Or could the bundled Undici use the native one? @nodejs/undici |
The architecture and integration of the two is radically different. When switching to the wasm one we actually got an improvement in performance. I think it might be possible to reach a stage where this is possible, but it's probably far from now given we are focusing on fetch. However, things change if people would like to work on this. |
@mcollina This is a problem for us as distro package maintainers as well. Packaging precompiled code is a no-no for us. Is there a way this could be compiled from source during build? How complicated would it be to use non-wasm version given we are okay with worse performance? Or would it be plausible to have an option to have node without undici? IIRC it's used only for fetch which is experimental for now. |
@kasicka you should have a look at how debian is dealing with it. |
@nodejs/tsc we have a decision to make here. One of the reasons we stopped using the native http_parser was due to the use of The second question is who is willing to do the work. Are there any volunteers? |
I have been thinking about how we might move towards a standardized approach for integrating WASM which would address some of the concerns on the distro side. Some aspects of that would include:
@kapouer when you say the nodejs package embeds the result, is it replacing what is in the Node.js upstream by default or some other process? |
FWIW building the wasm needed by undici is completely automated (otherwise is very hard to do it by hand). |
@mhdawson currently the nodejs debian package replaces deps/undici/undici.js during build by the one built by the node-undici debian package using a slightly patched version of undici's build/wasm.js. |
@kapouer thanks for the details. |
I'm thinking that as there are more instances like this, it may become more of an overhead. I assume having a configure time option would make it a bit easier. Thinking out loud a standard approach might be something like:
If the same approach was used in undichi (or at least the same configuration option name) for example, then the option could be simply passed on and the same external file could be used by Node.js core and undichi (although we would still have 2 copies) I'm thinking of this kind of the along the same lines as how we have configure time options to allow components like openssl, cares, etc. to either be bundled in to the node.js binary or linked against as a shared library. We might even be able to use the same approach as for shared libraries by getting the WASM/generated JavaScript from a symbol that is either present in the binary itself or within a shared library but that does seem a bit like putting a square peg in a round hole. |
Why is it necessary to use external versions? Could Debian’s patch be integrated into Uncici’s version somehow? We include a wasm binary for the https://github.com/nodejs/cjs-module-lexer dependency that’s also bundled in Node. I thought that this binary was good to run anywhere without needing recompilation. It feels like this is the model we should be shooting for, that Node’s binaries/scripts can run anywhere, rather than allowing more ways to run custom versions. |
@GeoffreyBooth there two use cases (that ideally are selected by ./configure flags, or worse, by local patches):
Whatever the module is (cjs-module-lexer, undici, acorn, openssl, c-ares, uv, etc...) if it needs to be compiled to be used, In any case, open-source distributions need to recompile each part at some point, during Node build, or during the externalized dependency build. |
That is commendable, as long as you trust the person making the binaries. In Fedora (and derivatives), there is a strict policy of not shipping pre-built anything. One of the reasons why we do this is that there is no guarantee that the compiled binary corresponds to the source in git, and does not include i.e. added crypto-miner or other kind of supply chain attack. Rather that take that risk, we want to rebuild everything from source that we can review, using tools we also built ourselves (so no externally prepared SDKs or similar shortcuts either). That's at least the theory; in practice, corners are sometimes cut and exceptions granted, but we would very much have as little of these as possible. |
I second @khardix : it's "open-source distribution" as in: everything is built from open source code. |
@kapouer, @khardix, @kasicka as consumers of what I've proposed in #44000 (comment) what are your thoughts? |
Perfect ! |

What is the problem this feature will solve?
Versions of Node using Undici (16, 18) are actually using two different copies of llhttp
What is the feature you are proposing to solve the problem?
Would it make sense to use llhttp wasm that is bundled in Undici, instead of recompiling it ?
What alternatives have you considered?
n/a it's a refactoring.
