Creating a project

$ truffle init　　# without default contract

OR

$ truffle unbox <box-name>　　# box-name like MetaCoin

 

Compiling Contracts

 

$ truffle compile　　# all placed in build/contracts/, dot not edit these .json files

 

Running Migrations

 

$ truffle migrate [--reset]　　# run scripts that located in migrations/，Be sure have Ganache installed and running, default choose Ganache network

 

Deployer https://www.trufflesuite.com/docs/truffle/getting-started/running-migrations#deployer

 

Testing Contracts

 

$ truffle test [./tests/hello.js]　　# NOTE:  default network is ‘development‘, so truffle-config.js network configuration need to match the Ganache host and port
