In the next version of Bun Bun gets a native REPL

This new REPL also doesn't download anything, so it starts up 14x faster

Claude wrote all the code and tests for this

I still think just typing "bun" should start the repl

but where is the next version? 🤔 Fine, I guess you didn't specify that on 'which' Friday

Have wanted this for a long time. Great.

what else you'll include into bun giving it a "World Record" as a bloated runtime?

Please tell me this has top level await and lets me re-import imports (to account for filesystem changes) 🙏

Yes and no but you can add a ?v=1

Docs suggest both of these print 'undefined' but they don't.

Oh yeah RLM definitly making it into Claude code

RLM!

i wonder what this is for @a1zhang

NOW we're talking

banger

ETA?

it'd be cool of the repl was also exposed programmatically!

Oh that’s cool. A native REPL just makes a runtime feel more real somehow. Feels like Bun is slowly filling in all the gaps. Wonder what this unlocks next.

That is cool.

Finally, REPL works in Windows🥲

What are you using for syntax highlighting? Won’t that bloat the binary?

Does it bring tab completion like all the others?

OMG! Finally!

Can we setup python or any package inside it beforehand?

Powerof AI

would it supports external editor like vim?

great would be helpful for me agents

how the heck are you doing syntax highlighting lol

Finally!!!

Tried to build one myself last year. Learned the hard way.

Nice! Any auto-complete?

lol was trying to get the codex cli kernel for js_repl working with bun instead of node two weeks back ty

This is the kind of polish that separates tools people tolerate from tools people love To be fair most devs never notice until they use something better

How many people know the full form of REPL?

Yes thank you (finally)! This is great, dual wielding Bun and Deno in a Bun project (using Deno just for its excellent repl) worked but was of course kind of a mess

fast adding features to Bun lately, AI helps?

this is cooool 🔥🔥

🐐
