kandi X-RAY | node-ffi-napi Summary

node-ffi-napi is a JavaScript library typically used in Utilities, Wrapper, Nodejs applications. node-ffi-napi has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can install using 'npm i ffi-napi' or download it from GitHub, npm.

[Dependency Status] node-ffi-napi is a Node.js addon for loading and calling dynamic libraries using pure JavaScript. It can be used to create bindings to native libraries without writing any C++ code. It also simplifies the augmentation of node.js with C code as it takes care of handling the translation of types across JavaScript and C, which can add reams of boilerplate code to your otherwise simple C. See the example/factorial for an example of this use case. WARNING: node-ffi-napi assumes you know what you’re doing. You can pretty easily create situations where you will segfault the interpreter and unless you’ve got C debugger skills, you probably won’t know what’s going on. WARNING: The original API of node-ffi is left mostly untouched in the N-API wrapper. However, the API did not have very well-defined properties in the context of garbage collection and multi-threaded execution. It is recommended to avoid any multi-threading usage of this library if possible.

QUESTION

Create struct in C/Rust code for Node-FFI

Asked 2021-Apr-26 at 07:56

I am trying to return a struct from a Rust function to Node.js, the struct is nested, and contains an array so it is sufficiently complicated that I want to do the allocation in Rust and have Node.JS receive a complete object, here's the Rust code in short:

A State is returned that contains a number of Configs, a message (e.g error message, or some warning) and a number of configs.

Containing an array was the tricky/trap part. Arrays in C (ergo FFI) tend to be zero terminated, but there's no guarantee that things work a particular way for arrays of structs.

Here's what we had to do:

In Rust, expose a struct with a length member, and a pointer to a single item.
In Rust, allocate a vector of our things and use into_boxed_slice() to forget it, this gives a pointer to the first one.
Fill the length property on our struct

Everything like in the example we posted first.

In node.js however it's a bit different, the working code was nearly identical to what we had, here's the types:

I got the answer for this case. In posted situation, I used nodeIntegration: true then I implemented the example used const remote = window.require('electron').remote and remote.require features. Then, AddressForArgs(†1) via ref.HexAddress returns electron client based address maybe ( I don't know more internals of the node-ref-napi, node-ffi-napi and electron just now ).

Therefore, I tried change to nodeIntegration: false setting with preload features.
