Google Apps Script (GAS) is not just another application development platform; it’s a powerful JavaScript library tailored to interact seamlessly with the G Suite applications such as Google Sheets, Google Docs, Google Slides, Google Calendar, and Gmail. Imagine creating a custom function in Google Sheets that automatically formats your data, or a script in Google Docs that translates your content into a predefined language. Perhaps you’d like to automate email workflows in Gmail based on certain triggers. With GAS, you can create bespoke solutions like these and derive maximum value from the G Suite ecosystem.
Key features and benefits of GAS
These are some of GAS standout features:
- Custom Menus in G Suite Apps: Add personalized menus in Google Sheets or Docs to launch your specific scripts with ease.
- Automate Workflows: Craft scripts to automatically send Gmail messages based on defined criteria, streamlining everyday tasks.
- Integrate Google Services: Seamlessly merge data between Sheets and Google Contacts, or let form entries instantly generate events in your Google Calendar.
- Web App Development: Create and roll out web applications tailored for both internal and external users using GAS.
The adoption of GAS also brings forth a number of tangible benefits:
- Cost-Efficiency: Eliminate the need for costly third-party integrations with this free offering from Google.
- Flexibility: Customize solutions to meet specific requirements.
- Security: Rely on the robust security infrastructure that Google provides for its applications.
The Challenge: GAS’s Built-in IDE
While GAS provides an integrated development environment (IDE) that facilitates quick scripting, it’s not without its limitations. Developers often find challenges in:
- Synchronizing their scripts with platforms like GitHub.
- The absence of features that are standard in popular editors like Visual Studio Code.
- Organizing complex codebases efficiently.
The Solution: clasp
Enter clasp (Command Line Apps Script Projects), a game-changing tool for GAS developers. At its core, clasp acts as a bridge, connecting the proprietary environment of GAS’s IDE with the vast world of modern local editors.
Here’s how clasp has eased the GAS development process:
Local Development: By synchronizing with the GAS remote repository,
clasplets you develop scripts on your local machine. This means you’re no longer confined to the online IDE; instead, you can work in the familiar environment of your preferred local editor, be it Visual Studio Code, Atom, Sublime, or any other. This not only enhances productivity but also makes coding more enjoyable and efficient. Modern editors come packed with extensions and tools that can aid in development, from linting and formatting to advanced debugging. Withclasp, GAS developers can leverage these tools, resulting in cleaner and more efficient code.Version Control: With your codebase now local, it becomes vastly simpler to manage version control. Traditional tools like
gitcan be employed, offering powerful tracking, branching, and collaboration capabilities.Push to Popular Repositories: Having your GAS projects stored locally allows them to tap into the collaborative and open-source advantages offered by platforms like GitHub.
At its core, clasp dismantles the limitations of GAS’s IDE, offering developers the flexibility and resources inherent in modern IDEs. The diagram below illustrates a potential integration setup facilitated by clasp. In this model, GAS’s IDE seamlessly syncs with Visual Studio Code, which concurrently manages the code base stored in a GitHub Remote Repository.
Setting Up clasp: A Step-by-step Guide
To help you integrate clasp into your GAS development process, here’s a detailed walkthrough:
1.Install Node.js and NPM
Ensure you have Node.js (version 4.7.4 or later). Download the installer for your platform here.
After installation, validate with:
1node -v
2npm -v
2. Install clasp
For MacOS or Linux:
1sudo npm i @google/clasp -g
If you are using Windows, open the terminal with the action Run as administrator:
1npm i @google/clasp -g
Post-installation, verify with clasp -v.
3. Activate the Google Apps Script API
Navigate to the Apps Script Settings page, click on Google Apps Script API and toggle the switch to On.
4. Authenticate clasp with Your GAS Account
Execute clasp login and follow the browser instructions.
1clasp login
5. Initialise a Node Project
Execute:
1npm init
The end result will be a new package.json file.
6. Retrieve Your GAS Project Files
Use:
1clasp clone + “[ID of your GAS project]”
Locate the ID in your GAS remote repository settings:
As a result, all your GAS files will be created locally on your computer. This will allow you to access them via your preferred IDE.
Note: Local GAS files use the .js extension, but clasp handles the conversion to .gs seamlessly.
7. Push changes to the GAS Remote Repository
Once you have written some code, you can deploy it to the GAS Remote Repository with:
1clasp push
Optionally, you can create a .claspignore file to list the files that should not be pushed into the GAS Remote Repository.
Alternitely, you can use clasp push -w. This option stands for watch and it allows clasp to push the code every time you save the file you’re working on, so you don’t have to run the clasp push command every time.
1clasp push -w
You can stop the terminal from listening to changes by pressing Ctrl + C on your keyboard.
8. Pull changes from the GAS Remote Repository into your local machine
Use the clasp pull command to fetch the latest from the GAS Remote Repository:
1clasp pull
Conclusion
Harnessing the power of Google Apps Script can revolutionize the way you interact with G Suite applications. Coupled with clasp, the potential to innovate, automate, and optimize becomes boundless. Whether you’re on a quest to amplify efficiency in your daily tasks or to dive deep into the world of automation, GAS and clasp offer the resources to transform your ideas into reality.
