Features
TypeScript Support
The jsii compiler leverages the original TypeScript compiler API to compile TypeScript source files and produce
JavaScript output and TypeScript declaration files, while also extracting the compiled module's API signatures in
a jsii assembly file.
To determine the version of TypeScript that is in use by the installed release of jsii, simply look at the
jsii --version output:
# jsii --version
1.15.0 (build 585166b), typescript 3.9.7
You can then refer to the TypeScript documentation to determine which language features are available in that specific TypeScript release.
Warning
The jsii compiler imposes some restrictions on what TypeScript features can be used to declare the APIs
exported by a jsii module, in order to ensure those APIs can be consistently represented in other languages. For
more information, refer to the TypeScript Restrictions page.
