You can also add more than one folder: - -```python -catalog.add_folder("myapp/layouts") -catalog.add_folder("myapp/components") -``` - -If you end up having more than one component with the same name, the one in the first folder will take priority. - -**Second**, they must have a ".jinja" extension. This also helps code editors automatically select the correct language syntax to highlight. However, you can configure it in the catalog. - -**Third**, the component name must start with an uppercase letter. Why? This is how JinjaX differentiates a component from a regular HTML tag when using it. I recommend using PascalCase names, like Python classes. - -The name of the file (minus the extension) is also how you call the component. For example, if the file is "components/PersonForm.jinja": - -``` -└ myapp/ - ├── app.py - ├── components/ - └─ PersonForm.jinja -``` - -The name of the component is "PersonForm" and can be called like this: - -From Python code or a non-component template: - -- `catalog.render("PersonForm")` - -From another component: - -- `<PersonForm> some content </PersonForm>`, or -- `<PersonForm />` - -If the component is in a subfolder, the name of that folder becomes part of its name too: - -``` -└ myapp/ - ├── app.py - ├── components/ - └─ person - └─ PersonForm.jinja -``` - -A "components/person/PersonForm.jinja" component is named "person.PersonForm", meaning the name of the subfolder and the name of the file separated by a dot. This is the full name you use to call it: - -From Python code or a non-component template: - -- `catalog.render("person.PersonForm")` - -From another component: - -- `<person.PersonForm> some content </person.PersonForm>`, or -- `<person.PersonForm />` - -Notice how the folder name doesn't need to start with an uppercase if you don't want it to. - -<a href="/static/img/anatomy-en.png" target="_blank"> - <img src="/static/img/anatomy-en.png" style="margin:0 auto;width:90%;max-width:35rem;"> -</a> - -## Taking Arguments - -More often than not, a component takes one or more arguments to render. Every argument must be declared at the beginning of the component with `{#def arg1, arg2, ... #}`. - -```html+jinja -{#def action, method="post", multipart=False #} - -<form method="{{ method }}" action="{{ action }}" - {%- if multipart %} enctype="multipart/form-data"{% endif %} -> - {{ content }} -</form> -``` - -In this example, the component takes three arguments: "action", "method", and "multipart". The last two have default values, so they are optional, but the first one doesn't. That means it must be passed a value when rendering the component. - -The syntax is exactly like how you declare the arguments of a Python function (in fact, it's parsed by the same code), so it can even include type comments, although they are not used by JinjaX (yet!). - -```python -{#def - data: dict[str, str], - method: str = "post", - multipart: bool = False -#} -... -``` - -## Passing Arguments - -There are two types of arguments: strings and expressions. - -### String - -Strings are passed like regular HTML attributes: - -```html+jinja -<Form action="/new" method="PATCH"> ... </Form> - -<Alert message="Profile updated" /> - -<Card title="Hello world" type="big"> ... </Card> -``` - -### Expressions - -There are two different but equivalent ways to pass non-string arguments: - -"Jinja-like", where you use double curly braces instead of quotes: - -```html+jinja title="Jinja-like" -<Example - columns={{ 2 }} - tabbed={{ False }} - panels={{ {'one': 'lorem', 'two': 'ipsum'} }} - class={{ 'bg-' + color }} -/> -``` - -... and "Vue-like", where you keep using quotes, but prefix the name of the attribute with a colon: - -```html+jinja title="Vue-like" -<Example - :columns="2" - :tabbed="False" - :panels="{'one': 'lorem', 'two': 'ipsum'}" - :class="'bg-' + color" -/> -``` - -<Callout type="note"> - For `True` values, you can just use the name, like in HTML: - <br> - ```html+jinja - <Example class="green" hidden /> - ``` -</Callout> - -<Callout type="note"> - You can also use dashes when passing an argument, but they will be translated to underscores: - <br> - ```html+jinja - <Example aria-label="Hi" /> - ``` - <br> - ```html+jinja title="Example.jinja" - {#def aria_label = "" #} - ... - ``` -</Callout> - -## With Content - -There is always an extra implicit argument: **the content** inside the component. Read more about it in the [next](/guide/slots) section. - -## Extra Arguments - -If you pass arguments not declared in a component, those are not discarded but rather collected in an `attrs` object. - -You then call `attrs.render()` to render the received arguments as HTML attributes. - -For example, this component: - -```html+jinja title="Card.jinja" -{#def title #} -<div {{ attrs.render() }}> - <h1>{{ title }}</h1> - {{ content }} -</div> -``` - -Called as: - -```html -<Card title="Products" class="mb-10" open>bla</Card> -``` - -Will be rendered as: - -```html -<div class="mb-10" open> - <h1>Products</h1> - bla -</div> -``` - -You can add or remove arguments before rendering them using the other methods of the `attrs` object.

