This package exports a dictionary where the keys are the three-digit zip code prefixes, and the values are objects containing id (the three-digit zip), city, and state (if available).
For example:
``js`
{
"440": { "id": "440", "city": "Cleveland", "state": "OH" }
}
`js
import { useState } from "react"
import zips from "zip3"
function MetroParser() {
const [zip, setZip] = useState("90210")
const shortenedZip = zip.slice(0, 3)
const metroObject = zips[shortenedZip] || {}
const { city, state } = metroObject
const metroString = city && state ? ${city}, ${state} : ""
return (
Metro: {metroString}
