 1 | This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.
 2 | 
 3 | The project comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. It also comes with a variety of other tools, preconfigured to work with the project code.
 4 | 
 5 | Try running some of the following tasks:
 6 | 
 7 | ```shell
 8 | npx hardhat accounts
 9 | npx hardhat compile
10 | npx hardhat clean
11 | npx hardhat test
12 | npx hardhat node
13 | npx hardhat help
14 | REPORT_GAS=true npx hardhat test
15 | npx hardhat coverage
16 | npx hardhat run scripts/deploy.ts
17 | TS_NODE_FILES=true npx ts-node scripts/deploy.ts
18 | npx eslint '**/*.{js,ts}'
19 | npx eslint '**/*.{js,ts}' --fix
20 | npx prettier '**/*.{json,sol,md}' --check
21 | npx prettier '**/*.{json,sol,md}' --write
22 | npx solhint 'contracts/**/*.sol'
23 | npx solhint 'contracts/**/*.sol' --fix
24 | ```
25 | 
26 | # Etherscan verification
27 | 
28 | To try out Etherscan verification, you first need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Ropsten.
29 | 
30 | In this project, copy the .env.example file to a file named .env, and then edit it to fill in the details. Enter your Etherscan API key, your Ropsten node URL (eg from Alchemy), and the private key of the account which will send the deployment transaction. With a valid .env file in place, first deploy your contract:
31 | 
32 | ```shell
33 | hardhat run --network ropsten scripts/sample-script.ts
34 | ```
35 | 
36 | Then, copy the deployment address and paste it in to replace `DEPLOYED_CONTRACT_ADDRESS` in this command:
37 | 
38 | ```shell
39 | npx hardhat verify --network ropsten DEPLOYED_CONTRACT_ADDRESS "Hello, Hardhat!"
40 | ```
41 | 
42 | # Performance optimizations
43 | 
44 | For faster runs of your tests and scripts, consider skipping ts-node's type checking by setting the environment variable `TS_NODE_TRANSPILE_ONLY` to `1` in hardhat's environment. For more details see [the documentation](https://hardhat.org/guides/typescript.html#performance-optimizations).

 1 | # Getting Started with Create React App
 2 | 
 3 | This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
 4 | 
 5 | ## Available Scripts
 6 | 
 7 | In the project directory, you can run:
 8 | 
 9 | ### `yarn start`
10 | 
11 | Runs the app in the development mode.\
12 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
13 | 
14 | The page will reload if you make edits.\
15 | You will also see any lint errors in the console.
16 | 
17 | ### `yarn test`
18 | 
19 | Launches the test runner in the interactive watch mode.\
20 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
21 | 
22 | ### `yarn build`
23 | 
24 | Builds the app for production to the `build` folder.\
25 | It correctly bundles React in production mode and optimizes the build for the best performance.
26 | 
27 | The build is minified and the filenames include the hashes.\
28 | Your app is ready to be deployed!
29 | 
30 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
31 | 
32 | ### `yarn eject`
33 | 
34 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!**
35 | 
36 | If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
37 | 
38 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
39 | 
40 | You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
41 | 
42 | ## Learn More
43 | 
44 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
