Freeze lovelace configuration on load

[thomasloven]

Breaking change

#4851 but with freezing the entire configuration instead of cloning it for each card.

This will break some custom cards, but there's several simple fixes, e.g.:

setConfig(config) {
  config = { ...config };
...

import { deepClone } from "deep-clone-simple";
// https://github.com/balloob/deep-clone-simple

setConfig(config) {
  config = deepClone(config);
...

or

setConfig(config) {
  config = JSON.parse(JSON.stringify(config));
  ...

depending on need and personal preference (besides rethinking the methodology of the card).

I would suggest this as way to copy:

setConfig(config) {
  config = {...config}; // create a mutable copy of the configuration
}

[thomasloven]

That's a shallow copy, though. Isn't it? And ES...5? 6? (non IE)

[bramkragten]

Yes that is shallow, for deep just use the deep-clone from balloob we used before:

Looks good. ok to merge when last comment addressed

[thomasloven]

A bit of an indication of how ready people are for this can be found in thomasloven/hass-config#6

[balloob]

Thanks for going through HACS Thomas. It's not going to be released until 2 weeks from now, hopefully enough time.

[bramkragten]

This will now only freeze the config when there are faulty badges.

[thomasloven]

You're right...
