  • Not only is it possible to write bindings to a native Node.js addon, which are non-blocking / asynchronous, you can furthermore easily make use of multiple threads to perform computionally heavy tasks in parallel and in the next few minutes I am going to show you how to do so….
  • If you are not familar with this syntax: “: Nan::AsyncWorker(callback)” don’t worry, this just means: call the constructor of the superclass with callback.The Execute function will obviously perform the main work of our task, thus we are calling our delay function here.
  • But first of all, we will wrap the async function binding in a Promise, since we would have to invoke it with a callback otherwise, which is very inconvenient once you make multiple asynchronous calls:In case you are not familar with Promises: Promises are basically a convenient way to chain…
  • Thus doAsyncStuffPromised returns the Promise that resolves when our doAsyncStuff holds a result and rejects if an error occured.We will define runSync and runAsync to run our sync and async bindings a few times respectively and log the execution time with the synchronous version we just call the function numTasks…
  • Well the first thing we can see is, that it took much less time to execute the asynchronous tasks, more precisely the async tasks finished roughly 3 times creating a new AsyncWorker will spawn a new Thread.

  • Password cracking is equivalent to picking the lock on the front door of a house to break in, by @ChetanKaradeThis is a note about Node.js security, by reading the amazing book Securing Node Applications by @ChetanKarade, which explains couple of common vulnerabilities in very simple way, and provides relevant npm…

  • Node 8 introduces the Inspector API, which better integrates with existing developer tools.There’s one common theme that I’ve encountered when using these methods: they must be invoked when starting the node process.
  • The other day, I found myself with a process in an odd state that I’ve had trouble reproducing, and I didn’t want to risk losing it by restarting the process to enable the inspector.However, I found a solution — no less, a solution from the official Node docs.A Node.js process started without…
  • This is the SIGUSR1 that the node docs are referring to, so now I just need a pid, or process ID, to send it to.
  • But I see down towards the bottom the right process: node .
  • $ kill -usr1 9713It runs with no output, but I check the logs of my node process and seeDebugger listening on help see can open chrome://inspect, and I immediately see my inspect target.I click “inspect”, and I’m rewarded with a Chrome DevTools window in the context of my node process!…

  • Make sure you have started MySQL on default port and changed the parameter in above code then run this code using – – Above code is just for learning purpose and not for production payload.
  • In production scenario is different, there may be thousands of concurrent users which turns into tons of MySQL queries.
  • In Node mysql, we can use pooling directly to handle multiple connection and reuse the connection.
  • We have created 100 connection limit in code, so you might be wondering that after 100 concurrent connection code will break.
  • If your MySQL server is configured to handle such traffic at one socket then it will run and our code will manage the scheduling of concurrent connection.
