FAQ
Is CSS isolation supported?
It is not supported yet, because sub-applications need to follow very strict conventions to be properly handled, and the following notations can cause problems:
height: 2rem;
:root {
}
:is(html) {
}
:where(html) {
}
Browsers do not currently have the ability to parse css selectors in detail, so there are only two options: (1) implement very simple selector parsing themselves, and (2) introduce a third party, such as css-tree.
Can ESM support sandbox?
It is possible in theory, but lacks practical value, and needs to realize the analysis and operation of ESM by itself.
WARNING
For both ESM and UMD, you should be cautious about opening a sandbox, especially if you have no control over the content of your sub-applications (such as maintenance by different teams).
How to view the execution logs?
Haploid.js relies on debug to log, so you can:
localStorage.debug = "haploid(*):*";
