blacklight-querystring

Parse/stringify Blacklight query strings to/from normalized search objects. Uses qs under the hood.

npm install blacklight-querystring

usage

var blqs = require('blacklight-querystring')

blqs.parse(queryString)

Parses a query string generated by Blacklight into an object with query, facets, and options keys. Values are uri-decoded and numeric-ish strings are parsed into numbers.

query is the search query used against Blacklight. The value is url-decoded. (default: '')

var parsed = blqs.parse('q=cats+AND+dogs')
console.log(parsed.query)

// {
//   query: 'cats AND dogs',
// }

facets contains facet values found in the query string with the key wrapped in f[ and ][]. (default: {})

var parsed = blqs.parse('f%5Bformat_physical%5D%5B%5D=Videocassette+(VHS)')
console.log(parsed.facets)

// {
//   facets: {
//     format_physical: [
//       'Videocassette (VHS)'
//     ]
//   }
// }

options contains values that are neither the query or facets. Keys/values using object notation are parsed into objects. (default: {})

var parsed = blqs.parse('per_page=25&range%5Bpub_date%5D%5Bstart%5D=1991')
console.log(parsed.options)

// {
//   per_page: 25,
//   range: {
//     pub_date: {
//       begin: 1990
//     }
//   }
// }

blqs.stringify(obj)

Converts an object with keys query, facets, and options into a query string recognized by Blacklight. A query key is converted to the key k in the query string, and facets to f.

var obj = {
  query: 'cats AND dogs',
  facets: {
    format_physical: [
      'Videocassette (VHS)'
    ],
  },
  options: {
    per_page: 25,
    range: {
      pub_date: {
        begin: 1990
      }
    }
  }
}

console.log(blqs.stringify(queryObj))

// 'q=cats+AND+dogs&f%5Bformat_physical%5D%5B%5D=Videocassette+%28VHS%29&per_page=25&range%5Bpub_date%5D%5Bbegin%5D=1990'
