Convenience function for using Java libraries in Grakkit

README.md

loadClasses - A function to simplify using external library JARs in Grakkit

Turns this:

const SC = {
  Socket: load('./plugins/grakkit/socketcluster-2.0.0.jar', 'io.github.sac.Socket'),
  BasicListener: load('./plugins/grakkit/socketcluster-2.0.0.jar', 'io.github.sac.BasicListener'),
  Emitter: {
    Listener: load('./plugins/grakkit/socketcluster-2.0.0.jar', 'io.github.sac.Emitter$Listener'),
  },
  ReconnectStrategy: load('./plugins/grakkit/socketcluster-2.0.0.jar', 'io.github.sac.ReconnectStrategy'),
}

into this:

const SC = loadClasses('./plugins/grakkit/socketcluster-2.0.0.jar', 'io.github.sac', [
  'Socket',
  'BasicListener',
  'Emitter.Listener',
  'ReconnectStrategy'
])

grakkit-loadClasses.ts

import { load } from '@grakkit/stdlib-paper'
// import { load } from '@grakkit/stdlib-minestom'

export const loadClasses = (jarPath: string, ns: string, classes: Array<string>): Object => {
  let result = {}
  for (const idx in classes) {
    const className = classes[idx]
    const classpath = `${ns}.${className.replaceAll('.','$')}`
    const accu = load(jarPath, classpath)
    const keys = className.split('.')
    for (const key in keys.reverse()) {
      const cache = accu
      accu = {}
      accu[keys[key]] = cache
    }
    result = { ...result, ...accu }
  }
  return result
}
