query: 'body',
func: harmonCheerio((element, req) => {

element.append('<script src="/path/to/polyfill.js"></script>');
}
})
}
]));const harmonCheerio = require('harmon-cheerio');
// ...
app.use(harmon([], [
{
query: 'script#session-placeholder',
func: harmonCheerio(async (element, req) => {
// pretend we need to make a request to get the user's session data
const sessionData = await getSessionData(req.session.id);
element.text(`const SESSION = ${JSON.stringify(sessionData)};`);
