What is @optimizely/js-sdk-utils?
@optimizely/js-sdk-utils is a utility library for the Optimizely JavaScript SDK. It provides various helper functions and utilities to facilitate the implementation and management of Optimizely experiments and feature flags in JavaScript applications.
What are @optimizely/js-sdk-utils's main functionalities?
Event Dispatcher
The Event Dispatcher utility allows you to create and dispatch events to the Optimizely logging endpoint. This is useful for tracking user interactions and experiment data.
const { createEventDispatcher } = require('@optimizely/js-sdk-utils');
const dispatcher = createEventDispatcher();
const event = {
url: 'https://logx.optimizely.com/v1/events',
params: {
account_id: '12345',
project_id: '67890',
visitors: [{
visitor_id: 'visitor_1',
attributes: [],
snapshots: []
}]
}
};
dispatcher.dispatchEvent(event).then(response => {
console.log('Event dispatched successfully:', response);
}).catch(error => {
console.error('Error dispatching event:', error);
});
Logger
The Logger utility provides a simple logging mechanism that can be configured with different log levels. This helps in debugging and monitoring the SDK's behavior.
const { createLogger } = require('@optimizely/js-sdk-utils');
const logger = createLogger({ logLevel: 'info' });
logger.log('info', 'This is an info message');
logger.log('error', 'This is an error message');
Error Handler
The Error Handler utility provides a standardized way to handle errors within the Optimizely SDK. It can be used to catch and process errors, ensuring that they are logged and managed appropriately.
const { createErrorHandler } = require('@optimizely/js-sdk-utils');
const errorHandler = createErrorHandler();
try {
throw new Error('Something went wrong');
} catch (error) {
errorHandler.handleError(error);
}
