TypeScript with exposed internal definitions and some private methods for type checking.

Package Exports

  • unleashed-typescript
  • unleashed-typescript/lib/index.cjs

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 (unleashed-typescript) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

unleashed-typescript

TypeScript with exposed internal definitions and some private methods for type checking.

How does it work?

When you install the package, it will look for your local version of TypeScript. It will then make a copy of your version in its own location, apply the patches and re-export the patched version. Then you can import the patched version and enjoy your unleashed version of TypeScript while keeping your original version intact.

What does it add/remove?

  1. Removes all @internal tags which allows you to access internal types, classes, properties and methods with their declarations.

  2. Export some very useful private methods from the TypeChecker:

    function isTypeSubtypeOf(source: Type, target: Type): boolean;
function isTypeIdenticalTo(source: Type, target: Type): boolean;
function isTypeDerivedFrom(source: Type, target: Type): boolean;
function isTypeAssignableTo(source: Type, target: Type): boolean;
function isTypeComparableTo(source: Type, target: Type): boolean;
function areTypesComparable(source: Type, target: Type): boolean;
    And many other things... 
    interface OptionsNameMap;

function getOptionsNameMap(): OptionsNameMap;

interface CommandLineOptionOfCustomType;
interface CommandLineOptionOfStringType;
interface CommandLineOptionOfNumberType;
interface CommandLineOptionOfBooleanType;
interface TsConfigOnlyOption;
interface CommandLineOptionOfListType;

type CommandLineOption;

Installation

pnpm add -D typescript unleashed-typescript
import ts from 'unleashed-typescript';

// Use ts as usual.

CLI

With no arguments unleashed-typescript patches your current version of typescript if it is not already patched. If you want to sync your version after an update you can use the --force-patch option.

Usage: pnpm unleashed-typescript [options]

Options:
  --unpatch       Revert the patch (useful before a build/publish).
  --force-patch   Force patch from your current typescript version.

Alternatives

unleashed-typescript is a combination of the alternatives listed below. But instead of maintaining an up-to-date build of TypeScript we use your locally installed version.

Remove @internal tags

  • byots Bring your own TypeScript with more internal definitions
  • ts-expose-internals Expose TypeScript internal types by simply adding a development dependency
