Installation

Install @streamflow/stream using your preferred package manager.

npm install @streamflow/stream

pnpm add @streamflow/stream

yarn add @streamflow/stream

bun add @streamflow/stream

Browser Polyfills

The SDK uses Node.js built-in modules (e.g., node:crypto). For browser runtimes, you may need polyfills:

• Vite - vite-plugin-node-polyfills
• Webpack - node-polyfill-webpack-plugin
• Rsbuild - rsbuild-plugin-node-polyfill

Transitive dependencies may import bare module names (e.g. crypto) or node:-prefixed names (e.g. node:crypto) - ensure the polyfill covers both forms.

TypeScript configuration

The SDK uses NodeNext module resolution internally. If you're using TypeScript, your tsconfig.json must use "moduleResolution": "NodeNext" (or "bundler" for Vite/Webpack projects) - "node" will fail to resolve subpath exports like @streamflow/stream/solana/api.

{
  "compilerOptions": {
    "moduleResolution": "NodeNext",
    "module": "NodeNext"
  }
}

For bundler-based projects (Vite, Webpack, Rsbuild):

{
  "compilerOptions": {
    "module": "ESNext",
    "moduleResolution": "bundler"
  }
}
