 Enhance uses [Architect](https://arc.codes) under the hood for local development and deployment. It is possible to migrate between a typical Architect project structure and the Enhance file-based routing. It is also possible to mix the two approaches together in the same app. They are incrementally adoptable in both directions.

 Enhance can be used to render Markdown with minimal effort — in fact, this very site is itself an Enhance app that renders Markdown to HTML on demand. You can dig into the [source code](https://github.com/enhance-dev/enhance.dev) to see exactly how we've set it up, or follow along below.

+title: Translate React syntax to Enhance elements
+---
+
+We’re often asked by React developers why patterns they’ve learned while writing JSX don’t translate to writing web components. In this doc, we’ll describe some common gotchas that developers coming from React or other JavaScript frameworks may run into when writing plain vanilla web components.
+
+## String Interpolation

+<doc-code filename="JavaScript">
+
+```javascript
+const element = `<h1>${title}</h1>`;

+<doc-code filename="React">
+
+```javascript
+const element = <h1>{title}</h1>;
+```

+```

+
+## Rendering Markup from Arrays

+const todoList = `<ul>
+  ${todos.map((todo) => (

+  ))}
+</ul>`
+```

 An event is a signal that something has happened on your page. The browser notifies you so you can react to them.

+title: Use TypeScript
+---
+
+If you prefer to work with TypeScript, we recommend starting with our [TypeScript starter project](https://github.com/enhance-dev/enhance-starter-typescript).
+
+
+## Getting Started
+
+Assuming you’re starting a new Enhance project, you would run the command:
+
+```bash
+npx "@enhance/cli@latest" new ./myproject \
+  --template https://github.com/enhance-dev/enhance-starter-typescript -y
+```
+
+This will set up a new Enhance project where you’ll code your APIs, elements and pages in TypeScript instead of JavaScript. Instead of editing files in the `app` folder, you’ll do your editing in the `ts` folder.
+
+
+### Project Structure
+
+``` \
+ts
+├── api ............... data routes
+│   └── index.mts
+├── browser ........... browser JavaScript
+│   └── index.mts
+├── components ........ single file web components
+│   └── my-card.mts
+├── elements .......... custom element pure functions
+│   └── my-header.mts
+├── pages ............. file-based routing
+│   └── index.html
+└── head.mts .......... custom <head> component
+```
+
+Note: We are using `.mts` to tell the TypeScript Compiler to generate ES Modules as `.mjs` files..
+
+
+## Local Development
+
+Running the local development environment is the same as any other Enhance project. The new `@enhance/plugin-typescript` is responsible for watching the `ts` folder for any file changes. If a file with an `.mts` extension is updated, it will be re-compiled with the compilation target being the `app` folder. All other file types are simply copied to their corresponding locations in the `app` folder.
+
+## Authoring Code
+
+Write your code in TypeScript. We already have [types](https://github.com/enhance-dev/types) that you can import into your elements:
+
+<begin-code filename="ts/api/todo-item.mts">
+
+```typescript
+import type { EnhanceElemArg } from "@enhance/types"
+
+export default ({ html, state: { attrs } }: EnhanceElemArg) => {
+  const { state = "" } = attrs
+  return html`
+    ${state === "complete" ? "☑" : "☐"}
+    <slot></slot>
+  `
+}
+```
+
+</begin-code>
+
+Or APIs:
+
+<begin-code filename="ts/api/todos.mts">
+
+```typescript
+import type {
+  EnhanceApiFn,
+  EnhanceApiReq,
+  EnhanceApiRes,
+} from "@enhance/types";
+
+type Todo = {
+  title: string;
+  completed?: boolean;
+};
+
+export const get: EnhanceApiFn = async function (
+  request: EnhanceApiReq,
+): Promise<EnhanceApiRes> {
+
+  console.log(`Handling ${request.path}...`);
+
+  const todos: Todo[] = [
+    { title: "todo 1", completed: false },
+    { title: "todo 2", completed: true },
+    { title: "todo 3" },
+  ];
+
+  const response: EnhanceApiRes = {
+    json: { todos },
+  };
+
+  return response;
+};
+```
+
+</begin-code>
+
+## Deploying
+
+Use the [`@begin/deploy`](https://begin.com/deploy/docs/workflows/deploying-code) package to deploy your application. Alternatively, you can write a GitHub Action to [deploy on every commit](https://github.com/enhance-dev/enhance-starter-typescript/blob/main/.github/workflows/CI.yml).

 A big benefit of Enhance custom element [pure functions](https://en.wikipedia.org/wiki/Pure_function) is that they return a string that you can test against an expected output. It doesn't need to get any more complicated than that to get started.
