Truffle is a development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier. With Truffle, you get:
| ℹ️ Contributors: Please see the Development section of this README. | | --- |
$ npm install -g truffle
For a default set of contracts and tests, run the following within an empty project directory:
$ truffle init
From there, you can run
to compile your contracts, deploy those contracts to the network, and run their associated unit tests.
Truffle comes bundled with a local development blockchain server that launches automatically when you invoke the commands above. If you'd like to configure a more advanced development environment we recommend you install the blockchain server separately by running
npm install -g ganache-cli
at the command line.
Please see the Official Truffle Documentation for guides, tips, and examples.
