QUESTION
I'm facing this issue in this Vite started repository.
https://github.com/vicainelli/vite-starter
I'm using Vite + Preact + Vitest + Testing Library
If I'm testing any code inside the codebase, it works fine, but If the test runs against some component that uses another component from an external library, I'm getting this error.

QUESTION
When I try to start my Preact app using npm start it gives this error
...ANSWER
Answered 2021-Dec-30 at 14:20It's been deprecated, and is true by default now.
You can't use inline option (it will be always true in next major).

I couldn't find anything more authoritative about the change
QUESTION
I'm using Preact with styled-components (storybook) and webpack to build my project
I have a component called AlphaBarWrapper with a styled component inside of it called StyledAlphabar.
Styled Components is adding AlphaBarWrapper_StyledAlphaBar-sc-[random string] as a classname to my component when rendered.
I'd like this to be the standard sc-[random string] class name instead. I can't find any documentation on why it is rendering this.
This occurs in both a standard webpack build and the storybook build, so I expect that there's an option that I'm missing.
...ANSWER
Answered 2022-Mar-16 at 13:21If i'm right understood your issue you need install babel-plugin-styled-components. Then in the root directory create .babelrc and put this code:
QUESTION
I've recently switched my CRA dictionary application to Preact using craco. I've made this work using webpack aliases, which replace references to react packages with preact packages (e.g. preact/compat).
craco build
I get no errors and the build successfully completes, and you can see the folder here:
Everything fine here.
craco start
It starts the predeployment checks (I think), and hits a snag very quickly. It can't find the react module.
...ANSWER
Answered 2022-Feb-16 at 16:40You need to keep react installed, unfortunately. It's required by react-scripts for starting the dev server and is unavoidable without forking the package.
If you're concerned about the alias working with React still being installed, you can comment out your config and compare build sizes. You should see a sizable difference, confirming your alias works as intended.
QUESTION
I'm building a widget.
I read it somewhere
"not to use preact-router, because it adds event listeners to all anchors on document level, which is not acceptable for a widget (remember not to mess with the hosting page)".
I want to just get the current URL and no other data is required. How can it be achieved?
P.S: I'm new to programming. Any help is appreciated.
...ANSWER
Answered 2022-Jan-26 at 18:20If all you want is the current URL then window.location does the trick.
QUESTION
I've been playing with wmr and preact-iso and coming from preact-cli, preact-router, etc, I'm a bit confused on how to do some of the things I used to be able to do.
Case in point: preact-router's route() function seems to be missing from preact-iso's router package.
How would I route from code?
I used to be able to do this:

Answered 2022-Jan-18 at 21:19route() exists upon the useLocation hook.
QUESTION
I decided to move my react hobby project from react to preact and struggling with the documentation. Most of the information I got was either from the existing examples or issue discussions on the github.
But what still didn't find is the info on ejs variables used in the template html file.
Is there a good explanation what variables there are by default and how to manage them?
...ANSWER
Answered 2022-Jan-09 at 06:31There's not much of use that's there by default, as this is instead a method of allowing you to inject your own values. If you want to see what's there by default, you can add the following to your template.html:

ANSWER
Answered 2021-Dec-25 at 01:14Using .babelrc isn't supported at the moment in Preact-CLI, though this is due to an odd bug that I haven't yet been able to track down. Sorry about that.
You do however still have a way to edit the Webpack config, and that's with your preact.config.js, the docs for which can be found here. In your case, what you'll want is the following:
preact.config.js
