Disallow invalid v-if directives (no-invalid-v-if)

This rule checks whether every v-if directive is valid.

📖 Rule Details

This rule reports v-if directives in the following cases:

• The directive has that argument. E.g. <div v-if:aaa="foo"></div>
• The directive has that modifier. E.g. <div v-if.bbb="foo"></div>
• The directive does not have that attribute value. E.g. <div v-if></div>
• The directive is on the elements which have v-else/v-else-if directives. E.g. <div v-else v-if="foo"></div>

This rule does not check syntax errors in directives because it's checked by no-parsing-error rule.
