npm buidler

buidler-web3

This plugin integrates Web3.js 1.x into Buidler.

What

This plugin brings to Buidler the Web3 module and an initialized instance of Web3.

Installation

npm install --save-dev @nomiclabs/buidler-web3 web3

And add the following statement to your buidler.config.js:

usePlugin("@nomiclabs/buidler-web3");

Tasks

This plugin creates no additional tasks.

Environment extensions

This plugin adds the following elements to the BuidlerRuntimeEnvironment:

  • Web3: The Web3.js module.
  • web3: An instantiated Web3.js object connected to the selected network.

Usage

Install it and access Web3.js through the Buidler Runtime Environment anywhere you need it (tasks, scripts, tests, etc). For example, in your buidler.config.js:

usePlugin("@nomiclabs/buidler-web3");

// task action function receives the Buidler Runtime Environment as second argument
task("accounts", "Prints accounts", async (_, { web3 }) => {
  
  console.log(await web3.eth.getAccounts());
  
});

module.exports = {};

And then run npx buidler accounts to try it.

Read the documentation on the Buidler Runtime Environment to learn how to access the BRE in different ways to use Web3.js from anywhere the BRE is accessible.

TypeScript support

You need to add this to your tsconfig.json's files array: "node_modules/@nomiclabs/buidler-web3/src/type-extensions.d.ts"
