I'm trying to download a potentially large file by streaming. It must be accumulated into memory because the API I'm using requires a base64 upload. However, I'm thinking a stream might still be necessary because the implementation would be in a web server and I don't want to block the event loop. Any ideas on why this code might not be working? It seems like the chunks aren't being concatenated because I'm getting only the first piece of the response body when I debug. import { Transform } from "stream"; import axios from "axios"; import fs from "fs/promises"; class Base64EncodeStream extends Transform { private completePromise: Promise<string>; constructor() { super({ transform: (chunk, encoding, callback) => { this.push(chunk.toString("base64")); callback(); }, }); this.completePromise = new Promise((resolve, reject) => { let data = ""; t

I am trying to build an API with API gateway to accept a file upload. I am going through lambda so that I can manipulate the file name before passing it on to S3 bucket In the event body i can see the file contents but can't seem to access the file name. Right now Im not implementing anything to move file to S3 because I haven't been able to access the file name. the code is as follows import sys import os import boto3 import json def lambda_handler(event,context): eventBody = json.dumps(event['body']) return { 'statusCode': 200, 'headers': { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' }, 'body': eventBody, 'isBase64Encoded': False } the event body looks as follows "----------------------------210938299122441198584130\r\nContent-Disposition: form-data; name=\"file\"; filename=\"test.txt\"\r\nContent-Type: text/plain\r\n\r\nthis is a test f

I'm working on my first react project and I have an upload button through which the user can upload a set of files. I noticed that the file upload works perfectly for all file extensions, except for .json files.

I am trying to add rows for search/filter requirement. There are 100s of fields to filter. Do my boss decided to keep them in a dropdown (here in this example I kept Manager, City and Name). When user selects one from the drop down, (lets say, City), the next box should display another drop down with all cities. If user selects Name, the next box should display a Text Box. And user can add as many rows (filters). I tried and was able to dynamic add rows and display text box or drop down (based on inputType). But my problem is when I change from manager to Name, then it changes all boxes in right side to Text box. And when Add a new row/filer, it automatically displays previous selected drop down or Test. That means what I want is the right side dropdown or text box should appear only when user selects a value from the left side. I am not sure I am explaining it well or not. But please feel free to ask questions. Below is the example I have done so far. Thanks in advance for your hel

I've encountered a problem, probably it's not something huge. So basically I'm using Google Drive API to retrieve files from drive and I want to make pagination, I managed to do next page just fine, but the problem rised when I tried implementing Previous Page button. Imanaged to make it work, but now if there's 2 pages it works just fine, but if there's more than 2, for example, if there are 3 pages, if I go to 3rd page, click Previous Page button, it takes me to 2nd page, but then there's no "previousPageToken" so button is not appearing at all.

I am trying to create a regex expression which will allow the test string to match with the following conditions: The test string can be any length and contain any letters. ALL characters in the regex must be matched. All letters in regex must be matched ONLY the number of times they are repeated in the regex expression. If a letter is repeated more than once in the regex it can be consecutive in the test string or separated by other letters. The letters in the test string don't have to be in the same order as the regex.

I have a set of lists composed of names and role. However, there is no real logic between how the list are organized. For instance, I have this list : l = ['john', 'owner', 'mark', 'manager', 'alex', 'steve', 'employee', 'manager'] #the last role shouldn't be assigned to anyone I want to assign each person the role that is located next to it in the list or the closest one from left to right. The desired output should be something like : output = [['john', 'owner'], ['mark', 'manager'], ['alex', 'employee'], ['steve', 'employee']] My guess was to add indexes to the list elements, and than check which element based on a set of condition was closest to the list element I was looking at. This is part of my script : parties_role = [(idx, item) for idx,item in enumerate(l)] for item in parties_role: if "owner" not in str(item[1])

