typescript-simple

Just compile TypeScript code string to JavaScript. That's all!

Description

TypeScirpt 1.4 has official compiler API, but it isn't easy to compile tiny TypeScript code string. typescript-simple provides just one method that accepts TypeScript code string and returns JavaScript code.

Install

$ npm install typescript-simple

Usage

Simple usage (default target is ES5).

var tss = require('typescript-simple');
var js = tss('var n: number = 1;');
console.log(js); // 'var n = 1;'

If the code causes errors, typescript-simple throws errors.

try {
    var js = tss('var n: number = "str";');
} catch (e) {
    console.error(e); // Error: L1: Type 'string' is not assignable to type 'number'.
}

Specify compiler options.

var js = tss('var n: number = 1;', {noImplicitAny: true});

But tss() with options is not best-performance-method to be called many times. Use TypeScriptSimple class for the purpose.

var tss = new tss.TypeScriptSimple({target: ts.ScriptTarget.ES6, noImplicitAny: true});
var js1 = tss.compile('var n: number = 1;');
var js2 = tss.compile('var s: string = "foo";');

Limitaions

typescript-simple cannot compile multiple source files.

API

See index.d.ts.
