"However, exposing API key in the client app isn't the best practice. Alternatively, you can use the auth callback to provide the token needed to establish the connection."🧰 Tools

55-84: Improve Auth Token Fetching in the Ably Client ConfigurationThe new auth callback implementation successfully removes the hardcoded API key and correctly uses asynchronous fetching with
await response.json(). A couple of suggestions:
- HTTP Response Validation: Before parsing the JSON, consider checking whether the HTTP response was successful. This could prevent unexpected issues if the backend returns an error status. For example:
- const response = await fetch(BACKEND_URL, { - method: "POST", - }); - token = await response.json(); // adjust it based on your backend data structure + const response = await fetch(BACKEND_URL, { + method: "POST", + }); + if (!response.ok) { + throw new Error(`Token fetch failed: ${response.statusText}`); + } + token = await response.json(); // adjust according to your backend data structure
- Error Handling: The callback in the catch block correctly passes the error message to the auth callback. Ensuring robust error handling here helps prevent the client from attempting to connect with an invalid or missing token.
Overall, the implementation clearly improves security by preventing direct exposure of the API key.
86-86: Refine Punctuation in the Documentation LinkConsider adding a comma to improve clarity in the sentence. For example, change:
"More about token generation please refer to this documentation"
to
"More about token generation, please refer to this documentation".🧰 Tools
