![A piece of lua code. It contains a function called `extract_preloader`. It uses a html parser to extract every script with a type of `application/json`, then iterates over those to find ones with a given structure.
The full contents of the unfinished function is pasted below:
local function extract_preloader(html_page, query_name)
local html_root = html.parse(html_page)
local json_elements = html_root:select("[type='application/json']")
for element in ipairs(json_elements) do
local json_content = element:getcontent()
local decode_status, decoded_content = helpers.safe_json.decode(json_content)
if not decode_status then
break
end
if helpers.check_nested_field(decoded_content, "require", 1, 4) then
local bboxes = decoded_content.require[1][4]
for _, bbox in ipairs(bboxes) do
bbox = bbox.__bbox
if bbox.require then
for _, requirement in ipairs(bb](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:22l5hixwr3ffouf6eabgpvo2/bafkreiekfgfqqj6dih7wa3cdnbctn25jmagmgertkrdyyiwnqf3c357w7u)
