🧩Compile

You would use the Hardhat as usual. Client classes will be generated for the compiled contracts automatically

npx hardhat compile

Additional CLI parameters

--sources

Override the default sources folder (/contracts)

npx hardhat compile --sources /other/folder/in/projects/root

---

--artifacts

Override the default output folder

npx hardhat compile --artifacts /foo/bar

---

--watch true

Compile the contracts, watch *.sol files for changes and automatically recompile

npx hardhat compile --watch true

---

--package

Enables the mono-repo structure for the project. The contracts can now be organized into separate package folders within the repository

project/
├─ packages/
│  ├─ Foo/
│  │  ├─ contracts/
│  │  │  ├─ Foo.sol
│  ├─ Bar/
│  │  ├─ contracts/
│  │  │  ├─ Bar.sol

Every package can be implemented separately, but still reference the contracts and interfaces of each other. To compile the package:

npx hardhat compile --package packages/Bar
