Use JetQuery's new `Repo.bindConnect()` to get a new Repo bound to a
connection for each request. This significantly simplifies connection
management and offloads all the connection pool
management/reconnecting/etc. to pg.zig where it belongs.
Improve development mode SQL syntax highlighting - highlight `SELECT`,
`UPDATE`, `DELETE`, `INSERT` in different bolded colors for clarity.
Add to middleware in app's `src/main.zig`:
```zig
pub const jetzig_options = struct {
pub const middleware: []const type = &.{
jetzig.middleware.AntiCsrfMiddleware,
};
};
```
CSRF token available in Zmpl templates:
```
{{context.authenticityToken()}}
```
or render a hidden form element:
```
{{context.authenticityFormElement()}}
```
The following HTML requests are rejected (403 Forbidden) if the
submitted query param does not match the value stored in the encrypted
session (added automatically when the token is generated for a template
value):
* POST
* PUT
* PATCH
* DELETE
JSON requests are not impacted - users should either disable JSON
endpoints or implement a different authentication method to protect
them.
