data-filler 🍋

make your backend response data shape reliable, with data-filler you can stay away from optional chain.

Quick Start

install

npm i data-filler

• example 1
  missed level 1 key filled by template

import { fillDataByTemplate } from 'data-filler';

const data = { a: 1, b: 2 };
const template = { a: 0, b: 0, c: 0, d: [] };
const filled = fillDataByTemplate(data, template);
// filled is: { a: 1, b: 2, c: 0, d: [] }

• example 2
  fixed incorrect type of key values by template

import { fillDataByTemplate } from 'data-filler';

const data = { a: 1, b: 2, c: { c1: 100 } };
const template = { a: 0, b: 0, c: 0 };
const filled = fillDataByTemplate(data, template);
// filled is: { a: 1, b: 2, c: 0 }

• example 3
  missed child level key filled by template

import { fillDataByTemplate } from 'data-filler';

const data = { a: 1, b: 2, c: { c1: 100 } };
const template = { a: 0, b: 0, c: { c1: 0, c2: 0, c3: 0 } };
const filled = fillDataByTemplate(data, template);
// filled is: { a: 1, b: 2, c: { c1: 100, c2: 0, c3: 0 } }

• example 4
  missed array item key filled by template

import { fillDataByTemplate } from 'data-filler';

const data = { a: 1, b: 2, c: [{ c1: 1, c2: 1 }] };
const template = { a: 0, b: 0, c: [] };
const filled = fillDataByTemplate(data, template, { 'c': { c1: 100, c2: 100, c3: 100 } });
// filled is: { a: 1, b: 2, c: [{ c1: 1, c2: 1, c3: 100 }] }

use 3rd param arrItemTemplates to describe array item data shape

• example 5
  missed child array item key filled by template

import { fillDataByTemplate } from 'data-filler';

const data = { a: 1, b: 2, c: [{ c1: 1, c2: [{ d1: 1 }] }] };
const template = { a: 0, b: 0, c: [] };
const filled = fillDataByTemplate(data, template, {
  'c': { c1: 100, c2: [], c3: 100 },
  'c.c2': { d1: 0, d2: 100 },
});
// filled is: { a: 1, b: 2, c: [{ c1: 1, c2: [{ d1: 1, d2: 100 }], c3: 100 }] }

3rd param arrItemTemplates support key path to describe nested array item data shape
