Introduce htmx and use it to avoid full page load on Subscribe and Follow (#28908)
- Closes #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 ![errors](https://github.com/go-gitea/gitea/assets/20454870/181a1beb-1cb8-4858-abe8-fa1fc3f5b8f3) ## 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 ![subscribe_before](https://github.com/go-gitea/gitea/assets/20454870/cb2439a2-c3c0-425c-8d3c-5d646b1cdc28) ### After ![subscribe_after](https://github.com/go-gitea/gitea/assets/20454870/6fcd77d8-7b11-40b0-af4f-b152aaad787c) ## 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 ![follow_before](https://github.com/go-gitea/gitea/assets/20454870/a210b643-6e74-4ff9-8e61-d658c62edf1f) ### After ![follow_after](https://github.com/go-gitea/gitea/assets/20454870/5bb19ae9-0d59-4ae3-b538-4c83334e4722) --------- Signed-off-by: Yarden Shoham <[email protected]> Co-authored-by: 6543 <[email protected]> Co-authored-by: Giteabot <[email protected]>
