data', description: 'Migrating data', percentage: 40 },
|
||||
{ name: 'validate', description: 'Validating integrity', percentage: 10 }
|
||||
] as const,
|
||||
taskFunction: async () => {
|
||||
migrationTask.notifyStep('backup');
|
||||
await backupDatabase();
|
||||
console.log(`Progress: ${migrationTask.getProgress()}%`); // ~20%
|
||||
|
||||
migrationTask.notifyStep('schema');
|
||||
await updateSchema();
|
||||
console.log(`Progress: ${migrationTask.getProgress()}%`); // ~50%
|
||||
|
||||
migrationTask.notifyStep('data');
|
||||
await migrateData();
|
||||
console.log(`Progress: ${migrationTask.getProgress()}%`); // ~90%
|
||||
|
||||
migrationTask.notifyStep('validate');
|
||||
await validateIntegrity();
|
||||
console.log(`Progress: ${migrationTask.getProgress()}%`); // 100%
|
||||
}
|
||||
});
|
||||
|
||||
// Get detailed step information
|
||||
const steps = migrationTask.getStepsMetadata();
|
||||
steps.forEach(step => {
|
||||
console.log(`${step.name}: ${step.status} (${step.percentage}%)`);
|
||||
if (step.duration) {
|
||||
console.log(` Duration: ${step.duration}ms`);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Task Metadata Collection
|
||||
|
||||
Get comprehensive metadata about task execution:
|
||||
|
||||
```typescript
|
||||
const task = new Task({
|
||||
name: 'DataProcessor',
|
||||
buffered: true,
|
||||
bufferMax: 5,
|
||||
steps: [
|
||||
{ name: 'process', description: 'Processing', percentage: 100 }
|
||||
] as const,
|
||||
taskFunction: async () => {
|
||||
task.notifyStep('process');
|
||||
await processData();
|
||||
}
|
||||
});
|
||||
|
||||
// Get complete task metadata
|
||||
const metadata = task.getMetadata();
|
||||
console.log({
|
||||
name: metadata.name,
|
||||
status: metadata.status, // 'idle' | 'running' | 'completed' | 'failed'
|
||||
progress: metadata.currentProgress, // 0-100
|
||||
currentStep: metadata.currentStep,
|
||||
runCount: metadata.runCount,
|
||||
lastRun: metadata.lastRun,
|
||||
buffered: metadata.buffered,
|
||||
bufferMax: metadata.bufferMax
|
||||
});
|
||||
```
|
||||
|
||||
### TaskManager Enhanced Metadata
|
||||
|
||||
The TaskManager now provides rich metadata for monitoring and dashboards:
|
||||
|
||||
```typescript
|
||||
const manager = new TaskManager();
|
||||
|
||||
// Add tasks with step tracking
|
||||
manager.addAndScheduleTask(backupTask, '0 2 * * *'); // 2 AM daily
|
||||
manager.addAndScheduleTask(cleanupTask, '0 */6 * * *'); // Every 6 hours
|
||||
|
||||
// Get metadata for all tasks
|
||||
const allTasksMetadata = manager.getAllTasksMetadata();
|
||||
allTasksMetadata.forEach(task => {
|
||||
console.log(`Task: ${task.name}`);
|
||||
console.log(` Status: ${task.status}`);
|
||||
console.log(` Progress: ${task.currentProgress}%`);
|
||||
console.log(` Run count: ${task.runCount}`);
|
||||
console.log(` Schedule: ${task.cronSchedule}`);
|
||||
});
|
||||
|
||||
// Get scheduled tasks with next run times
|
||||
const scheduledTasks = manager.getScheduledTasks();
|
||||
scheduledTasks.forEach(task => {
|
||||
console.log(`${task.name}: Next run at ${task.nextRun}`);
|
||||
if (task.steps) {
|
||||
console.log(` Steps: ${task.steps.length}`);
|
||||
}
|
||||
});
|
||||
|
||||
// Get upcoming executions
|
||||
const nextRuns = manager.getNextScheduledRuns(10);
|
||||
console.log('Next 10 scheduled executions:', nextRuns);
|
||||
```
|
||||
|
||||
### Execute and Track Tasks
|
||||
|
||||
Execute tasks with full lifecycle tracking and automatic cleanup:
|
||||
|
||||
```typescript
|
||||
const manager = new TaskManager();
|
||||
|
||||
const analyticsTask = new Task({
|
||||
name: 'Analytics',
|
||||
steps: [
|
||||
{ name: 'collect', description: 'Collecting metrics', percentage: 30 },
|
||||
{ name: 'analyze', description: 'Analyzing data', percentage: 50 },
|
||||
{ name: 'report', description: 'Generating report', percentage: 20 }
|
||||
] as const,
|
||||
taskFunction: async () => {
|
||||
analyticsTask.notifyStep('collect');
|
||||
const metrics = await collectMetrics();
|
||||
|
||||
analyticsTask.notifyStep('analyze');
|
||||
const analysis = await analyzeData(metrics);
