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 🙏

Published

Plugin Vite para consultar CEP e endereco no Web Service ViaCEP via modulo virtual.

Readme

vite-plugin-viacep

Plugin Vite para consulta de CEP e pesquisa de endereco usando o Web Service ViaCEP.

Ele injeta o modulo virtual virtual:viacep, que pode ser usado em qualquer app Vite: Vue, React, Svelte, Vanilla ou outro framework.

Instalar

npm install vite-plugin-viacep

Configurar

import { defineConfig } from 'vite';
import viaCep from 'vite-plugin-viacep';

export default defineConfig({
  plugins: [
    viaCep()
  ]
});

Com proxy no servidor de desenvolvimento:

import { defineConfig } from 'vite';
import viaCep from 'vite-plugin-viacep';

export default defineConfig({
  plugins: [
    viaCep({
      devProxy: true,
      proxyPath: '/__viacep'
    })
  ]
});

Com devProxy: true, o modulo virtual usa /__viacep/... durante o dev server. Em producao, configure um endpoint equivalente no seu backend ou use o modo direto sem proxy.

Tipos do modulo virtual

Adicione em src/vite-env.d.ts:

/// <reference types="vite-plugin-viacep/dist/virtual" />

Uso

import { fetchCep, searchAddress, isValidCep, formatCep } from 'virtual:viacep';

if (isValidCep('01001000')) {
  const address = await fetchCep('01001000');
  console.log(address.logradouro, address.localidade, address.uf);
}

const results = await searchAddress({
  uf: 'RS',
  cidade: 'Porto Alegre',
  logradouro: 'Domingos Jose'
});

console.log(results.map((item) => `${formatCep(item.cep)} ${item.logradouro}`));

API

fetchCep(cep)

Consulta um CEP no formato de 8 digitos. Mascara como 01001-000 tambem funciona porque o plugin remove caracteres nao numericos antes de validar.

searchAddress({ uf, cidade, logradouro })

Pesquisa CEPs por endereco. Regras:

  • uf: 2 letras.
  • cidade: minimo de 3 caracteres.
  • logradouro: minimo de 3 caracteres.
  • O ViaCEP limita o retorno a 50 resultados.

Erros

As funcoes lancam ViaCepError com code:

  • INVALID_CEP
  • INVALID_ADDRESS
  • NOT_FOUND
  • REQUEST_FAILED

Build local

npm install
npm run typecheck
npm run build
npm pack --dry-run
