54-59: Approve changes with a minor suggestion for improvementThe modification correctly addresses the PR objective by changing the
urlsvalue to a string instead of an array. This aligns with the WebRTC specification and simplifies the response structure.Consider further simplifying the response structure by removing the outer array, as it's no longer necessary with a single ICE server:
- return new Response(JSON.stringify([{ urls: stunDomain }]), { + return new Response(JSON.stringify({ urls: stunDomain }), { headers: { "content-type": "application/json;charset=UTF-8", "Access-Control-Allow-Origin": "*", }, });This change would make the response even more straightforward while still adhering to the WebRTC specification.

38-41: Enhance error responses with informative messagesWhile the current error handling covers basic cases, it could be more informative to help with debugging and client-side error handling.
Consider modifying the error responses to include descriptive messages:
if (request.method !== "GET") { - return new Response(null, { status: 405 }); + return new Response(JSON.stringify({ error: "Method Not Allowed" }), { + status: 405, + headers: { "content-type": "application/json" } + }); } if (requestUrl.pathname !== "/webrtc/ice_servers") { - return new Response(null, { status: 404 }); + return new Response(JSON.stringify({ error: "Not Found" }), { + status: 404, + headers: { "content-type": "application/json" } + }); } if (!request.cf) { - return new Response(null, { status: 400 }); + return new Response(JSON.stringify({ error: "Bad Request: Missing Cloudflare metadata" }), { + status: 400, + headers: { "content-type": "application/json" } + }); }This change would provide more context in error scenarios, aiding in troubleshooting and improving the API's usability.

54-59: Add error handling for JSON stringificationThe current implementation doesn't handle potential errors that could occur during JSON stringification. While unlikely, it's a good practice to handle such cases.
Consider wrapping the response creation in a try-catch block:
- return new Response(JSON.stringify([{ urls: stunDomain }]), { - headers: { - "content-type": "application/json;charset=UTF-8", - "Access-Control-Allow-Origin": "*", - }, - }); + try { + return new Response(JSON.stringify([{ urls: stunDomain }]), { + headers: { + "content-type": "application/json;charset=UTF-8", + "Access-Control-Allow-Origin": "*", + }, + }); + } catch (error) { + console.error("Error stringifying response:", error); + return new Response(JSON.stringify({ error: "Internal Server Error" }), { + status: 500, + headers: { + "content-type": "application/json;charset=UTF-8", + "Access-Control-Allow-Origin": "*", + }, + }); + }This change ensures that any unexpected errors during response creation are caught and handled gracefully.

42-42: LGTM: Test assertion updated to match new ICE Server config format.This change correctly updates the test assertion to expect a string value for the
urlsproperty instead of an array. This aligns well with the PR objective of fixing the WebRTC ICE Server config format.
Despite the
urlsbeing plural in the response, the value should be a string, not a list.Summary by CodeRabbit
