Ah yeah. The only documentation we reference that I can find is [virtual-dom/virtual-hyperscript/README.md at master · Matt-Esch/virtual-dom · GitHub](https://github.com/Matt-Esch/virtual-dom/blob/master/virtual-hyperscript/README.md) and it’s sort of hidden in our codebase as a comment 🙂 Even with that I couldn’t find the answer you are looking for there. In any case, there is a topic here on Meta that does have the solution:

> [@Widget Helper stripping attributes?](https://meta.discourse.org/t/widget-helper-stripping-attributes/68014/2):

So based on the code you provided, it should work if you change it to the following:

```js
h("script", { src: "http://localhost:5000/pass.js", attributes: { "data-space": "123" } }),

```
