Introduction

@netlify/binary-info is a WebAssembly(WASM) module to extract very specific information from binary files.

It's used by other Netlify projects to detect Go and Rust binaries built for Netlify Functions and its architecture and platform .

Usage

1import { readFile } = require("fs");
2import { detect, Runtime }from "@netlify/binary-info";
3
4const buffer = await readFile(path);
5try {
6  const info = elf.detect(buffer);
7  switch (info.runtime) {
8    case Runtime.Go: console.log("Go binary file"); break;
9    case Runtime.Rust: console.log("Rust binary file"); break;
10    default: console.log("Unknown binary file");
11  }
12} catch (error) {
13  console.log(error);
14}
