[!WARNING] This template is deprecated and this repository is archived.

k6 has native ES6+ and TypeScript support since v0.52.0 (released June 2024). Set the --compatibility-mode=experimental_enhanced option to use it, and check the documentation for the details. The Babel/Webpack bundling described below is no longer necessary; the contents are kept for historical reference only.

This is a template repository showing how to use Babel and Webpack to bundle the different files into CommonJS modules, using its webpack.config.js configuration.

In this project, you can write k6 tests using:

1. node module resolution.
2. external node modules and getting them automatically bundled.
3. unsupported ES+ features like the optional chaining ( ?. ) operator.

Installation

Click Use this template to create a repository from this template.

Clone the generated repository on your local machine, move to the project root folder and install the dependencies defined in package.json

npm install

Running the test

Attempting to run the tests in src will fail because:

• k6 does not know how to resolve node modules.
• k6 does not recognize some ES+ features like the optional chaining ( ?. ) operator.

To address this, we'll use Webpack to bundle the dependencies and polyfill ES+ features.

npm run bundle

This command creates the final test files to the ./dist folder.

Once that is done, we can run our script the same way we usually do, for instance:

k6 run dist/optional-chaining-test.js
# or 
k6 run dist/faker-test.js
