# Installation

## 1. Add tRPC-Nuxt to existing Nuxt project

::code-group

```bash [pnpm]
pnpm add @trpc/server@next @trpc/client@next trpc-nuxt@next zod
```

```bash [npm]
npm install @trpc/server@next @trpc/client@next trpc-nuxt@next zod
```

```bash [yarn]
yarn add @trpc/server@next @trpc/client@next trpc-nuxt@next zod
```

::

#### Why @trpc/server?

For implementing tRPC endpoints and routers.

#### Why @trpc/client?

For making typesafe API calls from your client.

#### Why zod?

Most examples use [Zod](https://github.com/colinhacks/zod) for input validation and tRPC.io highly recommends it, though it isn't required.

## 2. Enable strict mode

If you want to use Zod for input validation, make sure you have enabled strict mode:

::code-group

```json [tsconfig.json]
{
  "extends": "./.nuxt/tsconfig.json",
  "compilerOptions": {
    "strict": true
  }
}
```

```ts [nuxt.config.ts]
export default defineNuxtConfig({
  typescript: {
    strict: true
  }
})
```

::

If strict mode is too much, at least enable `strictNullChecks`:

::code-group

```json [tsconfig.json]
{
  "extends": "./.nuxt/tsconfig.json",
  "compilerOptions": {
    "strictNullChecks": true
  }
}
```

```ts [nuxt.config.ts]
export default defineNuxtConfig({
  typescript: {
    tsConfig: {
      strictNullChecks: true
    }
  }
})
```

::

## Next Steps

Now that you've installed the required dependencies, you are ready to start building your application.
