Installation

NPM

npm install @bsv/simple @bsv/sdk

@bsv/sdk is a peer dependency — it must be installed alongside @bsv/simple.

Entry Points

The library provides three entry points:

Import Path	Environment	Use Case
@bsv/simple/browser	Browser	Connect to user's wallet extension
@bsv/simple/server	Node.js	Server wallet with private key (includes server-only deps)

Browser

import { createWallet, Certifier, DID, Overlay } from '@bsv/simple/browser'
import { CredentialSchema, CredentialIssuer, MemoryRevocationStore } from '@bsv/simple/browser'

Server (Node.js)

import { ServerWallet, FileRevocationStore } from '@bsv/simple/server'

Or with dynamic import (recommended in frameworks like Next.js):

const { ServerWallet } = await import('@bsv/simple/server')

TypeScript

The library ships with full TypeScript declarations. No additional @types/ packages are needed.

import type { BrowserWallet } from '@bsv/simple/browser'
import type { PaymentOptions, TokenOptions, SendOptions } from '@bsv/simple'

Framework-Specific Setup

Next.js

Next.js with Turbopack requires additional configuration to prevent server-only packages from being bundled for the browser. See the Next.js Integration Guide for the required next.config.ts setup.

React / Vite

No special configuration needed. Import from @bsv/simple/browser in your components.

Vanilla TypeScript / Node.js

No special configuration needed. Use @bsv/simple/browser for browser apps or @bsv/simple/server for Node.js scripts.
