reactty

have YOU ever wanted to make a cli app that looks and feels kinda maybe like a desktop or webapp? is ncurses too rich for your blood? have you had to settle for spamming console.logs like a peasant? have I got a thing for YOU!

introducing (for the first time ever) reactive mustache-like templating for TTY!!!

just follow the steps:

1. create a template (any mustache template will do, i'm using handlebars under the hood)
2. create a view with that template
3. just update the context object and...
4. voilà, shit just rendered the change itself!

usage

npm install --save reactty

for now, check out ./test/basic.js for features

things to note:

• if the output is too big, scroll around with the arrow keys (issue #2) or the mouse wheel (issue #12). if excess data exists above or below, indicator arrows will appear (issue #4)
• the display seen when resizing the window is a little bit broken (due to how node triggers its resize event, it will always be one step late)
• templates now support color and styles. the (tentative) syntax is available in test/styles-template.hbs (issue #8)
• display will only re-render if its contents have changed (issue #10)
• on a safe (code 0) exit from the program, the full output, as defined in the template, will be printed for easy copy/paste of the output (issue #6)
