Install RealSense Extensions

The Crosswalk RealSense Sample App source code will be used as an example in following steps.

Enter the root of the app where it should have the manifest.json file.

c:\> cd c:\path\to\rs_sample_v19.6.1_src\src

Create node_modules folder inside the root of the app. Otherwise, npm might install extensions in wrong places.

c:\path\to\rs_sample_v19.6.1_src\src> mkdir node_modules

Install Depth Enabled Photography Extension.

c:\path\to\rs_sample_v19.6.1_src\src> npm install crosswalk-extension-dep

c:\path\to\rs_sample_v19.6.1_src\src> npm install crosswalk-extension-face

Install Hand Tracking Extension.

c:\path\to\rs_sample_v19.6.1_src\src> npm install crosswalk-extension-hand

Install Scene Perception Extension.

c:\path\to\rs_sample_v19.6.1_src\src> npm install crosswalk-extension-sp

(Optional) Verify the installation by

c:\path\to\rs_sample_v19.6.1_src\src> npm list
c:\path\to\rs_sample_v19.6.1_src\src
