Get Started

For local development of nevermined-contracts you can either use Docker, or setup the development environment on your machine.

Docker

The simplest way to get started with is using the Nevermined Tools, a docker compose application to run all the Nevermined stack.

Local development

As a pre-requisite, you need:

• Node.js
• yarn

Note: For MacOS, make sure to have node@10 installed.

Clone the project and install all dependencies:

git clone [e-mail]:keyko-io/nevermined-contracts.git
cd nevermined-contracts/

Install dependencies:
```bash
yarn

Compile the solidity contracts:

yarn compile

In a new terminal, launch an Ethereum RPC client, e.g. ganache-cli:

npx ganache-cli@~6.9.1 > ganache-cli.log &

Switch back to your other terminal and deploy the contracts:

yarn test:fast

For redeployment run this instead

yarn clean
yarn compile
yarn test:fast

Upgrade contracts [optional]:

yarn upgrade

Testing

Run tests with yarn test, e.g.:

yarn test test/unit/agreements/AgreementStoreManager.Test.js

Code Linting

Linting is setup for JavaScript with ESLint & Solidity with Ethlint.

Code style is enforced through the CI test process, builds will fail if there're any linting errors.

yarn lint

Packages

To facilitate the integration of nevermined-contracts there are Python, JavaScript and Java packages ready to be integrated. Those libraries include the Smart Contract ABI's. Using these packages helps to avoid compiling the Smart Contracts and copying the ABI's manually to your project. In that way the integration is cleaner and easier. The packages provided currently are:

• JavaScript NPM package - As part of the @keyko-io npm organization, the npm nevermined-contracts package provides the ABI's to be imported from your JavaScript code.
• Python Pypi package - The Pypi nevermined-contracts package provides the same ABI's to be used from Python.
• Java Maven package - The Maven nevermined-contracts package provides the same ABI's to be used from Java.

The packages contains all the content from the doc/ and artifacts/ folders.

In JavaScript they can be used like this:

Install the nevermined-contracts npm package.

npm install @keyko-io/nevermined-contracts

Load the ABI of the NeverminedToken contract on the staging network:

const NeverminedToken = require('@keyko-io/nevermined-contracts/artifacts/NeverminedToken.staging.json')

The structure of the artifacts is:

{
  "abi": "...",
  "bytecode": "0x60806040523...",
  "address": "0x45DE141F8Efc355F1451a102FB6225F1EDd2921d",
  "version": "v0.9.1"
}
