Or-tools: Is there any plans for Javascript bindings for or-tools?
Just asking, is there any plans for Javascript bindings usable in Node.js for or-tools?

Not really :-(

Are there ways at least we could achieve it?

I implemented a C++ NPM that uses or-tools, but the JavaScript bindings are proprietary (that is, they look nothing like the or-tools API). So I know it is feasible. I think a general-purpose NPM would bring tremendous value.

I have looked at swig.
You can generate node.js bindings.
There are multiple hurdles moving forward:
- convert std::vector<> to javascripts arrays (back and forth)
- protobufs. We are moving to protobuf 3, which supports translation to
json, but making it right will be time consuming.

Hey, a quick follow up here. I tried giving the Swig approach a shot but it turned out to not be a great fit.
I then built some Node.js bindings for the routing model abstractions in or-tools:

It's still in its early stages (e.g. I'm currently working on packaging up pre-built binaries for npm, so all users have to do is npm install) but should already work well for simple use-cases.
