I'd like to query out the structure. I tried this and a few other variants of it to no avail:

LINE 3: jsonb_array_elements(work_experience) workexp;
    ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

Everything I look up has documentation on traversing and querying jsonb rows, but not jsonb[] ones. How can I query for the "skills"."id"s?

EDIT -- SOLUTION: All of the solutions given were helpful but I selected Ramin Faracov for suggesting to use unnest. Thank you!

This is the query that I came up with:

SELECT
    id expert_id,
    we_sk->>'id' work_exp_skill_id
FROM (
    SELECT 
        id,
        unnest(work_experience)->'skills' we
    FROM foo_json
) sk,
jsonb_array_elements(sk.we) we_sk;

Answered 2022-Apr-09 at 06:24

In PostgreSQL all jsonb array functions only for using JSONB types, not JSONB[].

First-way you can use unnest function to convert arrays to rows, after then you can use jsonb_array_elements.
Second-way change type JSONB[] to JSON in your table. Don't worry, you can still insert your JSON string data which is written above into JSONB field without any problems. Inside the JSON and JSONB strings, we can use arrays using formatted strings. Jsonb array functions only for arrays written inside JSON string.

QUESTION

Is there any way to crop videos in JavaScript with a crop box, without using React or Vue?

Asked 2022-Mar-11 at 15:51

I was trying to crop videos with cropper.js, but from what I understand that it is impossible and only works for photos. I've looked everywhere for resources to do such, but I couldn't find anything. If you don't know what I am talking about I would like something like this https://codesandbox.io/s/react-easy-crop-for-videos-lfhme but uses JavaScript instead of React. The reason I don't want to switch to a frontend framework is because I am using Django for my backend, and am not comfortable with switching to APIs, and using React or Vue, since I am really far into my project. I also want to avoid using a hybrid architecture if possible. If anyone knows of any libraries or repositories I can check out that might help me that would be much appreciated.

Just in case I can use videos in cropper.js here is my source code.

    // file-box is the id of the div element that will store our cropping file preview
    const filebox = document.getElementById('file-box')
        // crop-btn is the id of button that will trigger the event of change original file with cropped file.
    const crop_btn = document.getElementById('crop-btn')
    // id_file is the id of the input tag where we will upload the file
    const input = document.getElementById('id_file')

    // When user uploads the file this event will get triggered
    input.addEventListener('change', ()=>{
      // Getting file file object from the input variable
      const img_data = input.files[0]
      // createObjectURL() static method creates a DOMString containing a URL representing the object given in the parameter.
      // The new object URL represents the specified File object or Blob object.
      const url = URL.createObjectURL(img_data)

      // Creating a file tag inside filebox which will hold the cropping view file(uploaded file) to it using the url created before.
      filebox.innerHTML = `<img src="${url}" id="file" style="width:100%;">`
      // Storing that cropping view file in a variable
      const file = document.getElementById('file')

      // Displaying the file box
      document.getElementById('file-box').style.display = 'block'
      // Displaying the Crop buttton
      document.getElementById('crop-btn').style.display = 'block'
      // Hiding the Post button
      document.getElementById('confirm-btn').style.display = 'none'

      // Creating a croper object with the cropping view file
      // The new Cropper() method will do all the magic and diplay the cropping view and adding cropping functionality on the website
      // For more settings, check out their official documentation at https://github.com/fengyuanchen/cropperjs
      const cropper = new Cropper(file, {
      autoCropArea: 1,
      aspectRatio: 1/1,
      viewMode: 1,
      scalable: false,
      zoomable: false,
      movable: false,
      minCropBoxWidth: 200,
      minCropBoxHeight: 200,
      })

      // When crop button is clicked this event will get triggered
      crop_btn.addEventListener('click', ()=>{
        // This method coverts the selected cropped file on the cropper canvas into a blob object
        cropper.getCroppedCanvas().toBlob((blob)=>{

          // Gets the original file data
          let fileInputElement = document.getElementById('id_file');
          // Make a new cropped file file using that blob object, file_data.name will make the new file name same as original file
          let file = new File([blob], img_data.name,{type:"file/*", lastModified:new Date().getTime()});
          // Create a new container
          let container = new DataTransfer();
          // Add the cropped file file to the container
          container.items.add(file);
          // Replace the original file file with the new cropped file file
          fileInputElement.files = container.files;

          // Hide the cropper box
          document.getElementById('file-box').style.display = 'none'
          // Hide the crop button
          document.getElementById('crop-btn').style.display = 'none'
          // Display the Post button
          document.getElementById('confirm-btn').style.display = 'block'

          });
        });
    });

Answered 2022-Mar-05 at 20:48

You didn't explain your use case in much detail, but if you just want to crop videos with a few known aspect ratio options, you can do this pretty easily do this with vanilla HTML, CSS, and JavaScript.

