Enhancing Meteor.js with Node-API Integration for Seamless Foreign Function Support

I have an idea that could significantly enhance Meteor’s capabilities, especially for those of us who push our applications to the limits of performance and scalability. Let’s explore integrating Node-API support directly into the Meteor project structure and scaffolding to automatically build and manage foreign functions within our projects.

The Concept

Meteor.js has long been celebrated as one of the best frameworks for rapidly prototyping applications. Its seamless integration between frontend and backend, along with a robust ecosystem, makes it a favorite among developers. However, as applications grow and computational demands increase, some developers hesitate to use Meteor, citing performance and scalability concerns.

To address this, I propose integrating Node-API into Meteor’s project structure. This integration would allow developers to incorporate foreign functions—written in languages like C/C++, Rust, or others—directly within their Meteor projects. The idea is to have Meteor’s package bundler automatically traverse the project tree, identify foreign function directories, determine their respective languages, and create the necessary build commands to compile these functions for server-side use.

Proposed Project Structure

Here’s an example of how your project could be organized to support this integration:

/imports
  /api
    /Posts
      index.js          // Contains Collection Schema and Hooks
      methods.js        // Contains RPC Methods for Collection
      publications.js    // Contains Publications for Collection
      /foreign_functions // Folder for foreign functions (C/C++, Rust, etc.)
        /rust_fn
          src/
            lib.rs
          Cargo.toml
        /cpp_fn
          src/
            func.cpp
          Makefile

In this structure:

  • /foreign_functions: A dedicated directory within each collection (e.g., Posts) to house foreign functions.
  • Subdirectories: Each foreign function can reside in its own subdirectory, containing all necessary source files and build configurations.

How It Would Work

  1. Automatic Detection: Meteor’s package bundler scans the /foreign_functions directories within your project.
  2. Language Identification: It identifies the programming language based on the folder structure or specific configuration files (e.g., Cargo.toml for Rust, Makefile for C++).
  3. Build Process Integration: Meteor generates appropriate build commands to compile these foreign functions during the build process.
  4. Seamless Integration: Compiled binaries or shared libraries are then made available for import into your server-side logic, allowing you to leverage the performance benefits of these languages without leaving the Meteor ecosystem.

Benefits

  • Performance Optimization: Offload computationally intensive tasks to more performant languages, enhancing overall application efficiency.
  • Flexibility: Utilize the best tool for each job without being constrained to JavaScript/Node.js for all backend logic.
  • Ease of Use: Maintain a cohesive project structure where all components, including foreign functions, are managed within Meteor’s scaffolding.
  • Scalability: Mitigate performance bottlenecks that arise as applications grow, ensuring Meteor remains a viable choice for large-scale projects.
  • Community Empowerment: Enable the community to maximize the potential of Meteor by integrating diverse technologies seamlessly.

Why Meteor?

In my experience, Meteor excels at rapid development and prototyping. However, as projects scale, the need for optimized performance becomes critical. Integrating Node-API and supporting foreign functions addresses a common concern, potentially making Meteor an even more attractive option for developers who require both speed in development and performance in execution.

Call to Action

I believe this integration could be a game-changer for the Meteor ecosystem, bridging the gap between ease of development and high-performance requirements. I’d love to hear your thoughts, feedback, and any experiences you’ve had with integrating foreign functions into Meteor projects.

It’s fairly easy to support WASM in Meteor, and I covered it on my blog some time ago: On WebAssembly in Meteor. You could extend it also to do the build step (e.g., wasm-pack for Rust), and have it all happen automatically.

The downside of not having this pre-build step is that a lot of those WASM-generating tools also generate TypeScript definitions, and if Meteor would build it, there’d be no types before the app is run.


As for the N-API instead of WASM, it works exactly the same – a build step is needed, and you can import it in Meteor. (It’s even slightly easier, as there’s no WebAssembly.Module and WebAssembly.Instance to juggle around.) napi-rs also generates TypeScript definitions, so the experience would be very similar (except for cross-compilation, as N-API is platform-dependent).

I don’t see anything that would prevent this from being implemented as a build plugin if someone wants to experiment with it.

This reminds me of what bun is doing:

Found this in my notifications. Please be sure to keep us updated. This is pretty interesting, but currently outside of the scope of my expertize and current needs. Still academically this looks pretty good.

As for the structure I there was already move away from reserved folder names, so I think we can make foreign_functions or something like that reserved by default and we should have in package.json field to specify the folders where these files are located, like we have with the start point for client and server.
