TextEncoder and TextDecoder implementations for k6

Welcome to xk6-encoding, an xk6 extension that brings support for Javascript's TextEncoder and TextDecoder to k6, enabling you to seamlessly handle various text encodings during your performance tests.

Features

• Text Encoding: Convert your strings into byte streams with support for various encoding formats including UTF-8, UTF-16, and Windows-1252.
• Text Decoding: Decode byte streams back to strings with ease, even when processing the data in chunks.
• Flexible Options: Handle Byte Order Marks (BOM) and determine behavior on decoding invalid data.

Why Use xk6-encoding?

If you're working with systems that utilize various text encodings or if you're aiming to test the performance of encoding/decoding tasks, this extension will be invaluable for your k6 tests.

Getting Started

1. Make sure you have the latest version of the xk6 tool installed:

go install go.k6.io/xk6/cmd/xk6@latest

1. Build your custom k6 binary:

xk6 build --with github.com/oleiade/xk6-encoding@latest

1. Use in your k6 script: To encode text:

import { TextEncoder } from 'k6/encoding';
const encoder = new TextEncoder("utf-8");
const encoded = encoder.Encode("Your text here");

To decode text:

import { TextDecoder } from 'k6/encoding';
const decoder = new TextDecoder("utf-8");
const decoded = decoder.Decode(encodedData);

1. Run your k6 test with the custom k6 binary you built:

./k6 run your-test-script.js

Supported Encodings

• utf-8: Standard encoding for the web.
• utf-16le and utf-16be: Unicode encodings that can represent any character in the Unicode standard.
• windows-1252: A character encoding of the Latin alphabet, used by default in the legacy components of Microsoft Windows.
