| REMIX DEFAULT WORKSPACE | |
| Remix default workspace is present when: | |
| i. Remix loads for the very first time | |
| ii. A new workspace is created with 'Default' template | |
| iii. There are no files existing in the File Explorer | |
| This workspace contains 3 directories: | |
| 1. 'contracts': Holds three contracts with increasing levels of complexity. | |
| 2. 'scripts': Contains four typescript files to deploy a contract. It is explained below. | |
| 3. 'tests': Contains one Solidity test file for 'Ballot' contract & one JS test file for 'Storage' contract. | |
| SCRIPTS | |
| The 'scripts' folder has four typescript files which help to deploy the 'Storage' contract using 'web3.js' and 'ethers.js' libraries. | |
| For the deployment of any other contract, just update the contract's name from 'Storage' to the desired contract and provide constructor arguments accordingly | |
| in the file `deploy_with_ethers.ts` or `deploy_with_web3.ts` | |
| In the 'tests' folder there is a script containing Mocha-Chai unit tests for 'Storage' contract. | |
| 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. | |
| Please note, require/import is supported in a limited manner for Remix supported modules. | |
| For now, modules supported by Remix are ethers, web3, swarmgw, chai, multihashes, remix and hardhat only for hardhat.ethers object/plugin. | |
| For unsupported modules, an error like this will be thrown: '<module_name> module require is not supported by Remix IDE' will be shown. |
