$ npm install --global reasonably-typed
Converts TypeScript and Flow definitions to Reason interfaces
(Also maybe TypeScript definitions to Flow)
// 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; } }
$ retyped class.js
/* 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"; };
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:// 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
