[fadeev]

A task to check if localnet is still running. Useful for CI for testing example contracts:

#!/bin/bash

set -e

npx hardhat localnet --exit-on-error &

sleep 5

yarn deploy

npx hardhat echo-call \
  --contract 0xc3e53F4d16Ae77Db1c982e75a937B9f60FE63690 \
  --receiver 0xE6E340D132b5f46d1e472DebcD681B2aBc16e57E \
  --network localhost \
  --types '["string"]' alice

npx hardhat localnet-check

npx hardhat echo-call \
  --contract 0xc3e53F4d16Ae77Db1c982e75a937B9f60FE63690 \
  --receiver 0xE6E340D132b5f46d1e472DebcD681B2aBc16e57E \
  --network localhost \
  --types '["uint256"]' 42

npx hardhat localnet-check

By default runs with a delay of 3 seconds to let a call finish.
