            how to access a local variable value outside the scope of its function in nodejs
            Asked 2022-Mar-02 at 15:50

            I want to compare the data of two files and for that, I'm reading that file using the fs module but since I want to compare the values so I thought to store the value in an external variable but when I do console.log(budget_details) I get nothing in console. Please someone help. Please point me out if my approach is wrong and if we don't need to do that in nodejs. I'm new to nodejs.

            your code is not asynchronous. Anything with 'on', which takes a function, would indicate that it is event driven. You need something like:

            The second argument to cron.schedule() must be function. You need to wrap the code into a function and export it from the module.

            How to process each row/buffer synchronously when reading a file asynchronously using a stream
            Asked 2021-Dec-20 at 10:25

            as you can see i have a js that takes a .csv and calls an async function for every row (4 different functions iteratively).

            The problem is that I need to wait the end of the function in the i-th iteration before I proceed to the i+1 iteration.



            Answered 2021-Dec-20 at 02:43

            The readStream you are using here is asynchronous, meaning .on(event, callback) will trigger every time a new piece of data is read, independently of any callback triggered. In other words, the execution of the callback function here does not impact this process, it will be ran in parallel, every time event received.

            This means that in case callback was to execute a piece of code that is asynchronous, you may very well end up in a situation where multiple instances of this function may still be running by the time the next read event is received.

            Note: this holds true for any event, including the 'end' event.

            If you were to use async/await on callback if would only make the internal logic of this function synchronous. It would still not impact the rate at which your data is read.

            In order to do so you will want to use both async/await on callback (to make it internally synchronous) and have callback manually pause and resume the read operation happening in parallel.

            You called myString.then(myObj.myFunction). This is changing this keyword from myObj to something else. If you want to keep the context of the this keyword you need to bind this manually or call the function instead of passing it into then callback. Example:

            When specifying file paths in node, generally relative paths are derived from the working directory from where node itself was executed. This means if you execute

            node ./backEnd/index.js

            The actual working directory is whatever directory is above backEnd. You can see this via console.log(process.cwd()).

            If you would like to read a file relative to the current file that is being executed, you can do:

            How to parse CSV correctly for Puppeteer to fill strings from CSV lines to text input on website?
            Asked 2021-Oct-18 at 01:32

            I am trying to learn js/puppeteer and by building a simple web scraper to scrape books info for educational purposes. I am trying to get the web scraper to fill UPC numbers from a CSV file onto the search bar of a book website. I managed to get a the web scraper to scrape the website if I use a single UPC number.

            But I have a CSV with a list of UPCs and would love for the web scraper:

            1. to read the CSV file,
            2. grab the UPC from first line,
            3. search for the UPC on website,
            4. scrape the information,
            5. grab the UPC from 2nd line,
            6. repeat 3, 4

            You can get column names with headers event. csv-parser emit headers event after header row parsed. First parameter of callback function is Array[String] and you can access column names or headers . (more doc)

            Wait until Filestream has finished
            Asked 2021-Jul-15 at 20:05

            I'm trying to figure out how to solve this problem:

            I have a function that reads a csv, saves it to an array and then returns the array. My problem: It always returns an empty array, since the filestream hasn't finished, before I try to return the array.



            Answered 2021-Jul-15 at 20:05

            The convert function is finishing before the getRawCsv function because createFileStream is asynchronous. You can wrap the stream into a promise and then wait for it to finish. I abbreviated you example a bit.
