Configuration
ESLint React provides the following configurations:
Settings
importSource
(type: string
, default: "react"
)
The source where React is imported from.
This allows to specify a custom import location for React when not using the official distribution (e.g. @pika/react
, etc).
jsxPragma
(type: string
, default: "createElement"
)
The identifier that’s used for JSX Element creation.
This should not be a member expression (i.e. use "createElement"
instead of "React.createElement"
).
jsxPragmaFrag
(type: string
, default: "Fragment"
)
The identifier that’s used for JSX fragment elements.
This should not be a member expression (i.e. use "Fragment"
instead of "React.Fragment"
).
version
(type: string
, default: "detect"
)
React version to use, "detect"
means auto detect React version from the project’s dependencies.
If importSource
is specified, an equivalent version of React should be provided here.
additionalHooks
(type: [key: string]: string[]
, default: {}
)
A object of aliases for React built-in hooks. ESLint React will recognize these aliases as equivalent to the built-in hooks in all its rules.
This is intended to cover edge cases. We suggest to use this option very sparingly, if at all.
(e.g. { useLayoutEffect: ["useIsomorphicLayoutEffect"] }
).
additionalComponents
(experimental)
An array of user-defined components, used to inform the ESLint React plugins how to treat these components during checks.
This is intended to cover edge cases. We suggest to use this option very sparingly, if at all.
