QUESTION
I have Single Page Webapp (SPA) that verifies the users as part of the signup process. Part of the verification is to capture a selfie of the user. To this end, I've implemented a version of the following code to get the camera input into a video
element on the webpage, from which I can then sample images into a canvas
.

Answered 2021-Oct-06 at 21:00I posted this question on other services and eventually received a response a user named Ravavyr through a separate Discord channel. The response pointed me to this article which provided an answer.

It appears that iOS Safari needs some more configuration to make it work.
The CodePen linked from the original post has been updated to include the changes that make it work.
QUESTION
I'm stuck on lesson 19 of this course - https://javascript30.com/ - which uses Browsersync to provide access to the webcam.
These are the files I'm working with: https://github.com/wesbos/JavaScript30/tree/master/19%20-%20Webcam%20Fun
Having run npm install
I get this error when trying to run the package that includes Browsersync and none of the URLs below work for me:
ANSWER
Answered 2021-Jun-11 at 10:03The CS50 IDE provides a "cloud-based Ubuntu environment", but that means "localhost" according to the browsersync output you're seeing isn't your localhost ― it's the localhost of that cloud environment.
(And the "External" direct IP access will be incorrect too, since it references a local network that your computer isn't attached to.)
The IDE might provide a way for you to access a server that's running in this way, but I suspect a simpler path is to run the start
script directly on your local machine.

I'm building a fcc-drum machine using React I get the following error when trying to map a data object:
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

QUESTION
I am trying to create a swim image gallery based off of the Flex Panel Gallery from Javascript30 (Repo Link). When trying to display the site in a browser, the images immediately go out of frame and all I can see is the background of the five flex columns on the page.
I am unsure as to why they are pushed downwards out of view in the browser and why the text (which isn't in column orientation) doesn't appear until after I click within the columns.
...ANSWER
Answered 2020-Apr-22 at 09:27By watching the repo site example, you should apply the image background to parent div, like this:
QUESTION
This is from the Javascript30 course. I am making a clock but I want to make the hour hand shorter than the minute hand. The minute hand is currently set to a width
of 50%. I want to set the hour hand to 40%. But when I change the width
to 40%, it seems to rotate from a different origin. Then I changed the transform-origin
to 120% but it seems like it is centered differently?
ANSWER
Answered 2020-Apr-02 at 01:22Since it is absolutely positioned, you can use left
to set it correctly, because when you decrease the width, it's moving to the left.
