How to use it?

objectKeysToCamelCaseV2 and objectKeysToSnakeCaseV2

Two available functions

• convert object keys from snake_case to camelCase

import { objectKeysToCamelCaseV2 } from 'keys-converter';

const user = {
    _id: "sf2309sdf0010",
    company_name: "some name",
    user_password: "some@pass123",
    created_at: "2020-01-01",
    updated_at: "2020-01-01"
};

const result = objectKeysToCamelCaseV2(user);

console.log(result);
> `{
    _id: "sf2309sdf0010",
    companyName: "some name",
    userPassword: "some@pass123",
    createdAt: "2020-01-01",
    updatedAt: "2020-01-01"
  }`

• convert object keys from camelCase to snake_case

import { objectKeysToSnakeCaseV2} from 'keys-converter';

const user = {
    _id: "sf2309sdf0010",
    companyName: "some name",
    userPassword: "some@pass123",
    createdAt: "2020-01-01",
    updatedAt: "2020-01-01"
};

const result = objectKeysToSnakeCaseV2(user);

console.log(result);
> `{
    _id: "sf2309sdf0010",
    company_name: "some name",
    user_password: "some@pass123",
    created_at: "2020-01-01",
    updated_at: "2020-01-01"
}`

The function objectKeysToCamelCaseV2 receives an object. You can to infer the return type as argument so the result returned will have types

Inference result and input

const user = {
    _id: "sf2309sdf0010",
    companyName: "some name",
    userPassword: "some@pass123",
    createdAt: "2020-01-01",
    updatedAt: "2020-01-01"
};

/** Dynamic Type */
interface ResultType {
    _id: string;
    company_name: string,
    user_password: string,
    created_at: "2020-01-01",
    updated_at: "2020-01-01"
}

const result = objectKeysToSnakeCaseV2<ResultType>(user);

If you provide the input type the function will validate the arguments, So if you provide the result type the returned value will have "types"

Warning

• Function does not remove the first underscore for security

example If your object has a protected prop like _id It will keep it
