Use `jetzig server` or `zig build -Ddebug_console=true run` to launch a
development server with the debug console enabled.
When an error is encountered a formatted stack trace is dumped to the
browser along with the current response data. Both outputs are
syntax-highlighted using Prism JS.
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.
Define `pub const Global = SomeType` at top level in `src/main.zig`,
then create a pointer to `SomeType` and pass to `app.start`:
```
app.start(routes, .{ .global = global });
```
Then access in a view as `request.global`.
Use `request.file("form-field-name")` to try to find a multipart-encoded
form value for the given name. Returns `jetzig.http.File` if a match is
found which provides `content` (uploaded file content) and `filename`
(filename as passed by browser).
Add `jetzig test` command which runs build step `jetzig:test`.
Add `jetzig.testing` namespace which provides test helpers and a test
app.
Add tests to view generator (i.e. include tests for generated routes).
Allow middleware to resolve a request by calling `request.redirect` or
`request.render` - after this point, the request stops processing and
renders immediately.
Permit setting template during view render with `request.setTemplate()`
Permit middleware to define custom routes to static content with
`pub const Routes` (implemented for something no longer needed but seems
useful anyway).
Implement globbing on custom routes, `/foo/:bar*` will glob all path
segments including and after `/foo/...`, e.g. `/foo/bar/baz/qux` will
pass invoke the custom view function with an array of `bar`, `baz`,
`qux` as first argument (instead of typical resource ID).
In `main()`:
```zig
app.route(.GET, "/custom/:id/foo/bar", @import("app/views/custom/foo.zig"), .bar);
```
Routes `GET` request with path (e.g.) `/custom/1234/foo/bar` to `bar()`
defined in `src/app/views/custom/foo.zig`.
Routes with an `:id` segment expect a function with three parameters,
routes without an `:id` segment expect a function with two parameters
(i.e. the same as `get` vs `index`).
Use Karl Seguin's http.zig as HTTP server backend:
https://github.com/karlseguin/http.zig
Update loggers to use new `jetzig.loggers.LogQueue` to offload logging
to a background thread.
Numerous other optimizations to remove unneeded allocs.
Performance jump on a simple request from approx. 2k requests/second to
approx. 40k requests/second (Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz).
Color support for Windows
Zmpl partial arg type coercion
Create mailers with `jetzig generate mailer <name>`. Mailers define
default values for email fields (e.g. subject, from address, etc.).
Mailers use Zmpl for rendering text/HTML parts.
Send an email from a request with `request.mail()`. Call
`deliver(.background, .{})` on the return value to use the built-in
mail job to send the email asynchronously.
Improve query/HTTP request body param parsing - unescape `+` and `%XX`
characters.
Use in-memory KV store (JetKV) for simple job queue.
Build script generates an array of Zig modules in `src/app/jobs/` and
stores their name + run function (`run(allocator, params, logger)`).
View functions schedule jobs with arbitrary params.
Thread pool spawns a (configurable) number of workers and pops jobs from
the queue, then invokes the appropriate run function.
Generate an array of `jetzig.views.Route` in `GenerateRoutes.zig` exe
instead of a meta-route that we later translate into an actual route.
This makes things much simpler for static routes at build time and
dynamic routes at run time as we no longer need to use comptime - we
just have an array of routes ready-made.
When `HX-Target` header is present, bypass any configured layout for the
request. This allows a full page reload to render with a layout, i.e.
render the entire page, while a request from htmx will load just the
content directly generated by the view.
`root_path` is cruft from previous route/template matching mechanism.
Caused failure when running binary in isolation: binary can now run
independently without any dependency on file system other than:
```
* public/ <-- should always be separate to allow e.g. serving directly
via nginx
* static/ <-- later will be compiled into binary
```
Latest Zmpl provides `template.renderWithLayout(other_template, data)`,
allowing a template to be renedered within another template.
Create layouts in `src/app/views/layouts/` or use
`jetzig generate layout [name]` and set `pub const layout = "name";` in
each view file.
Views are copied to zig-cache, meaning that any files in `src/` are not
available for `@import` by default. Copy all .zig files from `src/` into
zig-cache so that relative imports work as expected. This also removes
the need to specifically copy views into zig-cache as the full tree is
now present.
Also fix a bug in static route fallback - remove superfluous underscore
so static routes with non-matching params render default HTML/JSON
content.
Andrew overhauled std.http to avoid allocations and put control of
connection + stream into hands of users. For now, do a barebones
implementation to restore compatibility, later we can do keepalive and
pipelining. For now, still getting decent enough performance the "slow"
way.

> actually being used as the request.

> Now, it looks like this:
> 1. std.net.Server.accept() gives you a std.net.Server.Connection
> 2. std.http.Server.init() with the connection
> 3. Server.receiveHead() gives you a Request
> 4. Request.reader() gives you a body reader
> 5. Request.respond() is a one-shot, or Request.respondStreaming() creates
> a Response
> 6. Response.writer() gives you a body writer
> 7. Response.end() finishes the response; Response.endChunked() allows
> passing response trailers.
>
> In other words, the type system now guides the API user down the correct
> path.
>
> receiveHead allows extra bytes to be read into the read buffer, and then
> will reuse those bytes for the body or the next request upon connection
> reuse.
>
> respond(), the one-shot function, will send the entire response in one

>
> Streaming response bodies no longer wastefully wraps every call to write
> with a chunk header and trailer; instead it only sends the HTTP chunk
> wrapper when flushing. This means the user can still control when it
> happens but it also does not add unnecessary chunks.
>
> Empirically, in my example project that uses this API, the usage code is
> significantly less noisy, it has less error handling while handling

> Additionally:
> * Uncouple std.http.HeadParser from protocol.zig
> * Delete std.Server.Connection; use std.net.Server.Connection instead.
> - The API user supplies the read buffer when initializing the

> for reading the body into.

Implement `jetzig.http.Request.params()` which parses either a JSON
request body or a query param string into a `jetzig.data.Value`.
Allow configuring params for static site generation - configure an array
of params for each endpoint which is then parsed at build time and a
separate JSON and HTML output is generated for each by invoking the
relevant view function and passing in resource ID/params. Params are
stored in generated `routes.zig` for route matching at run time.
Generate views defined with `request: *jetzig.http.StaticRequest` as
static content into `static/` directory so that exported JSON and HTML
can be rendered direct from disk, skipping runtime rendering.
