HTML Templating Engine

Package ace provides an HTML template engine.

Package mailyak provides a simple interface for generating MIME compliant emails, and optionally sending them over SMTP. Both plain-text and HTML email body content is supported, and their types implement io.Writer allowing easy composition directly from templating engines, etc. Attachments are fully supported including inline attachments, with anything that implements io.Reader suitable as a source (like files on disk, in-memory buffers, etc). The raw MIME content can be retrieved using MimeBuf(), typically used with an API service such as Amazon SES that does not require using an SMTP interface. MailYak supports both plain-text SMTP (which is automatically upgraded to a secure connection with STARTTLS if supported by the SMTP server) and explicit TLS connections.

For convenience the HTML and Plain methods return a type implementing io.Writer, allowing email bodies to be composed directly from templating engines.

Package kyoto was made for creating fast, server side frontend avoiding vanilla templating downsides. It tries to address complexities in frontend domain like responsibility separation, components structure, asynchronous load and hassle-free dynamic layout updates. These issues are common for frontends written with Go. The library provides you with primitives for pages and components creation, state and rendering management, dynamic layout updates (with external packages integration), utility functions and asynchronous components out of the box. Still, it bundles with minimal dependencies and tries to utilize built-ins as much as possible. You would probably want to opt out from this library in few cases, like, if you're not ready for drastic API changes between major version, you want to develop SPA/PWA and/or complex client-side logic, or you're just feeling OK with your current setup. Please, don't compare kyoto with a popular JS libraries like React, Vue or Svelte. I know you will have such a desire, but most likely you will be wrong. Use cases and underlying principles are just too different. If you want to get an idea of what a typical static component would look like, here's some sample code. It's very ascetic and simplistic, as we don't want to overload you with implementation details. Markup is also not included here (it's just a well-known `html/template`). For details, please check project's website on https://kyoto.codes. Also, you may check the library index to explore available sub-packages and https://pkg.go.dev for Go'ish documentation style. We don't want you to deal with boilerplate code on your own, so you can proceed with our simple starter project. Feel free to use it as an example for your own setup. Components is a common approach for modern libraries to manage frontend parts. Kyoto's components are trying to be mostly independent (but configurable) part of the project. To create component, it would be enough to implement component.Component. It's a function, a context receiver which returns a component state. State is an implementation of component.State, which is easy to implement with nesting one of the state implementations (options will be described later). Each component becomes a part of the page or top-level component, which executes component function asynchronously and gets a state future object. In that way your components are executing in a non-blocking way. Pages are just top-level components, where you can configure rendering and page related stuff. Stateful components are pretty similar to stateless ones, but they are actually implementing marshal/unmarshal interface instead of mocking it. You have multiple state options to choose from: universal or server. Universal state is a state, that can be marshalled and unmarshalled both on server and client. It's a common state option without functionality limitations. On the other hand, the whole state must be sent and received, which applies some limitations on the state size. Server state can be marshalled and unmarshalled only on server. It's a good option for components, that are not supposed to be updated on client side (f.e. no inputs). Also, it's a good option for components with lots of state data. Sometimes you may want to pass some arguments to the component. It's easy to do with wrapping component with additional function. You have an access to the context inside the component. It includes request and response objects, as well as some other useful stuff like store. This library doesn't provide you with routing out of the box. You can use any router you want, built-in one is not a bad option for basic needs. Rendering might be tricky, but we're trying to make it as simple as possible. By default, we're using `html/template` as a rendering engine. It's a well-known built-in package, so you don't have to learn anything new. Out of the box we're parsing all templates in root directory with `*.html` glob. You can change this behavior with `TEMPLATE_GLOB` global variable. Don't rely on file names while working with template names, use `define` entry for each your component. To provide your components with ability to be rendered, you have to do some basic steps. First, you have to nest one of the rendering implementations into your component state (f.e. `rendering.Template`). You can customize rendering with providing values to the rendering implementation. If you need to modify these values for the entire project, we recommend looking at the global settings or creating a builder function for rendering object. By default, render handler will use a component name as a template name. So, you have to define a template with the same name as your component (not the filename, but "define" entry). That's enough to be rendered by `rendering.Handler`. For rendering a nested component, use built-in `template` function. Provide a resolved future object as a template argument in this way. Nested components are not obligated to have rendering implementation if you're using them in this way. As an alternative, you can nest rendering implementation (e.g. `rendering.Template`) into your nested component. In this way you can use `render` function to simplify your code. Please, don't use this approach heavily now, as it affects rendering performance. HTMX is a frontend library, that allows you to update your page layout dynamically. It perfectly fits into kyoto, which focuses on components and server side rendering. Thanks to the component structure, there is no need to define separate rendering logic specially for HTMX. Please, check https://htmx.org/docs/#installing for installation instructions. In addition to this, you must register HTMX handlers for your dynamic components. This is a basic example of HTMX usage. Please, check https://htmx.org/docs/ for more details. In this example we're defining a form component, that is updating itself on submit. And this is how you can define a component, that will handle this request. Sometimes it might be useful to have a component state, which will persist between requests and will be stored without any actual usage in the client side presentation. This function injects a hidden input field with a serialized state. Let's check how it works on the server side. As a result, we have a component with a persistent state between requests.

Package smash - Golang Templating Engine. Golang templating is fast and great for rendering html templates, but differs from other templating engines. Smash takes away some of the more complex configurations and restrictions. It is a simple wrapper around the Golang html/template package and is based on the Django templating syntax. Serving static files is easy, see the example below.
