Lesson 9 : Please explain the Dependencies

[tusharr1411]

Can anyone tell which dependency is for what in Lesson 9
@nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers
ethers

why both (above) ..?

@nomiclabs/hardhat-etherscan okay this is for verification on etherscan

@nomiclabs/hardhat-waffle
chai
ethereum-waffle

hardhat
hardhat-contract-sizer
hardhat-deploy this is for deploy
hardhat-gas-reporter I know this
prettier
prettier-plugin-solidity
solhint this is linter
solidity-coverage I know this is for solidity code coverage
dotenv : Okay, this is for .env

Hello @tusharr1411

1. @nomiclabs/hardhat-ethers:

   • This is a plugin for the Hardhat development environment that integrates the Ethers.js library. It allows you to work with Ethereum smart contracts using Ethers.js within your Hardhat projects. Ethers.js is a popular library for interacting with Ethereum smart contracts and the Ethereum blockchain.

2. ethers:

   • This is the Ethers.js library itself. It's a JavaScript library that provides a clean and simple API for interacting with Ethereum. @nomiclabs/hardhat-ethers uses ethers under the hood for Ethereum-related functionality.

3. @nomiclabs/hardhat-etherscan:

   • This is another plugin for Hardhat. It's used for verifying and interacting with contracts on the Ethereum Etherscan platform. Verification is important when you want to make your smart contract code publicly accessible and auditable on Etherscan.

4. @nomiclabs/hardhat-waffle:

   • Hardhat Waffle is a plugin for Hardhat that provides integration with the Waffle testing library. Waffle is used for writing smart contract tests in Ethereum projects.

5. chai:

   • Chai is a popular assertion library for JavaScript. It is often used in combination with testing frameworks like Mocha or Waffle for writing expressive and readable test cases for Ethereum smart contracts.

6. ethereum-waffle:

   • Ethereum Waffle is a testing library specifically designed for Ethereum smart contract development. It provides tools and utilities to simplify the process of writing and running tests for Ethereum contracts.

7. hardhat-contract-sizer:

   • This is a plugin for Hardhat that helps you analyze and optimize the size of your smart contracts. It's useful for keeping your contract deployments efficient and cost-effective.

8. hardhat-deploy:

   • Hardhat Deploy is a plugin for Hardhat that simplifies the deployment and management of smart contracts in Ethereum projects. It provides a structured way to define and manage deployments.

9. hardhat-gas-reporter:

   • This plugin generates gas usage reports for your smart contract deployments and function calls. It's helpful for optimizing your contract's gas consumption.

10. prettier:

    • Prettier is a code formatter that helps maintain consistent code style and formatting in your project. It can be configured to format Solidity code as well.

11. prettier-plugin-solidity:

    • This is a plugin for Prettier specifically designed for formatting Solidity code. It ensures that your Solidity code follows a consistent and readable style.

12. solhint:

    • Solhint is a linter for Solidity smart contract code. It checks your code against a set of predefined rules to catch potential issues and enforce best practices.

13. solidity-coverage:

    • Solidity Coverage is a testing tool that measures code coverage for your Solidity smart contracts. It helps you identify areas of your code that are not adequately tested.

14. dotenv:

    • Dotenv is a utility for loading environment variables from a .env file into your project's environment. It's commonly used to manage sensitive information and configuration settings in a secure way.

Anyway you can easily google those for more info.
