Produce By Path

Description

Produce By Path is a design pattern, which is used to dynamically produce values by using the path to which it is applied. This package helps us easily create and define producer instances.

Installation

npm install produce-by-path

Usage

import ProduceByPath from "produce-by-path"
// CommonJS usage
// const ProduceByPath = require("produce-by-path")


// define producer instance to our liking :)
const instance = new ProduceByPath({
    call: (path, args) => {
        return ({
            path,
            args,
        })
    },
    toPrimitive: (path, hint) => {
        return path.join("--")
    }
})


//      Now we can apply the [[instance]] object with any properties
//      combination and call as a function and receive the desired
//      result as we defined in the [[call]] handler.
console.log( instance.I.love.you("arg1", "arg2") )  
//      {
//          path: ["I", "love", "you"],
//          args: ["arg1", "arg2"]
//      } 


//      We can also apply the [[instance]] object with any properties
//      combination and convert as a primitive value and receive
//      the desired result as we defined in [[toPrimitive]] handler.
console.log( String(instance.I.love.you) )
//      I--love--you

console.log( instance.I.love.you + '')
//      I--love--you

API

new ProduceByPath(handlers)

• handlers \ defines which operations will be intercepted and how to redefine intercepted operations. It can have the following fields:
  • call \ defines call handler, takes the following arguments:
    • path \<String > Array of string, which contains a sequence of those properties on which the call operation was applied.
    • args \ Array of arguments which was passed with the call operation.
  • toPrimitive \ defines toPrimitive handler, takes the following arguments:
    • path \<String > Array of string, which contains a sequence of those properties on which the toPrimitive operation was applied.
    • hint \ can have the following values: "number", "string", "default" see details: toPrimitive
