| REMIX EXAMPLE PROJECT | |
| Remix example project is present when Remix loads very first time or there are no files existing in the File Explorer. | |
| It contains 3 directories: | |
| 1. 'contracts': Holds three contracts with different complexity level, denoted with number prefix in file name. | |
| 2. 'scripts': Holds two scripts to deploy a contract. It is explained below. | |
| 3. 'tests': Contains one test file for 'Ballot' contract with unit tests in Solidity. | |
| SCRIPTS | |
| The 'scripts' folder contains example async/await scripts for deploying the 'Storage' contract. | |
| For the deployment of any other contract, 'contractName' and 'constructorArgs' should be updated (along with other code if required). | |
| Scripts have full access to the web3.js and ethers.js libraries. | |
| To run a script, right click on file name in the file explorer and click 'Run'. Remember, Solidity file must already be compiled. | |
| Output from script will appear in remix terminal. |
