To install:

import { ExternalProgram } from "external-binary"
import { spawn } from "child_process"
;(async () => {
  const program = new ExternalProgram({
    name: `mongo`,
    sources: [
      {
        arch: "x64",
        platform: "linux",
        downloadUrl: `https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1804-4.2.8.tgz`,
        checksum: "123456",
        checksumAlgorithm: "md5",
        decompress: true, // if the downloaded file needs to be decompressed. the format is retrieved by extension. otherwise assume the file is the executable
        binaryPath: `bin/mongo` // if decompressed, the relative path to the binary starting from the decompressed folder
      }
    ]
  })
  await program.load() // prepare the binary. e.g. download/unzip
  const process = spawn(program.executablePath, ["--port", "27017"])
  process.on("data", data => console.log(data))
  process.on("exit", code => console.log(`exited ${code}`))
  process.kill()
