mgsrBotEndpoint

An interactive, runnable TypeScript val by stevekrouse

verify_discord_signature Verify HTTP signatures coming from Discord. public_key should be the Ed25519 public key from Discord, as a hex string body should be the request body as a string. If you have a JSON object as the request body, use JSON.stringify. signature should be the X-Signature-Ed25519 header timestamp should be the X-Signature-Timestamp header You must return a 401 error and return early if this function returns false, otherwise you will pretty quickly get a big scary warning from Discord that your endpoint has been removed. Note that you'll only be able to add one once you've integrated this correctly. As this function only deals with strings, it doesn't matter whether you use an Express or web endpoint.

Proxied fetch - Docs ↗ The Javascript Fetch API is directly available within a Val. However sometimes fetch calls are blocked by the receiving server for using particular IP addresses. Additionally, network blips or unreliable web services may lead to failures if not handled properly. The Val Town standard library contains an alternative version, std/fetch , that wraps the JavaScript Fetch API to provide additional functionality. The fetch function from std/fetch reroutes requests using a proxy vendor so that requests obtain different IP addresses. It also automatically retries failed requests several times. Note that using std/fetch will be significantly slower than directly calling the Javascript Fetch API due to extra network hops. Usage After importing std/fetch , the fetch method is used with the same signature as the Javascript Fetch API. import { fetch } from "https://esm.town/v/std/fetch"; let result = await fetch("https://api64.ipify.org?format=json"); let json = await result.json(); console.log(json.ip); If you run the above code multiple times, you'll see that it returns different IP addresses, because std/fetch uses proxies so that each request is made from a different IP address. 📝 Edit docs
