npmスクリプトで、APIからJSONファイルを生成する。

generateJsonFromAPI.js

const fs = require('fs')

const CMS_ROOT_ENDPOINT = `${process.env.CMS_ROOT_ENDPOINT}`

const client = new Client()

const commonOptions = {

    'Content-type': 'application/json',
    'X-API-KEY': CMC_API_KEY,
  },
}

const generateJsonFromAPI = (url, output, options = commonOptions) => {
  console.log(`Starts the generation of '${url}'.`)

  client.get(url, options, (data, response) => {
    const statusCode = response.statusCode

    if (statusCode !== 200) {
      console.log(`statusCode: ${statusCode}`)
      throw new Error('Request failed.')
    }

    const result = JSON.stringify(data)

    // TODO: Does not work if the directory does not exist.
    fs.writeFile(output, result, (error) => {
      if (error) {

      }

      console.log(`✨ '${output}' has been generated.`)
    })
