poe-watch-api

Getting Started

Install with npm:

$ npm install poe-watch-api

Integration:

const PoeWatch = require("poe-watch-api");

Example usage:

Before you can do something with data from the API, categories, leagues and itemdata must be updated. This happens automatically once you create a new PoeWatch object unless you set autoUpdate to false. If you want to start doing things as soon as possible you should consider using the ready event, which is emitted once the above data has been updated.

let poeWatch = new PoeWatch();

poeWatch.on("ready", () => {
  // Request data for a 6-linked relic Shavronne's Wrappings
  poeWatch.requestItem({name: "Shavronne's Wrappings", links: 6, relic: true})
  .then((item) => {
    // Get the sparkline of the median value of the last week in Standard league
    let medianSparkline = item.getPriceDataByLeague("Standard").getHistory().getSparkline("median", 7);
    console.log("Median value history of last week: " + medianSparkline.toString());
  })
  .catch((error) => {
    console.error("An error occurred", error);
  });
});

You can also update the data yourself by setting autoUpdate to false and using the .update() method.

let poeWatch = new PoeWatch({autoUpdate: false});

poeWatch.update()
.then(() => {
  return poeWatch.requestItem({name: "Exalted Orb"});
})
.then((item) => {
  let meanValue = item.getPriceDataByLeague("Standard").getMean();
  console.log("Exalted Orbs are currently worth " + meanValue + " Chaos Orbs in Standard league");
})
.catch((error) => {
  console.error("An error occurred", error);
});

Alternatively you can create a PoeWatch object and make sure it's ready with the .isReady() method if you need the API at a later time.
