npm install web3

yarn add web3

Use the prebuilt dist/web3.min.js, or build using the [web3.js][repo] repository:

npm run build

Then include dist/web3.min.js in your html file. This will expose Web3 on the window object.

Or via jsDelivr CDN:

<script src="https://cdn.jsdelivr.net/npm/web3@latest/dist/web3.min.js"></script>

UNPKG:

<script src="https://unpkg.com/web3@latest/dist/web3.min.js"></script>

Build the web3.js package:

npm run build

npm test
