The Gatsby blog core theme
A Gatsby theme for creating a blog child theme. It includes all of the data structures you need to get up and running building a blog and includes no additional theming or style opinions.
Installation
For a new site
If you're creating a new site and want to use the blog theme, you can use the blog theme starter. This will generate a new site that pre-configures use of the blog theme.
gatsby new my-themed-blog https://github.com/gatsbyjs/gatsby-starter-blog-theme-core
For an existing site
- Install the theme
npm install gatsby-theme-blog-core
- Add the configuration to your
gatsby-config.js
file
module.exports = {
plugins: [
{
resolve: `gatsby-theme-blog-core`,
options: {
basePath: `/blog`,
},
},
],
}
-
Add blog posts to your site by creating md
or mdx
files inside /content/posts
.
Note that if you've changed the default contentPath
in the configuration, you'll want to add your markdown files in the directory specified by that path.
-
Run your site using gatsby develop
and navigate to your blog posts. If you used the above configuration, your URL will be http://localhost:8000/blog
