await init();
var app = new OutconceiveApp();

initial_render()	→ JsValue (VNode)	Renders full VDOM
render()	→ JsValue (Patch[])	Full render and diff

State

Method	Signature	Returns
update_state(key, value)	string, string → JsValue (Patch[])	Set text state, return patches
toggle_state(key)	string → JsValue (Patch[])	Toggle boolean, return patches
get_state(key)	string → JsValue (string)	Read text state
get_state_bool(key)	string → bool	Read boolean state

Lists

Method	Signature	Returns

remove_list_item(key, idx)	string, usize → JsValue (Patch[])	Remove item by index
set_list_item(key, idx, json)	string, usize, string → JsValue (Patch[])	Update item fields
get_list_count(key)	string → usize	Get number of items

JSON format: '{"text": "value", "done": false}'

SSR

Method	Signature	Returns
render_to_html()	→ string	Render current document to HTML
markout_to_html(input)	static, string → string	Render Markout directly to HTML

IDE

Method	Signature	Returns
insert_component(line, type, label, key, style)	usize, string×4 → Patch[]	Insert component at line
insert_container(line, tag, config)	usize, string×2 → Patch[]	Insert container (start + end)
update_line_component(line, type, label, key, style)	usize, string×4 → Patch[]	Replace line content
remove_line_at(idx)	usize → Patch[]	Delete a line
move_line(from, to)	usize×2 → Patch[]	Reorder lines
get_line_info(idx)	usize → JsValue (LineInfo)	Get parallel strings + meta
get_line_count()	→ usize	Total line count

LineInfo Object

{
    content: "Hello",
    components: "LLLLL",
    state_keys: "_____",
    styles: "     ",
    is_container_start: false,
    is_container_end: false,
    tag: null,
    config: null
}

Patch Types

All mutation methods return an array of patches:

[
    { type: "Replace", path: [0], node: { ... } },
    { type: "UpdateText", path: [1, 0], text: "new value" },
    { type: "SetAttribute", path: [2], key: "class", value: "mc-primary" },
    { type: "Insert", path: [3], node: { ... } },
    { type: "Remove", path: [4] },
    { type: "RemoveAttribute", path: [5], key: "checked" }
]

Apply with patcher.applyPatches(patches).
