Data Types in Streamscript

Streamscript supports all data types on all objects, including standard, custom, managed, platform events, custom metadata, wher the running user has CRUD and FLS permissions.

Text	'Hi'
Number	12.3
Boolean	true
List	[ 'GenWatt', 'Burlington' ]
Map	{ age: 24, medical: true }
Date	'2023-01-31'
Date/Time	'2023-01-31T23:59:59.000Z'
ID	'0010Q00001dMfMQQA0'
Binary Blob	'JVBERi0xLjM=' # base64
SObject	{ Name: 'GenWatt' IsDeleted: false NumberOfEmployees: 150 attributes: {type: 'Account'} }

Variables

Data from any of the types may be assigned to a variable like this:

$num = 123.4

Flow resources are already available within a script - for example:

$Contact = {!$Record}
$greeting = `Hello $Contact.Name`
$message = `$greeting \n Form submitted at {!$Flow.InterviewStartTime}`

Collection Types

There is no requirement to define the type of data assigned to a variable. All collection variables support mixed types within the collection, like this:

$items = [
  123.4
  'hello world'
]

Type Conversion

You may have integrations that receive data in a different type than intended. In these cases you can convert its type. Here are some typical examples:

Map to Text

$map = {first: 'Peter', last: 'Hopkins', medical: true, age: 24}
$url = $map.toUrl()  # 'first=Peter&last=Hopkins&medical=true&age=24'

Text to Number

$text = '124.3'
$number = $text.toNumber()  # 124.3

Value to Boolean

$num = 1
$text = 'false'
$bool1 = $num.toBoolean()  # true
$bool2 = $text.toBoolean()  # false

Text to Maps

$json = '[{"name":"peter","age":23},{"name":"jane","age":19}]'
$maps  = Json-Decode $json
$ageOfJane = $maps.1.age  # 19

List to Text

$list = [192, 168, 1, 10]
$ipAddress = $list.join('.')  # 192.168.1.10

All type convert methods are listed in the reference: Type Convert Methods

JSON Types

Any valid JSON value is also a valid Streamscript value. For example:

# JSON - valid Streamscript
$map = {
  "age": 24,
  "medical": true,
  "name": "Hopkins"
}

Commas are optional. For example:

# Also - valid Streamscript
$map = {
  age: 24
  medical: true
  name: 'Hopkins'
}