You then add the path of the folder with your components to the catalog: - -```python -from jinjax import Catalog - -catalog = Catalog() -catalog.add_folder("myapp/components") -``` - -#### Render - -You will use the catalog to render components from your views. - -```python -def myview(): - ... - return catalog.render( - "Page", - title="Lorem ipsum", - message="Hello", - ) -``` - -In this example, it is a component for the whole page, but you can also render smaller components, even from inside a regular Jinja template if you add the catalog as a global: - -```python -app.jinja_env.globals["catalog"] = catalog -``` - -```html+jinja -{% block content %} -<div> - {{ catalog.irender("LikeButton", title="Like and subscribe!", post=post) }} -</div> -<p>Lorem ipsum</p> -{{ catalog.irender("CommentForm", post=post) }} -{% endblock %} -``` - -## How It Works - -JinjaX uses Jinja to render the component templates. In fact, it currently works as a pre-processor, replacing all: - -```html -<Component attr="value">content</Component> -``` - -with function calls like: - -```html+jinja -{% call catalog.irender("Component", attr="value") %}content{% endcall %} -``` - -These calls are evaluated at render time. Each call loads the source of the component file, parses it to extract the names of CSS/JS files, required and/or optional attributes, pre-processes the template (replacing components with function calls, as before), and finally renders the new template. - -### Reusing Jinja's Globals, Filters, and Tests - -You can add your own global variables and functions, filters, tests, and Jinja extensions when creating the catalog: - -```python -from jinjax import Catalog - -catalog = Catalog( - globals={ ... }, - filters={ ... }, - tests={ ... }, - extensions=[ ... ], -) -``` - -or afterward. - -```python -catalog.jinja_env.globals.update({ ... }) -catalog.jinja_env.filters.update({ ... }) -catalog.jinja_env.tests.update({ ... }) -catalog.jinja_env.extensions.extend([ ... ]) -``` - -The ["do" extension](https://jinja.palletsprojects.com/en/3.0.x/extensions/#expression-statement) is enabled by default, so you can write things like: - -```html+jinja -{% do attrs.set(class="btn", disabled=True) %} -``` - -### Reusing an Existing Jinja Environment - -You can also reuse an existing Jinja Environment, for example: - -#### Flask: - -```python -app = Flask(__name__) - -# Here we add the Flask Jinja globals, filters, etc., like `url_for()` -catalog = jinjax.Catalog(jinja_env=app.jinja_env) -``` - -#### Django: - -First, configure Jinja in `settings.py` and [jinja_env.py](https://docs.djangoproject.com/en/5.0/topics/templates/#django.template.backends.jinja2.Jinja2). - -To have a separate "components" folder for shared components and also have "components" subfolders at each Django app level: - -```python -import jinjax -from jinja2.loaders import FileSystemLoader - -def environment(loader: FileSystemLoader, **options): - env = Environment(loader=loader, **options) - - ... - - env.add_extension(jinjax.JinjaX) - catalog = jinjax.Catalog(jinja_env=env) - - catalog.add_folder("components") - for dir in loader.searchpath: - catalog.add_folder(os.path.join(dir, "components")) - - return env -``` - -#### FastAPI: - -TBD

This is needed to avoid unexpected behavior. By default, CSS transitions only occur when a property changes from one value to another on a visible element; they are not triggered on an element's first style update, or when the `display` type changes from `none` to another type. - -- `display` property - - Add `display` to the transitions list so that the popover will remain as `display:block` (or another visible `display` value) for the duration of the transition, ensuring the other transitions are visible. - -- `overlay` property - - Include `overlay` in the transitions list to ensure the removal of the popover from the top layer is deferred until the transition completes, again ensuring the transition is visible. - -- `transition-behavior` property - - Set `transition-behavior:allow-discrete` on the `display` and `overlay` transitions (or on the `transition` shorthand) to enable discrete transitions on these two properties that are not by default animatable. - -For example, let's say the styles we want to transition are `opacity` and `transform`: we want the popover to fade in or out while moving down or up. - -To achieve this, we set a starting state for these properties on the hidden state of the popover element (selected with the `[popover]` attribute selector) and an end state for the shown state of the popover (selected via the `:popover-open` pseudo-class). We also use the `transition` property to define the properties to animate and the animation's duration as the popover gets shown or hidden: - -```css -/*** Transition for the popover itself ***/ -[popover]:popover-open { - opacity: 1; - transform: scaleX(1); -} -[popover] { - transition: all 0.2s allow-discrete; - /* Final state of the exit animation */ - opacity: 0; - transform: translateY(-3rem); -} -[popover]:popover-open { - opacity: 1; - transform: translateY(0); -} -/* Needs to be after the previous [popover]:popover-open rule -to take effect, as the specificity is the same */ -@starting-style { - [popover]:popover-open { - opacity: 0; - transform: translateY(-3rem); - } -} - -/*** Transition for the popover's backdrop ***/ -[popover]::backdrop { - /* Final state of the exit animation */ - background-color: rgb(0 0 0 / 0%); - transition: all 0.2s allow-discrete; -} -[popover]:popover-open::backdrop { - background-color: rgb(0 0 0 / 15%); -} -@starting-style { - [popover]:popover-open::backdrop { - background-color: rgb(0 0 0 / 0%); - } -} -``` - -You can see a working example of this in the demo [at the beginning of the page](#startpage). - -<Callout> -Because popovers change from <code>display:none</code> to <code>display:block</code> each time they are shown, the popover transitions from its <code>@starting-style</code> styles to its <code>[popover]:popover-open</code> styles every time the entry transition occurs.
