Are template literals safe for dynamic routes in Node.js?

Hey everyone, I'm curious about the safety of using template literals for dynamic routes in Node.js, especially with Express. For instance, I've got this route set up:

app.get("/posts/:postID", (req, res) => {
// retrieve post info from database
});

Then on the front end, I have this function:

async function getPostInfo() {
const response = await fetch(`/posts/${postID}`);
const post = await response.json();
return post;
}

If I ensure that I use parameterization for my Postgres queries, is this a secure way to handle requests? It seems like it should work, but I'm still pretty new to Node.js and I want to make sure I understand any potential vulnerabilities, like XSS. Appreciate any insights you can share!
