Installation

Local Installation (recommended)

While possible to install globally, we recommend that you, if possible, add the converter to the node_modules of your test project using:

$ npm install --save har-to-k6

Note that this will require you to run the converter with npx har-to-k6 your-har-file or, if you are using an older version of npm, ./node_modules/.bin/har-to-k6 your-har-file`.

Global Installation

$ npm install --global har-to-k6

Docker

$ docker pull grafana/har-to-k6:latest

Usage

CLI Usage

Npx

$ npx har-to-k6 archive.har -o my-k6-script.js

From `node_modules`

$ ./node_modules/.bin/har-to-k6 archive.har -o my-k6-script.js

Global

$ har-to-k6 archive.har -o my-k6-script.js

Programmatic Usage

Converting

const fs = require("fs");
const { liHARToK6Script } = require("har-to-k6");

async function run () {
  const archive = readArchive();
  const { main } = await liHARToK6Script(archive);
  fs.writeFileSync("./load-test.js", main);
}

Validating

Use validate() to run validation alone. Returns without error for a valid archive. Throws InvalidArchiveError for validation failure.

const { InvalidArchiveError, validate } = require("har-to-k6");

const archive = readArchive();
try {
  validate(archive);
} catch (error) {
  if (error instanceof InvalidArchiveError) {
    // Handle invalid archive
  } else {
    throw error;
  }
}

Browser Usage

har-to-k6 can be ran in the browser. This exposes the standard API under harToK6.

Importing as ES module

import { liHARToK6Script } from "har-to-k6";

CommonJS style

const { liHARToK6Script } = require("har-to-k6");

Using a `<script>` tag

Load standalone.js into your HTML page:

<html>
  <head>
    <title>HAR Converter</title>
    <script src="standalone.js"></script>
    <script src="index.js"></script>
  </head>
</html>

Example

The API is available:

async function run () {
    const archive = readArchive();
    harToK6.validate(archive);
    const { main } = await harToK6.liHARToK6Script(archive);
    displayResult(main);
}
