0.9 includes improvements to some of our provider code bindings, to improve usage across all languages.

Standardize IResolvable Usage

PR: #1299 This is an effort to make sure attributes can be freely passed between resources for all different types. There is a minor breaking change:
  • count on resources and data sources has gone from number | cdktf.IResolvable to number. If code was previously passing an IResolvable, it will now need to wrap the IResolvable using Token.asNumber() on Typescript and Java , Token.AsNumer() on C#, cdktf.Token_AsNumber() on Go, and Token().as_string() on Python.

Map Tokens

PR: #1411 As part of an effort to use more native types, there are now tokens for maps of primitive values. As a result, there is a minor breaking change:
  • Map attributes have gone from { [key: string]: TYPE } | cdktf.IResolvable to { [key: string]:TYPE } when TYPE is string, number, or boolean.
    • The most common impact is maps created by using Terraform functions (Fn.(...)) will now need to be passed to Token.as<String/Number/Boolean>Map() before assigning to a resource attribute. The naming is a bit different per language, on C# it’s Token.As<String/Number/Boolean>Map(), on Go it’s cdktf.Token_As<String/Number/Boolean>Map(), and on Python it’s Token().as_<string/number/boolean>_map().

Number[] Tokens

PR: #1471 As part of an effort to use more native types, there are now tokens for number[]. This is mostly an internal change, but there is now Token.asNumberList() (on C# it’s Token.AsNumberList(), on Go it’s cdktf.Token_AsNumberList, on Python it’s Token().as_number_list()) which can be used to convert other values into number[]. As a result of some standardization, there is a minor breaking change:
  • Boolean[] attributes have gone from boolean[] to Array<boolean | IResolvable> | IResolvable.
    • This is done because neither boolean or boolean[] is representable by a token.
    • This should make it easier to pass around boolean[] between resources and fuctions.
    • For jsii languages (especially Java and C#), these types will end up as List<Object>.
