The module for working with COM objects

Usage sample:

const wdExportFormatPDF = 17 // PDF
const COM = require('@unitybase/com-bridge')
const path = require('path')
const fullTestFilePath = path.join(__dirname, 'test-doc.docx')
const fullPDFFilePath = path.join(__dirname, 'test-doc.pdf')

const fs = require('fs')

if (fs.existsSync(fullPDFFilePath)) fs.unlinkSync(fullPDFFilePath)

let word = COM.createCOMObject('Word.Application')
word.DisplayAlerts = 0
word.CheckLanguage = false
word.Options.CheckSpellingAsYouType = false

let doc = word.Documents.Open(fullTestFilePath)

doc.ExportAsFixedFormat({
  ExportFormat: wdExportFormatPDF,
  OutputFileName: fullPDFFilePath
})
doc.close({SaveChanges: false})
doc = null
word.Quit()
word = null

Members

createCOMObject static

Create JavaScript wrapper around a COM/OLE object. COM must implement IDispatch interface.

Returning object has the same properties and methods as in original COM object.

Names of methods and properties are case-insensitive. If COM object has get-properties with parameters they implemented as a functions in JS-object.

Method can take unnamed parameters(normal usage), you must use the correct order of the parameters, or named parameters(in this case functioin take a {Object} with keys = parameter name and values is a parameter values)
