Bundler
Noun · Development
Definitions
A tool that combines multiple source files (and their dependencies) into one or more optimized output files for deployment — in JavaScript, tools like Webpack, Rollup, esbuild, and Vite; in Ruby, the gem dependency manager.
In plain English: A tool that takes all your project's code files and smashes them together into fewer, optimized files ready to ship to users.
Example: "Switching from Webpack to esbuild as our bundler dropped the build from 45 seconds to under 1."
