This sample use Model Derivative API to translate Google Drive files into Viewer. It loads 2 files and color-code the differences: green (added), red (deleted) and orange (modified). See this blog post for more information. Based on this sample.
See it live at forgegoogledriveviewerchanges.herokuapp.com.
- Forge Account: Learn how to create a Forge Account, activate subscription and create an app at this tutorial.
- Google Drive: end-user account with 2 Revit files to compare
- Google Developer Account: Visit the Google APIs Console, Log in or Sign up, follow the steps to Create a Credential. For this new app, use http://localhost:3000/api/google/callback/oauth as redirect_uri. Make sure you activate Google Drive & Google People APIs, this sample uses both scopes. Finally, take note of the client_id and client_secret.
Install NodeJS.
Clone this project or download it. It's recommended to install GitHub desktop. To clone it via command line, use the following (Terminal on MacOSX/Linux, Git Shell on Windows):
git clone https://github.com/augustogoncalves/model.derivative-nodejs-google.drive.viewer.changes
To run it, install the required packages, set the enviroment variables with your client ID & secret and finally start it. Via command line, navigate to the folder where this repository was cloned and use the following:
Mac OSX/Linux (Terminal)
npm install
export FORGE_CLIENT_ID=<<YOUR CLIENT ID FROM FORGE DEVELOPER PORTAL>>
export FORGE_CLIENT_SECRET=<<YOUR FORGE CLIENT SECRET>>
export GOOGLE_CLIENT_ID=<<YOUR CLIENT ID FROM GOOGLE DEVELOPER>>
export GOOGLE_CLIENT_SECRET=<<YOUR GOOGLE CLIENT SECRET>>
npm run dev
Windows (use Node.js command line from Start menu)
npm install
set FORGE_CLIENT_ID=<<YOUR CLIENT ID FROM FORGE DEVELOPER PORTAL>>
set FORGE_CLIENT_SECRET=<<YOUR FORGE CLIENT SECRET>>
set GOOGLE_CLIENT_ID=<<YOUR CLIENT ID FROM GOOGLE DEVELOPER>>
set GOOGLE_CLIENT_SECRET=<<YOUR GOOGLE CLIENT SECRET>>
npm run dev
Open the browser: http://localhost:3000.
Important: do not use npm start locally, this is intended for PRODUCTION only with HTTPS (SSL) secure cookies.
To deploy this application to Heroku, the Callback URL & redirect_uri must use your .herokuapp.com address. After clicking on the button below, at the Heroku Create New App page, set your Client ID & Secret and the correct callback URL.
Watch this video on how deploy this sample to Heroku.
All Autodesk Forge NPM packages are included by default, see complete list of what's available at NPM website. OAuth, Model Derivative and OSS are used. Google Drive for NodeJS is googleapis. Some other non-Autodesk packaged are used, including express and its session/cookie middlewares (express-session and cookie-parser) for user session handling. The front-end uses bootsrap and jquery.
For local development/testing, consider use nodemon package, which auto restart your node application after any modification on your code. To install it, use:
sudo npm install -g nodemon
Then, instead of npm run dev, use the following:
npm run nodemon
Which executes nodemon server.js --ignore www/, where the --ignore parameter indicates that the app should not restart if files under www folder are modified.
