+# ember/template-attribute-order

+
+Enforces a consistent ordering of attributes in template elements. This helps improve readability and maintainability of templates.
+
+## Rule Details
+
+This rule enforces a consistent order for attributes on template elements. By default, it follows this order:
+
+1. `class`
+2. `id`
+3. `role`
+4. `aria-*` attributes
+5. `data-test-*` attributes
+6. `type`
+7. `name`
+8. `value`
+9. `placeholder`
+10. `disabled`
+
+## Examples
+
+Examples of **incorrect** code for this rule:
+
+```gjs
+<template>
+  <div id="main" class="container"></div>
+</template>
+```
+
+```gjs
+<template>
+  <button aria-label="Submit" role="button">Send</button>
+</template>
+```
+
+Examples of **correct** code for this rule:
+
+```gjs
+<template>
+  <div class="container" id="main"></div>
+</template>
+```
+
+```gjs
+<template>
+  <button class="btn" role="button" aria-label="Submit">Send</button>
+</template>
+```
+
+## Configuration
+
+You can customize the order by providing an `order` array:
+
+```js
+module.exports = {
+  rules: {
+    'ember/template-attribute-order': [
+      'error',
+      {
+        order: ['class', 'id', 'role', 'aria-', 'type'],
+      },
+    ],
+  },
+};
+```

+
+<!-- end auto-generated rule header -->
+
+✅ The `extends: 'recommended'` property in a configuration file enables this rule.
+
+The builtin `Input` component has several arguments that match attributes
+of the lower-case `input` HTML element. These arguments should be set via e.g.
+`@type`, instead of `type`, but it is easy to forget and can cause subtle
+issues.
+
+This rule warns about `Input` component invocations that use the following attributes instead of arguments:
+
+- `checked`
+- `type`
+- `value`
+
+The builtin `Textarea` component has several arguments that match properties
+of the lower-case `textarea` HTML element. These arguments should be set via e.g.
+`@value`, instead of `value`, but it is easy to forget and can cause subtle
+issues.
+
+This rule warns about `Textarea` component invocations that use the following attributes instead of arguments:
+
+- `value`
+
+Please note that this rule currently only warns about these three attributes on
+the `Input`, and one property on the `Textarea` components, but might be extended in the future to also warn about
+other attributes or builtin components.
+
+## Examples
+
+This rule **forbids** the following:
+
+```hbs
+<Input type='text' size='10' />
+```
+
+```hbs
+<Input @type='checkbox' checked />
+```
+
+```hbs
+<Textarea value="Hello, Tom!" /></Textarea>
+```
+
+This rule **allows** the following:
+
+```hbs
+<input type='text' size='10' />
+```
+
+```hbs
+<Input @type='text' size='10' />
+```
+
+```hbs
+<Input @type='checkbox' @checked={{true}} />
+```
+
+```hbs
+<Textarea @value="Hello, Tom!" /></Textarea>
+```
+
+## Migration
+
+- Add the `@` character in front of the relevant attributes to convert them
+  into component argument

+
+Disallows the inline form of the `link-to` component and enforces the block form instead.
+
+Ember's `link-to` component has both an inline form and a block form. This rule forbids the inline form.
+
+## Examples
+
+This rule **forbids** the following (inline form):
+
+```hbs
+{{link-to 'Link text' 'routeName' prop1 prop2}}
+```
+
+This rule **allows** the following (block form):
+
+```hbs
+{{#link-to 'routeName' prop1 prop2}}Link text{{/link-to}}
+```
+
+## Rationale
+
+The block form is a little longer but has advantages over the inline form:
+
+- It maps closer to the use of HTML anchor tags which wrap their inner content.
+- It provides an obvious way for developers to put nested markup and components inside of their link.
+- The block form's argument order is more direct: "link to route". The inline form's argument order is somewhat ambiguous (link text then link target). This is opposite of the order in HTML (`href` then link text).

+
+Requires `href` attribute on `<a>` elements.
+
+Anchor elements should have an `href` attribute to be properly recognized as links by browsers and assistive technologies. If an element is meant to be interactive but not navigate, use a `<button>` instead.
+
+## Rule Details
+
+This rule ensures that all `<a>` elements have an `href` attribute.
+
+## Examples
+
+Examples of **incorrect** code for this rule:
+
+```gjs
+<template>
+  <a>Link</a>
+</template>
+```
+
+```gjs
+<template>

+</template>
+```
+
+```gjs
+<template>
+  <a role="button">Action</a>
+</template>
+```
+
+Examples of **correct** code for this rule:

+Requires dasherized names for modifiers.
+
+Modifiers should use dasherized names when being invoked, not camelCase. This is a stylistic rule that will prevent you from using camelCase modifiers, requiring you to use dasherized modifier names instead.
+
+## Examples

+This rule **forbids** the following:

+```
+
+```hbs
+<div {{onFocus}}></div>

+This rule **allows** the following:
