"Why isn't fetch in nodejs working like it does in the browser?"

hey guys, so i’m trying to use fetch in nodejs for a simple API call, but it’s acting weird??

in the browser, it works fine, but in node, i keep getting "fetch is not defined" errors. what gives?

i thought node had fetch now? or do i still need to install something?

also, if there’s a better way to do this natively, lmk. not sure if i should use axios or stick with fetch in nodejs.

thanks for any help!

"Fetch in nodejs keeps giving me errors—what am i missing?"

ugh, why is fetch in nodejs so finicky??

works in chrome, breaks in node. do i need a polyfill or something?

help a dev out pls 😅

Ah, the classic fetch in nodejs struggle! Node didn’t include fetch by default until recently, so you’ll need to either:

- Use Node 18+ (it’s built-in now!)
- Install node-fetch or undici if you’re on an older version.

Also, check if you’re mixing CommonJS/modules—that can break it. Axios is solid too, but fetch in nodejs is totally viable once you sort the setup.

yep, fetch in nodejs is kinda new as a native thing. if you’re on node <18, you gotta install node-fetch (or undici, which is what node’s fetch actually uses under the hood).

pro tip: if you’re using ESM, make sure to import it right—`import fetch from 'node-fetch'` vs require() can trip you up.

axios is more stable for older projects, but fetch is fine if you’re up-to-date!

lol welcome to the "why doesn’t fetch in nodejs work" club. 😅

short answer: node only added it natively in v18. before that, you needed node-fetch. even now, some folks prefer undici for perf.

if you’re stuck, just `npm install node-fetch` and carry on. or yeah, axios is the OG for a reason—fewer surprises.

Fetch in nodejs is weird because it wasn’t a thing until Node 18. Before that, everyone used node-fetch or axios.

If you’re getting "fetch is not defined," you’re probably on an older Node version. Check with `node -v`.

Quick fix: `npm install node-fetch@2` (v3+ is ESM-only, which might break your setup). Or upgrade Node!

wait, so if i’m on Node 16, i *have* to install node-fetch? that’s annoying.

just tried `npm install node-fetch@2` and it worked! but now i’m wondering if i should upgrade to Node 18 instead.

also, why’s everyone hyping undici? is it faster or something?

thanks for the help, y’all! 🙏

ugh, fetch in nodejs is such a mess. it’s native in Node 18+, but if you’re not there yet, you’ll need node-fetch.

fun fact: node’s built-in fetch uses undici, so you could just install that directly (`npm install undici`) and use its fetch.

axios is more bulletproof tho, esp if you need interceptors or older Node support.

Fetch in nodejs is a recent addition, so if you’re not on Node 18 or later, it won’t work out of the box.

Either upgrade Node or install node-fetch. If you go the install route, watch out—node-fetch v3+ requires ESM, so stick with v2 if you’re using CommonJS.

Axios is a safe bet if you don’t wanna deal with this mess.

ohhhh this is a rite of passage for node devs. fetch in nodejs wasn’t a thing until Node 18, so you’ve got options:

1. Upgrade to Node 18+ (easiest if you can).
2. `npm install node-fetch` (but v3+ needs ESM, so maybe v2).
3. Use undici (`npm install undici`)—it’s the engine behind node’s fetch.

axios is chill too, but fetch is legit once you sort the setup.
