BUILDSIDE — TECHNICAL-DEMO BRIEF
https://www.buildside.app/build-in-public/developer-tool-founders

Package a small developer task so someone can reproduce or inspect it.
The EventLens UI on the page is fictional. The local example below is runnable JavaScript, not a hosted webhook service.

Link to your product, documentation or repository:

LOCAL JAVASCRIPT EXAMPLE
Copy the block between BEGIN EXAMPLE and END EXAMPLE into a local .mjs file and run it with Node.js. It uses no packages, credentials, network, or file access. The numeric status values are illustrative return values, not actual HTTP responses.

// BEGIN EXAMPLE
function checkEvent(payload) {
  if (typeof payload?.type !== "string" || payload.type.trim() === "") {
    return { status: 400, message: "Missing field: type" };
  }
  return { status: 202, message: "Accepted by the sample rule" };
}
const original = { id: "evt_demo", event: "build.completed" };
const corrected = { id: "evt_demo", type: "build.completed" };
console.log(JSON.stringify(checkEvent(original)));
console.log(JSON.stringify(checkEvent(corrected)));
// END EXAMPLE

EXPECTED OUTPUT
{"status":400,"message":"Missing field: type"}
{"status":202,"message":"Accepted by the sample rule"}

LIMITS
This checks only whether type is a non-empty string.
It does not check the event ID, allowed event types or the rest of the schema.
It does not implement HTTP handling, authentication, signatures, retries, deduplication, persistence or delivery.
Passing the corrected example does not establish a production-ready integration or any performance claim.

Next useful question:

If using Buildside's GitHub workflow, review eligible newly shipped features, verify the evidence and edit the draft before choosing to publish. Repository activity is not automatically a public announcement. Keep credentials and private payloads out of examples.
