fetch = fetch || require('node-fetch')

function jsonstoreio(username /* : string */, path /* : string */, method /* : string */, body /* : ?string */) /* : Promise */ {
  const key = username + 'f83c453cec7234be5bb130fcee5b573bc5fa2573dd647ec54b51075d258c3840'.slice(username.length)
  
  const isUPSERT = method.toUpperCase() !== 'GET' && method.toUpperCase() !== 'DELETE'
  
  const params = (!isUPSERT && body) 
  	? Object.keys(body)
      .map(key => `${key}=${encodeURIComponent(body[key])}`)

      headers: { 'Content-type': 'application/json' },
      method,
      body: isUPSERT ? JSON.stringify(body) : undefined,
