Deno Foreign Function Interface.

deno_ffi is a Deno plugin for loading and calling dynamic libraries using pure JavaScript/TypeScript. It can be used to create bindings to native libraries without writing any Rust code.

It also simplifies the augmentation of Deno with Rust/C/C++ code as it takes care of handling the translation of types across JavaScript/TypeScript and C/Rust, which can add reams of boilerplate code to your otherwise simple C/Rust. See the example/ for an example of this use case.

Example

import * as ffi from "https://deno.land/x/ffi/mod.ts";

const libm = ffi.Library('libm', {
  'add': [ 'int', [ 'int', 'int' ] ]
});
libm.add(1, 2); // 3

// You can also access just functions in the current process by passing a null
var current = ffi.Library(null, {
  'btoa': [ 'string', [ 'string' ] ]
});
current.btoa('1234'); // MTIzNA==

    Question about structs and by value calls

    Thank you for maintaining this project. After browsing the internet I found out that im lacking some use-cases when it comes to deno FFI.

    First one is that I do not exactly know to to define an C-Struct Datatype on the deno end. Just given the example struct color { unsigned char r; unsigned char r; unsigned char b; unsigned char a; }

    I thought I should by using 'type' in Typescript. But this seems not to be valid syntax in Deno. Could you please provide me an example?

    If this struct would get providden as pointer or reference, I would know what to do. But I get it as 'by value'. Just replacing it with an u8Array was not working for me. Probably I did it wrong.

    So the second question is how to use this kind of data as argument. void setColor(Color c); Again, using u8Array was not successfull and an 'buffer' seems not to match the signature. Could you please provide an short sample how to make a function call 'by value' in this case?

    Thank you very much
