Teach me how to utilize Import / require() in Static Folder

I've been attempting this task for a while, but I'm unsure how to incorporate import or require into the express static folder. When I try to use it, I receive an error stating "require not defined" which makes sense since these are not supported in browsers. I don't want to spend time setting up webpack, babel, or browserify, so is there another method to achieve this quickly and easily?

Answer №1

Using require in a browser is not possible because CommonJS is designed to handle modules in non-browser environments.

To manage modules in the browser, you should follow the ECMAScript modules standard.

To use the import and export keywords in JavaScript files, simply add the type="module" attribute to your script tags.

With ECMAScript modules, you can manage modules natively without needing a build process for front-end JavaScript code.

If you need to import third-party libraries, you can:

  • Include them in your static folder (packaged as either ECMAScript module or UMD) and add corresponding script tags
  • Reference them from a CDN (packaged as either ECMAScript module or UMD) using script tags
  • Use a build process to bundle, treeshake, and minify the entire codebase, including libraries from node_modules

For example, here is a library available as an ECMAScript module and UMD on a CDN:
