Step-by-step guide to minify Typescript files with Webpack

I am facing an issue in my webpack configuration while trying to minify the output bundle when working with TypeScript. Currently, only one file has been migrated to TypeScript in my project and it works fine with babel-node and the dev bundle without Uglify. But, as soon as I switch to the prod bundle, I encounter the following error:

ERROR in main.ab0b2e37030c63351bb8.js from UglifyJs
SyntaxError: Unexpected token: name (App) [./components/App.ts:12,0]

This is how my webpack config looks like:

const config = {
  // Your webpack configuration goes here
};

// Your App.ts code snippet goes here

export default App

Answer №1

The reason for this issue is that the UglifyJsPlugin currently supports only es5, while you may be using es6 or es2017. Please review your tsconfig.json configuration to ensure it is set up to utilize es5.
