It then rapidly evolved into a **never-ending rabbithole** which ended up with support for themes (i.e railscast, darcula, monokai, etc), customizable styles, and copy functionality too! I don't plan on keeping this updated unless people are looking to actually use it. So don't be shy! Feel free to post an [issue](https://help.github.com/en/github/managing-your-work-on-github/creating-an-issue) or a [pr](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request). ### ✨ [Demo](https://react-code-blocks.netlify.com/) [![Netlify Status](https://api.netlify.com/api/v1/badges/a2a9f006-efd5-476f-ade6-11cde1ddc11e/deploy-status)](https://app.netlify.com/sites/react-code-blocks/deploys) [![Check out react-code-blocks](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/react-code-blocks-xgjrr?fontsize=14) ## Install Install `react-code-blocks` via `yarn` or `npm` ```sh yarn add react-code-blocks ``` ```sh npm i react-code-blocks ``` ## Usage > Updated usage instructions can be found [here](https://react-code-blocks.rajinwonderland.vercel.app/) ```js import { CopyBlock } from 'react-code-blocks'; ``` ```js function MyCodeComponent(props) { return ( <CopyBlock text={props.code} language={props.language} showLineNumbers={props.showLineNumbers} wrapLines /> ); } ``` ## Components ### CodeBlock A simple code block component ```js import { CodeBlock, dracula } from 'react-code-blocks'; function MyCoolCodeBlock({ code, language, showLineNumbers }) { return ( <CodeBlock text={code} language={language} showLineNumbers={showLineNumbers} theme={dracula} /> ); } ``` #### Props > Note that `CodeBlock` & `CopyBlock` share exactly the same props | name | type | default | description | | ----------------- | --------- | ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `text` | `string` | **required** | The code to be formatted | | `language` | `string` | "text" | The language in which the code is written. [See here](LANGUAGES.md) for a list of supported languages | | `showLineNumbers` | `boolean` | `true` | Indicates whether or not to show line numbers | | `theme` | `object` | **dracula** | A theme object for the code block. [See here](THEMES.md) for a list of supported themes | | | `highlight` | `string` | "" | Lines to highlight! For multiple lines, use a comma i.e `highlight="1,6,7"`. For a range of lines, use a `-` i.e `highlight="1-5"` for highlighting lines 1-5. | --- > **more to come...** ### CopyBlock A code block component with a little copy button for copying a snippet. ```jsx import { CopyBlock, dracula } from 'react-code-blocks'; function MyCoolCodeBlock({ code, language, showLineNumbers }) { <CopyBlock text={code} language={language} showLineNumbers={showLineNumbers} theme={dracula} codeBlock />; } ``` #### Props Same as the `CodeBlock`'s component with the exception of one! | name | type | default | description | | ----------- | ---------- | ------- | --------------------------------------------------------------------------------------------------------------------------------- | | `codeBlock` | `boolean` | `false` | Indicates whether to render the `CopyBlock` as an inline `Code` component or a `CodeBlock` component | | `onCopy` | `function` | - | The onCopy function is called if the copy icon is clicked. This enables you to add a custom message that the code block is copied | ## Supported Themes For a list of supported themes, check out the [list here](THEMES.md) ## Supported Languages For a list of supported languages, check out the [list here](LANGUAGES.md) ## Alternatives If you're looking for some more maintained solutions, I'd suggest the following: - [`react-syntax-highlighter`](https://github.com/conorhastings/react-syntax-highlighter): syntax highlighting component for react with `prismjs` or `highlightjs` `ast` using inline styles by @conorhastings. - It's actually used in this project as well! :smile: - [`react-highlight.js`](https://github.com/bvaughn/react-highlight.js): A lightweight React wrapper around the `Highlight.js` syntax highlighting library by @bvaughn. - [`react-live`](https://github.com/FormidableLabs/react-live): A flexible playground for live editing React components by @FormidableLabs. - [`@atlaskit/code`](https://atlaskit.atlassian.com/docs/getting-started): Renders inline code snippets and code blocks - Original inspiration for this project kit for this project - [`carbon-components-react`](http://react.carbondesignsystem.com/?path=/story/codesnippet--inline): Check out their `<CodeSnippet>` component which supports multi-line, single-line, and inline snippets along with added copying functionality. > Feel free to add any other alternative packages here! :smile: ## Todos - [x] Add a better readme - [x] Highlighting line feature - [x] Supported Themes documentation - [x] Supported Languages documentation - [x] Add a License - [ ] Docs for usage with GatsbyJS - [ ] Docs for usage with `MDX` - [ ] Contributor guide for development - [ ] Contributor guide for adding themes - [ ] Contributor guide for adding languages - [ ] Document props for `Code` component - [ ] Better demo - [x] Storybook with Docs - [x] Move to typescript - [ ] A component with a terminal around it. because why not!?
