bodybuilder

All Contributors npm version Build Status

An elasticsearch query body builder. Easily build complex queries for elasticsearch with a simple, predictable api.

bodybuilder

Documentation

Check out the API documentation for details and examples.

Use https://bodybuilder.js.org/ to test your constructions.

Elasticsearch compatibility

Currently aims to support the full elasticsearch query DSL for all versions.

The elasticsearch 1.x query DSL is supported by providing a v1 argument when calling the build function.

Install

npm install bodybuilder --save

Usage

var bodybuilder = require('bodybuilder')
var body = bodybuilder().query('match', 'message', 'this is a test')
body.build() // Build 2.x or greater DSL (default)
body.build('v1') // Build 1.x DSL

For each elasticsearch query body, create an instance of bodybuilder, apply the desired query/filter/aggregation clauses, and call build to retrieve the built query body.

REPL

Try it out on the command line using the node REPL:

# Start the repl
node ./node_modules/bodybuilder/repl.js
# The builder is available in the context variable bodybuilder
bodybuilder > bodybuilder().query('match', 'message', 'this is a test').build()

Queries

bodybuilder().query([arguments])

Creates a query of type queryType.

Arguments

The specific arguments depend on the type of query, but typically follow this pattern:

var body = bodybuilder().query('match', 'message', 'this is a test').build()
// body == {
//   query: {
//     match: {
//       message: 'this is a test'
//     }
//   }
// }

Filters

bodybuilder().filter([arguments])

Creates a filtered query using filter of type filterType.

Arguments

The specific arguments depend on the type of filter, but typically follow this pattern:

bodybuilder().filter('term', 'message', 'test').build()
// body == {
//   query: {
//     bool: {
//       filter: {
//         term: {
//           message: 'test'
//         }
//       }
//     }
//   }
// }

Aggregations

bodybuilder().aggregation([arguments])

Creates an aggregation of type aggregationType.

Arguments

The specific arguments depend on the type of aggregation, but typically follow this pattern:

var body = bodybuilder().aggregation('terms', 'user').build()
// body == {
//   aggregations: {
//     agg_terms_user: {
//       terms: {
//         field: 'user'
//       }
//     }
//   }
// }

Nested aggregations

To nest aggregations, pass a function as the last parameter in [arguments]. The function receives the recently built aggregation instance and is expected to return an Object which will be assigned to .aggs on the current aggregation. Aggregations in this scope behave like builders and you can call the chainable method .aggregation([arguments]) on them just as you would on the main bodybuilder.

var body = bodybuilder().aggregation('terms', 'code', {
      order: { _term: 'desc' },
      size: 1
    }, agg => agg.aggregation('terms', 'name')).build()
// body == {
//   "aggregations": {
//       "agg_terms_code": {
//           "terms": {
//               "field": "code",
//               "order": {
//                   "_term": "desc"
//               },
//               "size": 1
//           },
//           "aggs": {
//               "agg_terms_name": {
//                   "terms": {
//                       "field": "name"
//                   }
//               }
//           }
//       }
//   }
//}

Suggestions

bodybuilder().suggest([arguments])

Creates a phrase or term suggestion.

Arguments

The specific arguments depend on the type of aggregation, but typically follow this pattern:

var body = bodybuilder().suggest('term', 'user', { text: 'kimchy', 'name': 'user_suggest'}).build()
// body == {
//   aggregations: {
//     user_suggest: {
//       text: 'kimchy',
//       term: {
//         field: 'user'
//       }
//     }
//   }
// }

Combining queries, filters, aggregations, and suggestions

Multiple queries and filters are merged using the boolean query or filter (see Combining Filters).

var body = bodybuilder()
  .query('match', 'message', 'this is a test')
  .filter('term', 'user', 'kimchy')
  .filter('term', 'user', 'herald')
  .orFilter('term', 'user', 'johnny')
  .notFilter('term', 'user', 'cassie')
  .aggregation('terms', 'user')
  .suggest('term', 'user', { text: 'kimchy' })
  .build()

// body == {
//   query: {
//     bool: {
//       must: {
//         match: {
//           message: 'this is a test'
//         }
//       },
//       filter: {
//         bool: {
//           must: [
//             {term: {user: 'kimchy'}},
//             {term: {user: 'herald'}}
//           ],
//           should: [
//             {term: {user: 'johnny'}}
//           ],
//           must_not: [
//             {term: {user: 'cassie'}}
//           ]
//         }
//       }
//     },
//   },
//   aggs: {
//     agg_terms_user: {
//       terms: {
//         field: 'user'
//       }
//     }
//   }
//   suggest_term_user: {
//     text: 'kimchy',
//     term: {
//       field: 'user'
//     }
//   }
// }

Nesting Filters and Queries

It is even possible to nest filters, e.g. when some should and must filters have to be combined.

var body = bodybuilder()
    .orFilter('term', 'author', 'kimchy')
    .orFilter('bool', b => b
      .filter('match', 'message', 'this is a test')
      .filter('term', 'type', 'comment')
    )
    .build()

// body == {
//   query: {
//     bool: {
//       filter: {
//         bool: {
//           should: [
//             { term: { author: 'kimchy' } },
//             { bool: { must: [
//               { match: { message: 'this is a test' } },
//               { term: { type: 'comment' } }
//             ] } }
//           ]
//         }
//       }
//     }
//   }
// }

Sort

Set a sort direction using sort(field, direction), where direction defaults to ascending.

var body = bodybuilder()
    .filter('term', 'message', 'test')
    .sort('timestamp', 'desc')
    .sort([{
      "channel": {
        "order": "desc"
      }
    }])
    .sort([
      {"categories": "desc"},
      {"content": "asc"}
    ])
    .build()

// body == {
//   sort: [{
//       "timestamp": {
//         "order": "desc"
//       }
//     },
//     {
//       "channel": {
//         "order": "desc"
//       }
//     },
//     {
//       "categories": {
//         "order": "desc"
//       }
//     },
//     {
//       "content": {
//         "order": "asc"
//       }
//     }
//   ],
//   query: {
//     bool: {
//       filter: {
//         term: {
//           message: 'test'
//         }
//       }
//     }
//   }
// }

Advanced usage: Set a sort configuration object for the given sort field with additional sort properties. sort(field, { sort: 'asc', mode: 'min', ...})

From / Size

Set from and size parameters to configure the offset and maximum hits to be returned.

var body = bodybuilder()
  .filter('term', 'message', 'test')
  .size(5)
  .from(10)
  .build()

// body == {
//   size: 5,
//   from: 10,
//   query: {
//     bool: {
//       filter: {
//         term: {
//           message: 'test'
//         }
//       }
//     }
//   }
// }

Other Options

Set any other search request option using rawOption passing in the key-value pair to include in the body.

var body = bodybuilder()
  .filter('term', 'message', 'test')
  .rawOption('_sourceExclude', 'verybigfield')
  .build()

// body == {
//   _sourceExclude: 'verybigfield',
//   query: {
//     bool: {
//       filter: {
//         term: {
//           message: 'test'
//         }
//       }
//     }
//   }
// }

Test

Run unit tests:

npm test
