|
||||
A module for handling ArrayBufferLike structures, including conversion and validation utilities.
|
||||
|
||||

|
||||
Or, if you prefer using `yarn`:
|
||||
|
||||

|
||||
```
|
||||
|
||||
This will add `@push.rocks/smartbuffer` to your project's dependencies and you'll be ready to use it in your application.
|
||||
This module is essential for handling binary data in applications that require manipulation, conversion, or validation of ArrayBufferLike structures in a TypeScript environment.
|
||||
|
||||
## Usage
|
||||
|
||||
`@push.rocks/smartbuffer` is designed to make handling `ArrayBufferLike` structures easier and more intuitive, specifically in TypeScript and in environments that support ECMAScript modules. This includes web browsers, Node.js (with ESM support enabled), and Deno.
|
||||
This guide assumes familiarity with TypeScript and ECMAScript modules (ESM). We will cover practical uses of `@push.rocks/smartbuffer`, including converting between ArrayBuffer and Base64, validating buffer-like objects, and leveraging Uint8Array extras.
|
||||
|
||||
### Basic Concepts
|
||||
### Getting Started
|
||||
|
||||
Before diving into the usage examples, let’s clarify what `ArrayBufferLike` structures are. In JavaScript, the `ArrayBuffer` object is used to represent a generic, fixed-length raw binary data buffer. An `ArrayBufferLike` is any data structure that can be viewed as representing such binary data. The `Buffer` class in Node.js and `Uint8Array` are typical examples of `ArrayBufferLike` structures.
|
||||
First, ensure your environment supports TypeScript and ESM. Your `tsconfig.json` should have `module` set to `ESNext` or `CommonJS`, and `target` to at least `ES2015`.
|
||||
|
||||
### Importing the Module
|
||||
|
||||
First, import the functions you need from the module:
|
||||
Import the module functions:
|
||||
|
||||
```typescript
|
||||
import { arrayBufferToBase64, base64ToArrayBuffer, isBufferLike } from '@push.rocks/smartbuffer';
|
||||
import {
|
||||
uInt8ArrayExtras,
|
||||
uInt8ArrayToBase64,
|
||||
base64ToUint8Array,
|
||||
isBufferLike
|
||||
} from '@push.rocks/smartbuffer';
|
||||
```
|
||||
|
||||
### Converting `ArrayBuffer` to Base64 String
|
||||
The above imports bring conversion and validation utilities into your project.
|
||||
|
||||
Often, you’ll need to convert binary data represented by an `ArrayBuffer` into a Base64 encoded string. This is especially common when you need to transmit binary data over a medium that only supports text content, such as JSON.
|
||||
### Converting between Base64 and ArrayBuffer
|
||||
|
||||
Converting data to and from Base64 is crucial for handling binary data in text-based formats like JSON.
|
||||
|
||||
#### ArrayBuffer to Base64
|
||||
|
||||
To convert an `Uint8Array` to a Base64 string:
|
||||
|
||||
```typescript
|
||||
const myArrayBuffer = new ArrayBuffer(8);
|
||||
const view = new Uint8Array(myArrayBuffer);
|
||||
// Fill the buffer with some data
|
||||
view.set([8, 6, 7, 5, 3, 0, 9]);
|
||||
|
||||
const base64String = arrayBufferToBase64(myArrayBuffer);
|
||||
console.log(base64String); // Output will be a Base64 encoded string of the ArrayBuffer content
|
||||
const arrayBuffer = new Uint8Array([0, 1, 2, 3, 4, 5]).buffer;
|
||||
const base64String = uInt8ArrayToBase64(new Uint8Array(arrayBuffer));
|
||||
console.log(base64String); // Logs the Base64 representation
|
||||
```
|
||||
|
||||
### Converting a Base64 String to `ArrayBuffer`
|
||||
#### Base64 to ArrayBuffer
|
||||
|
||||
Conversely, if you have a Base64 encoded string that represents binary data, you can convert it back to an `ArrayBuffer` or a `Uint8Array` for further manipulation or use within your application.
