Trade Volume Data (OSRS's grand exchange graphs)

(Not available on the official OSRS API) This will return trade volume data from the official website.

const data = await OSRS.getTradeVolume(4151);
console.log(data);

Output:

  // ...
  {
    tradeVolume: 1616,
    date: 2020-09-19T23:00:00.000Z,
    dateString: '9/20/2020',
    priceAverage: 2670124,
    priceDaily: 2659245
  },
  {

Bare bones OSRS API that is publicly available.

const itemData = await OSRS.getFromOfficialAPI(OSRS.ITEMS_LIST.Abyssal_whip);
console.log(itemData);

const tradeData = await OSRS.getFromWiki(4151);
console.log(tradeData); // tradeVolume undefined as tracking began in 2018
console.log(tradeData[tradeData.length - 10]); // this should have some tradeVolume data

Output:

// ...
  { // Old data
    date: 1430006400000,

    priceDaily: 2488963,

CORS

Some of the endpoints may require a cors proxy, such as cors anywhere. To supply this to, simply pass it in as a parameter.

const tradeData = await API.getTradeVolume(
  4151,
  'https://cors-anywhere.herokuapp.com/',
);

This should now work in the browser.
