Installation

Base Usage

1. Install packages.

npm i tst-reflect && npm i tst-reflect-transformer -D

2. In order to use transformer plugin you need TypeScript compiler which supports plugins eg. package ttypescript or you can use TypeScript compiler API manually.

npm i ttypescript -D

3. Add transformer to tsconfig.json

{
    "compilerOptions": {
        // your options...

        // ADD THIS!
        "plugins": [
            {
                "transform": "tst-reflect-transformer"
            }
        ]
    }
}

4. Now just transpile your code by ttsc instead of tsc

npx ttsc

Using Webpack

Modify your webpack config. Use options.compiler of ts-loader to set ttypescript compiler.

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

Using Parcel

Install Parcel plugin.

npm i parcel-plugin-ttypescript

Using Rollup

Install Rollup plugin

npm i rollup-plugin-typescript2

and modify your rollup config.

import ttypescript from "ttypescript";
import tsPlugin from "rollup-plugin-typescript2";

export default {
    // your options...
    
    plugins: [
        // ADD THIS!
        tsPlugin({
            typescript: ttypescript
        })
    ]
}

Using ts-node

Modify your tsconfig.json.

{
    "compilerOptions": {
        // your options...

        "plugins": [
            {
                "transform": "tst-reflect-transformer"
            }
        ]
    },
    
    // ADD THIS!
    "ts-node": {
        // This can be omitted when using ts-patch
        "compiler": "ttypescript"
    },
}
