no-link-to-tagname

The builtin LinkTo component generates an <a> element. Since it is still built on top of Ember.Component it is possible to assign a tagName from the outside to change that <a> element into something else. This goes against several a11y rules though, because elements that link somewhere should be links, which have to be represented by <a> elements.

This rule looks for LinkTo component invocations where a custom tagName is assigned and warns about them.

Examples

This rule forbids the following:

<LinkTo @route="routeName" @tagName="button">Link text</LinkTo>

{{#link-to "routeName" tagName="button"}}Link text{{/link-to}}

{{link-to "Link text" "routeName" tagName="button"}}

This rule allows the following:

<LinkTo @route="routeName">Link text</LinkTo>

{{#link-to "routeName"}}Link text{{/link-to}}

{{link-to "Link text" "routeName"}}

Migration

• Remove the tagName overrides and, if you need it, adjust the styling of the <a> elements to make them look like buttons
