Components

Formulas

Rule Severity Auto fixes Description
Project formulas with no references Warning Delete the formula Project formulas that are not referenced anywhere in your project can lead to confusion and bloated projects. Nordcraft flags these unused formulas to help you keep your project clean and efficient.
Unknown project formula reference Error No Finds references to project formulas that do not exist. This helps you identify and correct broken references in your project.
Legacy formula Warning Replace formula Finds known legacy formulas that should no longer be used.
Component formulas with no reference Warning No Finds component formulas that are not used by any other formulas in a component.
Unknown component formula input Warning No Finds invalid component formula inputs.
Unknown project formula input Warning No Finds invalid project formula inputs.
Unknown component formula reference Warning No Finds references to unknown component formulas.
Unknown repeat index formula Warning No Finds usage of repeat index formulas that are not within a valid repeat context.
Unknown repeat item formula Warning No Finds usage of repeat item formulas that are not within a valid repeat context.

Actions

Rule Severity Auto fixes Description
Project actions with no references Warning Delete the action Project actions that are not referenced anywhere in your project can lead to confusion and bloated projects. This rule flags unused project actions to help keep project clean and efficient.
Unknown project action references Warning No Finds references to project actions that do not exist. This helps identify and correct broken references in projects.
Legacy action Warning Replace the action Finds known legacy actions that should no longer be used.
No console Info No Detects usage of the Log to console action in workflows. While useful for debugging, leaving console logs in production code can lead to performance issues and cluttered output.

Variables

Rule Severity Auto fixes Description
Variables with no references Warning Delete the variable Variables that are not referenced anywhere in a component have no effect/value and can safely be removed.
Unknown variable references Error No Finds references to variables that do not exist. This helps identify and correct broken references in components.
Unknown variable setter Warning No Trying to set a variable that doesn't exist will have no effect, but usually highlights an issue in the logic for a component.

Attributes

Rule Severity Auto fixes Description
Attributes with no references Warning Delete the attribute Attributes that are not referenced anywhere in a component are not needed and can be removed.
Unknown attribute reference Error No Finds references to attributes that do not exist in a component. This helps you identify and correct broken references in your project.
Unknown component attribute Error Delete the component attribute Identifies attributes on component nodes that don't exist on the target component. These invalid attributes can safely be removed.

Events

Rule Severity Auto fixes Description
Duplicate event trigger Warning No Flags duplicate event triggers on an element or component node. This usually happens in legacy projects.
Events with no references Warning Delete the event Finds events in a component that are never triggered. These events can be removed to keep the component clean and efficient.
Unknown event Error No Flags events declared on component nodes that don't exist in the target component.
Unknown event trigger Error No Finds event triggers in components that don't match any of the declared events in the component.

APIs

Rule Severity Auto fixes Description
APIs with no references Warning Delete the API API that are never referenced in their component are usually not needed and can be removed.
Unknown API Error No Finds references to unknown APIs.
Legacy API Warning No Finds APIs that could be upgraded to the newer API v2 format. This conversion can be done from within the Nordcraft editor.
Invalid parser mode Warning No Flags if an invalid parser mode is used in combination with SSR. The valid parser modes when fetching APIs during SSR are: json, text, and auto.
Invalid proxy body Warning No Flags if an API is set to use templates (for cookie injection) in the body, but the API is not proxied.
Invalid proxy cookie Warning No Flags APIs that are not proxied but are using a Get Http-Only Cookie formula. The template replacement will only work in the Nordcraft API proxy.
API inputs with no references Warning No API inputs that are not used in the API (for headers, body etc.) are not needed.
Unknown API Input Error No Finds references to unknown/invalid API inputs.
Unused API services Warning Delete the API service API services that are never used by any API can safely be removed.
Unknown API service Warning No Flags APIs that reference unknown API services. This means the API doesn't benefit from the schema provided by the API service and could indicate that a service was deleted by accident.

Context

Rule Severity Auto fixes Description
No context consumption possible Warning No Flags components that expose formulas or workflows in context, but don't have a slot element or a component as a child. This would mean that it was not possible for other components/elements to consume the context formulas/workflows.
Unknown context formula Error No Finds references to unknown context formulas. This could happen if a context provider no longer had a formula by the name declared in the context consumer's reference.
Unknown context provider formula Error No Finds references to un-exposed context formulas. This could happen if a context formula had previously been exposed in context, but was now no longer exposed.
Unknown context provider Error No Finds references to context providers (components) that don't exist in the project.

Style

Rule Severity Auto fixes Description
Invalid style syntax Error Delete the style property Finds invalid style properties/syntax on elements and components.
Unknown classname Error No Flags style variants that reference unknown classnames on an element.

Slots

Rule Severity Auto fixes Description
Unknown component slot Error No Flags slotted elements/components that reference an unknown slot in the host component.

DOM

Rule Severity Auto fixes Description
Required direct child Warning No Flags elements that have an invalid direct child element. For instance, a <ul> element can only have li, script or template elements as children.
Required direct parent Warning No Flags elements that have an invalid direct parent element. For instance, a <li> element can only be a child of ul or ol elements.
Required element attribute Warning No Flags elements that are missing required attributes. For instance, an <img> element must have a src attribute.
Required meta tag Warning No Flags pages that have not declared a title or description meta tag.
Invalid interactive content Warning No Flags elements that are not allowed to include interactive content elements, but include one or more in their children.
Image without dimension Warning No Flags <img> elements that do not have width, height or aspect-ratio attributes specified.
Non-empty void elements Warning No Flags void elements that have children declared.

Logic

Rule Severity Auto fixes Description
No static nodes Warning Delete condition | Delete node Flags elements that have a Show formula, but where the formula always evaluates to true or false.
Unnecessary "And" formula Warning No Finds And formulas where one of its conditions is always falsy. This means that the And formula is always falsy.
Unnecessary "Or" formula Warning No Finds Or formulas where one of its conditions is always truthy. This means that the Or formula is always truthy.

Routing

Rule Severity Auto fixes Description
Duplicate routes Warning No Flags pages that have duplicate route declarations (where the path parameters match).
Duplicate url parameter Warning No Flags if a query parameter and a path parameter have the same name.
Unknown set url parameter (legacy) Warning No Finds actions that try to set a url parameter (path or query) that does not exist.
Unknown set url parameters Warning No Finds actions that try to set one or multiple url parameters (path or query) that do not exist.
Unknown url parameter Error No Finds references to url parameters that do not exist.

Miscellaneous

Rule Severity Auto fixes Description
Node with no references Warning Delete the orphan node Finds nodes/elements that are not included by any other node/element. This can happen during copy/paste.
Require browser extension Info No Highlights if the Nordcraft browser extension is not installed, but the project is setting/adding cookies in actions.
Unknown cookie Info No Flags cookies referenced by the Get Http-Only Cookie formula that are not found by the Nordcraft browser extension.
