Step 5 - Configure a Variable
In the last step, we were able to hard-code the channel for the Slack message. But if you want the channel to be configurable outside of the code, you can use a variable.
Add a variable to the helloSlack action
Change the following 3 lines in src/helloSlack.js:
import { defineAction } from "@runlightyear/lightyear";
import { Slack } from "@runlightyear/slack";
defineAction({
name: "helloSlack",
title: "Hello Slack",
description: "Send a message to Slack",
apps: ["slack"],
variables: ["channel"],
run: async ({ auths, variables }) => {
const slack = new Slack({ auth: auths.slack });
await slack.postMessage({
channel: variables.channel,
text: "Hello Slack!",
});
console.info("Posted message to Slack");
},
});Enter a value for the new variable
Go back to the Config tab and enter a value for the new channel variable.
