A lot of users try and quickly learn GAS and use it to make their lives easier. It’s all great, however the code we sometimes tend to come across on StackOverflow and other sites lacks best practices, hence I thought it was time to start bringing them up and I will start today with design patterns.
I’m all for copy/paste coding and it one of the things I love about the Google Apps Script developer community, there are lots of great snippets out there and in Pulse we’ve now over 800 posts and counting. When you start going beyond quick script solutions into more complex projects investing time planning how you’ll structure your code can save you headaches and frustrations further down the line.
Using design patterns are one way to produce better code that is more readable which in turn is more maintainable and can lead to faster development. This post from Dmitry Kostyuk a nice opportunity to learn about a design pattern for a very common use case of maintaining data in a Google Sheet from a third party API.
When working in a team and/or with a client, you want to have multiple environments. At minimum, you probably want a dev environment (or multiple ones) in which you are working, and a test environment in which the client or your team can run acceptance tests before production. Of course, they must both be separate from the production environment. To push your code to the correct environment, you need to either update the
file manually or keep multiple copies of your script with different
files. Fortunately, things have just become significantly easier, as I recently built an app for this purpose called
clasp-env, which is available on NPM. See the source link for details.
According to Wikipedia, the Game of Life “is a cellular automaton devised by the British mathematician John Horton Conway in 1970.”
It begins on a two-dimensional grid of square cells. Each cell can be either alive or dead. Every cell interacts with its eight immediate neighbors. A live cell only remains alive if it has two or three living neighbors. If it has fewer than two living neighbors, it dies as if by underpopulation. Conversely, if it has more than three, it dies as if by overpopulation. A dead cell remains dead unless it has exactly three living neighbors; otherwise, it becomes a live cell, as if by reproduction.
There is no immediate practical use for the Game of Life in a spreadsheet; however, it is a fun algorithmic challenge. Moreover, Google Sheets natively provides us with the perfect data structure: a two-dimensional array. This is all the more reason to work on those array skills!
Google Apps Script has some amazing built-in stuff. It gives us native access to all Google apps like Sheets and Gmail, seamlessly integrates with GCP services like BigQuery, allows for the building of interfaces with HTML and CardService, facilitates the creation of simple webhooks/APIs and web apps with simple and efficient client-server communication, can make use of any API through
, and can be bundled into add-ons for efficient distribution. In my experience, it’s enough for 99% of all Google Apps Script developers.
But what if I told you that there actually is a way to use some NPM modules in Apps Script? You just need to bundle them with Webpack. Not sure what I mean? Keep reading.
Do you still spend time every day monitoring your sales report, identifying which customer subscription is going to expire soon, and manually draft an email to send out to your customer? Would it be better if this manual task can be automated every day for you? If that’s the case, this article can be a great help for you!
Following on from some recent Google Sheet payment solutions here’s a tutorial that highlights how you can use Sheets and Apps Script as a payment reminder tool. Combine with Stripe or Razorpay and you have a complete subscription management solution.
Build your own functions in Google Sheets that do anything you need them to in a few lines of code.
This is a great tutorial if you are interested in finding out more about developing custom functions in Google Sheets. The post includes everything you need to get started from handling single cell and range inputs, to documenting your function so that users see inline help.
