This was important to use different class name for every Box instance (otherwise class name of all elements will be "MuiBox-root").

Sorry for bothering with force-pushes. Finally fixed issues! |
@ypresto Thank you for working on the problem! It's important. I will soon have a look at it :) |
oliviertassinari this its important, when useStyles its called with props its called two times per render, so the first render don't match with the server any time, and its completely inefficient called more times the same thing. but more important never match with server classes when props its present because the counter its called two times on the client. |
@oliviertassinari what's the status with it ? It's going to be merged some day ? |
@ypresto As we are moving to a unstyled core and adapters for styled-components/emotion/jss, it's probably not worth pushing further. Thanks for the exploration! It could be interesting to move the concern to jss. |
Fixes #16704
Make styled() use filterProps value to generate cache key.
You can use
_useStylesCache: null
option to disable this behavior.It's still 2x slower than useStyles(), but 5x faster than original implementation..! (This benchmark creates 100 Boxes at once)
Limitations:
m={2}
) and non-alias (margin={2}
) props will create different cache.link: true
and updating existing style ifrefs === 1
can solve this.
