react-doctor/prefer-es6-class

Use one component style consistently: ES2015 `class extends React.Component` (default) over the legacy `createReactClass` factory.

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

In its default "always" mode, fires on any CallExpression whose callee is createReactClass(...) or React.createReactClass(...): the legacy ES5 component factory. Under the opt-in "never" mode it flips to flag class X extends Component | PureComponent | React.Component | React.PureComponent instead.

Suppress when: matching is purely syntactic on the callee name, so a same-named local helper called createReactClass that has nothing to do with React's factory is still flagged; confirm the call actually resolves to the react-create-class package before acting.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Convert the createReactClass({ render() {...} }) call into an ES2015 class: class Hello extends React.Component { render() { return <div>Hello {this.props.name}</div>; } }, moving displayName to a static field and lifecycle/render methods onto the class. Better still in modern React, rewrite as a function component if the class holds no state or lifecycle logic. See https://oxc.rs/docs/guide/usage/linter/rules/react/prefer-es6-class
