Curve not enabled by default

[muscleman]

following some examples of implementing curve on a pub/sub i get cannot set public, secret or server public keys

setting socket.curveserver = true throws exceptions too.

• OS: [Ubuntu 22.04]
• ZeroMQ.js version: [6.0.0-beta.20]

Curve is not included in the prebuilt binaries anymore following the upstream approach. You should build the binaries from the source if that is desired.
Also see,
#638 (comment)

so adding
`
#.npmrc

build_from_source=true
zmq_draft=true
`

and setting
#build.ts -DWITH_LIBSODIUM=ON

is enough to get curve?

[muscleman]

nope, still want work

[muscleman]

would be super helpful if someone could do a little documentation on how to turn on curve

@aminya is it planned that curve will be reintegrated into the prebuilt binaries?

[aminya]

Curve needs to be added to the project prebuilds so it works out of the box.

I have migrated the build to CMake/vcpkg. Now you can enable the Curve support through npmrc by building from the source.

Hi, @aminya

Tried installing zeromq with the following .npmrc file:

build_from_source=true
zmq_curve="true"
zmq_sodium="true"

But when I run this snippet [on a ubuntu machine]:

import * as zmq from "zeromq";

try {
  zmq.curveKeyPair();
} catch (err) {
  console.log(err);
}

I get Error: Operation not supported.
Did I miss a step ?

It should have worked, if it doesn't that's an issue we need to look into. Did it rebuild Zeromq from the source once you did this?

I think so. At least the first time I attempted to do npm install zeromq it failed, because I didn't have cmake installed.
Once I installed all the required dependencies, the installation succeeded.

Ok. Thanks for the report. I'll soon try to add it to the CI and reproduce it.
