A modal is a popup that when appears on the screen we cannot interact with any other element on the webpage apart from the modal.
On other hand a dialog is a popup that when appears on the screen we can still interact with other element on the webpage




By default a dialog element will be hidden unless you add the open attribute to your dialog


Code

You can see me


It is not advised to use the open attribute directly, though, as that only allows you to open a non-modal dialog. Instead, you should use the show() and showModal() JavaScript methods.


Code

const dialog = document.querySelector("dialog")
dialog.show() // Opens a non-modal dialog
dialog.showModal() // Opens a modal


To close a dialog element you just need to use the close() method.
Alternatively, if your dialog element is a modal you can use the Esc key to close it.


Code

const dialog = document.querySelector("dialog")
dialog.close() // Closes the dialog

When we have conflicts between main and production, we cannot open PR directly. We do the following:
1. git fetch and then go to production -> git checkout production
2. Create a new branch from production -> git checkout -b
3. Pull latest changes from main -> git pull origin main or git merge main
4. Resolve conflicts
5. Push the changes and create a pull request with base branch as production
6. And chill 🙂

Code

git reset --hard origin/master
says: throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master.

You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".

So if we want to mock the useRouter hook in NextJs, we can use vi for it.
The "vi" library's function vi.mock allows us to simulate the behaviour of the useRouter hook. The mock function returns an object that mimics the Router object's properties and methods.


Code

vi.mock("next/router", () => ({
    useRouter: () => ({
      replace: vi.fn(),
    }),
  }));


replace: a mock function that simulates the behavior of the replace method of the Router object.
If we do not use it, the test might fail and we get the following error.
Error: NextRouter was not mounted.

userEvent is considered to be a more reliable and secure way of triggering events in the browser because user events are events that are triggered by a user's interaction with the webpage and reflect the actual user behavior on the page.
However, fireEvent is a means of programmatically activating an event (dispatching DOM events) in the browser, which can be less dependable.

userEvent is more reliable and easy to use rather than fireEvent.
userEvent provides wide range of browser events options and it is like interacting with events same as we interact in browser
