Using Design Patterns in Google Apps Script – Introduction to façade and proxy patterns

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.

As noted by the post author Dmitry Kostyuk the Google Apps Script V8 runtime opens up many new coding opportunities previously not available to Apps Script developers. Using the common use case, fetching data and writing it to a Google Sheet, Dmitry explains how the façade and proxy code patterns can be used to write efficient easy-to-read code.

Adding an unsubscribe link to the Google Workspace Solution Gallery ‘Mail merge using Gmail and Google Sheets’

Recently I came across a nice post from Ravgeet Dhillon, which looked at how to Add Unsubscribe link in emails using Google Apps Script. The solution uses a Google Sheet and a Google Apps Script web app to add an unsubscribe link to emails. As I noted when shared via AppsScriptPulse this is a useful addition if your mailing needs comply with PECR or similar electronic communications regulation compliance.

Having recently updated my ‘Create a mail merge using Gmail and Google Sheets’ in the Google Workspace Solution Gallery to handle inline images I thought it would be useful to show how this example can be extended to include a variation on Ravgeet’s post.
