#Autodesk view and data API Node.js Basic Sample

##Description

A sample demonstrating how to load a model into web application with the Autodesk View & Data API. This web application has a basic Node.js server and JavaScript/HTML5 client

##Dependencies

Install Node.js on your machine and clone this repo. Download the project' dependencies using npm before running the app by running the following command

npm install

on the node.js console. This will install the following node.js modules in the project.

• express
• request
• serve-favicon

This sample does not includes the workflow of uploading models. It depends on other workflow samples to upload models, get model URN. Please follow Setup/Usage Instructions.

##Setup/Usage Instructions

You can work with production or staging Autodesk View and Data environments. By default, the project is setup with the production server.

With the production server, you got 2 options to setup and run this sample.

• The upload tool provides some existing models. Choose any one of them, or upload one of your own models with upload tool. The upload tool will generate a URN of the model that you need later.
• Copy this URN in /www/views/index.js at line #18
  

var urnprod = 'your_urn_here';

• In /www/views/index.js, at line #36, change value of tokenurl to the access token you can generate from 'http://still-spire-1606.herokuapp.com/api/rawtoken'
• Run the server from the Node.js console, by running the follwing command:
  

node server.js

• Connect to server locally using a WebGL-compatible browser: http://localhost:3000/node/basic

Option B: Use your own credentials and upload models on your account

• Apply your own credentials from http://developer.autodesk.com
• Install Node.js
• Run "npm install" command from the server directory to install the necessary packages which are mentioned in Dependencies.
• Replace the place holder with your own credentials in credentials.js
• Upload one of your model in your account and get its URN using other workflow sample,for example, this workflow sample in .net winform application if you are using windows or this workflow sample in Mac OS Swift if you are using Mac.
• Get your model urn from the workflow sample, and copy this URN in /www/views/index.js, replace the one for "urnprod", around line #20.
• In /www/views/index.js, around line #28, make sure the variable staging is false.
• In /www/views/index.js, around line #31, change value of tokenurl to get token through Node.js server
• In /www/views/index.html, use viewer3D.min.js and style.css from production environment
• Run the server: "node server.js" from command line
• Connect to server locally using a WebGL-compatible browser: http://localhost:3000/node/basic

To work with staging, only option B is available currently.

• Apply your own credentials from http://developer-stg.autodesk.com
• Install Node.js
• Run "npm install" command from the server directory to install the necessary packages which are mentioned in Dependencies..
• Replace the place holder with your own credentials in credentials-stg.js
• Upload one of your model in your account and get its URN using other workflow sample,for example, this workflow sample in .net winform application if you are using windows or this workflow sample in Mac OS Swift if you are using Mac. But please use staging URL to proceed the workflow.
• Get your model urn from the workflow sample, and copy this URN in /www/views/index.js, replace the one for "urnstg", around line #23.
• In /www/views/index.js, around line #28, make sure the variable staging is true.
• In /www/views/index.js, around line #31, change value of tokenurl to get token through Node.js server
• In /www/views/index.html, use viewer3D.min.js and style.css from staging environment
• Run the server: "node server.js" from command line
• Connect to server locally using a WebGL-compatible browser: http://localhost:3000/node/basic
