hardhat-template VS smart-contract-best-practices

It seems like every single week, I see things about Foundry. As someone that has been using a fairly standard Hardhat template for my projects the past year, I feel like this gets the job done, but I am wondering what I am missing?

To help getting started easier I am looking into some boilerplate starter kits such as https://github.com/paulrberg/solidity-template etc. Basic question, but what is the best practice in terms of organizing your smart contract dev stuff such as .sol files, hardhat, solhint, solcover, etc. with your front-end (website) dApp code? Do you keep everything in one repository? Do you keep them separated? The front-end part (let's say Sveltekit for example) and ethers.js need the ABI json right? When you deploy your front-end website and are keeping everything in one repo, should you exclude your contract files from the build? I suppose the JS framework will already exclude folders like /contracts that are in the root from the build.

I also really like this template for a web3+React website with a simple connect button: https://github.com/PaulRBerg/solidity-template

..and if you are looking for a general toolchain I really love the starter template here: https://github.com/PaulRBerg/solidity-template

Then i delved into best practises (https://consensys.github.io/smart-contract-best-practices/) and patterns (https://fravoll.github.io/solidity-patterns/) to improve.

Search for solidity exploits on Google, useful one: https://consensys.github.io/smart-contract-best-practices/ there are a lot of possible exploits so deploying one by yourself without audits is a no-go imo

Consensys' Smart Contract Best Practices is a good start for security related stuff (super important because you'll be dealing with people's money in smart contracts) https://consensys.github.io/smart-contract-best-practices/

The first question which any auditing interview concerns is mostly regarding what is your preferred audit process? Answers could be subjective, but I like to follow the industry standard as in this ‘Solcurity Standard’ article by Rari-Capital along with the Consensys’ best practices set of guidelines which pave a path for a thorough audit process.

Security should always be a major priority when developing smart contracts. Millions of dollars are lost to hackers on what seems like a regular basis. As a Web3 developer, you need to continuously stay up to date on the latest security best practices.
