indexdb insert binary

This article provides a comprehensive guide to efficiently insert binary data into IndexedDB. It outlines step-by-step instructions for converting binary data to an array buffer, creating an object store, transaction, and object, setting the object's

How to efficiently insert binary data into IndexedDB?

IndexedDB is a powerful data storage API that can be used to store various types of data, including binary data. To efficiently insert binary data into IndexedDB, follow these steps:

1. Convert your binary data to an array buffer: IndexedDB works with ArrayBuffer objects, so you need to convert your binary data to an array buffer first. You can use the ArrayBuffer.from() method for this purpose.ArrayBuffer.from() method for this purpose.

2. Create a new IndexedDB object store: An object store is a container for data in IndexedDB. You need to create a new object store to store your binary data.

3. Create a new IndexedDB transaction: A transaction is a unit of work in IndexedDB. You need to create a new transaction to insert your binary data.

4. Create a new IndexedDB object: An object is a representation of a record in IndexedDB. You need to create a new object to store your binary data.

5. Set the value of the object to the array buffer: The value of an object can be set to an array buffer. Set the value of your object to the array buffer that you created in step 1.

6. Add the object to the object store: Add the object to the object store that you created in step 2.

7. Commit the transaction: Once you have added the object to the object store, you need to commit the transaction to save the changes.

Example:

<code class="js">// Create an array buffer from binary data
const buffer = ArrayBuffer.from(binaryData);

// Create a new object store
const store = db.createObjectStore("myBinaryData", { keyPath: "id", autoIncrement: true });

// Create a transaction
const transaction = db.transaction(["myBinaryData"], "readwrite");

// Create a new object
const object = transaction.objectStore("myBinaryData").create({});

// Set the value of the object to the array buffer
object.value = buffer;

// Add the object to the object store
transaction.objectStore("myBinaryData").add(object);

// Commit the transaction
transaction.commit();</code>

Can I use IndexedDB to store images as binary objects?

Yes, you can use IndexedDB to store images as binary objects. To store an image as a binary object in IndexedDB, follow these steps:

1. Read the image file as an array buffer: Use the FileReader

2. Create a new IndexedDB object store: An object store is a container for data in IndexedDB. You need to create a new object store to store your binary data.

3. Create a new IndexedDB transaction: A transaction is a unit of work in IndexedDB. You need to create a new transaction to insert your binary data.

4. Create a new IndexedDB object:

5. Set the value of the object to the array buffer:

6. Add the object to the object store:

7. Commit the transaction:
