RESAS-API | Cabinet Office,Government Of Japan.

Installation

$ npm install typescript ts-node @types/node axios @aspida/resas

Usage

index.ts

Because there is mock data, this script works without registering API key.

import axios from "axios"
import api, { mock, ApiTypes } from "@aspida/resas"

if (process.env.NODE_ENV === "production") {
  // Get API key here: https://opendata.resas-portal.go.jp/form.html
  axios.defaults.headers.common["X-API-KEY"] = process.env.API_KEY
} else {
  mock()
}

;(async () => {
  const prefCode = ApiTypes.PrefCode.Hokkaido
  const cities = await api().v1.cities.$get({ params: { prefCode } })
  const { cityCode } = cities.result.filter(city => city.cityName === "札幌市")[0]

  const population = await api().v1.population.composition.perYear.$get({
    params: { prefCode, cityCode }
  })

  console.log(population.result)
})()
