How do i install the highlight to my gatsby site

12 Jul 2019 - 2 min read - SSG

My website is not a coder based, but why do i think the highlight is important? It's 'cause i take a note from that activity. Besides, i like the artistic view of the code that i wrote to my note.

Here we go

This is the screenshot before i install the highlight.

before

And this is the screenshot after i install the highlight.

after

So, how do i do that?

  1. I found this awesome plugin that called gatsby-remark-prismjs. We need to install plugin to our gatsby site first.
npm install --save gatsby-transformer-remark gatsby-remark-prismjs prismjs
  1. After that, we need to configure it in gatsby-config.js inside the gatsby-transformer-remark.
// gatsby-config.js

plugins: [{
  resolve: `gatsby-transformer-remark`,
  options: {
    plugins: [{
      resolve: `gatsby-remark-prismjs`,
      options: {
        classPrefix: "language-",
        inlineCodeMarker: null,
        aliases: {},
        showLineNumbers: false,
        noInlineHighlight: false,
      },
    }],
  },
}]
  1. I found that we can use default theme under node_modules/prismjs/themes/ and it's look akward IMO. So i start to write my own style based on the prismjs theme. It look like this.
// highligt.scss

  1. Don't forget to import it to gatsby-browser.js
require('./path/to/highlight.scss')
  1. Run the gatsby to test it.
gatsby develop

Cheer...
