Lua and JavaScript (JS) share most of the fundamental logical constructs and control flow mechanisms that are commonly found in general purpose programming languages. Same goes for the load testing oriented APIs that we’ve added in each respective product. This section will look at how to convert Lua APIs into the JS equivalent.
High-level differences
. But calling through Lua brackets counts from 1: array1. APIs and auto-coercion for Lua tables and NS. Must copy/convert when this happens. When converting to NS, because Lua tables can be either, both data NS structures get created until one can be discarded. NS. can only hold objects. Numbers auto-boxed in NSNumber. /. Constructs a new HTTPInputGenerator using a Lua generation script. The Lua script must contain the onInit and onCall(callnum) functions. onCall(callnum) must return the HTTP request for a specific call with number callnum. callnum begins at 1 (Lua convention) and increments for each call. It resets back to 1. if onCall returns nil.
On highest level there are some differences to be aware of before we continue on into more details.
Loading of builtin modules and APIs
Lua
In Lua all the available functionality is loaded by default, APIs can be called right away without explicit loading/importing:
JS
In JS you need to explicitly import the builtin modules and APIs that you want to use:
Scope of VU code
Lua
VUs execute the script from top to bottom over and over:
JS
VUs execute the global scope (aka “init code”) once to initialize, and then executes the “main function” (
export default function
) over and over:Converting Lua APIs to JS APIs
Client sleep/think time
To have a VU sleep or think for a specific amount of time (in the example below for 3 seconds), pausing the VU execution, you would write Lua code like this:
the equivalent in JS would be:
Making requests
To make HTTP requests there are a number of different Lua APIs available. In the end they’re all wrappers around the
http.request_batch()
API. Here are the common ways to make requests in Lua code:the equivalent in JS would be:
See the HTTP API docs for k6 for more information and examples.
Group requests and logic into transactions/pages
In the 3.0 product there’s a concept of pages. Lua code in between calls to
http.page_start()
and http.page_end()
will be be measured to provide a page load times in the results:the equivalent in JS would be to use
Groups
:Data store
In the 3.0 product there’s a concept of a Datastore. A CSV file that you can upload to the service and then attach to your user scenario for accessing and using the data in your user scenario logic.

Custom metrics
Beyond the standard metrics collected by the 3.0 product you can also collect custom metrics using the
results.custom_metric()
API:the equivalent in JS would be to use the
Trend
custom metric:For more information, see our docs on custom metrics (Additional metrics for
Counter
, Gauge
and Rate
are available beyond the Trend

So, I hate Lua. Like, a lot.My goal, of course, is to never write it again. Let's write JavaScript instead. Thus, zekesonxx/pinecone.
Pinecone is a JS->Lua converter that supports a decent portion of JavaScript. There's still a ton of unsupported things, but it's a start.
Unlike a lot of language converters, this isn't based on regular expressions. Instead, pinecone uses an awesome project called acorn to generate an AST (Abstract Syntax Tree), which is then converted into Lua using a lot of switch statements. This means it's very resilient against lots of weird issues that could arise.
Currently the code is very badly organized and badly commented, however it does work. You need a try.js file in the directory of the code, then to convert the code inside the try.js file, run (with Node.js and deps installed):
To then try it in Lua:

A side-effect of using an AST is that existing formatting and comments get removed. I have a plan on how to get comments back, and smart formatting is done automatically with two spaces (will later be configurable).
The obvious eventual goal is to successfully compile itself and acorn, and then do that with the Lua versions. But, more realistically, the next goals are to reorganize the codebase and start delving into the more complicated conversions (I'm eyeing switches and for loops)
So yeah, feel free to try it out and play with it. It's MIT licensed, enjoy.
