Moved from Wordpress to Gatsby

09.08.2022 — 3 min read

First post to move from Wordpres to Gatsby. The rest of the content will be added here soon. For now i'll just add some code to keep the examples with me.

Take a while and listen a quality underground hip-hop from Wrocław/Poland:

Here will a live code example go:

const onClick = () => {
  alert("You opened me");
};
render(<button onClick={onClick}>Alohomora!</button>);

Here will a normal code block go:

(function() {

var cache = {};
var form = $('form');
var minified = true;

var dependencies = {};

var treeURL = 'https://api.github.com/repos/PrismJS/prism/git/trees/gh-pages?recursive=1';
var treePromise = new Promise(function(resolve) {
	$u.xhr({
		url: treeURL,
		callback: function(xhr) {
			if (xhr.status < 400) {
				resolve(JSON.parse(xhr.responseText).tree);
			}
		}
	});
});

A code block with a JSDoc comment, short, and long comment:

/**
 * Get value out of string (e.g. rem => px)
 * If value is px strip the px part
 * If the input is already a number only return that value
 * @param {string | number} input
 * @param {number} [rootFontSize]
 * @return {number} Number without last three characters
 * @example removeLastThree('6rem') => 6
 */
const getValue = (input, rootFontSize = 16) => {
  if (typeof input === `number`) {
    return input / rootFontSize;
  }

  const isPxValue = input.slice(-2) === `px`;

  if (isPxValue) {
    return parseFloat(input.slice(0, -2));
  }

  return parseFloat(input.slice(0, -3));
};

// This is a little helper function
const helper = (a, b) => a + b;

// This is also a little helper function but this time with a really long one-line comment that should show some more details
const morehelper = (a, b) => a * b;

export { getValue, helper, morehelper };

Normal block without language:

import Test from "../components/test"

const Layout = ({ children }) => (
  <Test>
    {children}
  </Test>
)

export default Layout

Code block with code highlighting:

import * as React from "react";

const Post = ({ data: { post } }) => (
  <Layout>
    <Heading variant="h2" as="h2">
      {post.title}
    </Heading>
    <p
      sx={{
        color: `secondary`,
        mt: 3,
        a: { color: `secondary` },
        fontSize: [1, 1, 2],
      }}
    >
      <span>{post.date}</span>
      {post.tags && (
        <React.Fragment>
          {` — `}
          <ItemTags tags={post.tags} />
        </React.Fragment>
      )}
    </p>
    <section
      sx={{
        ...CodeStyles,
        my: 5,
        ".gatsby-resp-image-wrapper": { my: 5, boxShadow: `lg` },
      }}
    >
      <MDXRenderer>{post.body}</MDXRenderer>
    </section>
  </Layout>
);

export default Post;

Code block without title:

Harry Potter and the Philosopher's Stone

Code block without lineNumbers (but lang):

Harry Potter and the Chamber of Secrets

Code block without lineNumbers (and without lang):

Harry Potter and the Chamber of Secrets

Code block with only the title:

const scream = (input) => window.alert(input)

Code block with only the title but without lineNumbers:

const scream = (input) => window.alert(input)

Line highlighting without code title:

const test = 3;
const foo = "bar";
const harry = "potter";
const hermione = "granger";
const ron = "weasley";

Here will inline code go, just inside the text. Wow!

Code block without line numbers but with highlighting, language, and title:

import * as React from "react";

const Blog = ({ posts }: PostsProps) => {
  const { tagsPath, basePath } = useSiteMetadata();

  return (
    <Layout>
      <Flex sx={{ alignItems: `center`, justifyContent: `space-between` }}>
        <Heading variant="h2" as="h2">
          Blog
        </Heading>
        <Styled.a
          as={Link}
          sx={{ variant: `links.secondary` }}
          to={`/${basePath}/${tagsPath}`.replace(/\/\/+/g, `/`)}
        >
          View all tags
        </Styled.a>
      </Flex>
      <Listing posts={posts} sx={{ mt: [4, 5] }} />
    </Layout>
  );
};

export default Blog;
