Package Exports

typescript-simple
typescript-simple/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (typescript-simple) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

typescript-simple

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

Description

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

Install

$ npm install typescript-simple

Usage

Simple usage.

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

Specify compiler options.

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

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

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

API

compile(code: string, options?: typescript.CompilerOptions): string

code: TypeScript input source code string
options: TypeScript compiler options
return : JavaScript output code string

Following is full compiler options, but some are ignored in the current implementation.

interface CompilerOptions {
    allowNonTsExtensions?: boolean;
    charset?: string;
    codepage?: number;
    declaration?: boolean;
    diagnostics?: boolean;
    emitBOM?: boolean;
    help?: boolean;
    locale?: string;
    mapRoot?: string;
    module?: ModuleKind;
    noEmitOnError?: boolean;
    noErrorTruncation?: boolean;
    noImplicitAny?: boolean;
    noLib?: boolean;
    noLibCheck?: boolean;
    noResolve?: boolean;
    out?: string;
    outDir?: string;
    preserveConstEnums?: boolean;
    removeComments?: boolean;
    sourceMap?: boolean;
    sourceRoot?: string;
    suppressImplicitAnyIndexErrors?: boolean;
    target?: ScriptTarget;
    version?: boolean;
    watch?: boolean;
