Pros of blessed

• More mature and established project with a larger community
• Offers a wider range of terminal UI components and features
• Provides lower-level control over terminal rendering

Cons of blessed

• Steeper learning curve for developers new to terminal UI development
• Less intuitive for developers familiar with React's component-based approach
• Requires more boilerplate code for complex UI structures

Code Comparison

blessed:

const blessed = require('blessed');
const screen = blessed.screen();
const box = blessed.box({
  content: 'Hello, world!'
});
screen.append(box);
screen.render();

react-blessed:

import React from 'react';
import blessed from 'blessed';
import {render} from 'react-blessed';

const App = () => <box content="Hello, world!" />;
const screen = blessed.screen();
render(<App />, screen);

Summary

blessed is a powerful and flexible library for creating terminal user interfaces, offering more control and a wider range of features. However, it can be more challenging to learn and use effectively. react-blessed, on the other hand, provides a more familiar React-based approach, making it easier for React developers to create terminal UIs, but with potentially fewer advanced features and less direct control over rendering.

Pros of ink

• More actively maintained with frequent updates
• Built-in support for testing and a rich ecosystem of components
• Better TypeScript support and type definitions

Cons of ink

• Steeper learning curve for developers new to React
• May be overkill for simpler CLI applications
• Slightly larger bundle size due to additional features

Code Comparison

ink:

import React from 'react';
import {render, Text} from 'ink';

const App = () => <Text>Hello, world!</Text>;

render(<App />);

react-blessed:

import React from 'react';
import blessed from 'blessed';
import {render} from 'react-blessed';

const App = () => <box>Hello, world!</box>;

const screen = blessed.screen();
render(<App />, screen);

Both libraries allow you to create CLI applications using React, but ink provides a more modern and feature-rich environment. react-blessed offers a simpler approach and may be easier for developers already familiar with the blessed library. ink's ecosystem and active development make it a strong choice for complex CLI tools, while react-blessed might be preferable for quick, simple projects or those with existing blessed code.

Pros of blessed-contrib

• Offers a wide range of pre-built widgets and charts for terminal dashboards
• Provides a more comprehensive set of visualization options out-of-the-box
• Has a larger community and more extensive documentation

Cons of blessed-contrib

• Less flexible for custom component creation compared to React-based alternatives
• May have a steeper learning curve for developers not familiar with the blessed library
• Limited to terminal-based applications, while React-blessed can be used in other contexts

Code Comparison

blessed-contrib:

var blessed = require('blessed');
var contrib = require('blessed-contrib');
var screen = blessed.screen();
var grid = new contrib.grid({rows: 2, cols: 2, screen: screen});
grid.set(0, 0, contrib.line, {label: 'Line Chart'});

react-blessed:

import React from 'react';
import blessed from 'blessed';
import {render} from 'react-blessed';

const App = () => <box>Hello, world!</box>;
render(<App />, screen);

The blessed-contrib example demonstrates the creation of a grid layout with a line chart, showcasing its built-in components. The react-blessed example illustrates a simpler React-style component rendering approach, which may be more familiar to React developers but requires additional setup for complex visualizations.

Pros of termui

• Written in Go, offering better performance for terminal-based UIs
• Provides a wide range of pre-built components and widgets
• Supports real-time updates and animations

Cons of termui

• Less familiar syntax for web developers compared to React
• Limited flexibility in customizing component behavior
• Smaller community and ecosystem compared to React-based solutions

Code Comparison

termui:

ui := termui.New()
p := widgets.NewParagraph()
p.Text = "Hello World!"
ui.Render(p)

react-blessed:

const App = () => (
  <box>
    <text content="Hello World!" />
  </box>
);
render(<App />, screen);

Summary

termui is a powerful Go-based library for creating terminal user interfaces, offering high performance and a rich set of pre-built components. It excels in scenarios where performance is critical and Go is the preferred language. However, it may have a steeper learning curve for web developers accustomed to React.

react-blessed, on the other hand, leverages the familiar React ecosystem, making it easier for web developers to create terminal UIs using JSX syntax. It offers greater flexibility in component customization but may not match the raw performance of termui for complex interfaces.

The choice between the two depends on the developer's familiarity with Go or React, the project's performance requirements, and the desired level of customization and community support.

Pros of gocui

• Written in Go, offering better performance and lower resource usage
• Provides a more low-level API, allowing for greater customization
• Suitable for creating terminal-based user interfaces without web technologies

Cons of gocui

• Steeper learning curve compared to React-based solutions
• Less extensive ecosystem and community support
• Limited to terminal-based applications, lacking cross-platform GUI capabilities

Code Comparison

gocui example:

g, err := gocui.NewGui(gocui.OutputNormal)
if err != nil {
    log.Panicln(err)
}
defer g.Close()

react-blessed example:

import blessed from 'blessed';
import {render} from 'react-blessed';

const screen = blessed.screen();
render(<App />, screen);

The gocui example demonstrates the initialization of a new GUI, while the react-blessed example shows how to render a React component to a blessed screen. gocui requires more setup but offers finer control, whereas react-blessed provides a familiar React-like syntax for creating terminal UIs.

Pros of tview

• Written in Go, offering better performance and lower resource usage
• More comprehensive set of widgets and layout options
• Active development with frequent updates and bug fixes

Cons of tview

• Steeper learning curve for developers not familiar with Go
• Less flexibility in customizing UI components compared to React-based solutions
• Smaller community and ecosystem compared to React

Code Comparison

react-blessed:

import blessed from 'blessed';
import { render } from 'react-blessed';

const App = () => (
  <box label="Hello world!" border={{ type: 'line' }}>
    <text content="Press q to exit" />
  </box>
);

const screen = blessed.screen();
render(<App />, screen);

tview:

package main

import (
    "github.com/rivo/tview"
)

func main() {
    box := tview.NewBox().SetBorder(true).SetTitle("Hello, world!")
    if err := tview.NewApplication().SetRoot(box, true).Run(); err != nil {
        panic(err)
    }
}

Both libraries provide ways to create terminal-based user interfaces, but they differ in their approach and target audience. react-blessed leverages the React ecosystem and JSX syntax, making it familiar to web developers. tview, on the other hand, offers a native Go experience with potentially better performance and a richer set of built-in widgets. The choice between the two depends on the developer's preferred language, performance requirements, and desired level of customization.
