Mess with nested loops and async functions in Node.js repl

[entcode]

Hi Replit Community!
I’m working on a Node.js repl at the moment and now I’m trying to get all users’ actions on the server side, sort them by date, and send the first 6 actions to client (as a response to client’s request). The only problem I’m facing is a nested-structure inside a nested structure, involving two for-loops (or any other loop that can iterate through arrays, and is async-friendly) and two async functions to get data from Replit’s built in database.
When running the code below, I end up returning an empty array (given_data). A small research has shown that such happens because of async functions, which run after I send the response (as I mentioned before, the response appears to be an empty array). My attempt of adding .then() instructions failed because of nested code.

Is there a way to solve this problem? Maybe I should somehow split the whole procedure into smaller pieces to avoid nested constructions? My attempts and actions’ description is shown below:

    var given_data = [];
    var currArt = {};

    db.list().then(keys => {
    for (var i = 0; i < keys.length; i++) {
      db.get(keys[i]).then((value) => {
        for (var j = 0; j < value.actions.length; j++) {
          if (["false", false].includes(value.actions[j].action_hidden)) { 
            currArt = structuredClone(value.actions[j]);
            currArt.author_name = value.name;
            given_data.push(currArt);
          } 
        }
        return given_data
      }) 
    }  // res.json(given_data);
      
    }) 

Here’s the example of an object with user’s data:

   {
     name: 'name',
     email: 'hyhyh@g.yu',
     password: 'coolpass',
     actions: array
   }

(action is an array of objects)

Here’s the example of an action:

  {
    title: 'idk smth',
    today: '16.06.2023',
    fullToday: '16.06.2023 13:08:17',
    image: string,
    header: string,
    type: array,
    content: array,
    author_email: 'q@w.e',
    action_hidden: false
  }

(type and content are arrays of strings)

Thanks!

(action is an array of objects)

Here’s the example of an action:

  {
    title: 'idk smth',
    today: '16.06.2023',
    fullToday: '16.06.2023 13:08:17',
    image: string,
    header: string,
    type: array,
    content: array,
    author_email: 'q@w.e',
    action_hidden: false
  }

here is an example owf haw yuu ken do dis

var given_data = [];

db.list().then(keys => {
  // Create an array of promises for fetching each value from the database
  const promises = keys.map(key => db.get(key));

  // Use Promise.all to resolve all promises concurrently
  Promise.all(promises).then(values => {
    for (var i = 0; i < values.length; i++) {
      const value = values[i];

      for (var j = 0; j < value.actions.length; j++) {
        if (["false", false].includes(value.actions[j].action_hidden)) {
          const currArt = structuredClone(value.actions[j]);
          currArt.author_name = value.name;
          given_data.push(currArt);
        }
      }
    }

    // Return the given_data array after all asynchronous operations have completed
    res.json(given_data);
  });
});

Tenk youk for yu tiem, good bye Ai Hoap Yu anjoy
Don wowwy about mai engelish Ai fail ed my engelish teast.

Anyways yes here is an example of how you can do this goodbye :3

Dude, thank you very much! I’ve been struggling to solve this for like 3 days and now it’s finally working! Thanks again!

By the way, your code comments are clear and descriptive, so don’t worry about your English (which, as I can see, is perfect :3333 )
