Hosting

These examples won't run in the playground.
This is an advanced topic.
You can host a Clio project using clio host command, you'll be able to import the functions you hosted over the network, on server or in the browser. Let's define a function and host it:
src/main.clio
clio.toml
src/main.clio
fn on-ping ch:
  fn on-ping-inner:
    console.log "Ping received"
    ch -> .send "pong"
​
export fn ping-pong:
  channel () => ch
    -> .on "ping" (on-ping ch)
clio.toml
title = "template-node"
description = ""
version = "0.1.0"
license = "MIT"
main = "src/main.clio"
authors = [ "Your Name <you@example.com>" ]
keywords = ""
​
[build]
directory = "build"
target = "node"
​
[target.node]
directory = "src"
target = "node"
​
[scripts]
test = "No tests specified"
​
[dependencies]
stdlib = "latest"
​
[[servers]]
proto = "ws"
port = 1337
host = "0.0.0.0"
name = "default"
​
[[workers]]
proto = "ws"
url = "ws://localhost:1337"
count = "cpu"
server = "default"
​
[executor]
proto = "ws"
url = "ws://localhost:1337"
wait_for = "cpu"
server = "default"
Running clio host in the root directory of the project will host the project. We can import this in another project:
import ping-pong from "ws://localhost:1337/main.clio"
​
fn on-pong:
  console.log "Pong received"
​
export fn main:
  await ping-pong () => ch
    -> .on "pong" on-pong
​
  fn ping:
    ch -> .send "ping"
​
  setInterval ping 1000
