$ npm install --global reasonably-typed

Converts TypeScript and Flow definitions to Reason interfaces
(Also maybe TypeScript definitions to Flow)

Take your Flow or TypeScript definition

```js // class.js declare module 'classes' { declare type State = { id: number, storeName: string, } declare export class Store { constructor(initialState: State): Store; state: State; update(nextState: State): void; } } ```

Run retyped

$ retyped class.js

Get Reason

```reason /* Module classes */ type state = {. "id": float, "storeName": string }; module Store = { type t = {. "state": (state), "update": [@bs.meth](state => unit)}; [@bs.new] [@bs.module "classes"] external make : state => t = "Store"; }; ``` ## Docs

Examples

TypeScript TypeScript has a similar workflow. Compile your TypeScript file with: ``` $ retyped my-definition.d.ts ```

Command-line Usage ``` Usage: $ retyped ...files Examples: $ retyped file1.js file2.js file3.d.ts [boolean] ```

Usage as a library ReasonablyTyped also exports a library for use! See the example below: ```js // lib-usage.js import * as ReasonablyTyped from 'reasonably-typed' const libSrc = fs.readFileSync('lib.js').toString() const bsInterface = ReasonablyTyped.compile(libSrc) ``` **`format (code: string) => string`** Formats a block of code using `refmt` **`compile (code: string, filename?: string) => string`** Compiles a libdef, formats the result, and handles errors cleanly
