# JSDOM + Jose => Uint8Array issue

This is a bug repro repo to demonstrate a bug when trying to combine [jose](https://github.com/panva/jose) (JWT utility) in a test environment with [JSDOM](https://github.com/jsdom/jsdom).

## About

This repo contains a piece of code to generate a signed JWT token using jose.

## Repro

This repo are setup to work by default.

First, install the project dependencies:

```bash

npm i

```

Now, you can run the following npm script:

```bash

npm run print

```

This will print the generated JWT Token.

Now, run the unit test with Vitest (no JSDOM yet):

```bash

npm run test

```

The single test will pass.

Now, go to `vitest.config.js` and enable the environment:

```diff

export default defineConfig({

  test: {

    // Uncomment the following to see the bug

-   // environment: "jsdom",

+   environment: "jsdom",

  },

});

```

Now, if you run the test script again (`npm run test`), you'll see it's broken:

```text

 FAIL  src/generate-jwt.test.js > generateJWT > should generate a JWT token

TypeError: payload must be an instance of Uint8Array

     20|     .sign(privateKey);
