|
|
||||||
|
|
||||||
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.' |
