serve-esnext v0.0.2
serve-esnext
Seamlessly run ES.Next code in the browser.
Currently, when starting a new JavaScript web application project, a significant amount of time is spent coordinating different libraries to compile ES.Next into ES5 and load it into the browser. External dependencies have to be declared and configured via configuration files committed to the codebase.
The WHATWG is developing the
JavaScript Loader Standard, which defines
how browsers should handle the import and export keywords.
serve-esnext coordinates and configures the necessary libraries to implement
the JavaScript Loader Standard without requiring additional configuration.
Installing
serve-esnext is available as an
npm package.

In package.json, run serve-esnext as follows:
{
"name": "project",
"private": true,
"scripts": {
"start": "serve-esnext"
}
}serve-esnext assumes the following project directory structure:
package.json
