Question 1

How do I draw a line with node-drawille?

Accepted Answer

Since node-drawille only has basic point methods, you need to use an external library like bresenham. Install bresenham via npm and integrate it to calculate and set points along a line on the canvas.

Question 2

node-drawille vs asciimoo/drawille, which should I use?

Accepted Answer

node-drawille is a Node.js port of asciimoo/drawille, designed for JavaScript environments. If you're building a Node.js application, node-drawille is the better choice due to npm integration and compatibility with modules like drawille-canvas.

Question 3

Can I animate graphics in the terminal using node-drawille?

Accepted Answer

Yes, by clearing and redrawing the canvas in a loop, similar to the cube.gif example. However, performance depends on terminal refresh rates and drawing complexity, so test for smoothness in your setup.

Question 4

What terminals support Braille characters for node-drawille?

Accepted Answer

Most modern terminals with Unicode support, like iTerm2 or GNOME Terminal, should work. However, compatibility can vary—check your terminal's Braille rendering to avoid issues in production.

Question 5

How to use drawille-canvas with node-drawille?

Accepted Answer

Install drawille-canvas separately via npm; it provides a higher-level Canvas API on top of node-drawille. Use it for complex drawings without manual point manipulation, as noted in the README's projects section.

Question 6

Is node-drawille good for real-time data visualization?

Accepted Answer

It's used in tools like vtop for real-time charts, but for high-frequency updates, be mindful of terminal performance limits. Optimize by reducing canvas size or update frequency to avoid lag.
