ts_interop #

Creates Dart interop types for JavaScript based on TypeScript declaration files.

Introduction #

• Read TypeScript AST of a .d.ts file and write it as a JSON structure (done in ts-ast-export).
• Read JSON structure in Dart to a tree of TsNode objects.
• Sanitize the tree to fix types not mappable to the Dart type system.
• Transpile tree to a tree of DartNode objects.
  • Mostly Spec objects from the code_builder package.
• Write Dart source to an output file.

Command line interface #

Using this package as a dependency #

Roadmap #

• Use Dart core types like String num etc. where posible
• Create types for unions and anonymous functions like https://gist.github.com/nikeokoronkwo/dd83becbb6cee4d98f63556ba108e14b
• Replace meta.json by translating Dart code into input AST
• Integrate ts-ast-export into cli tool.
