confusion about deploy and script folder

[TimeKeyRoll]

Hi! I have almost finished lesson 7 and left with some general doubts about folders.
We have test folder which contains two files named uint for locally test and staging on testnet testing.

Deploy folder has mocks.js for locally and 01 for testnet.

Am i right about the above statments?

Script has two files as well. fund.js and withdarw.js .I understand how the code is written but i don't understand what's the usage of it? And why do we need that? and How scripts are different from tests and deploy.
Could anyone explain in easy terms please?

Hey @MasterofBlockchain from your repo, I can see your directory structure is okay so your statements are right.

Regarding the scripts folder, remember at first we used them to write our scripts to deploy the contracts? We could still use this folder for this purpose however, deploying scripts becomes hard to track if you have a lot of scripts to run or if you want to run multiple scripts at once, so we decided to start using the hardhat-deploy plugin. Using hardhat-deploy makes it easy to keep track of all our deploy scripts and we can easily deploy all of them at once by adding an all tag in module.exports.tags = ["all"] Or if you remember deployments.fixtures(["all"]) also deploys all the scripts at once. This wouldn't have been possible if we were still using the scripts folder.

However, the scripts folder is still usefull for writing standalone scripts that interact with our contracts in specific situations. For example, right now when we want to deploy our contract or mocks we run npx hardhat deploy But what if the only thing we want to do is fund the contract and not all the other complex stuff contained in deploy-mocks.js or deploy-fundme.js files? we don't have an option rather than deploying these two files and specifying the value we want to send in the sendValue variable. But that is a lot of work for just funding or withdrawing from a contract, surely we need an easy way to do so... That's where the scripts folder comes in
The fund.js and withdraw.js files you have in your scripts folder right now, the fund.js is useful if all you want to do is fund the contract, not deploy deploy the contract to a testnet or deploy mocks. The withdraw.js folder is useful if all you want to do is withdraw the funds in your contract. If you look at the code, it is similar to some of the code we have in the other deploy scripts but it is simplified.

The test folder is meant to hold the various tests you have for your smartcontract. Hardhat chai (what you use for testing) is configured to run the scripts in the test folder whenever you run npx hardhat test so it is advisable to keep your tests there.

I hope this explanation helps you.

Hi @othaime-en
I hava a question, In remix if we want to fund, we can just click the fund and If i want to withdraw we can click the withdraw, after deploying the contract.
Similar to that
** HOW TO DO THE SAME THING IN HARDHAT**
To do like that do we need to write the front end part??

@Sairam002 If you want that functionality where you just click a button and you fund or withdraw, then you need to write the frontend. But if all you want is just funding and withdrawing, you can just run the fund.js and withdraw.js files

[Sairam002]

WIthout frontend if we want to use, then we have to deploy every time??

I'm afraid so.

Wow! I pretty much got it in one reading. Wonderful explanation.
