LowDB is a small local JSON database for Node, Electron and the browser powered by Lodash.⚡️

Sample 💎 :

const low = require('lowdb')
const FileSync = require('lowdb/adapters/FileSync')

const adapter = new FileSync('db.json')
const db = low(adapter)

// Set some defaults (required if your JSON file is empty)
db.defaults({ posts: [], user: {}, count: 0 })
.write()

// Add a post
db.get('posts')
.push({ id: 1, title: 'lowdb is awesome'})
.write()

// Set a user using Lodash shorthand syntax
db.set('user.name', 'typicode')
.write()

// Increment count
db.update('count', n => n + 1)
.write()

Result 🔥:

{
"posts": [
{ "id": 1, "title": "lowdb is awesome"}
],
"user": {
"name": "typicode"
},
"count": 1
}

Learn Webpack in 15 Minutes ⚡️

Build tools have become an integral part of web development, mainly due to the ever-increasing complexity of JavaScript apps. 🛠

Bundlers allow us to package, compile, and organize the many assets and libraries needed for a modern web project. 📦

In this tutorial we will take a look at Webpack, a powerful open-source bundler and preprocessor that can handle a huge variety of different tasks.💎

XState ✨

JavaScript and TypeScript finite state machines and statecharts for the modern web.

Statecharts are a formalism for modeling stateful, reactive systems. ⚡️

This is useful for declaratively describing the behavior of your application, from the individual components to the overall application logic. 🗣

Marky ⏱

JavaScript timer based on performance.mark() and performance.measure(), providing high-resolution timings as well as nice Dev Tools visualizations. 🌈

For browsers that don't support performance.mark(), it falls back to performance.now() or Date.now(). In Node, it uses process.hrtime(). ✨

Are Node.js Modules Singletons ? 🤦🏻‍♂️

Node.js modules can behave like Singletons, but they are not guaranteed to be always singleton❗️

There are two reasons for this and both are mentioned in the official Node.js documentation 📑 :

1- Node’s module caching mechanism is case-sensitive. 🤷🏻‍♂️

2- Modules are cached based on their resolved filename. 🗣

Emojis – the fun and weird parts! 😅

Come get a time out from useful learning and get a brief introduction to the surprisingly interesting world of emojis ! ⚡️

Emojis – to most of us they're just a weird distraction from proper language.

They're actually a rather cool piece of technology (❗️) with a meaningful impact on society. I'll teach you 3 things you didn't know about emojis, but you'll be glad you do ! ✨

Superstruct 🔥

A simple and composable way to validate data in Javascript. ✨

Superstruct makes it easy to define interfaces and then validate JavaScript data against them. ⚠️

Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API. 🧠

But Superstruct is designed for validating data at runtime, so it throws (or returns) detailed runtime errors for you or your end users. 👥

This is especially useful in situations like accepting arbitrary input in a REST or GraphQL API, but it can even be used to validate internal data structures at runtime when needed. ✅

Elasticlunr.js ⚡️

Elasticlunr.js is a lightweight full-text search engine developed in JavaScript for browser search and offline search. 🔍

Elasticlunr.js is developed based on Lunr.js, but more flexible than Lunr.js. 🔥

Elasticlunr.js provides Query-Time boosting, field search, more rational scoring/ranking methodology, fast computation speed and so on. 💎

Elasticlunr.js is a bit like Solr, but much smaller and not as bright, but also provide flexible configuration. ✨
