• How to create an order from a cart in Mongoose and delete cart

  I am trying to: a) Create an order from my current cart b) Populate the response of the order with the selected object attributes in the "select" c) Finally, I would like to delete the cart.

  I have tried the below but here are my problems:

  1. the result response does not come back populated even if the prevProductsQuantity constant is indeed populated
  2. I created the function cartClear to receive the cart id and delete the document from the model but it is not working.
  3. I am able to create many "same" orders so I think i need to manage with a conditiona but not sure where.

  The response I am looking for:

  I am fetching some data using an api. Inside that api there are SQL queries that are executed. I have api that will be used to fetch data or execute these queries. I want to know how can I replace my chart's static data with dynamic data that will be fetched from api.

• Sort,Filter,search in Javascript array

  Given values for acctData and balances below, write a function that returns only an array of account numbers, and accepts the following optional parameters:

  - user
  - sortBy (accepts "acctNum" or "balance")
  - sortDirection (accepts "asc" or "desc"; default to asc)
  

  2. Execute your function and output the results as an array in console log for the following scenarios:

     a) filtered by Bob b) filtered by Charlie c) sorted by acctNum d) filtered by Alice; sorted by balance ascending

     acctData = [ { "acctNum": "AAA - 1234", "user": "Alice" }, { "acctNum": "AAA - 5231", "user": "Bob" }, { "acctNum": "AAA - 9921", "user": "Alice" }, { "acctNum": "AAA - 8191", "user": "Alice" } ]; balance = { "AAA - 1234": 4593.22, "AAA - 9921": 0, "AAA - 5231": 232142.5, "AAA - 8191": 4344 };

• How to use EC2 Instance Profile in Nodejs application to access AWS Services?

  I have a Nodejs application which runs on an EC2.

  The EC2 has an instance profile attached to it.

  How can I use the instance profile inside my Nodejs code so that my Nodejs code can access AWS Services like S3 bucket etc without using AWS Access Keys?

  I found this link that's close to this topic but could not see any sample code provided there:

  https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/loading-node-credentials-iam.html
• How do I store an array in a PSQL, where it is passed as a parameter $1 to the db query

  I am passing a one-dimensional array of three strings to the function, it looks like this going in:

  [ '#masprofundo', '#massensual', '#eclectic' ]
  

  The data column is declared thus:

   tags TEXT []
  

  This is my function:

  const query = `INSERT INTO posts (posted_at, message, link, tags)
                  VALUES (TO_TIMESTAMP($1, 'DD/MM/YYYY HH24:MI'), $2, $3, ARRAY [$4])
                  RETURNING tags;`;
  const params = [timestamp, message, link, tags];
  

  Now, postgres believes I want to insert an array containing one item, which is a string of all the values in my tags array. It looks like this:

  { tags: [ '{"#masprofundo","#massensual","#eclectic"}' ] }
  

  What I want to know is, how do I prevent this behaviour, where postGres adds an unnecessary extra layer of quotation marks and parentheses? For further clarification; this is what the row looks like in my terminal.

  {"{\"#masprofundo\",\"#massensual\",\"#eclectic\"}"}
  

  I have looked at the docs, and tried a dozen variations on ARRAY[$4]. From what I can see, the docs do not elaborate on inserting arrays as variables. Is there some destructuring that needs to happen? The arrays I pass will be of varying size, and sometimes empty.

  Any help is much appreciated.
