Example

const is64bit = require('is64bit');

is64bit("hello_world.exe").then((is64) => { 
  console.log(`64-bit: ${is64}`) //True or false
}).catch((err) => { console.error(err) });

//async/await
(async ()=>{
  try{
    let is64 = await is64bit("hello_world.exe");
  }catch(err){
    console.error(err);
  }
})();

Check binary from another platform

//Linux binary with Node running on Windows
const is64bit = require('is64bit');

is64bit("hello_world","linux") //same values as os.platform()
.then((is64) => { 
  console.log(`64-bit: ${is64}`) //True or false
}).catch((err) => { console.error(err) });
