JavaScript

Goal

Write a JavaScript block as an ES module. Time: 5 minutes. Needs: Node.js.

language: javascript

import { readFileSync } from "node:fs";

const path = process.env.TERMORQ_INPUT;
if (!path) throw new Error("TERMORQ_INPUT is missing");
const data = JSON.parse(readFileSync(path, "utf8"));
const text = data?.trigger?.text;
if (typeof text !== "string") {
  throw new Error("trigger.text must be a string");
}
console.log(JSON.stringify({ message: text }));

Things to know

The runner writes your code to snippet.mjs, so it’s an ES module: use import, not require. Top-level await works.
For Code file, .js and .mjs are inferred as JavaScript.
Node built-ins (node:fs, node:path, and fetch) are available. npm packages aren’t installed for you.
Never use JSON.stringify(obj, null, 2) for the final line, because it prints several lines.

Check your run

Execute step prints {"message":"Hello from curl"}.

Exercise

Publish chars: an array of the unique characters in the text, sorted.

Details

import { readFileSync } from "node:fs";
const { trigger } = JSON.parse(readFileSync(process.env.TERMORQ_INPUT, "utf8"));
console.log(JSON.stringify({ chars: [...new Set(trigger.text)].sort() }));

Declare chars: { type: array, items: { type: string } }.
