Creating a new blog post in gatsby

Here's a step-by-step guide on how to create a new blog post in Gatsby:

Prerequisites

You have a Gatsby project set up on your local machine.
You have installed the gatsby command-line interface (CLI) globally on your machine.
You have a basic understanding of Gatsby and its file structure.

Step 1: Create a new blog post file

In your Gatsby project, navigate to the src/pages directory and create a new file with a name that follows the convention blog-post-<slug>.mdx. For example, blog-post-my-new-blog-post.mdx.

Step 2: Write your blog post content

In the new file, write your blog post content in Markdown format. You can use Markdown syntax to format your text, add headings, links, images, and more.

Here's an example of what your blog post file might look like:

---
title: My New Blog Post
date: 2023-02-20T14:30:00.000Z
slug: my-new-blog-post
---

This is my new blog post. It's a great day to write about something new!

Step 3: Add metadata

In the front matter of your blog post file, add metadata such as the title, date, and slug. The metadata will be used to generate the blog post's URL and metadata.

Step 4: Create a new blog post component

In your Gatsby project, create a new file in the src/components directory called BlogPost.js. This file will contain the React component that will render your blog post.

Here's an example of what your BlogPost.js file might look like:

import React from 'react';
import { MDXRenderer } from 'gatsby-plugin-mdx';

const BlogPost = ({ data }) => {
  const { frontmatter, html } = data.mdx;
  return (
    <div>
      <h1>{frontmatter.title}</h1>
      <MDXRenderer>{html}</MDXRenderer>
    </div>
  );
};

export const query = graphql`
  query BlogPostQuery($slug: String!) {
    mdx(fields: { slug: { eq: $slug } }) {
      frontmatter {
        title
      }
      html
    }
  }
`;

export default BlogPost;

Step 5: Add the blog post to your Gatsby site

In your gatsby-config.js file, add a new entry to the routes array that points to your new blog post component.

Here's an example of what your gatsby-config.js file might look like:

module.exports = {
  //... other configurations...
  routes: [
    {
      path: '/blog/:slug',
      component: './components/BlogPost',
    },
  ],
};

Step 6: Run Gatsby to build and start your site

Run the following command in your terminal to build and start your Gatsby site:

gatsby develop

Your blog post should now be available at http://localhost:8000/blog/my-new-blog-post.
