## 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:
```shell
$ 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
```shell
$ npm install --global har-to-k6
```
### Docker
```shell
$ docker pull grafana/har-to-k6:latest
```
## Usage
### CLI Usage
#### Npx
```shell
$ npx har-to-k6 archive.har -o my-k6-script.js
```
#### From `node_modules`
```shell
$ ./node_modules/.bin/har-to-k6 archive.har -o my-k6-script.js
```
#### Global
```shell
$ har-to-k6 archive.har -o my-k6-script.js
```
#### Docker
```shell
$ docker run grafana/har-to-k6:latest archive.har > my-k6-script.js
```
### Programmatic Usage
#### Converting
```js
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.
```js
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
```javascript
import { liHARToK6Script } from "har-to-k6";
```
#### CommonJS style
```javascript
const { liHARToK6Script } = require("har-to-k6");
```
#### Using a `<script>` tag
Load `standalone.js` into your HTML page:
```html
<html>
<head>
<title>HAR Converter</title>
<script src="standalone.js"></script>
<script src="index.js"></script>
</head>
</html>
```
#### Example
The API is available:
```js
async function run () {
const archive = readArchive();
harToK6.validate(archive);
const { main } = await harToK6.liHARToK6Script(archive);
displayResult(main);
}
```
