launchdarkly-js-client-sdk 2.20.0 on Node.js NPM

[2.20.0] - 2021-10-15

New property LDOptions.requestHeaderTransform allows custom headers to be added to all HTTP requests. This may be necessary if you have an Internet gateway that uses a custom header for authentication. Note that custom headers may cause cross-origin browser requests to be rejected unless you have a way to ensure that the header name also appears in Access-Control-Allow-Headers for CORS preflight responses; if you are connecting to the LaunchDarkly Relay Proxy, it has a way to configure this.
