TypeScript Compiler Options Types

TypeScript declarations doesn't provide proper types for CompilerOptions that can be used to describe content of tsconfig.json file, instead, they provide internal representation of CompilerOptions, where enum values must be specified using numbers instead of strings. This modules closes this gap.

Typings in this module are based on both typings provided by TypeScript as well as official documentation.

If it's not working for your configuration or TypeScript version, please, create an issue.

Features

• provides CompilerOptions type that describes external compiler options as they are specified in tsconfig.json file and in online documentation with string enum values

• provides convertCompilerOptions utility function that converts compiler options from one format to another (both ways)

Installation

As development dependency

npm i -D @moebius/ts-compiler-options

As production dependency

npm i -S @moebius/ts-compiler-options typescript

Peer Dependencies

typescript package must be also installed in your project (we treat it as a peer dependency).

Usage

import {
  CompilerOptions,
  convertCompilerOptions,
  JsxEmit,
  ModuleKind,
  ModuleResolutionKind,
  NewLineKind,
  ScriptTarget,

} from '@moebius/ts-compiler-options';

const myOptions: CompilerOptions = {
  jsx: JsxEmit.React,
  module: ModuleKind.ES2015,
  moduleResolution: ModuleResolutionKind.Classic,
  newLine: NewLineKind.CarriageReturnLineFeed,
  outDir: '/dist',
  strict: true,
  target: ScriptTarget.ES2018,
};

console.log({ myOptions });

// Will produce:
//
// myOptions: {
//   jsx: 'react',
//   module: 'ES2015',
//   moduleResolution: 'Classic',
//   newLine: 'crlf',
//   outDir: '/dist',
//   strict: true,
//   target: 'ES2018',
// },
//

const convertedOptions = convertCompilerOptions(
  'external-to-internal',
  myOptions
);

console.log({ convertedOptions });

// Will produce:
//
// convertedOptions: {
//   jsx: 2,
//   module: 5,
//   moduleResolution: 1,
//   newLine: 0,
//   outDir: '/dist',
//   strict: true,
//   target: 5,
// },
//

const internalOptions = convertCompilerOptions(
  'internal-to-external',
  convertedOptions
);

// Will produce the same result as in first example
console.log({ internalOptions });
