Usage Examples

Nucleus is a collection of pure functions covering a variety of common use cases. Below are a few examples of helpful functions. The documentation can be referenced for a full list of available functions, types, and constants.

Strings

// Capitalize
import { capitalize } from "@behaveware/nucleus";

const result = capitalize("word");
console.log(result); // Word

// Filename From
import { filenameFrom } from "@behaveware/nucleus";

const nameFromUrl: string = filenameFrom("https:/www.behaveware.org/nucleus.jpeg");
console.log(nameFromUrl); // nucleus.jpeg

const nameFromFilepath: string = filenameFrom("C:\\behaveware\\nucleus\\nucleus.jpeg");
console.log(nameFromFilepath); // nucleus.jpeg

// Is Email
import { isEmail } from "@behaveware/nucleus";

const trueResult: boolean = isEmail("support@behaveware.org");
console.log(trueResult); // true

const falseResult: boolean = isEmail("behaveware.org");
console.log(falseResult); // false

Arrays

// Batch Array
import { batchArray } from "@behaveware/nucleus";

const array: any[] = [
  1,
  "string",
  12,
  { size: 10 }
];

const batches = batchArray(array, 2);
console.log(batches[0]); // [ 1, 'string']
console.log(batches[1]); // [12, { size: 10 }]

// Arrays are Equal
import { arraysAreEqual } from "@behaveware/nucleus";

const arrayA = [{ id: "1" }, { id: "2" }];
const arrayB = [{ id: "1" }, { id: "2" }];
const compareType = (
  a: { id: string },
  b: { id: string }
) => {
  return a.id === b.id;
}

const resultAB = arraysAreEqual(
  arrayA,
  arrayB,
  compareType
);

console.log(resultAB); // true;

Bytes

// Byte Conversion
import {
  toKilobytes,
  toMegabytes,
  toGigabytes,
  toTerabytes 
} from "@behaveware/nucleus";

const kilobytes = toKilobytes(1024);
console.log(kilobytes); // 1

const megabytes = toMegabytes(1024 * 1024);
console.log(megabytes); // 1

const gigabytes = toGigabytes(1024 * 1024 * 1024);
console.log(gigabytes); // 1

const terabytes = toTerabytes(1024 * 1024 * 1024 * 1024);
console.log(terabytes); // 1

// Trim Buffer
import { trimBuffer } from "@behaveware/nucleus";

const buffer = Buffer.from("nucleus");
console.log(buffer.byteLength); // 7

const trimmedBuffer = trimBuffer(buffer, 4);
console.log(trimmedBuffer.byteLength); // 4
