Loading Data

This feature allows you to load data from various sources using different loaders. In this example, the CSVLoader is used to load a CSV file from a URL.

const { load } = require('@loaders.gl/core');
const { CSVLoader } = require('@loaders.gl/csv');

async function loadData(url) {
  const data = await load(url, CSVLoader);
  console.log(data);
}

loadData('https://example.com/data.csv');

Parsing Data

This feature allows you to parse data from a string or buffer using different parsers. In this example, the JSONLoader is used to parse a JSON string.

const { parse } = require('@loaders.gl/core');
const { JSONLoader } = require('@loaders.gl/json');

async function parseData(jsonString) {
  const data = await parse(jsonString, JSONLoader);
  console.log(data);
}

parseData('{"key": "value"}');

Creating Custom Loaders

This feature allows you to create and register custom loaders for handling specific data formats. In this example, a CustomLoader is created and registered to load data from a custom format.

const { registerLoaders, Loader } = require('@loaders.gl/core');

class CustomLoader extends Loader {
  parse(arrayBuffer) {
    // Custom parsing logic
    return { data: new Uint8Array(arrayBuffer) };
  }
}

registerLoaders([new CustomLoader()]);

async function loadCustomData(url) {
  const data = await load(url, CustomLoader);
  console.log(data);
}

loadCustomData('https://example.com/data.custom');
