I'm creating a simple webapp. I have a json file, with some datas I need to be processed using javascript ( using javascript and not python to avoid the post request and the page reloading). I have both the js file and the json file in the "/static" directory of the Flask enviroment. Now, I would like to know how to import the json file. I tried using fetch this way:

fetch("test.json")
  .then(response => response.json())
  .then(json => console.log(json));

But it failed. I tried to read the file via python and the pass it in javascript with the following code:

with open("file.json", "r") as data:
    print(data)

But it said me that that file wasn't found. I also read some other sackoverflow answer, and read Json documentation, without finding anything. Some ideas? Thanks
