windows-installer

Node.js bindings for the Windows Installer API

This package lets you open, query and modify MSI files from Node.js. It provides some abstraction on top of the native Windows Installer API but otherwise just passes through any arguments.

The API is currently synchronous and will throw errors at the Windows Installer API's behalf.

Usage

Install the package

$ npm install --save windows-installer

Query the database

const wi = require('windows-installer');
 
const db = new wi.Database('C:/Installer.msi', wi.MSIDBOPEN_READONLY);
const view = db.openView("SELECT * FROM _Tables");
 
view.execute();
 
let record = null;
 
while ((record = view.fetch())) {
    console.log(record.getString(1));
}

API coverage

MsiDatabaseGetPrimaryKeys	db.getPrimaryKeys(<TableName>)
MsiDatabaseIsTablePersistent	db.isTablePersistent(<TableName>)
MsiDatabaseOpenView	db.openView(<Query>)
MsiOpenDatabase	new Database(<Path>, <PeristMode>)

View functions

View functions requires a View (named view in the examples below). This can be obtained by running openView on a Database instance.

Win32 Function	Node.js function
MsiViewGetColumnInfo	view.getColumnInfo(<InfoType>)
MsiViewClose	view.close()
MsiViewExecute	view.execute()
MsiViewFetch	view.fetch()
MsiViewGetError	view.getError()
MsiViewModify	view.modify(<Mode>, <Record>)
