Inspect pending commands?

[assembrix-itamar-zwi]

Motivation

I am trying to debug a problem in our server where calling redisClient.close() hangs indefinitely. For that, I would like to inspect which commands are still pending, but there doesn't seem to be an API that exposes that

Basic Code Example

// Example: inspect pending commands before closing
const pending = redisClient.getPendingCommands();
console.log('Pending commands:', pending);

// Close after inspecting
await redisClient.close();

// Another example: optionally wait for pending commands to finish
await redisClient.close({ timeout: 5000, logPending: true });

Hi @assembrix-itamar-zwi, thanks for the suggestion! At the moment this isn’t something we’re likely to prioritize. The use cases seem quite limited, and it’s also straightforward to implement this kind of tracking outside of the library if you need it. For example:

const pending = [];
const client = createClient();

function wrapCommand(cmd, ...args) {
  return new Promise((resolve, reject) => {
    pending.push(cmd);
    client[cmd](...args)
      .then(r => { pending.splice(pending.indexOf(cmd), 1); resolve(r); })
      .catch(e => { pending.splice(pending.indexOf(cmd), 1); reject(e); });
  });
}

// Usage
await wrapCommand("set", "foo", "bar");
console.log("Pending:", pending);
await client.quit();
