@blazen-dev/wasi

The single-install Blazen package for Cloudflare Workers, Deno, and any other WASI host. Re-exports @blazen-dev/blazen-wasm32-wasi — the napi-rs WASI build of Blazen — and lists the wasm sidecar as a regular dependency so pnpm add @blazen-dev/wasi is all you need.

Install

pnpm add @blazen-dev/wasi
# or
npm install @blazen-dev/wasi

The wasm sidecar (@blazen-dev/blazen-wasm32-wasi) is pulled in automatically as a transitive dependency. No second install, no Vite/Rollup workaround plugins, no ssr.external lists, no manualChunks. Works out of the box with wrangler ≥ 3.15 and @cloudflare/vite-plugin.

Usage

import {
  CompletionModel,
  EmbeddingModel,
  AnthropicProvider,
  Workflow,
} from '@blazen-dev/wasi';

The export surface is identical to the main blazen package; only the binding implementation differs (wasm32-wasi build instead of a per-platform .node binary).

When to use this instead of blazen

The umbrella blazen package targets Node servers and installs a per-platform native .node binary. The wasm sidecar is an optional peer-dependency there, intentionally kept out of Node-only install footprints. Use this package when:

• You're deploying to Cloudflare Workers, Deno Deploy, Fastly Compute, or another WASI host where the native .node binary won't load.
• You want a single pnpm add line that pulls everything needed for the target runtime.
• You want the dependency graph to clearly declare your Workers/edge intent.

Alternative: blazen/workers subpath

If you'd rather list blazen in your dependency tree (mirroring a Node deployment) and explicitly pin the wasm sidecar yourself:

pnpm add blazen @blazen-dev/blazen-wasm32-wasi

import { CompletionModel } from 'blazen/workers';

Both installs are required because the wasm sidecar is an optional peer-dependency on blazen. The blazen/workers subpath uses the same wrangler-static import wasm from '@blazen-dev/blazen-wasm32-wasi/blazen.wasm32-wasi.wasm' loader under the hood as this alias.
