Demo 2. Ethereum development tools & services: smart contracts

Here is presented couple of smart contracts and several approaches how to manage their development process, testing, compilation and deployment.

Tools that we see here:

• Remix IDE and remixd
• Truffle + Ganache

Remix IDE

Allows to write, compile and fast prototype smart contracts right into a browser and does not require to install compiler, web3 and other development things. Only thing you need (at least to store your contracts locally and at the same time use Remix to develop them) is remixd package. It provides a connection between Remix IDE and local host to share contracts' folder and make instant changes. Link to Remix IDE you can find here.

To run remixd just execute

npm run remixshare

Truffle + Ganache

The most engineering way to write smart contracts. More info you can get here.

Contracts could be used in any network where they are deployed. Preconfigured set of networks includes:

• private - connects to a running Ethereum client

• test - is used for running tests and intended to execute with Ganache RPC client.

To run test RPC client execute

npm run run:rpc

To build smart contracts on ether private or test network run

npm run build:private

or

npm run build

Support tools

Includes linters and security checkers. The full list of them you can get here.

Some of these tools are presented here such as solium and eslint.

To run solium linter execute

npm run lint:sol

and to run eslint execute

npm run lint:js
