Bun's Roadmap

[Jarred-Sumner]

Bun's roadmap

2024 Q3

bun install

Essentially, feature complete.

• bun outdated
• Implement bun pack #487
• bun publish
• Text-based lockfile format
• bun update --interactive
• Fixes for frequently-reported issues for things like private git URLs and some edgecases with hoisting

Runtime

Node.js compatibility

• TextEncoderStream & TextDecoderStream
• V8 C++ API (in-progress)
• Implement node:cluster
• Implement node:http2 server to unblock grpc2
• Rewrite node:zlib (in-progress) to address performance issues in some common packages
• Rewrite node:crypto #13681
• Fix various bugs in node:http, avoid wrapping Bun.serve() and fetch() and use a more direct implementation
• Add much more comprehensive test coverage for napi
• Get at least 25% of Node's test suite running on every commit (as of last update: 15% currently). This number will go up in future quarters.

Reliability

• Delete almost all code that manually reads JSValue. Replace with an IDL bindings generator for JavaScriptCore objects/classes that supports C++ & Zig output, and importantly: function arguments, return values, and exceptions. It should make the lifetime of these values brainless for us to reason about.
• Address TLS-related issues that have cropped up
• Continue to allocate significant time to fixing bugs and improve test coverage as they crop up

Bundler

• Fix many common bugs people run into related to source maps or incorrect output
• Begin implementing a new, higher-level iteration of Bun's bundler designed for server-driven JavaScript (in-progress)
• CSS parser (in-progress)
• IIFE output format + --global-name

bun test

• Reporter API or socket API

Organizational

• Hire a contractor to help us with CI
• Hire a technical writer to help with docs
• Hire an engineering-focused role for maintaining the TypeScript types & frontend for docs + help with integrations with third-party packages
• Hire more systems engineers

this seems like a lot of work... wow

[space7panda]

Can't wait for full npm-like config support. We are using our own npm registry, and the current build time is 40-60 minutes. If it will be at least 10 minutes this will be a game-changer!

[officialrajdeepsingh]

I am waiting for the stable version of the bun. What change bun in the javascript world.

[tipiirai]

Also waiting for the stable version. So exciting! I bet it's going to take a lot of time though. The scope of this project is much larger than what Node attempts to solve.

[matepaiva]

can someone confirm that right now I can't use the package mysql2? It throws me an error because it depends on TLS package and on NET package, and I think they were not implemented yet in Bun, but I am not sure.

[Kapsonfire-DE]

still missing websocket server support

[GCSBOSS]

Can a tinitiny docker image be placed somewhere in there? 👀

[MystPi]

Can't wait for Windows support... I'll be anxiously awaiting it until it's out. 😅

Dito

[sodeprecated]

Are you planning to support http2?

[moderation]

Are you planning to support http2?

HTTP/3 is on #159 so I would say HTTP/2 will likely be added before that

[sodeprecated]

HTTP/3 is on #159 so I would say HTTP/2 will likely be added before that

I would say that http3 on roadmap is more about quic protocol and there is no straight inheritance between http3 and http2, so maybe support of http2 needs to be marked explicitly.

[frodoe7]

Motivated to see a stable version ASAP

[LaurelineP]

Promising !
Any roadmap on a progressive translation ?

[Parvat-R]

When is the support for windows coming? Cant wait for it.

[jacoscaz]

I would say that http3 on roadmap is more about quic protocol and there is no straight inheritance between http3 and http2, so maybe support of http2 needs to be marked explicitly.

Another vote for HTTP/2 as it's a prerequisite to gRPC support.

[dyaskur]

Any plans to create a desktop app like electron?

[xhyrom]

When is the support for windows coming? Cant wait for it.

#43 you can use WSL for now

[hedaukartik]

When can we have CSS/SCSS parser feature?

[aralroca]

When can we have CSS/SCSS parser feature?

Looking forward to the CSS parser too

Bump... really need this, game changer

[d4mr]

based on @Jarred-Sumner's answer here, where does Telemetry fit into the current roadmap?

[Confucian-e]

Please Fix this Bug ASAP
#5856

[yorunoken]

Please Fix this Bug ASAP #5856

Jarred has already said the bug will be fixed a little bit after v1.1 is finished. The development team is currently working on the Windows release.

[lsnow99]

Would love to help support work on #2704 as part of the Developer Experience roadmap

[truekamleshsingh]

Thanks, #Bun for being a fast and easy-to-use JavaScript runtime! I appreciate your speed and compatibility with existing Node.js projects.

[olawalejuwonm]

How do I use bun with nest Js?

+1 for TextDecoderStream
AuthJS relies on this and will be out soon (successor to NextAuth)

[001123]

Is NextJS fully supported?
I test on my project it work well

[cotwitch]

@001123 Do you use "Pages Router" or "App Router" ?

I'm just test on "Pages router"

[kaitlynia]

Any plans to support WebRTC data channels in the API? Very happy with the performance of the WebSockets API and would love to see more of these modern protocols (+1 for HTTP/3) getting some attention. Currently, there are Node.js bindings for libdatachannel but at the time of writing, no runtime has implemented data channels natively.

[hedaukartik]

When can we get CommonJS output format support for the build?
https://bun.sh/docs/bundler#format cjs

[huseeiin]

"Support blob: imports & URLs (URL.createObjectURL, URL.revokeObjectURL)" is done right? it should be checked

[guest271314]

@huseeiin

"Support blob: imports & URLs (URL.createObjectURL, URL.revokeObjectURL)" is done right? it should be checked

What are you observing is an issue with the implementation?

It looks like URL. is defined on a global url`, which is odd to me to have a common variable name defined globally. Otherwise appears to work.

[powerpaul17]

@guest271314 , I think @huseeiin meant it can be checked in the list since it seems to be implemented 😉

[Edberaga]

Are there any pre-requities to use and learn Bun?

[millette]

@Edberaga

[eknowles]

@Jarred-Sumner i think many more of these items can now be ticked off 🙌

[jhaemin]

I'm still waiting for IIFE output format. It's the only reason I can't use Bun as a bundler.

[Jarred-Sumner]

Updated.
