Mongo Helper
This is a simple wrapper created to make it easier for us to prototype systems quickly with minimal errors. My priority here is to keep things simple, rather than giving the user a lot of options.
NOTE: Don't use this if you don't already know how to interact with MongoDB. Using Mongo Helper is no excuse for not understanding the underlying code.
Installing
THIS IS NOT IN NPM YET. DISREGARD THE FOLLOWING.
You can either install it by adding the following dependency in package.json
:
"dependencies": {
"mongoHelper": "*" //Using * for versioning isn't recommended. I'll fix that in the future.
}
and then running npm install
or by running npm install mongoHelper
.
YOU MAY CEASE YOUR DISREGARDING NOW.
Usage
Now that you've installed mongoHelper, how can you use it?
First, navigate to node_modules/mongoHelper
and open up config.js
. This is initalized with some defaut settings, but you probably want to alter them to meet your needs. Then, require the mongoHelper object with:
var mongoHelper = require('mongoHelper');
Currently, only insert and find are implemented.
####Insert
Insert takes three parameters: coll
, query
, and next
.
coll
is a string representing the collection we want to insertquery
intoquery
is the object to be inserted into the collectionnext
is a function that will be called after the db operations finish. The database is closed beforenext
is called, so you can call another db operation withnext
.
For example, if I wanted to insert {foo: 'bar'}
into the foobar
collection (and had required it like above, I would write:
mongoHelper.insert('foobar', {foo: 'bar'});
If I then wanted to run myFunc
after that:
mongoHelper.insert('foobar', {foo: 'bar'}, myfunc);
####Find Like insert, find takes three parameters. The one change is that the results of the find statement will be passed to the function you input.
####Remove
The data removed is passed to next
.
