Support TypeChain in deployProxy function

Open frimoldi opened this issue 2 years ago • 8 comments

As discussed in https://github.com/OpenZeppelin/openzeppelin-upgrades/pull/325, this change allows deployProxy to returned a typed Contract instance, so the user can use things like Typechain without loosing contract's types definition.

Usage example in a hardhat script 👇🏽

import { ethers, upgrades } from "hardhat";
import { Greeter__factory } from "../typechain";

async function main() {
  const signer = (await ethers.getSigners())[0];
  const factory = new Greeter__factory(signer);
  const greeter = await upgrades.deployProxy<Greeter__factory>(factory, {
    constructorArgs: ["Fran"],
  });

  await greeter.deployed();

  // this is now type safe
  await greeter.greet();
}
