Improving the way of saving posts on while writing.

Yesterday, while I was writing a post which took me 45 minutes to finish, someone from my family came and accidentally pressed the back button of my browser. At that point, I did not understand the consequence and I thought if I will go forward all of the content written will be there. Unfortunately, this is not the case for sites like Hashnode and

Shocking Period

After returning back to the page where I was writing my post I saw what you'll normally see when you click on write a post button. A page with no content. That is when I first get the sense something terrible has happened. For confirmation of the catastrophe I refreshed the page and after that, I started crying inside.

All of the work that I have done for 45 minutes was gone. 😠

Current Solution

At the current scenario, to save your post periodically you will have to click on save post every time you want to save the current state of your draft. I certainly understand why the platform creators have chosen this way of implementation. Two simple reasons are there:

  1. Reduce server load time and therefore...
  2. Reduce server bills

Well, we can certainly go this way of implementation but I think there is a better way to do this.

My Solution

localStorage is one way to improve it. localStorage is a key/value Web Storage API. In which we can store the data of our post. The best part of localStorage is that data in it persist even after tab close or refresh.

Since uses React my implementation is React specific but the general idea will be the same for other frameworks on other platforms. The implementation is on Codesandbox and you can view it from the link below.

Edit Stateful Content

At initial render, I'm checking whether there is some content already present or not. If there is, set the value of textarea to the previously saved value.

  React.useEffect(() => {
    const content = localStorage.getItem("content") || "";
  }, []);


The handleChange function:

  function handleChange(event) {
    const value =;

Every call to setContent will trigger useEffect hook which throttles setting the value of our content in the localStorage. While throttling is not necessary but instead of localStorage if there would have been an API then throttling definitely make sense in that case.

const throttled = throttle((content = "") => {
  localStorage.setItem("content", content);
}, 500);

  React.useEffect(() => throttled(content));

Yes, there are some corner cases that I hadn't covered in this implementation for the sake of keeping this post simple.

Please let me know @ben about your thoughts on this and how can we improve?

This is a very interesting proposal. It's so simple that I'm now wondering why this has not become a feature yet.

@ben Any thoughts on this?

Thanks, @somedood you liked the proposal. I definitely want to hear what @ben thinks about it.

You're right, the editor would be better with some sort of autosave capabilities.

@aspittel is working on it ;-)

This is a very nice feature to have, I've used it multiple times on my phone already (I primarily use on my phone), so I guess it's either implemented for the mobile version of the website, or my phone browser does it automagically.
