Nedb Multiple Collection Single Datastore

Question

I am a new to nedb. Its a kinda what sqlite is for sql community but for the node.js community. [https://github.com/louischatriot/nedb] I wanted to ask is possible to have multiple collections in a single database file (datastore). If there is, could please show me some code sample on how to go about it? I have tried this: ``` var Datastore = require('nedb'), databaseURL="tudls.db", db = new Datastore({filename: databaseURL, autoload: true}); ``` This creates a single datastore called db. From the documentation, I saw that nedb is mongo-like. So to insert a record I tried this: ``` app.post('/todos', function(req, res){ var task = req.body.text; db.todols.insert({text: task, done: false}, function(err, saved){ if(err||!saved){ res.send("Task not saved..."); } res.send("Task saved...");}); }); ``` However, I get a 'cannot call method insert of undefined.' I thought that if I call the collection name (todols) when inserting a record it would work so that I can proceed to add another col…

Accepted Answer

This really is a "lite" interpretation of MongoDB and as such there really isn't the same concept of "databases" and "collections" that exists in the full featured product, as well as omitting a lots of other features.

If you want things to appear as if you do have various "collections", then as suggested in the manual page you define various `DataStore` objects within a structure to make things look that way:

```
var db = {};
db.todols = new DataStore('/path/to/todols.db');
db.other = new DataStore('/path/to/other.db');
```

That makes it appear that you have "collections" which are in fact to "neDB" actually just `DataStore` objects.
