Serializing Cookies in JavaScript

Introduction

In this lab, we will be exploring the concept of serializing cookies in JavaScript. Cookies are an essential part of web development, and it is crucial to understand how to handle them properly. By the end of this lab, you will be able to serialize a cookie name-value pair into a Set-Cookie header string using template literals and encodeURIComponent().

How to Serialize a Cookie

To start practicing coding, open the Terminal/SSH and type node. Then, follow these steps to serialize a cookie name-value pair into a Set-Cookie header string:

1. Use template literals and encodeURIComponent() to create the appropriate string.
2. Implement the serializeCookie function by passing in the name and val parameters.
3. The function will return a string that is properly serialized.

Here is an example of how to use the serializeCookie function:

const serializeCookie = (name, val) =>
  `${encodeURIComponent(name)}=${encodeURIComponent(val)}`;

serializeCookie("foo", "bar"); // 'foo=bar'

In this example, the serializeCookie function takes in foo as the cookie name and bar as the cookie value, and returns a serialized cookie string of foo=bar.

Summary

Congratulations! You have completed the Serialize Cookie lab. You can practice more labs in LabEx to improve your skills.
