# @push.rocks/taskbuffer
flexible task management. TypeScript ready!

## Install
To install `@push.rocks/taskbuffer`, use the following npm command:

```bash
npm install @push.rocks/taskbuffer --save
```

This will add `@push.rocks/taskbuffer` to your project's dependencies, allowing you to use it within your TypeScript project.

## Usage
`@push.rocks/taskbuffer` offers a versatile way to manage tasks in your application. Whether you need simple asynchronous task execution, buffered tasks to limit concurrent executions, or more complex scenarios involving task chaining and parallel execution, `@push.rocks/taskbuffer` has got you covered. Below, you'll find detailed examples showcasing the module's capabilities and how to use them in TypeScript.

### Basic Task Execution
To create and run a simple task:

```typescript
import { Task } from '@push.rocks/taskbuffer';

const simpleTask = new Task({
  name: 'SimpleTask',
  taskFunction: async () => {
    console.log('Executing a simple task');
    // Perform your task here (e.g., fetch data from an API)
  }
});

// Trigger the task
simpleTask.trigger();
```

This basic example creates a task that prints a message to the console when executed.

### Buffered Task Execution
Buffered tasks allow you to throttle task executions, for example, to avoid overwhelming a server with simultaneous requests:

```typescript
import { Task } from '@push.rocks/taskbuffer';

const bufferedTask = new Task({
  name: 'BufferedTask',
  taskFunction: async () => {
    // Task implementation
    console.log('Buffered task execution');
  },
  buffered: true,
  bufferMax: 3 // Maximum number of concurrent executions
});

// Trigger the task multiple times
bufferedTask.trigger();
bufferedTask.trigger();
bufferedTask.trigger();
bufferedTask.trigger();
```

In this scenario, only three instances of `bufferedTask` will run concurrently, thanks to the buffer settings.

### Task Chains
Task chains are a powerful feature that allows you to execute tasks in a specified order:

```typescript
import { Task, Taskchain } from '@push.rocks/taskbuffer';

const firstTask = new Task({
  name: 'FirstTask',
  taskFunction: async () => {
    console.log('First task execution');
    // First task logic
  }
});

const secondTask = new Task({
  name: 'SecondTask',
  taskFunction: async () => {
    console.log('Second task execution');
    // Second task logic
  }
});

const taskChain = new Taskchain({
  name: 'MyTaskChain',
  taskArray: [firstTask, secondTask] // Tasks will be executed in the order they are provided
});

// Trigger the task chain
taskChain.trigger();
```

### Parallel Task Execution
To run tasks in parallel, use `Taskparallel`:

```typescript
import { Task, Taskparallel } from '@push.rocks/taskbuffer';

const taskOne = new Task({
  name: 'TaskOne',
  taskFunction: async () => {
    // Task one logic
    console.log('Task one execution');
  }
});

const taskTwo = new Task({
  name: 'TaskTwo',
  taskFunction: async () => {
    // Task two logic
    console.log('Task two execution');
  }
});

const parallelTask = new Taskparallel({
  taskArray: [taskOne, taskTwo] // These tasks will be executed in parallel
});

// Trigger the parallel tasks
parallelTask.trigger();
```

### Task Scheduling with Task Manager
`@push.rocks/taskbuffer` also provides a `TaskManager` to schedule tasks using cron expressions:

```typescript
import { Task, TaskManager } from '@push.rocks/taskbuffer';

const scheduledTask = new Task({
  name: 'ScheduledTask',
  taskFunction: async () => {
    console.log('Scheduled task execution');
    // Task logic here
  }
});

const taskManager = new TaskManager();
taskManager.addAndScheduleTask(scheduledTask, '0 * * * * *'); // Execute task at the start of every minute

// Start the task manager to enable the scheduled execution
taskManager.start();
```

### Advanced Use Cases
The flexibility of `@push.rocks/taskbuffer` allows for more sophisticated task management scenarios. You can combine the features mentioned above to fit your specific needs, such as chaining parallel tasks, dynamically adding tasks to a manager or chain based on conditions, and much more.

`@push.rocks/taskbuffer` leverages TypeScript's advanced typing features to provide you with clear and predictable APIs, making it easier to build and maintain complex task management logic within your application.
