node-service-protocol

Determine protocol for connecting to a service using consul for resolving local hostname if necessary.

The environment variable TLS_UNPROTECTED is used with the folowing values:

• none No unprotected connections are used and getProtocol always returns https
• world All connections are unprotected and getProtocol always returns http
• loopback (default) Connections to localhost are unprotected and getProtocol returns http, external connections are protected and getProtocol return https.

npm install @sealsystems/service-protocol

Usage

const serviceProtocol = require('@sealsystems/service-protocol');

const isLocal = serviceProtocol.isLocal(consul, 'localhost');
// --> true

getProtocol(consul, hostname);

Returns the protocol for connection to a service on host hostname.
