Guide - Data types in Streamscript

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

'Hi'

12.3

true

[ 'GenWatt', 'Burlington' ]

{ age: 24, medical: true }

'2023-01-31'

'2023-01-31T23:59:59.000Z'

'0010Q00001dMfMQQA0'

'JVBERi0xLjM=' # base64

{
  Name: 'GenWatt'
  IsDeleted: false
  NumberOfEmployees: 150
  attributes: {type: 'Account'}  
}

Variables

You can assign any data type to a variable:

$num = 123.4

Flow resources are already available within a script:

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

Collection Types

There is no need to declare variable types. All collection variables support mixed types within the collection, like this:

$items = [
  123.4
  'hello world'
]

Type Conversion

Sometimes integrations return data in an unexpected type. In these cases you can convert its type. For example:

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

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'
}
