NodeJS SDK for Dropbox API

README.md

dbox

A Node.JS convenience wrapper around the Dropbox API. Simplifies OAuth handshake and removes HTTP ceremony.

Installation

I always recommend you bundle your dependencies with your application. To do this, create a package.json file in the root of your project with the minimum information...

{
  "name": "yourapplication",
  "version": "0.1.0",
  "dependencies": {
    "dbox": "0.6.1"
  }
}

Then run the following command using npm...

npm install

OR, if you just want to start playing with the library run...

npm install dbox

API Overview

dbox methods (where dbox is set from requiring the dbox library)...

app                 <-- creates application object

app methods (where app is created from the above app call)...

requesttoken        <-- creates request token for getting request token and authorization url
accesstoken         <-- creates access token for creating a client object
client              <-- creates client object with access to users dropbox account

client methods (where client is created from the above client call)...

How to Use

Creating a functional dbox client is a four step process.

  1. create an app using application credentials provided by dropbox
  2. obtain request token to use for generation access token
  3. have user visit authorization URL to grant access to your application
  4. create a client using access token that was generated earlier

Step 1

var dbox  = require("dbox")
var app   = dbox.app({ "app_key": "umdez34678ck01fx", "app_secret": "tjm89017sci88o6" })

Step 2

Authorization is a three step process.

a) Get a request token...

app.requesttoken(function(status, request_token){
  console.log(request_token)
})

b) User must visit the url to grant authorization to the client...

https://www.dropbox.com/1/oauth/authorize?oauth_token=#{ request_token.oauth_token }

c) Generate our access token with the request token...

app.accesstoken(request_token, function(status, access_token){
  console.log(access_token)
})

Step 3

var client = app.client(access_token)

Now we have a client that gives us access to all the api functionality.
