What are @segment/loosely-validate-event's main functionalities?

Validate Event

This feature allows you to validate a Segment event object. If the event is valid, it proceeds without error; otherwise, it throws an error detailing what is wrong with the event.

const validate = require('@segment/loosely-validate-event');

const event = {
  type: 'track',
  event: 'User Signup',
  properties: {
    plan: 'Pro'
  }
};

try {
  validate(event);
  console.log('Event is valid');
} catch (err) {
  console.error('Event validation failed:', err.message);
}

joi

Joi is a popular schema description language and data validator for JavaScript objects. It allows you to create blueprints or schemas for JavaScript objects to ensure they conform to the expected structure. While @segment/loosely-validate-event is tailored for Segment events, Joi provides a more flexible and comprehensive validation solution for various data types.

yup

Yup is a JavaScript schema builder for value parsing and validation. It is similar to Joi but is often preferred for its simplicity and ease of use. Yup can be used to validate any kind of data, making it more versatile compared to the specialized @segment/loosely-validate-event.
