Basic JavaScript Runner

[metaskills]

Here is a simple handler I cooked up in a node project.

import env from "./env.js";
env.rollbar;
import { execSync } from "child_process";

export const handler = async (event) => {
 const cwd = process.env.LAMBDA_TASK_ROOT || process.cwd();
 const command = event?.X_LAMBDA_CONSOLE?.run;
 if (command) {
 try {
 const options = {
 cwd,
 env: process.env,
 stdio: ["ignore", "pipe", "pipe"], // stdin, stdout, stderr
 encoding: "utf-8",
 };
 const stdout = execSync(command, options);
 return { statusCode: 0, headers: {}, body: stdout };
 } catch (error) {
 const stderr = error.stderr.toString();
 return { statusCode: 1, headers: {}, body: error.stderr.toString() };
 }
 } else {
 return {
 statusCode: 1,
 headers: {},
 body: `Command not found\n`,
 };
 }
};
