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.

$ npm install --save windows-installer

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));
}

Database functions requires a Database (named db in the examples below). This can be obtained by running new Database(<Path>, <PersistMode>).

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

Record functions requires a Record (named rec in the examples below). This can be obtained by running fetch on a View instance or by running new Record(<NumFields>).
