Google Apps Script Bulk Set Properties - properties

Question

Another GAS question. I read the documentation on ScriptProperties and bulk-setting properties, as well as (again) the documentation on best practices. However, I'm not familiar with Javascript, and still new to GAS, and I keep running over the rate limit for API calls as a result.
Basically, I would like to 'get' all these properties from the Spreadsheet, put them in an Array or Object or something, then bulk set all of them. I have the keys and values correct, I just don't know how to temp store them in a JS Object or Array or some data type that will be accepted by the setProperties(Object) method.
Here is the current code (horrendous Sleep timer is the only thing that is working...):
function setSubsequentProperties(propertyRange, sheet) {
// Get the other Library Properties based on the new Range values.
// propertyRange is the 2-column 1-row Range for the key/value pairs
var tableRange = ScriptProperties.getProperty(propertyRange);
var dataRange = sheet.getRange(tableRange);
var data = dataRange.getValues();
// Create a 'properties' Object for bulk-setting to prevent overusing API calls
//var properties = new Array(data.length);
// Set a new Script Property for each row
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var propertyKey = row[0];
var propertyValue = row[1];
// var myObject = allMyPropertiesInOneObject
ScriptProperties.setProperty(propertyKey, propertyValue);
Utilities.sleep(1000);
}
// setProperties(myObject);
}
How might I go about adding propertyKey and propertyValue to an Object to bulk set them all at once? The pseudo-idea is commented out in the code block.

Answer 1

Since you say you are new to Javascript, I assume you are new to JSON as well. There is indeed a ScriptProperties.setProperties() method which takes a JSON object as argument.
Modifying just the setProperty() bit of your code, here is what you can do
function setSubsequentProperties(propertyRange, sheet) {
// Get the other Library Properties based on the new Range values.
// propertyRange is the 2-column 1-row Range for the key/value pairs
var tableRange = ScriptProperties.getProperty(propertyRange);
var dataRange = sheet.getRange(tableRange);
var data = dataRange.getValues();
// Create a 'properties' Object for bulk-setting to prevent overusing API calls
//var properties = new Array(data.length);
// Set a new Script Property for each row
var myObject = {} ;
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var propertyKey = row[0];
var propertyValue = row[1];
// var myObject = allMyPropertiesInOneObject
myObject[propertyKey] = propertyValue;
}
ScriptProperties.setProperties(myObject);
}

Just to update this answer, Google has deprecated ScriptProperties and replaced it with the PropertiesService. You can solve the same problem using setProperties() on a Properties object, except you have to choose which kind of store you want using a call to PropertiesService first:
var myObject = {} ;
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var propertyKey = row[0];
var propertyValue = row[1];
myObject[propertyKey] = propertyValue;
}
var myProperties = PropertiesService.getScriptProperties(); // or getUserProperties() or getDocumentProperties()
myProperties.setProperties(myObject);
See the documentation for details. Note: this only seems to work for simple key/value pairs. When I try to set and get more complex JSON objects, with keys set to arrays of values, I can retrieve the object but not the values inside it. I can't use JSON.parse() on it successfully, either. I'll post again if I can figure it out.
