Hi CF users and members of the community. I am reaching to you for some help in identifying some real world use cases for serializeJSON in CF. I am intending to revamp the page, make it more user friendly, and replace the existing sampes with some solid, real-world samples. As a developer with deep CF expertise, how do you use serializeJSON? What are its typical use cases?

As Lucee is open source, you can see all out test cases, some of which arise from feature development and others are in response to bugs raised by users at the bottom of every page in lucee docs is a link to search our test cases on github https://docs.lucee.org/reference/functions/serializejson.html

Thank you @zackster I'll take a look. Thanks!

@saghosh most important to that site's examples is demonstrated in this example code for SerializeJSON:

<!--- Generate a clean feed by suppressing white space and debugging
information. --->
<cfprocessingdirective suppresswhitespace="yes">
<cfsetting showdebugoutput="no">
<!--- Generate the JSON feed as a JavaScript function. --->
<cfcontent type="application/x-javascript">
<cfscript>
// Construct a weather query with information on cities.
// To simplify the code, we use the same weather for all cities and days.
// Normally this information would come from a data source.
weatherQuery = QueryNew("City, Temp, Forecasts");
QueryAddRow(weatherQuery, 2);
theWeather=StructNew();
theWeather.High=73;
theWeather.Low=53;
theWeather.Weather="Partly Cloudy";
weatherArray=ArrayNew(1);
for (i=1; i<=5; i++) weatherArray[i]=theWeather;
querySetCell(weatherQuery, "City", "Newton", 1);
querySetCell(weatherQuery, "Temp", "65", 1);
querySetCell(weatherQuery, "ForeCasts", weatherArray, 1);
querySetCell(weatherQuery, "City", "San Jose", 2);
querySetCell(weatherQuery, "Temp", 75, 2);
querySetCell(weatherQuery, "ForeCasts", weatherArray, 2);
// Convert the query to JSON.
// The SerializeJSON function serializes a ColdFusion query into a JSON
// structure.
theJSON = SerializeJSON(weatherQuery);
// Wrap the JSON object in a JavaScript function call.
// This makes it easy to use it directly in JavaScript.
writeOutput("onLoad( "&theJSON&" )");
</cfscript>
</cfprocessingdirective>

Only line 30 of all that mess is relevant to

serializeJson

. Show these variants: • serialise a struct. Point out the key-case issue. • serialize a query (but create the query with a single

queryNew

call!!), and show how the columns / rows are handled, for both variants of

queryFormat

• serialize a datetime, and show the resultant format • serialize null. • demonstrate that beyond the value of a Long, a numeric is serialized as a string (TIL...)

I agree Adam. Hence the effort to revamp this.

You don't need or want "real-world" examples. Demonstrate the variants of the behaviour

What I meant by real-world is that the examples should be clear enough for CF devs, but not too simplistic or trivial.

q = queryNew("id,value", "integer,varchar", [
    [1, "one"],
    [2, "two"],
    [3, "three"]
])

writeOutput(serializeJson(q))

Demonstrating serializing a query. And follow up with the output and explain what they're looking at.
