+# 🧰 Simple TypeScript Starter | 2020
+
+> We talk about a lot of **advanced Node.js and TypeScript** concepts on [the blog](https://khalilstemmler.com), particularly focused around Domain-Driven Design and large-scale enterprise application patterns. However, I received a few emails from readers that were interested in seeing what a basic TypeScript starter project looks like. So I've put together just that.
+
+### Features
+
+- Minimal
+- TypeScript v4
+- Testing with Jest
+- Linting with Eslint and Prettier
+- Pre-commit hooks with Husky
+- VS Code debugger scripts
+- Local development with Nodemon
+
+### Scripts
+
+#### `npm run start:dev`
+
+Starts the application in development using `nodemon` and `ts-node` to do hot reloading.
+
+#### `npm run start`
+
+Starts the app in production by first building the project with `npm run build`, and then executing the compiled JavaScript at `build/index.js`.
+
+#### `npm run build`
+
+Builds the app at `build`, cleaning the folder first.
+
+#### `npm run test`
+
+Runs the `jest` tests once.
+
+#### `npm run test:dev`
+
+Run the `jest` tests in watch mode, waiting for file changes.
+
+#### `npm run prettier-format`
+
+Format your code.
+
+#### `npm run prettier-watch`
+
+Format your code in watch mode, waiting for file changes.
