unoconv
  .convert("./mydoc.doc")
  .then(fileBuffer => {
    // Converted file buffer
    return Promise.resolve(fileBuffer);
  })
  .catch(e => {
    throw e;
  });

Convert document first page to PDF and save to a file

const unoconv = require("unoconv-promise");

unoconv
  .run({
    file: "./mydoc.doc",
    output: "./temp.pdf",
    export: "PageRange=1-1"
  })
  .then(filePath => {
    console.log(filePath);
  })
  .catch(e => {
    throw e;
  });

Show supported formats

const unoconv = require("unoconv-promise");

unoconv
  .formats()
  .then(formats => {
    // formats will be an array contains supports formats
    formats.forEach(format => {
      console.log(format);
    });
