Advanced tools
Package description
The @aws-sdk/util-body-length-browser package is a utility module designed for use in browser environments to calculate the length of a request body. This is particularly useful when working with AWS SDK for JavaScript (v3) in browser environments, as it helps in determining the content length of various types of request bodies such as strings, binary data, and Blob objects. This functionality is crucial for correctly setting the Content-Length header in HTTP requests, which is often required by web services to process requests correctly.
Calculate string body length
This feature allows you to calculate the length of a string body. It's useful when you need to determine the size of a text-based request body before sending it in an HTTP request.
const { calculateBodyLength } = require('@aws-sdk/util-body-length-browser');
const bodyLength = calculateBodyLength('Hello World');
console.log(bodyLength);Calculate Blob body length
This feature enables the calculation of the length of a Blob object's body. It's particularly useful for browser-based applications that need to send binary data or files as part of an HTTP request.
const { calculateBodyLength } = require('@aws-sdk/util-body-length-browser');
const blob = new Blob(['Hello World'], { type: 'text/plain' });
blob.arrayBuffer().then(buffer => {
const bodyLength = calculateBodyLength(buffer);
console.log(bodyLength);
});The 'buffer' package provides similar functionality in terms of handling binary data in Node.js environments. While @aws-sdk/util-body-length-browser is tailored for browser environments and focuses on calculating body lengths, 'buffer' offers a more comprehensive set of tools for manipulating binary data in Node.js.
The 'blob-util' package offers a set of utilities for working with Blob objects in the browser, including converting between Blob, base64 strings, and array buffers. While it shares some functionality with @aws-sdk/util-body-length-browser in terms of handling Blob objects, its focus is broader, covering conversions and manipulations rather than just calculating body lengths.
