recollect-array-js v1.0.3

Motivation

Because in sometimes, we need filter array passing conditions. This library simplify this work.

Installation

Use Yarn

yarn add recollect-array-js

or use NPM

npm i --save recollect-array-js

and then, enjoy!

import RecollectArray from 'recollect-array-js'

Configuration

Without configuration, because we use only JavaScript. ❤️

Availables Predicates for all values

Availables Predicates only when value is Object

💡 Below predicates works only when value is Object

Usage

You can use one or multiples predicates in your filter. We see some use cases.

Flexible Use Case (Hash)

Equal

filters = {
  active: { eq: true }
}

collection = RecollectArray.filter(data, filters)

NotEqual

filters = {
  active: {
    not_eq: true
  }
}

collection = RecollectArray.filter(data, filters)

Exists

Filter only if value be different of null or undefined

filters = {
  members: {
    exists: true
  }
}

collection = RecollectArray.filter(data, filters)

NotExists

filters = {
  members: {
    exists: false
  }
}

collection = RecollectArray.filter(data, filters)

Nested Hash Paths

filters = {
  'schedule.all_day': {
    eq: true
  }
}

collection = RecollectArray.filter(data, filters)

Nested Array Paths

Note the .0 🎉

filters = {
  'numbers.0': {
    eq: '3'
  }
}

collection = RecollectArray.filter(data, filters)

filters = {
  numbers: {
    in: '3' // or in: ['3']
  }
}

collection = RecollectArray.filter(data, filters)

Using default Equal predicate.

RecollectArray.filter(data, { numbers: 3 })

RecollectArray.filter(data, { active: true })

RecollectArray.filter(data, { id: 3 })

If array, you can navigate into self, using property.NUMBER.property

data = [
  {
    schedules: [
      {
        opened: true,
        all_day: true
      },
      {
        opened: false,
        all_day: true
      }
    ]
  },
  {
    schedules: [
      {
        opened: false,
        all_day: true
      },
      {
        opened: false,
        all_day: true
      }
    ]
  }
]

filters = {
  'schedules.0.opened': {
    eq: true
  }
}

collection = RecollectArray.filter(data, filters)

# [{ schedules: [{ opened: true, all_day: true }, { opened: false, all_day: true }] }]

Amazing, you can pass a Function value as value, like this.

filters = {
  'schedules.0.opened': { eq: () => true }
}

collection = Recollect::Array.filter(data, filters)

Combine conditions

Yes, you can combine one or multiple predicates to filter you array.

filters = {
  active: { eq: true },
  numbers: {
    in: [5],
    not_in: '10'
  },
  email: {
    cont: 'email1',
    not_cont: '@gmail'
  },
  'schedule.all_day': {
    in: [true, false]
  }
}

collection = RecollectArray.filter(data, filters)
