LaunchDarklyProvider
Component
The LaunchDarklyProvider
is a React component that is designed to work with the LaunchDarkly feature flag management system. It initializes the LaunchDarkly client, retrieves feature flags, and provides them to its child components via a context. The component also handles cleanup when it's unmounted.
Using LaunchDarklyProvider
Component
To integrate the LaunchDarklyProvider
component into your React application, follow these steps:
1. Import Dependencies
First, make sure you've imported the necessary dependencies and custom modules in your React file:
import React from 'react';
import { LaunchDarklyProvider } from 'launchdarkly-context-provider'
2. Define User Context and Feature Flags
Define the user context and initial feature flags you want to use within your application. The user context typically includes a unique user key:
const userContext = {
key: 'unique_user_key',
// Add other user context properties as needed
};
const initialFeatureFlags = {
featureFlag1: false,
featureFlag2: true,
// Add other feature flags as needed
};
3. Wrap Your Application with LaunchDarklyProvider
Wrap your application or a specific part of it with the LaunchDarklyProvider
. Provide the required props:
launchDarklyClientSideId
: Your LaunchDarkly client-side ID.launchDarklyUserContext
: The user context you defined in step 2.launchDarklyFeatureFlags
: The initial feature flags you defined in step 2.
function App() {
return (
<LaunchDarklyProvider
launchDarklyClientSideId="YOUR_CLIENT_SIDE_ID"
launchDarklyUserContext={userContext}
launchDarklyFeatureFlags={initialFeatureFlags}
>
{/* Your application components go here */}
</LaunchDarklyProvider>
);
}
4. Access Feature Flags in Your Components
Within your application components, you can access the feature flags provided by the LaunchDarklyProvider
by using the useLaunchDarkly
hook.
First, import the useLaunchDarkly
hook:
import { useLaunchDarkly } from 'launchdarkly-context-provider'
Then, use the useLaunchDarkly
hook to access the feature flags:
function MyFeatureComponent() {
const featureFlags = useLaunchDarkly();
// Access individual feature flags as needed
const isFeatureFlag1Enabled = featureFlags.featureFlag1;
const isFeatureFlag2Enabled = featureFlags.featureFlag2;
// Render your component based on feature flag values
// ...
}
Now your components can make decisions and render content based on the state of your feature flags.
