Edge runtime vs Node.js runtime in NextJS - Quick Revision & Key Differences

Recall & Review

beginner

What is the Edge runtime in Next.js?

The Edge runtime runs code closer to users on global servers, making responses faster by reducing delay.

intermediate

How does Node.js runtime differ from Edge runtime in Next.js?

Node.js runtime runs on a central server and supports full Node.js APIs, while Edge runtime runs on lightweight servers with limited APIs for speed.

intermediate

Name one limitation of Edge runtime compared to Node.js runtime.

Edge runtime does not support all Node.js APIs like file system access, limiting some server-side features.

beginner

Why would you choose Edge runtime over Node.js runtime?

To deliver faster responses globally by running code near users, improving performance and reducing latency.

beginner

Can you use Node.js libraries that require file system access in Edge runtime?

No, Edge runtime does not support file system APIs, so such Node.js libraries won't work there.

Where does Edge runtime execute your Next.js code?

A Only on your local machine

B Inside the browser

C On a central server far from users

D On global servers close to users

Edge runtime runs code on servers distributed globally to be near users, reducing delay.

Which runtime supports full Node.js APIs in Next.js?

A Edge runtime

B Both Edge and Node.js runtimes

C Node.js runtime

D Neither runtime

Node.js runtime supports full Node.js APIs, while Edge runtime has limited API support.

What is a main benefit of using Edge runtime?

A Access to file system APIs

B Faster global response times

C Supports all Node.js libraries

D Runs only on your local computer

Edge runtime improves speed by running code near users worldwide.

Which runtime would you choose for heavy server-side logic needing file access?

A Node.js runtime

B Static site generation

C Browser runtime

D Edge runtime

Node.js runtime supports file system access needed for heavy server-side logic.

Can Edge runtime run code that requires Node.js file system modules?

A No, not supported

B Yes, fully supported

C Only on certain servers

D Only in development mode

Edge runtime does not support Node.js file system modules.

Explain the key differences between Edge runtime and Node.js runtime in Next.js.

Think about where code runs and what APIs are available.

When would you prefer to use Node.js runtime instead of Edge runtime in a Next.js app?

Consider features that Edge runtime cannot support.
