## What it is
Nanobar is an ultra-lightweight (~699 bytes gzipped) JavaScript library for creating progress bars in the browser, with no jQuery dependency. It renders a fixed or targeted progress bar that you advance with a simple go(percentage) call.

## Use cases
- show a slim loading bar at the top of a page during ajax requests
- add a lightweight progress indicator without jQuery
- display upload or download progress in the browser
- create a minimal progress bar with custom styling
- indicate page transition loading progress

## When to choose
- you need a tiny, dependency-free progress bar for any browser including legacy IE
- you want a simple API (just go(percentage)) with CSS-customizable bars

## When to avoid
- you need rich progress UI like circular indicators, labels, or file-based progress
- you need a library under active development or modern framework integration

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: frontend, web-development
- platform: browser
- tags: progress-bar, minimalist, zero-dependency, vanilla-js, loading-indicator, nodejs