|
||||
To convert a Base64 string back to a `Uint8Array` (and thus `ArrayBuffer`):
|
||||
|
||||
```typescript
|
||||
const base64String = "aGVsbG8gd29ybGQ="; // "hello world" in Base64
|
||||
const arrayBuffer = base64ToArrayBuffer(base64String);
|
||||
console.log(new TextDecoder().decode(arrayBuffer)); // Expects to output "hello world"
|
||||
const base64String = "AAECAwQF"; // Base64 for [0, 1, 2, 3, 4, 5]
|
||||
const arrayBuffer = base64ToUint8Array(base64String);
|
||||
console.log(arrayBuffer); // Logs the equivalent Uint8Array
|
||||
```
|
||||
|
||||
### Checking if an Object is `ArrayBufferLike`
|
||||
### Validating Buffer-like Objects
|
||||
|
||||
Sometimes you may need to validate whether a given object is an `ArrayBufferLike` structure (`ArrayBuffer`, `Uint8Array`, `Buffer`, etc.). This is useful in functions that are meant to operate on binary data and need to ensure the data passed to them is in the correct format.
|
||||
With diverse environments (web, Node.js), ensuring your data is in the correct format becomes key.
|
||||
|
||||
```typescript
|
||||
const buffer = new Uint8Array([1, 2, 3, 4]);
|
||||
const notBuffer = [1, 2, 3, 4];
|
||||
|
||||
console.log(isBufferLike(buffer)); // true
|
||||
const arrayBuffer = new ArrayBuffer(8);
|
||||
const notBuffer = {};
|
||||
console.log(isBufferLike(arrayBuffer)); // true
|
||||
console.log(isBufferLike(notBuffer)); // false
|
||||
```
|
||||
|
||||
### Practical Applications
|
||||
### Advanced Usage with `uint8array-extras`
|
||||
|
||||
The functionality provided by `@push.rocks/smartbuffer` is particularly helpful in applications dealing with file operations, network communications, or any context where binary data needs to be processed, transformed, or transmitted.
|
||||
The `uInt8ArrayExtras` export provides access to more nuanced operations on `Uint8Array` objects, including efficient data manipulation and additional conversion utilities.
|
||||
|
||||
For instance, when receiving files as part of a web API, converting these files to Base64 strings for storage or transmission is a common requirement. Similarly, when working with WebSockets or server-sent events, `ArrayBuffer` objects and their views (`Uint8Array`, etc.) are commonly used to handle binary data efficiently.
|
||||
```typescript
|
||||
// Example using uInt8ArrayExtras for direct manipulation
|
||||
const myUint8Array = new Uint8Array([10, 20, 30, 40, 50]);
|
||||
// Perform an operation directly from uInt8ArrayExtras
|
||||
console.log(uInt8ArrayExtras.someUtilityMethod(myUint8Array));
|
||||
```
|
||||
|
||||
By providing utilities to convert between binary data and Base64 strings, as well as methods to check data types, `@push.rocks/smartbuffer` simplifies the implementation of complex data handling operations. Whether you are working with IoT devices, implementing a web application that manipulates images or audio files, or dealing with any form of binary data, `@push.rocks/smartbuffer` is a valuable tool to have in your toolkit.
|
||||
### Practical Application Scenario
|
||||
|
||||
Remember to thoroughly test your applications to ensure that data integrity is maintained throughout all operations involving `ArrayBufferLike` structures.
|
||||
Imagine a scenario where your application receives image data as Base64 strings from an API. You need to convert this data into `Blob` objects for display within a web application:
|
||||
|
||||
```typescript
|
||||
async function base64ToImageBlob(base64Data: string): Promise<Blob> {
|
||||
const arrayBuffer = base64ToUint8Array(base64Data);
|
||||
return new Blob([arrayBuffer], { type: 'image/jpeg' });
|
||||
}
|
||||
|
||||
const imageBase64 = "/* Base64 data */";
|
||||
const imageBlob = await base64ToImageBlob(imageBase64);
|
||||
const imageUrl = URL.createObjectURL(imageBlob);
|
||||
document.getElementById('myImage').src = imageUrl;
|
||||
```
|
||||
|
||||
This approach shows how `@push.rocks/smartbuffer` can be integral in handling binary data within modern web applications, from conversion to practical rendering.
|
||||
|
||||
### Conclusion
|
||||
|
||||
`@push.rocks/smartbuffer` offers a comprehensive toolkit for working with ArrayBufferLike structures in TypeScript. From basic conversions to complex data validations and manipulations, it simplifies interactions with binary data across different environments.
