What is dexie?

Dexie is a wrapper for IndexedDB, a low-level API for client-side storage of significant amounts of structured data, including files/blobs. Dexie simplifies the use of IndexedDB by providing a more developer-friendly API and additional features such as versioning, transactions, and observability.

What are dexie's main functionalities?

Database Initialization

This code initializes a new Dexie database named 'MyDatabase' and defines a schema for a 'friends' table with auto-incrementing primary key 'id' and indexed fields 'name' and 'age'.

const db = new Dexie('MyDatabase');
db.version(1).stores({
  friends: '++id,name,age'
});

Adding Data

This code adds a new record to the 'friends' table with the name 'John' and age 25.

db.friends.add({name: 'John', age: 25});

Querying Data

This code queries the 'friends' table for all records where the age is below 30 and logs the results to the console.

db.friends.where('age').below(30).toArray().then(friends => {
  console.log(friends);
});

Updating Data

This code updates the record with primary key 1 in the 'friends' table, setting the age to 26.

db.friends.update(1, {age: 26});

Deleting Data

This code deletes the record with primary key 1 from the 'friends' table.

db.friends.delete(1);
