Do I need to utilize getStaticProps along with JSON imports in Next.js?

Is it necessary to use getStaticProps in order to render static data from a JSON or typescript file, or can the data be imported without using getStaticProps? The documentation I read didn't provide a clear answer.

projects.tsx

const projects: [
  {
    id: "6853939";
    name: "Project 01";
    title: "Title 01 ";
    previewImg: "/images/projectThumbnails/image01.jpg";
  },
  {
    id: "6853939";
    name: "Project 02";
    title: "Title 02 ";
    previewImg: "/images/projectThumbnails/image02.jpg";
  }
];

export default projects;

names.json

{
  "names": [
    { "name": "Full Name 01", "age": 34 },
    { "name": "Full Name 02", "age": 22 },
  ],
}

index.tsx

import projects from "../data/projects.tsx";
import names from "../data/names.json";

const IndexPage = () => {
  return (
    <>
      <div>
        {projects.map((i) => (
          <div key={i.id}>{i.title}</div>
        ))}
      </div>
      <div>
        {names.names.map((i) => (
          <div key={i.name}>{i.name}</div>
        ))}
      </div>
    </>
  );
};

Answer №1

It's completely your decision on which method you choose to implement.

Utilizing getStaticProps:

The server utilizes JSON data for injecting data and creating a cache.

Without getStaticProps:

The JSON file will be injected on the client side, without being stored in a cache.

I personally suggest using getStaticProps

Answer №2

Utilizing JSON files within the getStaticProps function:

import jsonData from ('./sample.json')


export async function getStaticProps(context) {
  
  //access and use your JSON data here 
  
  return {
    props: {}, // these properties will be sent to the page component
  }
}
