Drupal 8.x

hi, 

everything is in the title, I want to create a button that refreshes the page. I've checked on internet, but it's absolutly unclear to me mostly because I don't know how to integrate Javascript within a drupal 8 module. 

I guess other people's have being througth that. Could anyone of them help me ? 

cheers

Hello, I want to do a very basic query in my my_module.module  but i can't solve it. Someone could help me ?

I want to make an update of my table only for the more recent entry for a specified user. In sql, something like this :

UPDATE table
SET used = 'false'
WHERE bid = (SELECT MAX(bid) FROM table
WHERE uid = 1)

But I don't find any way to do this in drupal 8.

Thanks in advance.

PS: sorry for my bad english

Hi,

I have tried to create a view named Aricles(should have been Articles) which displays all contents of type articles. I have attached a link that shows the screenshot. GET request is giving 406 error, if I type http://some_address/api/articles. 

But if I type http://some_address/api/articles?_format=json, it displays the content. Is there a way not to type that ?_format=json everytime . Can you please let me know. 

Here is the link, Aricles is right on top:
