Graceful Shutdown

If you’re running MTKruto with a persistent storage outside browsers where you can control the behavior of SIGINT, it is recommended that you disconnect the client before the process exits. This way, you’ll make sure that important cache that can later improve the performance of your app is persisted.

Here’s how it can be done.

Deno.addSignalListener("SIGINT", async () => {
  await client.disconnect();
  Deno.exit(0);
});

process.on("SIGINT", async () => {
  await client.disconnect();
  process.exit();
});

How to Know If You Need This

If you don’t have the client parameter persistCache set to true, which is false by default, you don’t have to worry about graceful shutdowns at all.

If you use the memory storage adapter, you don’t need this regardless of what you set persistCache to.
