Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

yarn

yarn add validate-chilean-rut

or in a html environment with unpkg

<script crossorigin src="https://unpkg.com/validate-chilean-rut"><script/>

Documentation

validateRut: (rut: number | string) => boolean

Receives either a number or string rut and returns whether it is a valid rut or not

import { validateRut } from "validate-chilean-rut";

console.log(validateRut("96.591.760-8")); // true
console.log(validateRut("96591760-8")); // true
console.log(validateRut("965917608")); // true
console.log(validateRut(965917608)); // true
console.log(validateRut("96.591.760-7")); // false

clearRut: (rut: number | string) => string

Receives either a number or string rut and returns a normalized rut (string)

import { clearRut } from "validate-chilean-rut";

console.log(clearRut("96.591.760-8")); // "965917608"
console.log(clearRut("96591760-8")); // "965917608"
console.log(clearRut(965917608)); // "965917608"

getCheckDigit: (rutWithoutCheckDigit: number | string) => string

Receives rut body (everything but the "- checkDigit") either as a number or string rut and returns the check digit as string

import { getCheckDigit } from "validate-chilean-rut";

console.log(getCheckDigit("96.591.760")); // "8"
console.log(getCheckDigit(96591760)); // "8"

formatRut: (rut: number | string) => string

Receives either a number or string rut and returns a formatted rut (string) with dots and dash.

import { formatRut } from "validate-chilean-rut";

console.log(formatRut("96.591.760-8")); // "96.591.760-8"
console.log(formatRut("96591760-8")); // "96.591.760-8"
console.log(formatRut(965917608)); // "96.591.760-8"

If the rut is not valid, it will format it anyway.

Internal functions (you probably won't use them)

splitRut: (cleanRut: string) => { checkDigit: string; inverseRut: string[];}

Receives a normalized rut and returns the checkDigit and the inverse rut body as an string array

getRutSum: (stringDigitArray: string[]) => number

Receives the inverse rut body (string array) and returns the multiplication sum

getCheckDigitFromSum: (sum: number) => string

Receives the multiplication sum and returns the check digit
