Developing Cloud of Things web applications
If you develop a Cloud of Things web application using the Web SDK, for an Edge appliance configured with a certificate not trusted by Node.js (for example, a self-signed certificate), then you must ensure that Node.js trusts the root certificate.
To add the Edge appliance’s self-signed certificate to the Node.js trust store, set the environment variable NODE_EXTRA_CA_CERTS to the path of the certificate before executing the npm commands.
Example:
On Windows Powershell:
$env:NODE_EXTRA_CA_CERTS=<path-to-the-certificate>\certificate.pem
On Windows command prompt:
set NODE_EXTRA_CA_CERTS=<path-to-the-certificate>\certificate.pem
On Linux platforms:
export NODE_EXTRA_CA_CERTS=<path-to-the-certificate>/certificate.pem
