## What it is
Mancy is a cross-platform NodeJS REPL desktop application built on Electron and React. It provides a rich interactive JavaScript console with syntax highlighting, auto-completion, multiple language modes (TypeScript, CoffeeScript, LiveScript, ClojureScript), and data visualization of REPL outputs.

## Use cases
- run a graphical node repl with syntax highlighting
- experiment with typescript or coffeescript interactively
- inspect buffers regexes and html output in a repl
- save and reload node session history
- try async await snippets with auto async wrapping

## When to avoid
- you need a maintained tool - the last release was 2019 and the project appears inactive
- you only need a lightweight terminal REPL
- you need REPL support for languages beyond the five supported ones

## Facets
- artifact type: application
- maturity: abandoned
- function: interpreter, developer-tools, terminal-ui, data-visualization
- domain: developer-tools
- platform: cross-platform, windows
- tags: repl, nodejs, electron, read-eval-print-loop, typescript, coffeescript, livescript, clojurescript, syntax-highlighting, command-line, javascript, desktop, macos, linux
