Below are the dependencies in my packages.json
file:
"dependencies": {
"truffle": "^5.1.51",
"truffle-assertions": "^0.9.2",
"truffle-hdwallet-provider": "^1.0.17",
"web3": "^1.3.0"
}
Why I used these libraries:
truffle
: truffle is a development framework for Ethereum that makes it easy to compile, test, and migrate solidity contracts to Ethereum networks. I usedtruffle
to deploy my smart contracts to theRinkeby
test network.truffle-assertions
: the library has convenience functions designed for solidity assertions inside of truffle tests.truffle-hdwallet-provider
: this libarary was used to enable my truffle deployments to spend test coins from my Metamask wallet on the Rinkeby network as part of deploying my contracts toRinkeby
web3
:
I did not use IPFS.
