Hardhat is a Solidity development environment. It comes with a task runner, tools that help you compile your Solidity code, and a local Ethereum test environment. You won't need much more when you use Hardhat.
You somehow want to access your smart contract when it's deployed. ethers.js is perfect for this. It enables you to interact with Ethereum (and other blockchains) and your contract. Great for testing and for your dApp overall!
OpenZeppelin Contracts is a library with reusable contract implementations. Instead of implementing base logic yourself, you can use the library and benefit from battle-tested and secure components.
You did some Solidity tutorials, and now you're stuck because you don't know what else to build?
Let me help you out by giving you three simple ideas for dApps, perfect for beginners!

1οΈβ£ A Voting dApp
Build a dApp that lets users create elections. Any user can start an election and choose a registration period, a voting period, and an ending time.
During the registration period, users can sign up as a candidate.
Once the registration period closes, no one should be able to register anymore. Instead, the voting period starts where anyone can vote for their favorite candidate.
Your frontend should show open elections, the current period, the time remaining, and the candidates.
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. π§΅ππ»
1οΈβ£ 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.

1οΈβ£ CryptoZombies
CryptoZombies is an awesome approach to teaching Solidity. You learn Solidity by basically playing a game, and it's free!
Learning through CryptoZombies definitely isn't as dry as the zombies are themselves!
EthereumDev gives you a full free course that covers everything you need to know in the beginning. It also covers interacting with the blockchain through JavaScript, which definitely helps you to build your own dApps!
Code Reviews are an awesome way to use the experience and knowledge of a team to create good software. Not all review processes are enjoyable, though.
Here are 6 tips to make your review process better and more enjoyable for everyone!

1οΈβ£ Make Expectations Clear
A good review process should both be standardized and individual. The terms of the process should be written down and transparent for everyone on the team. Each team member should know what is expected of them and all team members should agree ...
... on the terms. Changing the terms should always be a democratic process within the team. If the team disagrees on changes or terms, it should discuss the issues until there is consent.
On the other hand, the process should be flexible enough to allow for individuality.
I started to take Twitter seriously last year. Within one year I learned a lot about what advantages having an online presence can actually have.
Here are 4 of the more important things that happen when you build your online presence.

1οΈβ£ You Make Friends
When you interact with other people online, you start to slowly build a connection. You get to know each other and at some point, you perhaps even have a call or a video meeting. This is where strangers can become friends.
Those are the people who interact with you frequently and with whom you have the best discussions. They are there to help when you need them, always.
Those internet friends can also be the ones opening up opportunities to you.
