google.script.run and jQuery.Deferred

google.script.run doesn’t return values. So I tried this using jQuery.Deferred.

GAS : Code.gs

function doGet() {
  return HtmlService.createHtmlOutputFromFile('index')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
}

function getValues(e) {
  return e + "hoge";
}

HTML : index.html

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.js"></script>
<body>
  <input type="button" id="button" value="ok">
  <div id="result"></div>

  <script>
    $(() => {
      $("#button").click(() => {
        var str = "fuga";
        googleScriptRun(str).then((res) => {
          $('#result').text(res);
        });
      });
    });

    function googleScriptRun(str) {
      var d = new $.Deferred();
      google.script.run.withSuccessHandler((res) => {d.resolve(res)}).getValues(str);
      return d.promise();
    }
  </script>
</body>

Result :

fugahoge

Above sample can be also written as follows.

Copying and Overwriting GAS Project

Gists

Pattern 1

This is a sample script for copying GAS project to a container-bound script of Google Docs (Spreadsheet, Document and Form (and Slides)). The project is created as a new project.

In order to use this sample, please do the following installation flow.

If you use this sample script, at first, please test using a new project and new Google Docs. By this, please understand the work of this script.

Batching Requests for Google Apps Script

Gists

There is the bathing requests in the Google APIs. The bathing requests can use the several API calls as a single HTTP request. By using this, for example, users can modify filenames of a lot of files on Google Drive. But there are limitations for the number of API calls which can process in one batch request. For example, Drive API can be used the maximum of 100 calls in one batch request.

Zaif API for Google Apps Script

Gists

This sample script is for using Zaif API by Google Apps Script.

The following go script is a sample at Zaif API.

package main

import (
    "fmt"
    "time"
    "strconv"
    "crypto/hmac"
    "crypto/sha512"
    "io/ioutil"
    "net/http"
    "encoding/hex"
    "net/url"
    "strings"
)

var key = "<your_key>"
var secret = "<your_secret>"

func main() {

    uri := "https://api.zaif.jp/tapi"
    values := url.Values{}
    values.Add("method", "get_info")
    values.Add("nonce", strconv.FormatInt(time.Now().Unix(), 10))

    encodedParams := values.Encode()
    req, _ := http.NewRequest("POST", uri, strings.NewReader(encodedParams))

    hash := hmac.New(sha512.New, []byte(secret))
    hash.Write([]byte(encodedParams))
    signature := hex.EncodeToString(hash.Sum(nil))

    req.Header.Add("Key", key)
    req.Header.Add("Sign", signature)
    client := new(http.Client)
    resp, _ := client.Do(req)
    defer resp.Body.Close()

    byteArray, _ := ioutil.ReadAll(resp.Body)
    fmt.Println(string(byteArray))
}

When this is converted to GAS, the script is as follows.

Bittrex API for Google Apps Script

Gists

This sample script is for using Bittrex API by Google Apps Script.

The following PHP script is a sample at bittrex.com.

$apikey='xxx';
$apisecret='xxx';
$nonce=time();
$uri='https://bittrex.com/api/v1.1/market/getopenorders?apikey='.$apikey.'&nonce='.$nonce;
$sign=hash_hmac('sha512',$uri,$apisecret);
$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);

When this is converted to GAS, the script is as follows.

function main() {
  var apikey = '#####'; // Please input your key.
  var apisecret = '#####'; // Please input your secret.

  var nonce = Number(new Date().getTime() / 1000).toFixed(0);
  var uri = 'https://bittrex.com/api/v1.1/market/getopenorders?apikey=' + apikey + '&nonce=' + nonce;
  var sign = Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_512, uri, apisecret);
  sign = sign.map(function(e) {return ("0" + (e < 0 ? e + 256 : e).toString(16)).slice(-2);}).join("");
  var params = {
    method: "get",
    headers: {Apisign: sign}
  }
  var res = UrlFetchApp.fetch(uri, params);
  Logger.log(res.getContentText())
}

Binance API for Google Apps Script

Gists

This sample script is for using Binance API by Google Apps Script. This script encryptes “signature” like samples. In this script, “Example 1: As a query string” is used, and it retrieves “All orders (SIGNED)” by “GET”.

function main() {
    var key = '#####'; // Please input your key.
    var secret = '#####'; // Please input your secret.
    var api = "/api/v3/allOrders"; // Please input API Endpoint you want.
    var timestamp = Number(new Date().getTime()).toFixed(0);
    var string = "symbol=LTCBTC&timestamp=" + timestamp; // Please input query parameters for the inputterd API.

    var baseUrl = "https://api.binance.com";
    var signature = Utilities.computeHmacSha256Signature(string, secret);
    signature = signature.map(function(e) {
        var v = (e < 0 ? e + 256 : e).toString(16);
        return v.length == 1 ? "0" + v : v;
    }).join("");
    var query = "?" + string + "&signature=" + signature;
    var params = {
        'method': 'get',
        'headers': {'X-MBX-APIKEY': key},
        'muteHttpExceptions': true
    };
    var data = UrlFetchApp.fetch(baseUrl + api + query, params);
    Logger.log(data.getContentText())
}

CLI Tool - goodls

Overview

This is a CLI tool to download shared files from Google Drive.

Description

We have already known that the shared files on Google Drive can be downloaded without the authorization. But when the size of file becomes large (about 40MB), it requires a little ingenuity to download the file. It requires to access 2 times to Google Drive. At 1st access, it retrieves a cookie and a code for downloading. At 2nd access, the file is downloaded using the cookie and code. I created this process as a CLI tool. This tool has the following features.

Google OAuth Verification & Application Privacy Policy

Registered Application Name: Workspace & Gemini AI Orchestration Engine

Application Purpose & Core Functionality:

This web page serves as the official homepage and privacy compliance interface for the application "Workspace & Gemini AI Orchestration Engine". This specialized developer utility is designed to research, benchmark, and optimize advanced integrations between Google Workspace services, the Google Apps Script API, and Gemini AI models (via Google Vertex AI / Gemini API endpoints).

The application facilitates automated multi-agent scaffolding, programmatic script deployment, project resource management, and structural analysis of Google Apps Script projects. It allows developers and autonomous AI agents (operating via Model Context Protocol / MCP) to securely evaluate execution performance, implement high-performance batch requests, and test agent-to-agent (A2A) workflows within a controlled and structured environment.

Google User Data Policy Compliance Statements:

1. Data Access & Specific Usage

Our application explicitly requests access to specific Google user accounts through OAuth scopes required strictly for interacting with the Google Apps Script API and Google Workspace endpoints. This access is utilized solely to execute user-initiated or agent-orchestrated programmatic operations—such as creating, modifying, deploying, or benchmarking script projects and executing automated workflows. No background automated extraction occurs without explicit session initiation.

2. Data Storage & Zero-Retention Policy

Adhering to a strict Zero-Retention Model, this application does not store, log, or persist any personal data, OAuth tokens, script source codes, or Google account configurations on any external server, database, or persistent storage medium. All data processing and API responses are handled entirely in-memory or securely on the client side within the active session context, ensuring complete cryptographic transient isolation.

3. Data Sharing & Third-Party Non-Disclosure

We maintain absolute data privacy. No data accessed via Google OAuth scopes is shared, sold, rented, or transferred to third-party entities, advertising networks, or data brokers. All data transmissions are strictly point-to-point, encrypted in transit using industry-standard protocols, and limited entirely to the direct channel between the execution environment and Google's official API gateways.

For inquiries regarding this developer application, technical benchmarks, or verification compliance, please refer to the official documentation and repositories linked on this homepage (tanaikech.github.io).
