Best way to Import Lodash in your JavaScript Projects for Lowest Bundle Size

hey, friends today I will teach you how to Import Lodash in your JavaScript Projects for Lowest Bundle Size in very easy steps. so let get started with today Code Snippets. Getting different problems is altogether gives a very different experience. today the guide I am going to share with you is how to Import Lodash into your JavaScript Projects.

ADVERTISEMENTS

The most effective method to accurately incorporate explicit elements of the well known lodash library in your web JavaScript project without bringing in the whole library.

Lodash is a very famous JavaScript library that gives a lot of helpful capacities for working with strings, clusters and items in your web projects.

ADVERTISEMENTS

A portion of the Lodash capacities are currently upheld locally in present-day JavaScript, however, the library actually adds worth and saves you time.

For instance, if you want to generate a random number between 1 and 10, the _.random(1, 10) function is a great way to do it, similar to the RANDBETWEEN function of Google Sheets. The _.shuffle() function can help you quickly shuffle an array of values.

The Correct Way to Include Lodash

In the event that your JavaScript project requires Lodash, you can remember the library for your code in 4 distinct ways.

1. Import the entire lodash library

import _ from "lodash";

const capitalizeFirstName = (name) => {
  const result = _.capitalize(name);
  console.log(response);
};

2. Import using named aliases

import { capitalize } from "lodash";

const capitalizeFirstName = (name) => {
  const result = capitalize(name);
  console.log(response);
};

3. Import specific methods by path

import capitalize from "lodash/capitalize";

const capitalizeFirstName = (name) => {
  const result = capitalize(name);
  console.log(response);
};

4. Use per-method lodash packages

import capitalize from "lodash.capitalize";

const capitalizeFirstName = (name) => {
  const result = capitalize(name);
  console.log(response);
};

Which bringing in technique could bring about the most minimal group size?

Choice #1 will incorporate the whole lodash library in your result group and isn’t suggested. The subsequent choice will likewise import the full library and ought to be kept away from.

ADVERTISEMENTS

The #4 technique for bringing in per-strategy lodash bundles will bring about the most minimal group size, yet it isn’t suggested since this methodology will be censured later on variants of lodash.

Methodology #3 is suggested since it will just import the particular Lodash strategies you want and furthermore lessen the group size.

Bonus Tip: Memoization with Lodash

The Lodash library incorporates a memoization method called _.memoize() which is valuable for reserving costly capacities.

ADVERTISEMENTS
import memoize from "lodoash/memoize";

const expensiveFunction = (input) => {
  return input * input;
};

const memoizedFunction = memoize(expensiveFunction);

console.log(memoizedFunction(5)); // Calculates the square of 5
console.log(memoizedFunction(5)); // Returns the cached value

There’s however a big limitation of memoization with Lodash – it will only use the first parameter of the function as the cache key and ignore the rest. Let me explain.

const add = (a, b) => {
  return a + b;
};

const memoizedAdd = _.memoize(add);
console.log(memoizedAdd(1, 2)); // Calculates the sum of 1 and 2 and caches the result
console.log(memoizedAdd(1, 3)); // Returns the cached value which is 3 (incorrect)

As you may have noticed, the second parameter of the function is ignored and thus the result is incorrect since it returned the cached value based on the first parameter itself.

Memoization with Multiple Parameters

To fix this issue, you can utilize an elective memoization library like fast-memoize or you can add a resolver capacity to the memoization technique as displayed beneath.

ADVERTISEMENTS
const multiply = (a, b) => {
  return a * b;
};

const resolver = (...args) => {
  return JSON.stringify(args);
};

const memoizedMultiply = _.memoize(multiply, resolver);

console.log(memoizedMultiply(1, 2)); // Calculates the product of 1 and 2 and caches the result
console.log(memoizedMultiply(1, 3)); // Calculates the product of 1 and 3 and caches the result
console.log(memoizedMultiply(1, 2)); // Returns the cached value

You can draw out the ideas in the comment area. I will most likely think about them. I trust you like them however much we like them offering to you. Have a decent day!
