Commodities

Adapter CommoditiesLoader is a class with a stream method that returns an stream witch emit a commodity in each chunk. The commodity is an object with a shape like the one exposed in EDDB but with camel case attributes and with boolean attributes instead of 0/1 ones.

This is a commodity object example:

{
  "id": 335,
  "name": "Time Capsule",
  "category": {
    "id": 16,
    "name": "Salvage"
  },
  "averagePrice": 4055,
  "isRare": false,
  "maxBuyPrice": null,
  "maxSellPrice": 5223,
  "minBuyPrice": null,
  "minSellPrice": 428,
  "buyPriceLowerAverage": 0,
  "sellPriceUpperAverage": 5038,
  "isNonMarketable": false,
  "edId": 128672163
}

This is an usage example:

const { CommoditiesLoader } = require('eddb-node-adapter');
const commoditiesLoader = new CommoditiesLoader();

const loadStream = commoditiesLoader.stream();

loadStream.on('data', (commodity) => console.dir(commodity, { depth: null, colors: true }));
loadStream.on('error', (err) => console.log('unexpected error', err));
loadStream.on('end', () => console.log('Load finished'));

Populated Systems

Adapter PopulatedSystemsLoader is a class with a stream method that returns an stream witch emit a populated system in each chunk. The system is an object with a shape like the one exposed in EDDB but with camel case attributes.

         pendingStates: [ { id: 67, name: 'Expansion' } ],
         recoveringStates: [] } ] 
}

This is an usage example:

const { PopulatedSystems } = require('eddb-node-adapter');

const populatedSystems = new PopulatedSystems();

const time = process.hrtime();
const loadStream = populatedSystems.stream();

loadStream.on('data', (system) => console.dir(system, { depth: null, colors: true }));
loadStream.on('error', (err) => console.log('unexpected error', err));
loadStream.on('end', () => {
  const [seconds, nanoseconds] = process.hrtime(time);
  console.log('Stream finished in %d seconds and %d nanoseconds', seconds, nanoseconds);
});

loadStream.on('data', (price) => console.dir(price, { depth: null, colors: true }));
loadStream.on('error', (err) => console.log('unexpected error', err));
loadStream.on('end', () => {
  const [seconds, nanoseconds] = process.hrtime(time);
  console.log('Stream finished in %d seconds and %d nanoseconds', seconds, nanoseconds);
});
