Troubleshooting LaunchDarkly API connectivity in Pakistan – LaunchDarkly

Affected: All SDKs

Overview

Some customers and end-users in Pakistan have experienced difficulty maintaining a persistent connection to LaunchDarkly.

While LaunchDarkly is a product with global reach, inconsistencies between the internet services of different countries can make it difficult to predict where we might have outages. Some customers have reported difficulty maintaining a connection to LaunchDarkly from Pakistan.

We offer these customers the following alternatives to a conventional LaunchDarkly process.

Solution

Configure your SDKs to either use the Relay Proxy (deployed in a cloud region geographically close to Pakistan, such as AWS Mumbai or Azure UAE, to improve connectivity and reduce latency), or bootstrap flags (for Client-side JavaScript-based SDKs only).

For more information about the Relay Proxy, read: Relay Proxy

Client-side SDKs

Below is an example of how to bootstrap flags from local storage for the JavaScript SDK.

const options = { bootstrap: 'localStorage' }

const client = LDClient.initialize('client-side-id-123abc', context, options);

try {
  await client.waitForInitialization(5);
  proceedWithSuccessfullyInitializedClient();
} catch(err) {
  // Client failed to initialized or timed out
  // variation() calls return fallback values until initialization completes
}

Below is an example of how to connect the SDK to the Relay Proxy for the JavaScript SDK.

const options = {
  streamUrl: 'https://your-relay-proxy.com:8030',
  baseUrl: 'https://your-relay-proxy.com:8030',
  eventsUrl: 'https://your-relay-proxy.com:8030'
};

Mobile SDKs

Below is an example of how to connect the SDK to the Relay Proxy for the iOS SDK in Swift.

var ldConfig = LDConfig(mobileKey: "mobile-key-123abc", autoEnvAttributes: .enabled)
ldConfig.streamUrl = URL(string: "https://your-relay-proxy.com:8030")
ldConfig.baseUrl = URL(string: "https://your-relay-proxy.com:8030")
ldConfig.eventsUrl = URL(string: "https://your-relay-proxy.com:8030")

Server-side SDKs

Below is an example of how to connect the SDK to the Relay Proxy for the Node.js Server-side SDK in Typescript.

import * as ld from '@launchdarkly/node-server-sdk';

const options ld.LDOptions = {
  streamUri: 'https://your-relay-proxy.com:8030',
  baseUri: 'https://your-relay-proxy.com:8030',
  eventsUri: 'https://your-relay-proxy.com:8030',
};
