Install

npm install github:flinbein/rollup-plugin-varhub-bundle

Description

The plugin is used to compile typescript code for a varhub VM and calculate the integrity.

Configuration

Vite	vite.config.ts import type { UserConfig } from 'vite'; import varhubBundlePlugin from "@flinbein/rollup-plugin-varhub-bundle"; export default { plugins: [varhubBundlePlugin()] } satisfies UserConfig
Rollup	rollup.config.js import varhubBundlePlugin from "@flinbein/rollup-plugin-varhub-bundle"; export default { input: 'main.js', output: [{ file: 'bundle.min.js', format: 'es', plugins: [varhubBundlePlugin()] }] };

You can pass additional options to plugin: varhubBundlePlugin(options). See ESBuild options. These rules will only apply to building code for the varhub VM.

Usage

varhub-bundle

import "${entrypoint}?varhub-bundle"

returns object with props: module, integrity. It can be used to create room.

const {module, integrity} = await import("./someModule.ts?varhub-bundle");

It is strongly recommended to use as dynamic import.

varhub-bundle:integrity

import "${entrypoint}?varhub-bundle:integrity"

returns string

import integrity from "./someModule.ts?varhub-bundle";

varhub-bundle:module

import "${entrypoint}?varhub-bundle:module"

returns module object with props: main, source

import module from "./someModule.ts?varhub-bundle:module";

Project example

index.ts

import { Varhub } from "@flinbein/varhub-web-client";
// DO NOT USE import "./roomLogic.ts" directly!
import integrity from "./roomLogic.ts?varhub-bundle:integrity";
// integrity: string

const hub = new Varhub("https://example.com/varhub/");

async function createRoom(hub: Varhub){
  const roomConfig = await import("./roomLogic.ts?varhub-bundle");
  // roomConfig: {module: object, integrity: string}
  return hub.createRoom("ivm", {...roomConfig});
}

async function start(){
  const room = await createRoom(hub);
  const client = hub.join(room.id, { integrity });
  client.on("message", console.log);
  await client;
  client.send("hello");
}
start();

roomLogic.ts

import room from "varhub:room";

room.on("connectionMessage", (con, ...args) => {
  room.broadcast(...args);
});
