Emitting an event

import type { 
const root: Root
A gref to the root of this program.
root } from "membrane";


export function 
function endpoint(req: any): void
endpoint(
req: any
req) {
  switch (`${
req: any
req.
any
method} ${
req: any
req.
any
path}`) {
    case "POST /gh-webhook-path":
      
const root: Root
A gref to the root of this program.
root.
any
ghWebhookReceived.
any
$emit();
    /* ... */
  }
};

Subscribing to an event

Programs can subscribe an action to handle an event. When an event is emitted, the action will be invoked with an additional parameter called event.

import type { 
import nodes
nodes } from "membrane";


export async function 
function sendToSlack(_: any, { event }: {
    event: any;
}): Promise<void>
sendToSlack(
_: any
_, { 
event: any
event }) {
  await 
import nodes
nodes.
any
slack.
any
channel(/* ... */).
any
sendMessage(/* ... */);
}


export async function 
function configure(): Promise<void>
configure() {
  
import nodes
nodes.
any
ghWebhookReceived.
any
$subscribe(
function sendToSlack(_: any, { event }: {
    event: any;
}): Promise<void>
sendToSlack);
}
