Get started

This repo contains the code for https://devii.dev.

devii.dev serves as both the documentation AND a working demo of Devii. After you clone/fork it, you can look through the code to learn how Devii works. Then you can rip out everything you don't like, customize everything else, and build your own tools and components on top of the foundation Devii provides!

Your personal website is the online manifestation of you. Devii doesn't really provide much out of the box. It provides some nice Medium-style default styles for your blog posts and some tools for loading/rendering Markdown. But you'll have to implement your own homepage more or less from scratch. And that's the point! Don't settle for some theme. Build something that represents you.

To get started:

  1. Fork this repo
  2. git clone git@github.com:yourusername/devii.git my-blog
    cd my-blog
    yarn
    
  3. Start the development server with yarn dev. This should start a server on http://localhost:3000.

Powered by Next.js

The core of this repo is Next.js. We chose Next.js because it's the simplest, most elegant way to generate a static version of a React-based website. The documentation is excellent; read it first: Next.js Documentation.

Project structure

Here's is an abbreviated version of the project structure. Certain config files (next.config.js, next-end.d.ts, .gitignore) have been removed for simplicity.

.
├── README.md
├── public // all static assets (images, css, etc) go here
├── pages // every .tsx component in this dir becomes a page of the final site
|   ├── index.tsx // the home page (which has access to the list of all blog posts)
|   ├── blog
|       ├── [blog].md // a template component that renders the blog posts under `/md/blog`
├── md
|   ├── blog
|       ├── devii.md // this page!
        ├── whatever.md // every MD file in this directory becomes a blog post
├── components
|   ├── BlogPost.tsx
|   ├── Code.tsx
|   ├── Footer.tsx
|   ├── Header.tsx

|   ├── Meta.tsx
|   ├── <various>
├── loader.ts // contains utility functions for loading/parsing Markdown
├── node_modules
├── tsconfig.json
├── package.json

Next.js generates a new webpage for each file in the pages directory. If you want to add an About page to your blog, just add about.tsx inside pages and start writing the page.

By default the repo only contains two pages: a home page (/pages/index.tsx) and a blog page (/pages/[blog].md).

The file [blog].ts follows the Next.js convention of using square brackets to indicate a dynamic route.

The home page

The home page is intentionally minimal. You can put whatever you want in index.tsx; one of our goals in designing Devii was to place no restrictions on the developer. Use your imagination! Your website is the online manifestion of you. You can use whatever npm packages or styling libraries you like.

Styling

Devii is unopinionated about styling. Because your Devii site is a standard React app under the hood, you can use your favorite library from npm to do styling.

Devii provides certain styles by default, notably in the Markdown renderer (/components/Markdown.tsx). Those styles are implemented using Next's built-in styling solution styled-jsx. Unfortunately it was necessary to make those styles global, since styled-jsx doesn't play nice with third-party components (in this case react-markdown).

Feel free to re-implemement the built-in styles with your library of choice If you choose to use a separate styling library (emotion is pretty glorious) then you could re-implement the default styles

Adding a new blog post

Just add a Markdown file under md/blog/ to create a new blog post:

  1. Create a new Markdown file called foo.md within the /md/blog directory
  2. Add in some basic Markdown content
  3. Then go to http://localhost:3000/blog/foo. You should see the new post.

Frontmatter support

Every Markdown file can include a "frontmatter block" containing various metadata. Devii provides a loadPost utility that loads a Markdown file, parses it's frontmatter metadata, and returns a structured PostData object:

type PostData = {
  path: string;
  title?: string;
  subtitle?: string;
  description?: string; // used for SEO
  canonicalUrl?: string; // used for SEO
  datePublished?: number; // Unix timestamp
  author?: string;
  authorPhoto?: string;
  authorHandle?: string; // twitter handle
  tags?: string[];
  bannerPhoto?: string;
  thumbnailPhoto?: string;
};

For example, here is the frontmatter blog from the sample blog post (md/blog/the-ultimate-tech-stack.md):

View /loader.ts to see how this works.

Google Analytics

Just add your Google Analytics ID (e.g. 'UA-999999999-1') to globals.ts and Devii will automatically add the appropriate Google Analytics snippet to your site. Go to /pages/_app.ts to see how this works or customize this behavior.

Medium-inspired design

The Markdown renderer (Markdown.tsx) provides a default style inspired by Medium. Just modify the CSS in Markdown.tsx to customize the design to your liking.

GitHub-style code blocks

You can easily drop code blocks into your blog posts using triple-backtick syntax (just like GitHub). No more embedding CodePen iframes! 🚀

Works out-of-the-box for all programming languages. Specify your language with a "language tag". So this:

<pre> ```ts // pretty neat huh? const test = (arg: string) => { return arg.length > 5; }; ```</pre>

turns into

// pretty neat huh?
const test = (arg: string) => {
  return arg.length > 5;
};

View /components/Code.tsx to see how this works or customize this behavior.

Markdown loading

You don't need to understand all of this to use Devii. Consider this an "advanced guide" you can use if you want to customize the structure of the site.

Markdown posts are loaded during Next.js static build step. Check out the Data Fetching documentation to learn more about this.

Here's the short version: if export a function called getStaticProps from one of your page components, Next.js will execute that function, take the result, and pass the props property (which should be another object) into your page as props.

You can dynamically load and parse a Markdown file using loadMarkdownFile, a utility function implemented in loader.ts. It is an async function that returns a PostData TypeScript object containing all the metadata keys listed above:

For an example of this, check out the getStaticProps implementation from the homepage. The function calls loadBlogPosts - a utilty function that loads every blog posts in the /md/blog/ directory, parses them, and returns PostData[].

export const getStaticProps = async () => {
  const posts = await loadBlogPosts();
  return { props: { posts } };
};

There are a few utility functions in loader.ts that Devii uses. All functions are async! All functions accept a relative path which is expected to be _relative to the md/ directory. For instance loadPost('blog/test.md') would load /md/blog/test.md.

Static generation

You can generate a fully static version of your site using yarn build && yarn export. This step is entirely powered by Next.js. The static site is exported to the out directory.

After it's generated, use your static file hosting service of choice (Vercel, Netlify, Firebase Hosting, Amazon S3) to deploy your site.

Global configs

There is a globals.ts file in the project root containing some settings/configuration metadata about your site:

RSS feed generation

An RSS feed is auto-generated from your blog post feed. This feed is generated using the rss module (for converting JSON to RSS format) and showdown for converting the markdown files to RSS-compatible HTML.

For RSS generation to work, all your posts must contain a datePublished timestamp in their frontmatter metadata. To examine or customize the RSS generation, check out the rssUtil.ts file in the root directory.

SEO

Every blog post page automatically populated meta tags based on the post metadata. This includes a title tag, meta tags, og: tags, Twitter metadata, and a link tag containing the canonical URL.

The default value of the canonical URL is computed by concatenating the value of your url config (see Global Configs above) and the relative path of your post. Verify that the canonical URL is exactly equivalent to the URL in the browser when visiting your live site, otherwise your site's SEO may suffer.

Insanely customizable

There's nothing "under the hood" here. You can view and modify all the files that provide the functionality listed above. Devii just provides a project scaffold, some Markdown-loading loading utilities (in loader.ts), and some sensible styling defaults (especially in Markdown.tsx).

To get started customizing, check out the source code of index.tsx (the home page), BlogPost.tsx (the blog post template), and Markdown.tsx (the Markdown renderer).
