# Installation

> Install Zod in your Node.js, Deno, or Bun project

## Package Manager Installation

Install Zod using your preferred package manager:

<CodeGroup>
  ```bash npm theme={null}
  npm install zod
  ```

  ```bash yarn theme={null}
  yarn add zod
  ```

  ```bash pnpm theme={null}
  pnpm add zod
  ```

  ```bash bun theme={null}
  bun add zod
  ```
</CodeGroup>

## Requirements

<Note>
  Zod requires TypeScript 4.5+ for the best experience. You can use Zod with plain JavaScript, but you'll miss out on static type inference.
</Note>

* **TypeScript**: 4.5 or higher (recommended)
* **Node.js**: Works with all modern versions
* **Browsers**: Works in all modern browsers

## Runtime-Specific Setup

### Node.js

Zod works out of the box with Node.js. Just import it in your code:

```typescript theme={null}
import * as z from "zod";

// or using CommonJS
const z = require("zod");
```

### Deno

You can import Zod directly from npm in Deno:

```typescript theme={null}
import * as z from "npm:zod@latest";

const schema = z.string();
schema.parse("hello");
```

<Tip>
  Deno has built-in TypeScript support, so you get full type inference without additional configuration.
</Tip>

### Bun

Bun has native support for npm packages:

```bash theme={null}
bun add zod
```

Then import as usual:

```typescript theme={null}
import * as z from "zod";

const schema = z.number();
schema.parse(42);
```

## Verify Installation

Create a simple test file to verify Zod is installed correctly:

```typescript test.ts theme={null}
import * as z from "zod";

const schema = z.string();

try {
  const result = schema.parse("hello");
  console.log("Success:", result);
} catch (error) {
  console.error("Error:", error);
}
```

Run the file:

<CodeGroup>
  ```bash Node.js theme={null}
  node test.ts
  ```

  ```bash Deno theme={null}
  deno run test.ts
  ```

  ```bash Bun theme={null}
  bun test.ts
  ```
</CodeGroup>

You should see:

```
Success: hello
```
