Error encountered in NEXT JS: Unable to parse URL from /api/projects or Error message: Failed to connect to 127.0.0.1:3000

Question

Error encountered in NEXT JS: Unable to parse URL from /api/projects or Error message: Failed to connect to 127.0.0.1:3000

Currently utilizing:

export const getStaticProps = async () => {

export const getStaticPaths = async () => {

and accessing my API (pages/api/projects/) created with Next.js on my local host

  const res = await fetch("http://localhost:3000/api/projects");

When deploying the app on Netlify, I encounter an error - connect ECONNREFUSED 127.0.0.1:3000 Attempting to change the URL to "/api/projects/"

  const res = await fetch("/api/projects/");

results in a new error "TypeError: Failed to parse URL from /api/project" indicating that Next.js requires a complete URL to access the data.

The final URL on Netlify is , implying that the API needs to be up and running first. How can I achieve this if deploying the app is required to run the API?

"Netlify expects:"

const res = await fetch("https://v2ds.netlify.app/api/projects/");

But how do I access the API without building the application for the first time? Working with getStaticProps, getStaticPaths, Mongoose, and the Next.js API.

The primary question remaining is how to deploy my app on Netlify while still being able to access the data during build time?

Thank you, Appreciate any assistance.

When it comes to server side operations, everything is housed on the server. This means there's no need to send an http request for a relative url. Instead, you simply import your api file and execute the following code:

 const data = await import("../../../the_path_to_your_api_file");

After importing, you can then access your handler function like so:

await (await data.handler()).json()

I trust this explanation clarifies things!

To customize API requests based on the environment, you can separate the base URL for the API request. For example:

Create a component named "checkEnvironment" to return the appropriate base URL.

export const checkEnvironment = () => {
  let base_url =
    process.env.NODE_ENV === "development"
      ? "http://localhost:3000"
      : "https://example.com"; // https://v2ds.netlify.app

  return base_url;
};

Then utilize this in your getStaticProps like so:

export const getStaticProps = async (ctx: any) => {
    const posts = await fetch(checkEnvironment().concat("/api/posts"));
    const json = await posts.json();
  
    return {
      props: { data: json },
    };
};

Edit- For different local and production environments, you can implement something similar to this:


export const getServerSideProps = async (ctx: NextPageContext) => {
  const request = await fetch(
    process.env.NODE_ENV === "development"
      ? `http://${ctx.req?.headers.host}/api/products`
      : `https://${ctx.req?.headers.host}/api/products`
  );
  const json = await request.json();

  return {
    props: {
      data: json.data,
    },
  };
};

If you want to make sure your app runs smoothly, start by deploying just the API without any pages. This way, when your app requires data during build time, it can easily access the public link. Once that's done, you can proceed to build the rest of the app and everything should work seamlessly!
