Deno's localStorage API provides a way to store key-value pairs in a
web-like environment, similar to the Web Storage API found in browsers.
It allows developers to persist data across sessions in a Deno application.
This API is particularly useful for applications that require a simple
and effective way to store data locally.
- Key-Value Storage: Stores data as key-value pairs.
- Persistent: Data is retained even after the application is closed.
- Synchronous API: Operations are performed synchronously.
localStorage is similar to sessionStorage, and shares the same
API methods, visible in the Storage type.
When using the --location flag, the origin for the location is used to
uniquely store the data. That means a location of http://example.com/a.ts
and http://example.com/b.ts and http://example.com:80/ would all share the
same storage, but https://example.com/ would be different.
For more information, see the reference guide for
Web Storage
and using
the --location flag.

Example 1
// Set a value in localStorage
localStorage.setItem("key", "value");
// Get a value from localStorage
const value = localStorage.getItem("key");
console.log(value); // Output: "value"
// Remove a value from localStorage
localStorage.removeItem("key");
// Clear all values from localStorage
localStorage.clear();
