I'm trying to make a node app that runs on the server. I created a motion detection system in p5 and its library vida.
I first tried global mode. Then I got errors like createCanvas is not defined. Now I tried instance mode, but I feel it has gotten even worse. I get the errors window is not defined in the p5.js script and require is not defined from the p5.dom.js script.
How should I correctly implement my p5 elements in the node app?
I read a.o. this stackoverflow post, but I don't know what it means to run p5 in the browser within a node server.
Here my server.js
...ANSWER
Answered 2021-May-07 at 11:24P5.js is not meant to be used outside of the browser. However, if you must, it can technically be made to work. I've posted an example below (which you can also view and run via my Repl.it project). But beware, there is no guarantee this will work for your use case. Just getting the canvas's image data to write to a file for this example was a humungous pain, so your mileage may vary.

I'm trying to figure out how to test components that update state using useEffect to make an API call to get data. There are several things I think are important to know before I can talk anymore, and that is the files/packages I'm using.
First, I have a main component called App.tsx
, inside App.tsx
, inside of useEffect, I make a fetch call to an external API to fetch an array of songs by Queen. I also render out a component using
.map
to iterate over each song and .filter
to filter songs on UI based on text input. I'm using a custom hook. Here is the code I have for that component and its custom hook.

I am rendering the component in an integration test of my single page app and attempting to follow a happy path from landing on a page to the first question of a quiz / memory game.
...ANSWER
Answered 2021-Mar-23 at 23:09Here are several things you can do:
- The warning tells you that your app continues after your test completed, and thus other things happen during the run that you didn't check in your test and didn't wait for. So if you're happy with what you are testing, be warned and keep it like that.
- You can make your app a bit more testable by giving it options. For example you can have an optional prop indicating the amount of time to wait in timers, so that you can put it to 0 or a small number in your tests.
- You can mock timers:

Answered 2021-Feb-23 at 07:25why my code isn't printing out the elements in the array (AtomNames) in a numbered list
Because you're using ul (unordered list) instead of ol (ordered list/numbered list)
Also you're creating text nodes in this point document.createTextNode(list)
