If your environment requires SSL decryption, you can set the path to CA bundle in the env var
twilio-node supports lazy loading required modules for faster loading time. Lazy loading is disabled by default. To enable lazy loading, simply instantiate the Twilio client with the
lazyLoading flag set to
var accountSid = processenvTWILIO_ACCOUNT_SID; // Your Account SID from www.twilio.com/consolevar authToken = processenvTWILIO_AUTH_TOKEN; // Your Auth Token from www.twilio.com/consoleconst client = accountSid authTokenlazyLoading: true;
Specify Region and/or Edge
To take advantage of Twilio's Global Infrastructure, specify the target Region and/or Edge for the client:
var accountSid = processenvTWILIO_ACCOUNT_SID; // Your Account SID from www.twilio.com/consolevar authToken = processenvTWILIO_AUTH_TOKEN; // Your Auth Token from www.twilio.com/consoleconst client = accountSid authTokenregion: 'au1'edge: 'sydney';
Alternatively, specify the edge and/or region after constructing the Twilio client:
const client = accountSid authToken;clientregion = 'au1';clientedge = 'sydney';
This will result in the
