Include external blog post in the list of posts?

[gaborcsardi]

I sometimes write blog posts other blogs, and would like to include links to these in the list of posts on my personal site. Is there a way to do this in hexo?

I think it's possible by merging the list of articles posted with Hexo and those posted on other sites before displaying them. In the example below, the Hexo API is used directly, but I believe you can achieve the same by incorporating similar code into the theme’s article list page.

// index.js 
const Hexo = require("hexo");
const hexo = new Hexo(process.cwd(), { silent: false });

// In this example, the information about articles posted on other sites is hardcoded, but it's also possible to fetch it via an API.
const otherSiteContents = [{
    title: 'other site A content1',
    updated: new Date(),
    permalink: 'https://site.a.example.com/content1'
  },
  {
    title: 'other site A content2',
    updated: new Date(),
    permalink: 'https://site.a.example.com/content2'
  },
  {
    title: 'other site B content1',
    updated: new Date(),
    permalink: 'https://site.b.example.com/content1'
  }
]

hexo.init().then(() => {
  hexo.load().then(() => {
    const posts = hexo.locals.get("posts");

    const merged = [...posts.toArray(), ...otherSiteContents].sort((a, b) => {
      // Of course, you can also sort by date to get the publication date, or by title to sort by title.
      return new Date(a.updated) - new Date(b.updated);
    });
    for (let post of merged) {
      console.log(`${post.updated} - ${post.title} ${post.permalink}`)
    }
  });
});

If you save the above code as index.js and run it, you'll get the following result.

$ node .\index.js
