Bucket Filter

Build StatusDependency StatusdevDependency Status

Array filtering using buckets. Allows infinite buckets, bucket size limit, keeps input order and discards unmatched elements.

Get Started

npm install bucket-filter

API

filter(input, buckets[, this])

Returns new Array containing values filtered by buckets.

  • input: Array input. (Array)
  • buckets: Array of buckets: (Array)
    • condition: Evaluates bucket selection. Return boolean. (Function)
    • limit: Optional. Bucket size limit. (Number)
  • this: Optional. Value of this when executing each bucket condition. (Mixed)

Usage

// Note: This example uses ES6 syntaxvarfilter=require('bucket-filter')vardata=[{type: 1,title: 'foo-1-1'},// ...{type: 2,title: 'foo-2-1'},// ...]varbuckets=[// Include max 2 values where type is 1{condition: (i)=>i.type===1,limit: 2},// Include all values where type is 2{condition: (i)=>i.type===2}// All values not matching any condition will be dismissed]filter(data,buckets)// → []

Benchmark