|
||||
|
||||
analyticsTask.notifyStep('report');
|
||||
return await generateReport(analysis);
|
||||
}
|
||||
});
|
||||
|
||||
// Execute with automatic cleanup and metadata collection
|
||||
const report = await manager.addExecuteRemoveTask(analyticsTask, {
|
||||
trackProgress: true
|
||||
});
|
||||
|
||||
console.log('Execution Report:', {
|
||||
taskName: report.taskName,
|
||||
duration: report.duration,
|
||||
stepsCompleted: report.stepsCompleted,
|
||||
finalProgress: report.progress,
|
||||
result: report.result
|
||||
});
|
||||
```
|
||||
|
||||
### Frontend Integration Example
|
||||
|
||||
Perfect for building real-time progress UIs:
|
||||
|
||||
```typescript
|
||||
// WebSocket server for real-time updates
|
||||
io.on('connection', (socket) => {
|
||||
socket.on('startTask', async (taskId) => {
|
||||
const task = new Task({
|
||||
name: taskId,
|
||||
steps: [
|
||||
{ name: 'start', description: 'Starting...', percentage: 10 },
|
||||
{ name: 'process', description: 'Processing...', percentage: 70 },
|
||||
{ name: 'finish', description: 'Finishing...', percentage: 20 }
|
||||
] as const,
|
||||
taskFunction: async () => {
|
||||
task.notifyStep('start');
|
||||
socket.emit('progress', {
|
||||
step: 'start',
|
||||
progress: task.getProgress(),
|
||||
metadata: task.getStepsMetadata()
|
||||
});
|
||||
|
||||
task.notifyStep('process');
|
||||
socket.emit('progress', {
|
||||
step: 'process',
|
||||
progress: task.getProgress(),
|
||||
metadata: task.getStepsMetadata()
|
||||
});
|
||||
|
||||
task.notifyStep('finish');
|
||||
socket.emit('progress', {
|
||||
step: 'finish',
|
||||
progress: task.getProgress(),
|
||||
metadata: task.getStepsMetadata()
|
||||
});
|
||||
}
|
||||
});
|
||||
|
||||
await task.trigger();
|
||||
socket.emit('complete', task.getMetadata());
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Buffer Behavior Deep Dive 🌊
|
||||
|
||||
The buffer system in TaskBuffer provides intelligent control over concurrent executions, preventing system overload while maximizing throughput.
|
||||
|
||||
### How Buffering Works
|
||||
|
||||
When a task is buffered, TaskBuffer manages a queue of executions:
|
||||
|
||||
```typescript
|
||||
const bufferedTask = new Task({
|
||||
name: 'BufferedOperation',
|
||||
taskFunction: async (data) => {
|
||||
console.log(`Processing: ${data}`);
|
||||
await simulateWork();
|
||||
return `Processed: ${data}`;
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 3 // Maximum 3 concurrent executions
|
||||
});
|
||||
|
||||
// Trigger 10 executions rapidly
|
||||
for (let i = 0; i < 10; i++) {
|
||||
apiTask.trigger(`/api/data/${i}`);
|
||||
bufferedTask.trigger(`Item ${i}`);
|
||||
}
|
||||
|
||||
// What happens:
|
||||
// 1. First 3 tasks start immediately
|
||||
// 2. Items 4-10 are queued
|
||||
// 3. As each task completes, next queued item starts
|
||||
// 4. Never more than 3 tasks running simultaneously
|
||||
```
|
||||
|
||||
### Buffer Truncation Behavior
|
||||
|
||||
When buffer limit is reached, new calls are intelligently managed:
|
||||
|
||||
```typescript
|
||||
const truncatingTask = new Task({
|
||||
name: 'TruncatingBuffer',
|
||||
taskFunction: async (data) => {
|
||||
await processData(data);
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 5 // Maximum 5 in buffer
|
||||
});
|
||||
|
||||
// Rapid fire 100 calls
|
||||
for (let i = 0; i < 100; i++) {
|
||||
truncatingTask.trigger(`Data ${i}`);
|
||||
}
|
||||
|
||||
// Buffer behavior:
|
||||
// - First 5 calls: Added to buffer and start processing
|
||||
// - Calls 6-100: Each overwrites the 5th buffer slot
|
||||
// - Result: Only processes items 0,1,2,3, and 99 (last one)
|
||||
// - This prevents memory overflow in high-frequency scenarios
|
||||
```
|
||||
|
||||
### Advanced Buffer Strategies
|
||||
|
||||
#### 1. **Sliding Window Buffer**
|
||||
Perfect for real-time data processing where only recent items matter:
|
||||
|
||||
```typescript
|
||||
const slidingWindowTask = new Task({
|
||||
name: 'SlidingWindow',
|
||||
taskFunction: async (data) => {
|
||||
return await analyzeRecentData(data);
