UserInfo

File: user-info.interface.ts

Introduction

The UserInfo interface is part of the error-enhanced library and focuses on capturing user-specific data related to an error event. This can include session IDs, user roles, authentication tokens, and more. Having this level of user-specific detail aids in debugging and helps in resolving user-specific issues more efficiently.

Properties

Property	Type	Description
sessionId	string	A read-only property indicating the user's session ID.
roles	string[]	A read-only array of roles associated with the user.
authToken	string	A read-only property for the authentication token.
ipAddress	string	A read-only property for the user's IP address.
userAgent	string	A read-only property for the user's agent, usually a browser.
actionHistory	string[]	A read-only array capturing a history of user actions leading up to the error.

Methods

Method	Return Type	Description
setUser(user: string)	this	Sets the user identifier. Allows for method chaining.
setSessionId(sessionId: string)	this	Sets the session ID. Allows for method chaining.
setRoles(roles: string[])	this	Sets the user roles. Allows for method chaining.
setAuthToken(token: string)	this	Sets the authentication token. Allows for method chaining.
setIpAddress(ip: string)	this	Sets the user's IP address. Allows for method chaining.
setUserAgent(userAgent: string)	this	Sets the user agent. Allows for method chaining.
addActionToHistory(action: string)	this	Adds an action to the user's action history. Allows for method chaining.

Example Usage

const error = new ErrorEnhanced([
  new UserInfoEnhancer()
]);

// Setting properties
error
  .setSessionId('abc123')
  .setRoles(['admin', 'user']);

// Accessing properties
console.log(error.sessionId);  // 'abc123'
console.log(error.roles);  // ['admin', 'user']

Best Practices

• Always set user-related properties as soon as the error is captured for more accurate debugging.

• Use addActionToHistory to maintain a running log of user actions leading up to an error, which can be invaluable for debugging.

Conclusion

The UserInfo interface provides a structured way to capture user-specific details when an error occurs. This facilitates debugging and issue resolution, making it an indispensable part of your error management strategy.
