There are four ways of using this package:
If using es6 modules, just use
import * from 'http-constants/src/main/consts.js'and you should be fine. As with any es6 module usage, you can get as fine-grained with that as you'd like.
If not using es6, the regular node/es5 syntax should work, though you'll need to reference the transpiled file:
var http_const = require('http-constants/target/dist/consts.js');, though this is referenced in the package, so
var http_const = require('http-constants')should do.
Exactly like option #2, but using the minified version.
Something else involving file copying and/or a build pipeline.
Just submit a pull request and I'll get right on integrating it.
