Introduce htmx and use it to avoid full page load on `Subscribe` and `Follow` (#28908)
- Closes https://github.com/go-gitea/gitea/issues/28880 This change introduces htmx with the hope we could use it to make Gitea more reactive while keeping our "HTML rendered on the server" approach. - Add `htmx.js` that imports `htmx.org` and initializes error toasts - Place `hx-headers='{"x-csrf-token": "{{.CsrfToken}}"}'` on the `<body>` tag so every request that htmx sends is authenticated - Place `hx-swap="outerHTML"` on the `<body>` tag so the response of each htmx request replaces the tag it targets (as opposed to its inner content) - Place `hx-push-url="false"` on the `<body>` tag so no changes to the URL happen in `<form>` tags - Add the `is-loading` class during request ### Error toasts in action  ## Don't do a full page load when clicking the subscribe button - Refactor the form around the subscribe button into its own template - Use htmx to perform the form submission - `hx-boost="true"` to prevent the default form submission behavior of a full page load - `hx-sync="this:replace"` to replace the current request (in case the button is clicked again before the response is returned) - `hx-target="this"` to replace the form tag with the new form tag - Change the backend response to return a `<form>` tag instead of a redirect to the issue page ### Before  ### After  ## Don't do a full page load when clicking the follow button - Use htmx to perform the button request - `hx-post="{{.ContextUser.HomeLink}}?action=follow"` to send a POST request to follow the user - `hx-target="#profile-avatar-card"` to target the card div for replacement - `hx-indicator="#profile-avatar-card"` to place the loading indicator on the card - Change the backend response to return a `<div>` tag (the card) instead of a redirect to the user page ### Before  ### After  --------- Signed-off-by: Yarden Shoham <git@yardenshoham.com> Co-authored-by: 6543 <m.huber@kithara.com> Co-authored-by: Giteabot <teabot@gitea.io>pull/28987/head
