OpenZeppelin can be installed directly into your existing node.js project with `npm install --save-exact openzeppelin-solidity`, but OpenZeppelin also integrates directly with [Truffle](https://github.com/ConsenSys/truffle), an Ethereum development environment, which we'll use to get started.
|
||
|
|
|
||
|
|
Please install Truffle and initialize your project:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install -g truffle
|
||
|
|
$ mkdir myproject && cd myproject
|
||
|
|
$ truffle init
|
||
|
|
```
|
||
|
|
|
||
|
|
To install the OpenZeppelin library, run the following in your Solidity project root directory:
|
||
|
|
```sh
|
||
|
|
$ npm init -y
|
||
|
|
$ npm install --save-exact openzeppelin-solidity
|
||
|
|
```
|
||
|
|
|
||
|
|
**Note that OpenZeppelin only lightly follows semantic versioning.** You may encounter breaking changes upon a minor version bump. We recommend pinning the version of OpenZeppelin you use by using the `--save-exact` option.
|
||
|
|
|
||
|
|
After that, you'll get all the library's contracts in the `node_modules/openzeppelin-solidity/contracts` folder. Because Truffle and other Ethereum development toolkits understand `node_modules`, you can use the contracts in the library like so:
|
||
|
|
|
||
|
|
```js
|
||
|
|
import 'openzeppelin-solidity/contracts/ownership/Ownable.sol';
|
||
|
|
|
||
|
|
contract MyContract is Ownable {
|
||
|
|
...
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
