Do you know what many dApp developers struggle with?

Which data to put on-chain. More data on the chain can drive the cost up. Too much data might render your app unusable. Storing fewer data might not be an option.

Here are some ideas for you to fix this.

A thread. ↓
1. Use A Dedicated Database

This approach will make your dApp into an app.

If you bring in central data storage, you can circumvent the limits of some blockchains, but it doesn't keep the promise of being decentralized.
You can store anything that you can't store on-chain in your database and associate it with a user.

Whenever you need that type of data, you fetch it from your database.

Do you want to get into Web 3.0 as a web developer and take the next step on your awesome journey?

Perfect! 🔥

Time for a small introduction to Web 3.0 development with JavaScript and ethers.js!

A thread. ↓
0. What Is ethers.js?

ethers.js is a JavaScript library that allows you to interact with the Ethereum blockchain, as well as its ecosystem.

Simply stated: You can access your wallet, send transactions, and interact with smart contracts through it.
1. Installation

Let's assume that you already have a JavaScript (frontend) project of any kind set up. If not, do that first.

Before you now install ethers, you should get one last prerequisite: MetaMask.

Do you know what an NFT is?

Some are currently sold for millions, and unknown artists suddenly make a name for themselves and earn hundreds of thousands of dollars.

Let's take a closer look.

A thread. ↓
1. What An NFT Is

Non-fungible tokens (NFTs) are digital assets.

Just imagine a trading card where each card has unique information engraved into it.

No two NFTs are the same and they are thus not interchangeable.
Other than crypto, where one BTC is one, and two BTC are two BTC, two NFTs are one NFT and one NFT.

Just because you have two NFTs of the same type, you cannot sum them up together.

From time to time you read the term Web 3.0. For many of us, however, this term is still mysterious.

Time to shed some light on it and explain what it actually is all about!

A thread. ↓
1. The Web Today

The web as we know it today is actually already Web 2.0.

It is an extension of the original Web (1.0).

In the beginning, the web was meant for websites to provide information and users to consume it.
Web 2.0 changed this and brought the user into the game.

Users started to create the content themselves, while websites became the platform to distribute this new content instead of only consuming information.

Git is by far the most used source control management tool out there.

It is basially an essential to know. And this justifies knowing a few of the most important git commands you need in your daily work.

Here are 19 that any developer should know.

A thread. ↓ 19 essential git commands for every developer.

It initializes a new repository in your current folder and starts the version control flow for your repository. git init
2. Clone a remote repository

You don't necessarily need to create a new repository.

Sometimes you just want to download an existing repository and contribute to it.

This is where git clone comes in. git clone <remoteUrl/>
