Platforms

Primate runs on Node, Bun, and Deno via rcompat. It avoids runtime-specific APIs and abstracts differences via rcompat. You build and run with your chosen runtime, and target Web or Native.

Why rcompat

Using rcompat keeps apps portable and future-proof:

• No vendor lock-in to a single runtime
• One codebase, three runtimes
• Unified stable interfaces insulate you from runtime churn
• Matches Primate's stance elsewhere (frontend, backend, database agnostic)

Run

Dev

# Node
npx primate

# Bun
bunx --bun primate

# Deno
deno run -A npm:primate

Build

# Node
npx primate build

# Bun
bunx --bun primate build

# Deno
deno run -A npm:primate build

Serve a Build

# Node
npx primate serve

# Bun
bunx --bun primate serve

# Deno
deno run -A npm:primate serve

Unified APIs with rcompat

Prefer rcompat packages over runtime-specific APIs.

Filesystem

import FileRef from "@rcompat/fs/FileRef";

const base = new FileRef("static");
const file = base.join("logo.svg");

HTTP Status

import Status from "@rcompat/http/Status";

return new Response("ok", { status: Status.OK });

MIME Types

import mime from "@rcompat/mime/text/plain";
import resolve from "@rcompat/mime/resolve";

const known = mime;            // "text/plain"
const byExt = resolve(".svg"); // "image/svg+xml"

Runtime Support

Primate aims for complete interoperability across various runtimes and targets. In the table below, some cells are left blank where a platform has not yet been wired up.
