@loaders.gl/core

What is @loaders.gl/core?

@loaders.gl/core is a framework-agnostic library for loading and processing data in various formats. It provides a unified API for handling different types of data sources, making it easier to work with complex data pipelines.

What are @loaders.gl/core's main functionalities?

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');

Other packages similar to @loaders.gl/core

papaparse

PapaParse is a powerful CSV parser that can handle large files and various edge cases. It is specifically designed for parsing CSV data, whereas @loaders.gl/core provides a more general framework for loading and parsing multiple data formats.

axios

Axios is a popular HTTP client for making requests to fetch data from URLs. While it focuses on making HTTP requests, @loaders.gl/core provides a higher-level abstraction for loading and parsing data from various sources.

d3-dsv

d3-dsv is a module from the D3.js library that provides functions for parsing and formatting delimiter-separated values (DSV) files. It is specialized for DSV formats, whereas @loaders.gl/core supports a wider range of data formats and provides a unified API.
