REMIX DEFAULT WORKSPACE
|
||||
|
||||
Remix default workspace is present when:
|
||||
i. Remix loads for the very first time
|
||||
ii. A new workspace is created
|
||||
iii. There are no files existing in the File Explorer
|
||||
|
||||
This workspace 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 Solidity test file for 'Ballot' contract & one JS test file for 'Storage' contract
|
||||
|
||||
SCRIPTS
|
||||
|
||||
The 'scripts' folder contains two 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).
|
||||
|
||||
Also, there is a script containing some unit tests for Storage contract inside tests directory.
|
||||
|
||||
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' statement is supported in a limited manner for Remix supported modules.
|
||||
For now, modules supported by Remix are ethers, web3, swarmgw, chai, 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.'
