Installation

``bash
$ 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.

`javascript
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)
})()
`

package.json

`json
{
"scripts": {

}
}
`

Run
