ring-buffer-uint8array (RingBufferUint8Array)

https://npmjs.com/package/@telemok/ring-buffer-uint8array is the typescript circular ring buffer uint8array with .push .shift .read .write find operations

Features

• Work in Uint8array - it faster and native.
• UART/USART stream parsing compatible.
• Argument checking and fast functions without checking.
• Fast and easy to learn.
• Ring overwrite on/off.
• Any buffer size, not 2^n.
• NodeJs and browser Javascript support

Installation:

• Create your NodeJs, Browser or Webview app.
• run: npm install @telemok/ring-buffer-uint8array
• import { RingBufferUint8Array } from "@telemok/RingBufferUint8Array.ts"
• Ready.

Examples:

• Parsing students database

import {RingBufferUint8Array} from "@telemok/RingBufferUint8Array"

const textEncoder = new TextEncoder();
const textDecoder = new TextDecoder();

/* Create instance of RingBuffer */
let rb = new RingBufferUint8Array(10);

/* Data to parse, like streaming from UART. */
const inputStream = "Hello\r\nworld! May be.";

/* Separators to split data. */
const binarySeparators = [textEncoder.encode('\r\n'), textEncoder.encode('!')];

/* Iterate stream data.*/
for(let c of inputStream)
{
    /* Push bytes from stream. */
    rb.pushByte(textEncoder.encode(c)[0]);
    
    /* Extract Uint8array from ringbuffer without separator if separator match or return null. */
    let arr = rb.ifEndsWithUint8ArraysThenFlushUint8Array(binarySeparators, false);
    if(arr !== null)
        console.log("Find: ", textDecoder.decode(arr));
}

It will return:
Find: Hello
Find: world
