Package Exports

maplib

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (maplib) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

MapLib

Isomorphic transformations. Map, transform, filter, and morph your objects

Getting Started

$ npm i --save maplib

and then

const Mapper = require('maplib')

const mapper = new Mapper(/* [config] */)

const old = {
  here: {
    there: {
      anywhere: 'Earth'
    }
  }
}

const mappings = [ 'here.there.anywhere:location' ]

const transformation = mapper.map(mappings, old)
// -> { location: 'Earth' }

Config

You can pass in a config object to Mapper to create your own mapping system:

Options

Field	Type	Default
`types`	`Object`	`{}`
`objDelimiter`	`String`	`"."`
`mapDelimiter`	`String`	`":"`
`preFilters`	`Array`	`[]`
`postFilters`	`Array`	`[]`

Example

const mapper = new Mapper({
  objDelimiter: '|',
  mapDelimiter: '->',
  types: { bool: Boolean },
  preFilters: [ FILTER_NULL ],
  postFilters: [ REMOVE_PASSWORD ]
  // add other field to your config here
})
