@arcjet/body

Arcjet utilities for getting the body from a Node.js Stream.

Installation

npm install -S @arcjet/body

Example

import { readBody } from "../index";

// Some stream.Readable-like object, such as node's `http.IncomingMessage`
const request = new IncomingMessage();

// Returns the body as a utf-8 encoded string
const body = await readBody(request, { limit: 1024 });
console.log(body);

Implementation

The implementation of this library is based on the raw-body package. Licensed MIT with licenses included in our source code.

We've chosen to re-implement the logic to read the body from the stream to keep the dependency tree for our packages as light as possible. Our implementation only provides the functionality that we need, specifically it excludes the functionality to return the stream as a buffer and always parses it as a utf-8 string. The interface was also changed to only support promises rather than the sync implementation provided by raw-body.
