What does the links function output in Remix?

Given this links function in a Remix route, what will be the rendered HTML output in the document head?

export function links() {
  return [{ rel: "stylesheet", href: "/styles/global.css" }];
}

A <style>@import "/styles/global.css";</style>

B <script src="/styles/global.css"></script>

C <link rel="stylesheet" href="/styles/global.css">

D <link href="/styles/global.css" rel="script">

💡 Hint

Think about how stylesheets are linked in HTML head.

The links function returns an array of link descriptors. Remix renders them as tags with the given rel and href attributes. For stylesheets, rel must be "stylesheet".

📝 Syntax

Which links function syntax is correct for adding multiple stylesheets?

Choose the correct links function that returns two stylesheet links in Remix.

A

export function links() {
  return [
    { rel: "stylesheet", href: "/styles/base.css" },
    { rel: "stylesheet", href: "/styles/theme.css" }
  ];
}

B

export function links() {
  return [
    { rel: "stylesheet", href: "/styles/base.css" },
    "/styles/theme.css"
  ];
}

C

export function links() {
  return [
    { rel: "script", href: "/styles/base.css" },
    { rel: "stylesheet", href: "/styles/theme.css" }
  ];
}

D

export function links() {
  return {
    rel: "stylesheet",
    href: ["/styles/base.css", "/styles/theme.css"]
  };
}

💡 Hint

The links function must return an array of objects with rel and href keys.

The links function must return an array of objects, each with rel and href properties. Option A correctly returns two stylesheet link objects. Option A returns an object, not an array. Option A has a wrong rel value for the first item. Option A mixes object and string types in the array.

Why does this stylesheet not load in Remix?

This links function is supposed to add a stylesheet but it does not load. What is the cause?

export function links() {
  return [{ rel: "style", href: "/styles/app.css" }];
}

A The rel attribute should be "stylesheet", not "style".

B The href path must start with "./" to load correctly.

C The links function must return a string, not an array.

D The links function must be async to load stylesheets.

💡 Hint

Check the rel attribute spelling for stylesheets.

The rel attribute for stylesheets must be exactly "stylesheet". Using "style" is invalid and the browser ignores the link tag, so the stylesheet does not load.

What is the effect of returning an empty array from links function?

If a Remix route's links function returns an empty array, what will happen to stylesheets in that route?

Remix

export function links() {
  return [];
}

A All stylesheets from parent routes will be removed.

B No additional stylesheet links will be added to the HTML head for that route.

C The route will throw a runtime error due to missing stylesheets.

D The default Remix stylesheet will be added automatically.

💡 Hint

Think about what an empty array means for returned links.

Returning an empty array means no new link tags are added by this route. Stylesheets from parent routes remain unaffected. Remix does not throw errors or add defaults automatically.

How does Remix combine links from nested routes?

In Remix, when multiple nested routes each export a links function returning stylesheet links, how does Remix handle these links in the final HTML output?

A Remix only renders the links from the deepest child route, ignoring parents.

B Remix requires manual import of parent links in child routes to combine them.

C Remix concatenates links but removes duplicates by href automatically.

D Remix merges all links arrays from parent to child routes and renders all link tags in the HTML head.

💡 Hint

Consider how nested routes build the page together.

Remix automatically merges the links arrays from all matched routes in the nesting hierarchy. It renders all link tags from parent and child routes in the HTML head, so stylesheets from all levels apply.
