KEY-VALIDATOR

Make validation easy and fast.

Installation

  npm i key-validator

Import

  import Validator from "key-validator"

  let V = Validator(...);

Working

Validator function works in 2 steps:-

1. First it digs all sub keys and verifies weather it is null or "".
2. Validating as per user inputs.

Usage

let colors = {
      redish: ["crimson", "orange"],
      greenish: ["yellow", "limegreen", ""],
      blackish: "",
      }

console.log(Validator({
    data: colors
})

OUTPUT Will be:-

{
    stat: false
    errors: [
        0: "greenish['2']"
        1: "blackish"
    ]
    msg: {
    }
}

Explanation:-

1. stat = true | false, Returns validation status.
2. errors = [], Having path of keys that is undefined || null || "" || key.length == 0
3. msg = [], Will show messages defined by user on caught error in particular keys.

Full-Fledged features example:

Here we have a Object Details:-

let Details = {
  name: {
    firstName: "John",
    middleName: "",
    lastName: "Doe",
  },
  age: 22,
  location: {
    country: "India",
    city: "New Delhi",
    streets: "Lorem porem impson",
  },
  sibilings: [],
};

TEST 1

  Validator({
    data: Details,
    ignore: ["name.middleName"],
    rules: {
      age: (value) => {
        return [value > 28, "AGE NOT VALID "];
      },
    },
  });

OUTPUT WILL BE:-

{
    stat: false
    errors: {
        0: age
        1: sibilings
    }
    msg: {
        0: AGE NOT VALID
    }
}

TEST 2

  Validator({
    data: Details,
    ignore: ["name.middleName", "sibilings"],
    rules: {
      age: (value) => {
        return [value > 28, "AGE NOT VALID "];
      },
    },
  });

OUTPUT WILL BE:-

{
    stat: false
    errors: {
        0: age
    }
    msg: {
        0: AGE NOT VALID
    }
}

METHODS :-

1. data => Main object that to be validated.
2. ignore = [...] => Specify key that to be ignored.
3. required = [...] => Only specifed key will be validated and remaining will be ignored.
4. rules = {keyname: (value)=>[STAT, ERROR_MESSAGE]} => Each keys will be validated with function and must return [STAT, ERROR_MESSAGE] to validate.
