This is node porting of https://github.com/rinkei/jipcode This library is available in the browser.

I wanted to use the same data for server and client. But I didn't want to use the server's resources. And there was no Japanese address library available in TypeScript, where dependency maintenanced continually.

yarn add jipcode

or

npm install jipcode

Basically, it has same interface with ruby version.

import { locate } from "jipcode";
await locate("1150051")
// returns [{ city: "北区", prefecture: "東京都", town: "浮間", zipcode: "1150051" }]
await locate("1150051", { prefectureCode: true })
// returns [{ city: "北区", prefecture: "東京都", prefectureCode: 13, town: "浮間", zipcode: "1150051" }]

• zipcode: 郵便番号
• prefecture: 都道府県
• city: 市区町村
• town: 町域番地

It will be released after ruby version release.

Feel free to report issues. 😃
