In the similar way we attach slots in connectedCallback, we could import the component itself into the the main document. Here is a very crude example of the custom element without shadowDOM. Components with no useShadowDOM decorator and a single default slot don't use shadow DOM. Spinning reel slot. The content from the usage site gets hoisted directly into the location of the slot inside the element's view (while maintaining its binding context to the content site origin).

// Custom Template/Slot without Shadow DOM

// template refers to <template></template>

// context refers to stuff inside <your-custom-element> <span slot='bork'>🍭</span> </your-custom-element>

// overall flow of operation translates to YOUR-HTML = TEMPLATE(CONTEXT)

// a map of all <slot name='bork'> elements, where key is the name attribute, and value the <slot name='bork'> node;

consttemplate=newMap(Array.from(this.querySelectorAll('slot').values()).map(i=>[i.name,i]));

// an array of [[name, element]] where name is the slot attribute of html element <span slot='bork'>🍭</span>

constcontext=Array.from(this.querySelectorAll(':scope > *[slot]').values()).map(i=>[i.slot,i]);

console.log(context)

// traverse context, the list of elements with slot='*' property

// name is taken from context (see above)

// element is the thing we want to replace <slot> with

for(const[slotName,element]ofcontext){

// slot is the <slot name='bork'> referenced by <span slot='bork'>🍭</span> inside your custom element

constslot=template.get(slotName);

// if template had the slot bork, replace the entire <slot name='bork'>*</slot> with <span slot='bork'>🍭</span>

if(slot)slot.parentElement.replaceChild(element,slot);// Syntax: replacedNode = parentNode.replaceChild(newChild, oldChild);

// remove the remove slot='bork' from <span slot='bork'>🍭</span>

// NOTE: THIS IS NON SPEC, YOU SHOULD COMMENT THIS OUT FOR FUTURE COMPAT

// element.removeAttribute('slot');
