...ANSWER
Answered 2022-Mar-23 at 21:58If you haven't specified the type of module in your package.json, it will default to CommonJS. In this context, you cannot use the import syntax, you have to rely on require.
There are 2 ways to resolve this:

QUESTION
What I would like to do, is to use dropzone.js as a drag&drop zone.
I don't want to upload the files, what I would like is to be able to access them and process them with jszip on the browser level (no server scripts, ajax etc.) using vanilla javascript.
I know how to process files from an field, but I would like to combine this with DropZone.js as it is more user friendly (able to add/remove files, see thumbnails etc.)
The documentation is not very clear on the events to use, could someone give me a hand or a guiding direction?

QUESTION
I'm working on an application with Angular 12, which allows users to store a heavy files, like images, and videos. (There are videos that could be larger than 1GB). Anyway, they are very heavy files.
In this application, it's necessary to place a button "Download everything as ZIP" the problem is that the way I currently have to handle this download is with JSZip and it makes my computer very slow, also it does not report the progress until the file is armed zip, that is, it spends 20 minutes at 0% download and even later it begins to report the progress.
This is the solution that I am currently implementing:

QUESTION
I am new to Web3 and I am trying to create a react app integrated with web3. Below are the steps I followed in Ubuntu.
...ANSWER
Answered 2022-Jan-23 at 09:25That is because Webpack 5 no longer does auto-polyfilling for node core modules.
Simply in order to modify the webpack.config.js in Create React App, you have to run
npm run eject
this will create a config directory and inside you will have webpack.config.js.
QUESTION
I want to store several blobs from canvas elements using canvas.toBlob function to an array.
I've tried the code below which was useless. The result showed that the .toBlob() function works like an async function, and I have no knowledge about it.
ANSWER
Answered 2021-Dec-17 at 07:26The result showed that the toBlob function seems like an async function, and I have no knowledge about it.
Yeah, toBlob() accepts a callback, and you're using it now in your code. But, we can easily clean this up using async, await, and Promises. I would do this all in the same loop. Untested code, but try something like this:

Answered 2021-Sep-13 at 07:06you haven't provide full example of your code, so I can't run it, but it looks like:
You've created folder examples, you've put a file into it, and then took pure zip object, and saved it as example.zip;
PS: Pay attention, that you are calling examples.file and zip.generateAsync asynchronously, what may cause another issues. I would recommend you put your zip.generateAsync inside ddPdf.getBlob callback.
It might be something like:
QUESTION
I've already implemented a dropdown in a grid column according to this demo: https://demos.telerik.com/kendo-ui/grid/editing-custom
I already did a test with this custom dropdown: https://demos.telerik.com/kendo-ui/dropdownlist/addnewitem
I am wondering if it's possible to add this custom dropdown in a column of the grid to add a new category if the category is not found in the dropdown.
The column doesn't show in the column Comment.
I tried the following code without success, some tips of how to solve this?
EDIT 1: I tried the abinesh solution, and I think it is very close to solving this issue(http://dojo.telerik.com/OZIXOlUM). Still, the addNew function expects the widgetID. In the onclick of the add new button, the widgetID is passing nothing (see print screen). How did I get this ID? The script "noDataTemplate" is trying to get the id this way '#:instance.element[0].id#', but as I said, nothing returns.
