FAQs
What is esbuild?
esbuild is an extremely fast JavaScript bundler and minifier. It bundles your modules, transpiles modern syntax and can minify the result in milliseconds.
How do I run the generated script?
Save the output as build.js, run npm install esbuild in your project, then run node build.js. The bundle will be written to your chosen output file.
What is the difference between IIFE, CommonJS and ESM?
IIFE wraps your code for direct use in browsers, CommonJS is the classic Node.js module format, and ESM is the modern standard used by browsers and newer Node.js projects.
Do I need an account to use this tool?
No. Like every tool on ToolsFreeHub, the esbuild Config Generator is free and works without signing up.
