Sugg

Sugg debounces the input, load and caches the results, and emit result events when there is new results.

Example

var Sugg = require('sugg')

var sugg = new Sugg({ wait: 300, load: load })
function load(query, cb) {
  setTimeout(function () {
    cb(null, 'results for ' + query)
  }, 200)
}

sugg.on('wait', function () {
  console.log('wait')
})

sugg.on('idle', function () {
  console.log('idle')
})

sugg.on('result', function (result) {
  console.log(result) // outputs `results for hello world` after 500ms (300 + 200)
})

sugg.update('hello world')

Usage

var Sugg = require('sugg')

var sugg = new Sugg({ wait: 200, load: load, maxAge: 1000*60*5, max: 100 })
function load(query, cb) {
  $.ajax(
      { url: 'http://localhost:9200/_suggest'
      , data: JSON.stringify(
        { 'suggestion':
          { 'text': query
          , 'completion':
            { 'field': 'suggest'
            }
          }
        })
      , dataType: 'json'
      , error: function (xhr, status, err) {
          cb(err)
        }
      , success: function (data) {
          cb(null, data)
        }
      }
    )
}

sugg.on('wait', function () {
  // show loader
})

sugg.on('idle', function () {
  // hide loader
})

sugg.on('result', function (suggestions) {
  // update suggestions html
})

sugg.on('error', function (err) {
  // handle error
})

Options

• wait Number of milliseconds to wait for following update before executing the load function. Defaults to 300

• load Method to load results if it's not in the cache. Please see async-cache for details.

• max The maximum size of the cache. Defaults to Infinity.

• maxAge Maximum age in ms. Items are not pro-actively pruned out as they age, but if you try to get a result that is too old, it'll drop it and reload it before giving it to you.

The options object is passed directly to the underlying cache object, so all options for async-cache and lru-cache is also available.