HTML:

<div class="crop-container aspect-ratio-16x9">
   <video id="the-video" autoplay>
       <source src="https://vid.ly/5u4h3e?content=video" type="video/mp4">
   </video>
</div>

CSS:

.crop-container {
    overflow:hidden;
    display:flex;
    align-items: center;
    justify-content: center;
    height: 0;
    position: relative;
}

.crop-container video {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  height: 100%;
}

.aspect-ratio-16x9 {
  padding-top: calc(9 / 16 * 100%);
}

.aspect-ratio-4x3 {
  padding-top: calc(3 / 4 * 100%);
}

The aspect ratio is always the height divided by the width * 100%.

And then you can apply the the classes however you want, for example:

function switchAspectRatio(ratio) {
  const el = document.querySelector('.crop-container');
  
  // Remove any previous aspect ratios
  for (let i = el.classList.length - 1; i >= 0; i--) {
      const className = el.classList[i];
      if (className.startsWith('aspect-ratio-')) {
          el.classList.remove(className);
      }
  }
  
  // Add the new one
  el.classList.add(`aspect-ratio-${ratio}`);
}

Here's an example fiddle.

How do I move an image background inside of a container, without moving the container itself?

Asked 2022-Jan-30 at 01:32

I have a container being used to hold a registration form. I tried adding position: relative then using top: combined with a negative integer to move the image, but what happens instead is that the entire container is being moved, rather than the background image. I am using bootstrap as a frontend framework.

.mt {
  margin-top: 25px;
  margin-bottom: 25px;
}

.reg-bg {
  background-image: url("../img/reg-bg.png");
  background-repeat: no-repeat;
  border-radius: 15px;

.reg-btn {

ANSWER

Answered 2022-Jan-30 at 01:32

The first point is to try not to use negative position value in your CSS code as much as possible. It's kind of dirty code and may cause some issues in styling later!

Why don't you use background-position to set the position of the image background?

as an example:

.reg-bg {
  background-position: top center;
}

How to host a React app in Nodejs without using Express?

Asked 2021-Dec-19 at 20:00

I know the standard way is to use Express, but i was wondering how i could achieve this without having to use it. I already know how to serve html files using http/https in a common website (without a frontend framework) through nodejs, but when i tried to do the same with index.html from React app, it wouldn't work. I think it's important to mention that i am using react-router. I searched a lot about this but every tutorial would use Express, so i couldn't find help in google.

Here's how i would do with plain html:

const server = http.createServer( async (req, res) => {

res.statusCode = 200;
res.setHeader('Content-Type', 'text/html');

const requestUrl = url.parse(req.url);
let completePath = requestUrl.pathname;
let path = completePath.split('/').slice(1)[0];

let fileContent;

if(path == "")
    path = "index.html";

try{
    fileContent = fs.readFileSync(path);
    res.end(fileContent, 'utf-8');
}
catch(err){
    console.log("File not found: " + path);
    if(path != "favicon.ico"){
        res.statusCode = 404;
        fileContent = fs.readFileSync("404.html");
        res.end(fileContent);
    }
}


});

Thanks!

Ok, i eventually got it:

const fs = require('fs');
const https = require('http');

const hostname = 'localhost';
const port = 3000;


const server = https.createServer( async (req, res) => {

    res.statusCode = 200;
    let root = "./build";

    let path = root + req.url;

    let fileContent;

    if(path == root + "/")
        path = path + "index.html";

    try{
        fileContent = fs.readFileSync(path);
        res.end(fileContent, 'utf-8');
    }
    catch(err){
        if(req.url != "/favicon.ico"){
            fileContent = fs.readFileSync(root + "/index.html");
            res.end(fileContent);
        }
    }

});

server.listen(port, hostname, () => {
    console.log("Server listening on " + port);
});

as opposed to Express version:

const express = require("express");
const app = express();

// this throws everything to the user
app.use(express.static(__dirname + "/build"));

// this redirects everything to index.html
app.get('*', (req, res) => {
    res.sendFile(__dirname + "/build/index.html");
});


app.listen(port, hostname, () => {
    console.log("Server listening on " + port);

Javascript Dynamic Data binding code not working

Your main issue is this part:

const bindings = Array.from(document.querySelectorAll('[bit-data-binding]')).map(
    e => e.dataset.binding
  );

or more specifically e.dataset.binding. Your elements do not a have data-binding attribute, which would be the prerequisite for using dataset.binding. You can use e.getAttribute('bit-data-binding') instead.

But your logic is also flawed: As it currently stands, entering text into an input is pointless, as the state is never updated.

Finally, note that you spell LastName with a capital L in your DOM but lowercased in your state object.
