@bosonprotocol/common

JS lib with common types, interfaces and utilities shared by the core components of the Boson Protocol.

Install

npm install @bosonprotocol/common

# OR

yarn add @bosonprotocol/common

Usage

ABIs

Useful ABIs can be imported.

import { abis } from "@bosonprotocol/common";

const { ProtocolDiamondABI } = abis;

Default configs

We provide default configurations for multiple environments that can be used for easier interaction.

import { getDefaultConfig } from "@bosonprotocol/common";

const defaultConfigOnRopsten = getDefaultConfig("staging");
// {
//   ...otherConfigParameters,
//   subgraphUrl: "https://api.thegraph.com/subgraphs/name/bosonprotocol/ccropsten",
//   contracts: {
//     protocolDiamond: "0x5E3f5127e320aD0C38a21970E327eefEf12561E5"
//   }
// }

Interfaces and types

Interfaces and types can also be imported. This might be useful for implementing custom a Web3LibAdapter or MetadataStorage.

import { Web3LibAdapter, MetadataStorage } from "@bosonprotocol/common";

class CustomWeb3LibAdapter implements Web3LibAdapter {
  // implementation
}

class CustomMetadataStorage implements MetadataStorage {
  // implementation
}

Web3LibAdapter

The core-sdk has the following features:

• web3 lib agnostic
• lightweight
• consists of composable building blocks
• leverages existing tools, such as TypeChain

To achieve these, we use an adapter pattern with Web3LibAdapter being the interface.

An example implementation is the EthersAdapter targeting the ethers library.
