7. Simple pages and SEO-related pages use Go HTML Template render to generate static Fomantic-UI HTML output. Complex pages can use Vue2 (or Vue3 in future).
### Framework Usage
Mixing different frameworks together is highly discouraged. A JavaScript module should follow one major framework and follow the framework's best practice.
Recommended implementations:
* Vue + Native
* Fomantic-UI (jQuery)
* Native only
Discouraged implementations:
* Vue + jQuery
* jQuery + Native
### `async` Functions
Only mark a function as `async` if and only if there are `await` calls

### HTML Attributes and `dataset`
We forbid `dataset` usage, its camel-casing behaviour makes it hard to grep for attributes. However there are still some special cases, so the current guideline is:
* For legacy code:
* `$.data()` should be refactored to `$.attr()`.
* `$.data()` can be used to bind some non-string data to elements in rare cases, but it is highly discouraged.
* For new code:
* `node.dataset` should not be used, use `node.getAttribute` instead.
* never bind any user data to a DOM node, use a suitable design pattern to describe the relation between node and data.
### Vue2/Vue3 and JSX
Gitea is using Vue2 now, we plan to upgrade to Vue3. We decided not to introduce JSX to keep the HTML and the JavaScript code separated.
