| Rule | Description | ✅ | 🔧 | 💡 |
|---|---|---|---|---|
contextual-lifecycle |
Ensures that lifecycle methods are used in a correct context | ✅ | ||
no-async-lifecycle-method |
Angular Lifecycle methods should not be async. Angular does not wait for async lifecycle but the code incorrectly suggests it does. | |||
no-attribute-decorator |
The @Attribute decorator is used to obtain a single value for an attribute. This is a much less common use-case than getting a stream of values (using @Input), so often the @Attribute decorator is mistakenly used when @Input was what was intended. This rule disallows usage of @Attribute decorator altogether in order to prevent these mistakes. | |||
require-lifecycle-on-prototype |
Ensures that lifecycle methods are defined on the object's prototype instead of on an instance. | |||
sort-lifecycle-methods |
Ensures that lifecycle methods are declared in order of execution |
