[![NPM Version][npm-version-img]][npm-version-url] [![NPM Downloads][npm-downloads-img]][npm-downloads-url] [![TypeScript Typings][ts-img]][ts-url] ## Reference ### "Base64"
base64Decode(base64Text, encoding, start, end) Decodes to a string according to the specified character encoding in encoding. ```javascript import { base64Decode } from "@corefunc/v8/base64/decode"; // "example text" console.log(base64Decode("ZXhhbXBsZSB0ZXh0")); ```
### "CLI"
argvParse() Parses `process.argv` string. ```javascript import { argvParse } from "@corefunc/v8/cli/argv-parse"; console.dir(argvParse()); // "calc-md5=movie.mp4" // { 'calc-md5': 'movie.mp4' } ```
envParse() Parses `process.env` object. ```javascript import { envParse } from "@corefunc/v8/cli/env-parse"; console.dir(envParse()); // { SHELL: "/bin/zsh", SPACESHIP_VERSION: 3.16 } ```
### "Clone"
clone(value, setPrototype) Deep clone object. Note: don't use on objects containing Functions. ```javascript import { clone } from "@corefunc/v8/clone/clone"; const obj = { prop: "original" }; const array = [obj]; const clonedArray = clone(array); array[0].prop = "changed"; // [ { prop: 'changed' } ] console.log(array); // [ { prop: 'original' } ] console.log(clonedArray); ``` ```javascript import { clone } from "@corefunc/v8/clone/clone"; class Omega { x = 1; y = 2; } const omegaOne = new Omega(); const omegaTwo = clone(omegaOne, true); omegaOne.x = -10; // Omega { x: -10, y: 2 } console.log(omegaOne); // Omega { x: 1, y: 2 } console.log(omegaTwo); ``` ```javascript import { clone } from "@corefunc/v8/clone/clone"; const obj = { prop: "original" }; const setOriginal = new Set([obj]); const setCloned = clone(setOriginal); obj.prop = "changed"; // Set(1) { { prop: 'changed' } } console.log(setOriginal); // Set(1) { { prop: 'original' } } console.log(setCloned); ``` ```javascript import { clone } from "@corefunc/v8/clone/clone"; const obj = { prop: "here is my password" }; const mapFirst = new Map([["secret", obj]]); const mapSecond = clone(mapFirst); const secret = mapFirst.get("secret"); secret.prop = "there is no secret anymore"; // Map(1) { 'secret' => { prop: 'there is no secret anymore' } } console.log(mapFirst); // Map(1) { 'secret' => { prop: 'here is my password' } } console.log(mapSecond); ``` ```javascript import { clone } from "@corefunc/v8/clone/clone"; const alpha = new Error(`Just error`); const beta = clone(alpha); alpha.message = `Now it's not`; // `Now it's not` console.log(alpha.message); // `Just error` console.log(beta.message); ```
cloneMarshalling(value) Deep clone object and sets the prototype. Note: don't use on objects containing Functions. ```javascript import { cloneMarshalling, } from "@corefunc/v8/clone/clone-marshalling"; class Omega { x = 1; y = 2; } const omegaOne = new Omega(); const omegaTwo = cloneMarshalling(omegaOne); omegaOne.x = -10; // Omega { x: -10, y: 2 } console.log(omegaOne); // Omega { x: 1, y: 2 } console.log(omegaTwo); ```
cloneShallow(value) Deep clone any object to plain object. ```javascript import { cloneShallow, } from "@corefunc/v8/clone/clone-shallow"; class Omega { x = 1; y = 2; } const omegaOne = new Omega(); const omegaTwo = cloneShallow(omegaOne); omegaOne.x = -10; // Omega { x: -10, y: 2 } console.log(omegaOne); // { x: 1, y: 2 } console.log(omegaTwo); ```
### "Deserialize"
deserializeFromString(binaryString) Deserialize string to object value. ```javascript import { deserializeFromString, } from "@corefunc/v8/deserialize/from-string"; class Omega { x = 1; y = 2; } const binaryString = `ÿ\ro"\x01xI\x02"\x01yI\x04{\x02`; const obj = deserializeFromString(binaryString); const omega = deserializeFromString(binaryString, Omega); // { x: 1, y: 2 } console.log(obj); // Omega { x: 1, y: 2 } console.log(omega); ```
### "Generate"
generateNumber(minimum, maximum) Secure random number generator. Integers only. ```javascript import { generateNumber, } from "@corefunc/v8/generate/number"; const integer = await generateNumber(-100, 100); // 56 console.log(integer); ```
generateTimeStamp(start, end) Generates timestamp. ```javascript import { generateTimeStamp, } from '@corefunc/v8/generate/time-stamp'; const timeStamp = generateTimeStamp(0, 31); // "2000123101020312345678901234567" console.log(timeStamp); ```
generateUuid4() Generates a random RFC 4122 version 4 UUID. ```javascript import { generateUuid4, } from "@corefunc/v8/generate/uuid4"; // "71ce5138-c908-47b0-b599-327bcec8d213" console.log(generateUuid4()); ```
generateUuid5() Generates a RFC 4122 version 5 UUID. ```javascript import { generateUuid5, } from "@corefunc/v8/generate/uuid5"; const name = `{"a":1}`; const nameSpace = "924a63b2-7e67-435e-94b7-57b5f806b105"; // "a923cf68-cd80-577c-981d-c219fbcb3bee" console.log(generateUuid5(name, nameSpace)); ```
### "Serialize"
serializeToString(value) Serialize value to binary string. ```javascript import { serializeToString, } from "@corefunc/v8/serialize/to-string"; class Omega { x = 1; y = 2; } const omega = new Omega(); const binaryString = serializeToString(omega); // `ÿ\ro"\x01xI\x02"\x01yI\x04{\x02` console.log(binaryString); ```
