# react-blessed A [React](https://facebook.github.io/react/) custom renderer for the [blessed](https://github.com/chjj/blessed) library. This renderer should currently be considered as experimental, is subject to change and will only work with React's latest version (`17.x.x`, using Fiber). ![demo](https://raw.githubusercontent.com/Yomguithereal/react-blessed/master/img/demo.gif) ## Summary * [Installation](#installation) * [Demo](#demo) * [Usage](#usage) * [Rendering a basic application](#rendering-a-basic-application) * [Nodes & text nodes](#nodes--text-nodes) * [Refs](#refs) * [Events](#events) * [Classes](#classes) * [Using blessed forks](#using-blessed-forks) * [Using the devtools](#using-the-devtools) * [Roadmap](#roadmap) * [FAQ](#faq) * [Contribution](#contribution) * [License](#license) ## Installation You can install `react-blessed` through npm: ```bash # Be sure to install react>=17.0.0 & blessed>=0.1.81 before npm install blessed react # Then just install `react-blessed` npm install react-blessed ``` ## Demo For a quick demo of what you could achieve with such a renderer you can clone this repository and check some of the [examples](./examples): ```bash git clone https://github.com/Yomguithereal/react-blessed cd react-blessed npm install # To see which examples you can run: npm run demo # Then choose one to run: npm run demo animation ``` ## Usage ### Rendering a basic application ```jsx import React, {Component} from 'react'; import blessed from 'blessed'; import {render} from 'react-blessed'; // Rendering a simple centered box class App extends Component { render() { return ( Hello World! ); } } // Creating our screen const screen = blessed.screen({ autoPadding: true, smartCSR: true, title: 'react-blessed hello world' }); // Adding a way to quit the program screen.key(['escape', 'q', 'C-c'], function(ch, key) { return process.exit(0); }); // Rendering the React app using our screen const component = render(, screen); ``` ### Nodes & text nodes Any of the blessed [widgets](https://github.com/chjj/blessed#widgets) can be rendered through `react-blessed` by using a lowercased tag title. Text nodes, on the other hand, will be rendered by applying the `setContent` method with the given text on the parent node. ### Refs As with React's DOM renderer, `react-blessed` lets you handle the original blessed nodes, if you ever need them, through refs. ```jsx class CustomList extends Component { componentDidMount() { // Focus on the first box this.refs.first.focus(); } render() { return ( First box. Second box. ); } } ``` ### Events Any blessed node event can be caught through a `on`-prefixed listener: ```jsx class Completion extends Component { constructor(props) { super(props); this.state = {progress: 0, color: 'blue'}; const interval = setInterval(() => { if (this.state.progress >= 100) return clearInterval(interval); this.setState({progress: this.state.progress + 1}); }, 50); } render() { const {progress} = this.state, label = `Progress - ${progress}%`; // See the `onComplete` prop return this.setState({color: 'green'})} filled={progress} style={{bar: {bg: this.state.color}}} />; } } ``` ### Classes For convenience, `react-blessed` lets you handle classes looking like what [react-native](https://facebook.github.io/react-native/docs/style.html#content) proposes. Just pass object or an array of objects as the class of your components likewise: ```jsx // Let's say we want all our elements to have a fancy blue border const stylesheet = { bordered: { border: { type: 'line' }, style: { border: { fg: 'blue' } } } }; class App extends Component { render() { return ( First box. Second box. ); } } ``` You can of course combine classes (note that the given array of classes will be compacted): ```jsx // Let's say we want all our elements to have a fancy blue border const stylesheet = { bordered: { border: { type: 'line' }, style: { border: { fg: 'blue' } } }, magentaBackground: { style: { bg: 'magenta' } } }; class App extends Component { render() { // If this flag is false, then the class won't apply to the second box const backgroundForSecondBox = this.props.backgroundForSecondBox; return ( First box. Second box. ); } } ``` ### Using blessed forks Because [blessed](https://github.com/chjj/blessed) is not actively maintained in quite a while, you might want to use one of it's forks. To do that, import `createBlessedRenderer` function instead: ``` import React, {Component} from 'react'; import blessed from 'neo-blessed'; import {createBlessedRenderer} from 'react-blessed'; const render = createBlessedRenderer(blessed); ``` ### Using the devtools `react-blessed` can be used along with React's own devtools for convenience. To do so, just install [`react-devtools`](https://www.npmjs.com/package/react-devtools) in your project and all should work out of the box when running the Electron app, as soon as a `react-blessed` program is running on one of your shells. ## Roadmap * Full support (meaning every tags and options should be handled by the renderer). * `react-blessed-contrib` to add some sugar over the [blessed-contrib](https://github.com/yaronn/blessed-contrib) library (probably through full-fledged components). ## Faq * `` : To enable interactions, add `mouse={ true }` and/or `keys={ true }` ## Contribution Contributions are obviously welcome. Be sure to add unit tests if relevant and pass them all before submitting your pull request. ```bash # Installing the dev environment git clone git@github.com:Yomguithereal/react-blessed.git cd react-blessed npm install # Running the tests npm test ``` ## License MIT
