Hi,
I have application in nodejs and I need to load when you start a collection
from mongo to in-memory db. then in use only this object, not mongo
collection.
How to make?
It occurred to me:
*TasksCollection.coffee*
class TasksCollection
constructor: (@Tasks, @Datastore) ->
createCollection: ->
@Tasks.find {}, (e, tasks) ->
return throw e if e isnt null
@Datastore.insert tasks (e) ->
return throw e if e isnt null
# now I have data in in-memory db
module.exports = exports = TasksCollection
*app.coffee*
TaskMongoCollection = ...
DataStore = ...
TasksCollection = require './TasksCollection'
new TasksCollection TaskMongoCollection, new DataStore
###
In TasksCollection should be the object of a collection of Mongo other
methods for insertion into the collection and retrieval
Object TaskCollection I want to pass on:
###
app.use (req, res, next) ->
req.db = TasksCollections
###
I do not understand asynchronous work in nodejs - until we learn.
Previously I worked in PHP so i got thinking.
Put simply:
1). Start the application
2). Retrieve a collection of monga into in-memory database (I use nedb)
3). polling place in monga want to inquire into the in-memory
Thanks
