Package Exports

ttypescript
ttypescript/lib/tsc.js

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

What it is

Currently TypeScript doesn't support custom transformers in the tsconfig.json, but supports its programatically.

And there is no way to compile your files using custom transformers using tsc command.

TTypescript (Transformer Typescript) solves this problem by patching on the fly the compile module to use transformers from tsconfig.json.

How to install

npm i ttypescript --save
npm i -g ttypescript

ttypescript uses your installed typescript in your node_modules

How to use

tsconfig.json

You just need to add the customTransformers block with before and(or) after object contains array of transformer paths into the compilerOptions

{
  "compilerOptions": {
   "customTransformers": {
      "before": [
        "transformermodule"
      ],
      "after": [
        "./or_some_path_in_your_project_directory"
      ]
    }
  }
}

Command line

Like usual tsc, all arguments work the same way.

ttsc

ts-node

ts-node --compiler ttypescript index.ts
or
ts-node -C ttypescript index.ts

Webpack

    {
        test: /\.(ts|tsx)$/,
        include: paths.appSrc,
        loader: require.resolve('ts-loader'),
        options: {
            compiler: 'ttypescript'
        }
    }

Visual Studio Code

Set the config typescript.tsdk to /usr/local/lib/node_modules/ttypescript/lib/

WebStorm

Set in the TypeScript settings tab the typescript path: /usr/local/lib/node_modules/ttypescript or from your project node_modules