I have a script that creates a <span> every 1,000 ms, adding it to a <p> element through its appendChild function. The transition for opacity for these spans is set at 3,000 ms, and I have a setTimeout that changes the opacity from its initial value of 0.3 to 1.0 after 10 ms, i.e., right after the element is added it begins transitioning. The issue I'm having is that once a new <span> is added to the <p> any currently animating element skips its transition til its end, suddenly arriving at the final 1.0 value. Why is this happening? Can't I add an element to a container without messing with currently running transitions? const text = `This is just an example`; const words = text.replace(/\n/g, ` `).split(` `).filter(i => i); let i = 0; function add() { const container = document.getElementById('container'), span = document.createElement('span'), id = `s${i}`; span.innerText = words[i % words.length]; span

how to filter for different value for each object and is there is a better way to validate that amount of sales items wont be bigger than purchases items here is what I think is wrong in SaleItemListSerializer I am making a for loop and for each item I get its medicine and expiry date then finding sum by making 2 subquery and a query so if I have 15 item there will be 15 query on the database the total response time is in average about 0.8 s in sqlite but in mysql it grows to 1.5 ( still i want to add retrived items and disposed items in the supquery so it will grow bigger ) so is there is a way to annotate all medicine that are in items each with its expiry date ( which is stored in sale items and purchase items ) in one database query ?

I have storage container where data is in multiple folders with date appended at the end.

For that I pull all data and then use temp view to filter based on folderLoadDate which one of the column in parquet files.

I use the AppState API listener to run a function when the app comes from background to active state.

I need to fetch json data and iterate over it, fetching some more json data later, and finally setting React states. I'd like to use a general function to handle all file requests. I'd also like to handle different types of errors ( 404 and json parsing, mostly). I've read How to use async functions in useEffect and several other relevant articles, but whatever I try to do outside of my fetchData function, I keep getting only Promises instead of data. Also, this only needs to be done once, when the main App.js load. Is it good practice to use an Effect for that, or should it be done at the top of the file, before the App component itself (which needs the data)? useEffect(() => { async function fetchData(url) { const response = await fetch(url, { headers : { 'Content-Type': 'application/json', 'Accept': 'application/json' } }) if (!response.ok) { return Promis

I have this URL , and when it opens it loads up a table dinamically using JavaScript. I looked into the network tab while the page is loading, and found out that there is a GET request to get a JSON file for the table, which pings the /fnet/publico/pesquisarGerenciadorDocumentosDados route with some extra queries. Most of them are the same for any cnpjFundo , but there are two queries I'm having trouble finding where they come from: administrador and _ . Is there a way I can find where the website is pulling these values from? I've tried looking through some of the js scripts, but I can't make sense of anything.

This is a really simple question, I'm building a timer in React JS and I want to know if this is right. There is a setInterval() on my app that every second decreases 1 to my "seconds" state, which is this one: const [seconds, setSeconds] = useState(0) const [minutes, setMinutes] = useState(0) const [isPaused, setIsPaused] = useState(true) timerId.current = setInterval(() => { setSeconds(prev => prev - 1) }, 1000); And this useEffect checks EVERY SECOND if the timer is running AND if seconds is < than 0, to increase minutes and adds 59 more seconds. useEffect(() => { // if timer isn't running return if (isPaused) { return } // reset seconds and decrease minutes if (seconds < 0) { setSeconds(59) setMinutes(prev => prev - 1) } }, [seconds]) My question here is, isn't it bad for the useEffect to run two if statements every second? Like, wouldn't it be bad for performance? And if it reall

Hello all and thank you for any assistance in advance. I am using the astropy circmean function ( https://docs.astropy.org/en/stable/api/astropy.stats.circmean.html ) to evaluate the weighted circular mean of an array of angles. The function takes a numpy ndarray for the angles in radians and another ndarray for the weights. I am getting a type error when trying to input a numpy array for the weights. I can reproduce the error with this code: import numpy as np from astropy.stats import circmean circmean(np.array([.05, -np.pi/2, np.pi]), np.array([1, 1, 10])) Error: TypeError: only integer scalar arrays can be converted to a scalar index I tried checking that the arrays were the required data type and changing the data type of the weights entries. The function works without the weights, but I need to use the weighting. I was expecting the function to work and calculate the desired weighted mean. source https://stackoverflow.com/questions/76309526/astropy-weighted-circular-mea

I am learning javascript. I find that variables can be declared using var or let . However, I also find that the code works well even if variables are used without any of these 2 keywords. Hence, I can use any of following: name = ""; var name = ""; let name = ""; Why should I use var or let if they are not essential? Thanks for your insight.
