DEV: form-kit This PR introduces FormKit, a component-based form library designed to simplify form creation and management. This library provides a single `Form` component, various field components, controls, validation mechanisms, and customization options. Additionally, it includes helpers to facilitate testing and writing specifications for forms. 1. **Form Component**: - The main component that encapsulates form logic and structure. - Yields various utilities like `Field`, `Submit`, `Alert`, etc. **Example Usage**: ```gjs import Form from "discourse/form"; <template> <Form as |form|> <form.Field @name="username" @title="Username" @validation="required" as |field| > <field.Input /> </form.Field> <form.Field @name="age" @title="Age" as |field|> <field.Input @type="number" /> </form.Field> <form.Submit /> </Form> </template> ``` 2. **Validation**: - Built-in validation rules such as `required`, `number`, `length`, and `url`. - Custom validation callbacks for more complex validation logic. **Example Usage**: ```javascript validateUsername(name, value, data, { addError }) { if (data.bar / 2 === value) { addError(name, "That's not how maths work."); } } ``` ```hbs <form.Field @name="username" @validate={{this.validateUsername}} /> ``` 3. **Customization**: - Plugin outlets for extending form functionality. - Styling capabilities through propagated attributes. - Custom controls with properties provided by `form` and `field`. **Example Usage**: ```hbs <Form class="my-form" as |form|> <form.Field class="my-field" as |field|> <MyCustomControl id={{field.id}} @onChange={{field.set}} /> </form.Field> </Form> ``` 4. **Helpers for Testing**: - Test assertions for form and field validation. **Example usage**: ```javascript assert.form().hasErrors("the form shows errors"); assert.form().field("foo").hasValue("bar", "user has set the value"); ``` - Helper for interacting with he form **Example usage**: ```javascript await formKit().field("foo").fillIn("bar"); ``` 5. **Page Object for System Specs**: - Page objects for interacting with forms in system specs. - Methods for submitting forms, checking alerts, and interacting with fields. **Example Usage**: ```ruby form = PageObjects::Components::FormKit.new(".my-form") form.submit expect(form).to have_an_alert("message") ``` **Field Interactions**: ```ruby field = form.field("foo") expect(field).to have_value("bar") field.fill_in("bar") ``` 6. **Collections handling**: - A specific component to handle array of objects **Example Usage**: ```gjs <Form @data={{hash foo=(array (hash bar=1) (hash bar=2))}} as |form|> <form.Collection @name="foo" as |collection|> <collection.Field @name="bar" @title="Bar" as |field|> <field.Input /> </collection.Field> </form.Collection> </Form> ```
