A patch to run prior to building a typescript project that uses the azure-arm-website node module.

patch-azure-arm-website.js

'use strict';

const fs = require('fs');
const path = require('path');

function patchFile() {
    //get the path to the file to be patched. This is for differnet OS's.
    const basePath = path.join(__dirname, 
        'node_modules', 'azure-arm-website', 'lib', 'models');

    //the actual file we are modifying.
    const modulefile = path.join(basePath, 'index.d.ts');

    // read the file. If error, than module probably doesn't exist.
    fs.readFile(modulefile, (error, contents) => {
        if(error) {
            console.log("Error reading module. Skipping...");
            return;
        }

        // file exists, so check if it has been patched already or not.
        if(contents.indexOf('import { BaseResource }') > -1){
            console.log("Module already patched. Skipping...");

        let buffer = new Buffer("import { BaseResource } from 'ms-rest-azure';\n");

        // append the patch to the original file. 
        let patched = Buffer.concat([buffer, contents]);

        //write the patch file to the original file name.
        fs.writeFile(modulefile, patched, function(err) {

// run the patch operation.
