## Usage
`@push.rocks/lik` is a versatile package offering a variety of helper classes designed to simplify common tasks in Node.js development. From managing asynchronous operations to handling collections efficiently, this library provides lightweight solutions to enhance your coding workflow. Below, we explore several key features of `@push.rocks/lik`, presenting TypeScript examples to demonstrate their practical application in real-world scenarios.
Use TypeScript for best in class instellisense.
### AsyncExecutionStack
`AsyncExecutionStack` provides controlled execution of asynchronous tasks in two modes:
- **Exclusive tasks**: run one at a time in insertion order, blocking all other tasks until complete.
- **Non-exclusive tasks**: run in parallel, up to an optional concurrency limit.
Create a stack:
```typescript
import { AsyncExecutionStack } from '@push.rocks/lik';
const stack = new AsyncExecutionStack();
```javascript
// import any tool that you need from lik
import { Stringmap, Objectmap, Observablemap } from 'lik';
```
Exclusive tasks execute sequentially and block subsequent tasks (with an optional timeout):
### class Stringmap
```typescript
await stack.getExclusiveExecutionSlot(
async () => {
// exclusive work
},
5000 // optional timeout in milliseconds
);
```
Stringmap allows you to keep track of strings. It allows you to register triggers for certain events
like when a certain string is removed or added to the map
Non-exclusive tasks run in parallel up to the concurrency limit (default: unlimited). Each call returns a promise you can await:
### class Objectmap
```typescript
const p1 = stack.getNonExclusiveExecutionSlot(async () => {
// work 1
}, 2000);
Sometimes you need to keep track of objects, but implementing logic for removing, finding or updating is tedious.
Objectmap takes care of keeping track of objects for you.
const p2 = stack.getNonExclusiveExecutionSlot(async () => {
// work 2
}, 2000);
## Contribution
await Promise.all([p1, p2]);
```
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). :)
Control concurrency and inspect status:
For further information read the linked docs at the top of this readme.
```typescript
// Set maximum concurrent non-exclusive tasks (minimum 1)
stack.setNonExclusiveMaxConcurrency(3);
console.log(stack.getNonExclusiveMaxConcurrency()); // 3
console.log(stack.getActiveNonExclusiveCount()); // currently running tasks
console.log(stack.getPendingNonExclusiveCount()); // tasks waiting for slots
```
### FastMap
`FastMap` offers a high-performance, key-value map optimized for rapid access and modifications, ideal for scenarios requiring frequent read/write operations.
```typescript
import { FastMap } from '@push.rocks/lik';
const myFastMap = new FastMap<string>();
// Add items
myFastMap.addToMap('key1', 'value1');
myFastMap.addToMap('key2', 'value2');
// Retrieve item
const value = myFastMap.getByKey('key1'); // 'value1'
```
### LimitedArray
`LimitedArray` enforces a maximum size on an array, automatically managing its length to prevent it from exceeding a defined limit.
```typescript
import { LimitedArray } from '@push.rocks/lik';
const myLimitedArray = new LimitedArray<number>(5); // limit size to 5
myLimitedArray.addMany([1, 2, 3, 4, 5, 6]);
console.log(myLimitedArray.array); // [2, 3, 4, 5, 6]
```
### LoopTracker
`LoopTracker` helps detect and prevent infinite loops by tracking object references during iterations.
```typescript
import { LoopTracker } from '@push.rocks/lik';
const myLoopTracker = new LoopTracker<object>();
const obj1 = {};
if (myLoopTracker.checkAndTrack(obj1)) {
// proceed with operation
} else {
// potential loop detected
}
```
### ObjectMap
`ObjectMap` facilitates object management, providing functionalities for adding, finding, and removing objects with ease.
```typescript
import { ObjectMap } from '@push.rocks/lik';
interface MyObject {
id: number;
name: string;
}
const myObjectMap = new ObjectMap<MyObject>();
const obj: MyObject = { id: 1, name: 'Test Object' };
// Add object
myObjectMap.add(obj);
// Find object
const found = myObjectMap.findSync(item => item.id === 1);
```
### StringMap
`StringMap` simplifies string collection management, allowing you to add, remove, and query strings effectively.
```typescript
import { Stringmap } from '@push.rocks/lik';
const myStringMap = new Stringmap();
// Add strings
myStringMap.addString('hello');
myStringMap.addStringArray(['world', 'example']);
// Check string presence
const exists = myStringMap.checkString('hello'); // true
```
### TimedAggregator
`TimedAggregator` batches operations over a specified time interval, useful for aggregating logs, metrics, or any data points over time.
```typescript
import { TimedAggregtor } from '@push.rocks/lik';
const myAggregator = new TimedAggregtor<string>({
aggregationIntervalInMillis: 5000, // 5 seconds
functionForAggregation: (items) => {
console.log('Aggregated items:', items);
}
});
// Add items
myAggregator.add('item1');
myAggregator.add('item2');
// After 5 seconds, the functionForAggregation will log the aggregated items
```
### InterestMap and Tree
`InterestMap` provides a structure for managing subscriptions or interests in certain events or entities, optimizing notification mechanisms.
```typescript
import { InterestMap } from '@push.rocks/lik';
const myInterestMap = new InterestMap<string, number>((str) => str);
myInterestMap.addInterest('event1').then((interest) => {
interest.fullfillInterest(42);
});
```
`Tree` offers a way to handle hierarchical data structures, allowing for the composition and traversal of tree-like data sets.
```typescript
import { Tree } from '@push.rocks/lik';
class TreeNode {
constructor(public value: string) {}
}
const myTree = new Tree<TreeNode>();
const rootNode = new TreeNode('root');
myTree.initialize(rootNode);
// Add child nodes
const childNode = new TreeNode('child');
myTree.appendChild(rootNode, childNode);
```
