libhxl-js is a pure-JavaScript library for working with data hashtagged following the Humanitarian Exchange Language (HXL) standard. Its functionality is a subset of libhxl-python for use in browser-side implementations. The library supports the following operations:

• read data from a HXL-hashtagged data source
• perform aggregate operations on HXL data
• apply filters to HXL data (similar to SQL database commands)

Example:

hxl.load('http://example.org/dataset/csv', function (dataset) {
    dataset.forEach(function (row, index) {
        console.log("The value of #adm1 in this row is " + row.get('adm1'));
    }
}
