How to use:

Let's say

• My posts are under [PROJECT_FOLDER]/content/blogs
• My post template locates at [PROJECT_FOLDER]/src/templates/blog-post.js:

PROJECT_FOLDER
├── src
│   ├── templates
│       ├── blog-post.js
...
├── content
    └── blogs
        └── first-blog
            ├── index.mdx
            ├── index.de.mdx
            ├── index.ja.mdx
            ...

In gatsby-config.js:

plugins: [
  ...
  {
    resolve: '@nathanpate/gatsby-plugin-i18n',
    options: {        
      langKeyDefault: 'en',
      useLangKeyLayout: false,
      pagesPaths: ['/content/blogs/'],
      mdx: {
        postPage: 'src/templates/blog-post.js',
        query: `
        {
          allMdx {
            nodes {
              fields {
                langKey
                slug
              }
              internal {
                contentFilePath
              }
            }
          }
        }
        `
      }
    }
  },
  ...
]

In blog-post.js:

...
export const pageQuery = graphql`
  query BlogPostBySlug($slug: String!) {
    mdx(fields: { slug: { eq: $slug } }) {
      id
      excerpt(pruneLength: 160)
      frontmatter {
        title
        date(formatString: "MMMM DD, YYYY")
      }
    }
  }
`;

The following content is from original repo's README.md:

Hi Folks!

Are you trying to build a multi language gatsby website?

We want to help you! Please open an issue for help, suggestions or bugs.

You can use this plugin with react-intl, i18next, or any other i18n library. This plugin do not translate messages, it just creates routes for each language, and you can use different layouts for each language if you want to.

How it works

Name your files with .langKey.js and the url will be /langKey/path/fileName

Examples:

file	url
src/pages/about.en.js	/en/about
src/pages/about/index.en.js	/en/about
src/pages/blog/gatsby-i18n.pt.md	/pt/blog/gatsby-i18n

Why?

Google! Google needs different URLs to crawl and render your pages for each language.

plugins: [
  {
      resolve: 'gatsby-plugin-i18n',
      options: {        
        langKeyDefault: 'en',
        useLangKeyLayout: false
      }
    }
]

Blog using markdownRemark configuration example:

// Add to gatsby-config.js
plugins: [
  {
      resolve: 'gatsby-plugin-i18n',
      options: {        
        langKeyDefault: 'en',
        useLangKeyLayout: false,
        markdownRemark: {
          postPage: 'src/templates/blog-post.js',
          query: `
          {
              allMarkdownRemark {
                  edges {
                  node {
                      fields {
                      slug,
                      langKey
                      }
                  }
                  }
              }
          }
          `
        }
      }
    }
]

All Options

• langKeyDefault: lanKey to use when no lanKey specified.

• useLangKeyLayout:

  true: use a different layout for each langKey (src/layouts/en.js, src/layouts/pt.js, ...)

  false: use default layout (src/layouts/index.js)

• markdownRemark:

  Add markdownRemark if you are using gatsby-transformer-remark.

  You can set a postPage component and a query to get the pages.

• langKeyForNull: lanKey added to page context and graphql when no langKey specified. Default: any.

• pagesPaths: If you are not using just /src/pages/ folder, you can add an array with the folders your are using:

   plugins:{
     //... other plugins
     resolve: 'gatsby-plugin-i18n',
       options: {        
         //.. other options
         pagesPaths: [ '/my/custom/pages/folder1', /my/custom/pages/folder2/ ]
   }
  

• prefixDefault:

  true: add langKey on all pages, including default

  false: omit langKey in url when page lang is the default. Ex: when langKeyDefault is en, blog/first-post.en.md and blog/first-post.pt.md will have the following urls:

  • /blog/first-post
  • /pt/blog/first-post

  Default: true

Finally
