==================
remove a file from previous history:
git filter-branch -f --index-filter 'git rm --cached -f -q --ignore-unmatch "$file"' --prune-empty --tag-name-filter cat -- --all
->$file = file path (related to the root folder)

then force push:
git push origin master --force
==================
eldeeb/samples/ contain useful samples (ex: models,data,pages,...)
==================
/db/
  __db/step0/ : the original data (.json) from the old project (sqlite & php)
  schema
    - $collection.js: schema for the original colletion (contains the original data)
    - tmp.$collection.js : temporary collections contains the final cached data (tmp collection use the same indexes of the original collection), use mongoDB.aggregate.$out
    - $db.$collection.js : collection in $db database
  examples
$data.js => get data from the database
$data_save.js => send data to db
$data_update -> update the corresponding tmp collection
index.js => connect to the database and returns eldeeb.promise

add modifiedAt=true to every schema object (if not added will create modifiedAt as a string not date object)

nuxt-edge is the beta version of nuxt https://medium.com/nuxt/nuxt-2-is-coming-oh-yeah-212c1a9e1a67
==================
[11.12.2018] using commonJs:require & module.exports causes some problems (so we switched to ES6:import & export):
 - eldeeb/lib/index.js->isArray->obj[Symbol.iterator] exits the code without any error, 
 - pages/test.vue : test=require('../test.js') 
   test.js : require('./eldeeb/..')/*contains 'Symbol.iterator'*/ module.exports="OK"
    using module.exports: test={}
    using import & export: test=OK
- ES6 is the standard spec of js, so we will use it (i.e: import & export)
- currently node.js supports ES6 module system in expremental mode only, Nuxt uses babel transpiler to convert them to commonJS module system
