dts2as logo

dts2as

A command line utility that converts TypeScript definitions (d.ts files) for JavaScript libraries into SWC files. Use these SWCs with Apache FlexJS for strict compile-time type checking, as if the JavaScript library were written in ActionScript. Add the SWCs to IDEs, like Flash Builder and IntelliJ IDEA, and you'll get helpful code suggestions as you type.
