A simple save data module for my Node.js projects.

'use-strict';

const path = require('path');

class SaveDataCollection {
  constructor(dataPath, savePath) {
    this.dataPath = path.resolve(dataPath);
    this.savePath = path.resolve(savePath);
    this.collection = new Map();
    this.load();
  }

  getDataPath() {
    return this.dataPath;
  }

  setDataPath(newPath) {
    this.dataPath = path.resolve(newPath);
  }

  getSavePath() {
    return this.savePath;
  }

  setSavePath(newPath) {
    this.savePath = path.resolve(newPath);
  }

  getData(id) {
    return this.collection.get(id).data;
  }

  setData(id, data) {
    this.collection.get(id).data = data;
  }

  modifyData(id, data) {
    this.collection.get(id).modifyData(data);
  }

  getSaved(savePath = this.savePath) {
    savePath = path.resolve(savePath);
    let files = require(this.dataPath),
        dataCollection = new Map();
    files.forEach(file => {
      let data = require(path.join(this.dataPath, file));
      data.load(savePath);
      dataCollection.set(data.id, data);
    });
    return dataCollection;
  }

  load(savePath = this.savePath) {
    savePath = path.resolve(savePath);
    this.collection = this.getSaved(savePath);
  }

  save(savePath = this.savePath, collection = this.collection) {

    collection.forEach(data => {

  }

  clear() {

module.exports = SaveDataCollection;
