be-persistent [TODO]
be-persistent is a behavior/decorator/enhancement alternative to purr-sist.
Example 1: Default settings;
<input be-persistent>What this does:
Stores input's value in session storage (key is based on location within the DOM), but can also be specified.
The syntax above is short-hand for:
<input be-persistent='{
"what":{
"value": true
},
"when":{
"input": true
},
"where":{
"sessionStorage": true,
"autogenId": true,
},
"restoreIf":{
"always": true,
}
}'>Example 2: Store to IDB
<input be-persistent='{
"where":{
"idb": true
}
}'>Example 3: Persist on unload
<div contenteditable=true be-persistent='{
"what":{
"innerText": true
},
"persistOnUnload": true
}'>hello</div>Example 4: Persist innerHTML:
<form
action="https://o2h-cw.bahrus.workers.dev/"
target='[-innerHTML]'
be-persistent='{
"where":{
"idb": true
},
"what":{
"innerHTML": {
"beBeatified": true
}
},
"persistOnUnload": true
}'
be-reformable='{
"autoSubmit": false,
"path": ["", "proxy-to"]
}'

<label>
Proxy to:
<input required name='proxy-to' type='url'>
</label>
<label be-typed be-clonable be-delible></label>
<button type='submit'>Submit</button>
</form>
<div -innerHTML></div>

Example tbd: Criteria [TODO]
<input be-persistent='{
"restoreIf":{
"value":{
"eq": "defaultValue"
}
}
}'>Example 5: Persist to url hash
<input be-persistent='{
"where":{
"idb": true,
"hash": true
}
}'>Precedence
If multiple locations are selected as far as where to persist data, the data is persisted to all of them. But as far as restoring state from the persisted data, which one takes precedence?
If IDB is enabled, and the data is found that, that is what takes precedence. If SessionState is enabled (which it is by default, unless specifically turned off) then it takes precedence. If hash is enabled, it takes the next precedence.
