Trying to build for MSVC x86 due to loading 32bit Dlls on WIndows...

This fails with the NAPI library being the cause. Attached is a log of the build process:

Seems to compain a lot about expecting u32 but finding u64

Hello I have some questions about the new #[napi]:

• how to make a class with a static method that returns an instance (which is not the constructor, of course)
• how to export a const/static?
• ...I have (or probably will have) more, but these are the only ones that come to mind at the moment.

Thanks a lot for your work!

We've had a user reporting unusually high memory usage, growing slowly in their use. I tried to reduce this to the minimal, and I think what I have in this test repo will reveal the leak:

https://github.com/pimeys/napi-bug-repo

I included a massif dump from valgrind in the repo to see it for yourself, but basically we just consume more memory, without collecting at any point.

Here's the original user issue, which is kind of lot to build for testing. But I see similar trend from the user project:

https://github.com/prisma/prisma/issues/7092

I hope the reduced example is enough for you to debug!

Everything is just fine in debug mode, but node.exe exit with status 1 while loading the .node file compiled with --release flag

See https://github.com/napi-rs/package-template/actions/runs/361398266

I am really new to rust and all that universe.

i tried to install napi and so on, but i get:

error[E0004]: non-exhaustive patterns: `napi_bigint` not covered

Thanks :)

Hey @Brooooooklyn, tried to follow this example, but I can't use ThreadsafeFunction.

no method named `create_threadsafe_function` found for reference `&napi::Env` in the current scope
method not found in `&napi::Env`

I have version 5.1 installed, does only 4.x support these methods?

napi-rs 是个很赞的项目，目前我在Electron内用来开发mac及Windows平台的原生node扩展，目前遇到一个（特定系统版本？）崩溃问题。

问题描述：Mac OS X 10.15.3版本系统，Node Addon 崩溃，我尝试运行最简单的 addplus 扩展，依旧是崩溃的。在高版本的macOS系统上，运行正常。

Electron版本：12.2.3 Node版本：14.16.0

下面是崩溃日志，修改了部分敏感数据。

It appears that when a napi-rs 2.0 module is required both on the main thread and in a worker_thread, exported functions can become undefined. I originally saw this issue in blake-hash, and found a reproduction case that I've tested on package-template and @node-rs/xxhash as well.

I also tested the same reproduction case with @node-rs/xxhash v1.0.1 and the issue doesn't reproduce -- it works as expected on that version.

Reproduction case

Using commit d6bb01d from main branch of package-template:

const { Worker, isMainThread } = require('worker_threads')

// When testing, replace with path to a local build of package-template
const template = require('/Users/dguenther/repos/package-template')

if (isMainThread) {
    console.log('outside worker')
    new Worker(__filename)
} else {
    console.log('inside worker')
}

console.log(template)
if (template.plus100) {
    console.log(template.plus100(0))
}

Logs from running the reproduction case:

outside worker
{ plus100: [Function: plus100] }
100
inside worker
{ plus100: undefined }

I was not able to get this example to run with ia32 (worked fine with x64 and I could build it on my mac as well.) https://github.com/napi-rs/napi-rs/blob/main/examples/napi/src/class.rs

Even with a simple class along the lines of this. It builds fine, but even when I just call require('./index.node') it shuts down the program:

use napi::bindgen_prelude::*;

#[napi]
pub struct MyClass(u32);

#[napi]
impl MyClass {
    #[napi(constructor)]
    pub fn new() -> Result<Self> {
        Ok(Self(13))
    }
}

napi = "2.0.0-beta.2"
napi-derive = "2.0.0-beta.1"

napi-build = "1.2"

"@napi-rs/cli": "2.0.0-beta.3"

This code should "just work"

  version: String,

}

#[napi]

  let p: PackageJson = serde_json::from_str(&raw)?;
  Ok(p)
}

Hi! thanks for the amazing framework! I've been using it in two of my currently only public Rust projects, one of which has garnered over 7k downloads a month last year. <3

This issue is a proposal for a feature that i thought would be neat if you can implement it to napi-rs, where you can customize how the node:util module inspects a class object (similar to that of Python's __repr__ or Rust's fmt::Debug trait) with the util.inspect.custom symbol.

I'm getting this error

error: higher-ranked lifetime error
  --> src\server.rs:25:1

   | ^^^^^^^

   = note: could not prove `impl futures_util::Future<Output = std::result::Result<(), napi::Error>>: std::marker::Send`
   = note: this error originates in the attribute macro `napi` (in Nightly builds, run with -Z macro-backtrace for more info)

I'm not really sure how to tackle this to be honest, what I need to look at, or what even causes this.

Added jsFile to the build config for package.json. It allows users to specify where to store the generated javascript bindings file. Currently, the only workaround is to either specify it on the command line (which is fine if you use NPM scripts), but if you want to one-off run napi build --some-flag and forget to add --js path/to/index.js then you'll miss out on it. This feature fixes this problem.

When I run tests that involve napi on Windows with nextest (multi-threaded) I get an error that reports: "GetProcAddress failed". The same tests succeed on Ubuntu & MacOS.

• #1175

this is correctly:

There is no prompt after adding #[napi(constructor)]:

This makes it difficult to edit the impl { }