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 10, // Keep last 10 items
|
||||
execDelay: 100 // Process every 100ms
|
||||
});
|
||||
|
||||
// In a real-time stream scenario
|
||||
dataStream.on('data', (chunk) => {
|
||||
slidingWindowTask.trigger(chunk);
|
||||
// Older items automatically dropped when buffer full
|
||||
});
|
||||
```
|
||||
|
||||
#### 2. **Throttled Buffer**
|
||||
Combine buffering with execution delays for rate limiting:
|
||||
|
||||
```typescript
|
||||
const apiRateLimiter = new Task({
|
||||
name: 'RateLimitedAPI',
|
||||
taskFunction: async (request) => {
|
||||
return await api.call(request);
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 10, // Max 10 queued requests
|
||||
execDelay: 1000 // 1 second between executions
|
||||
});
|
||||
|
||||
// Requests are queued and executed at 1/second
|
||||
// Prevents API rate limit violations
|
||||
```
|
||||
|
||||
#### 3. **Priority Buffer** (Custom Implementation)
|
||||
Implement priority queuing with buffer management:
|
||||
|
||||
```typescript
|
||||
class PriorityBufferedTask extends Task {
|
||||
private priorityQueue: Array<{data: any, priority: number}> = [];
|
||||
|
||||
constructor(options) {
|
||||
super({
|
||||
...options,
|
||||
taskFunction: async (item) => {
|
||||
// Process based on priority
|
||||
return await this.processByPriority(item);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
triggerWithPriority(data: any, priority: number) {
|
||||
if (this.priorityQueue.length >= this.bufferMax) {
|
||||
// Remove lowest priority item if buffer full
|
||||
this.priorityQueue.sort((a, b) => b.priority - a.priority);
|
||||
this.priorityQueue.pop();
|
||||
}
|
||||
this.priorityQueue.push({data, priority});
|
||||
this.priorityQueue.sort((a, b) => b.priority - a.priority);
|
||||
return this.trigger(this.priorityQueue.shift());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Buffer Monitoring
|
||||
|
||||
Track buffer utilization and performance:
|
||||
|
||||
```typescript
|
||||
const monitoredTask = new Task({
|
||||
name: 'MonitoredBuffer',
|
||||
taskFunction: async (data) => {
|
||||
const startTime = Date.now();
|
||||
const result = await processData(data);
|
||||
console.log(`Processing time: ${Date.now() - startTime}ms`);
|
||||
console.log(`Buffer utilization: ${monitoredTask.bufferRunner.bufferCounter}/${monitoredTask.bufferMax}`);
|
||||
return result;
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 20
|
||||
});
|
||||
|
||||
// Monitor buffer saturation
|
||||
setInterval(() => {
|
||||
const utilization = (monitoredTask.bufferRunner.bufferCounter / monitoredTask.bufferMax) * 100;
|
||||
if (utilization > 80) {
|
||||
console.warn(`Buffer near capacity: ${utilization.toFixed(1)}%`);
|
||||
}
|
||||
}, 1000);
|
||||
```
|
||||
|
||||
### Buffer Best Practices
|
||||
|
||||
1. **Choose appropriate buffer sizes**:
|
||||
- I/O operations: 5-10 concurrent
|
||||
- CPU-intensive: Number of cores
|
||||
- API calls: Based on rate limits
|
||||
|
||||
2. **Handle buffer overflow gracefully**:
|
||||
```typescript
|
||||
const task = new Task({
|
||||
taskFunction: async (data) => {
|
||||
try {
|
||||
return await process(data);
|
||||
} catch (error) {
|
||||
if (error.code === 'BUFFER_OVERFLOW') {
|
||||
// Implement backoff strategy
|
||||
await delay(1000);
|
||||
return task.trigger(data);
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 10
|
||||
});
|
||||
```
|
||||
|
||||
3. **Monitor and adjust dynamically**:
|
||||
```typescript
|
||||
// Adjust buffer size based on system load
|
||||
const adaptiveTask = new Task({
|
||||
name: 'AdaptiveBuffer',
|
||||
taskFunction: async (data) => {
|
||||
const cpuLoad = await getSystemLoad();
|
||||
if (cpuLoad > 0.8) {
|
||||
adaptiveTask.bufferMax = Math.max(2, adaptiveTask.bufferMax - 1);
|
||||
} else if (cpuLoad < 0.5) {
|
||||
adaptiveTask.bufferMax = Math.min(20, adaptiveTask.bufferMax + 1);
|
||||
}
|
||||
return await process(data);
|
||||
},
|
||||
buffered: true,
|
||||
bufferMax: 10
|
||||
});
|
||||
```

### 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
