Integrating TypeScript in NextJS
Setting up TypeScript with NextJS is pretty straightforward. NextJS supports TypeScript out-of-the-box, so all you need to do is initialise your NextJS project and create a `tsconfig.json` file in your project root:
```javascript
touch tsconfig.json
```
NextJS will automatically detect this file and install the necessary TypeScript dependencies for you. If you run your server now (`npm run dev`), you'll find that NextJS has populated your `tsconfig.json` with a reasonably basic TypeScript configuration.
This immediate support for TypeScript makes us one step closer to building type-safe applications with NextJS.
Why TypeScript with NextJS?
Before we move to code examples, let's understand why TypeScript is beneficial when paired with NextJS. TypeScript's rigorous typing system reduces runtime errors, making your code much more robust and reliable. It also significantly improves the developer experience with features like autocompletion, type inference, and type checking.
When building applications with NextJS, TypeScript helps manage the complexity with features like Modules, Namespaces, and Decorators. In the following sections, we will be exploring how you can efficiently apply TypeScript in your NextJS applications.
TypeScript in NextJS: Best Practices
Now let's delve into specific examples and best practices for using TypeScript in NextJS.
**1. Type External API Data:** Always type the data you receive from an API to avoid runtime discrepancies. ```typescript
type Post = {
id: string; title: string; content: string; };
export async function getStaticProps() {
const res = await fetch('https://.../posts') const posts: Post[] = await res.json() return { props: { posts } } } ```
In the above example, we explicitly define what a Post object consists of to avoid ambiguity and potential runtime errors.

These guidelines and best practices can help you integrate TypeScript in your Next.js projects effectively. With the successful integration of TypeScript, Next.js apps become a lot more error-resistant and maintainable.
If you want to fast-track this process and jumpstart your web development project, consider using a NextJS boilerplate like [PullTheCode](https://pullthecode.com/). PullTheCode is designed to rapidly build and deploy web applications like SaaS platforms, AI tools, blogs, or other web apps.
PullTheCode streamlines development by providing essential features such as SEO & Blog integration, Stripe payments, SQL with Prisma, SSO with PassportJS, Google Analytics, amongst others. The product is ideal for developers and startups who want to launch their MVPs quickly and efficiently. Additionally, PullTheCode offers weekly updates, and specific modules like the Scraping or Internationalization (coming soon).
