Spawn

Spawn Actor Mesh Runtime for Node/Bun

Installation

Install Spawn CLI

curl -sSL https://github.com/eigr/spawn/releases/download/v1.4.3/install.sh | sh

Getting Started

We recommend you to use Typescript for better usage overall.

This lib supports both Bun and NodeJS runtimes, Bun performs invocations ~2x faster, we recommend using Bun.

Create a new project with

spawn new node hello_world

Run the new project with your preferred package manager

# with yarn
yarn start

# or with pnpm
pnpm start

# or if you want to use bun instead of NodeJS use:
yarn start-bun

Run the Spawn Proxy using the CLI for dev purposes

spawn dev run -p ./protos -s spawn-system -W

Invoking the actor

Thats it! You can test invoking the hello world actor with our pre configured HTTP activator.

curl -vvv -H 'Accept: application/json' http://localhost:9980/v1/hello_world?message=World
