7 years ago I use flow, so it may be related.

7 years ago @ljharb any debug flag I can turn on or any line I can add a console.log to see the filename? Couldn't find the exact file.

7 years ago If I add a console.log
function declarePropTypesForIntersectionTypeAnnotation(propTypes, declaredPropTypes) {
+ console.log(propTypes)Node {
type: 'IntersectionTypeAnnotation',
start: 354,
end: 578,
loc:
SourceLocation {
start: Position { line: 14, column: 9 },
end: Position { line: 28, column: 8 } },
range: [ 354, 578 ],
types:

end: 445,
loc: [Object],

Error line: const typeNode = typeScope(annotation.id.name);

7 years ago i think console.log(context.getFilename())?

7 years ago @ljharb Found it. Seems to be because of the & flow operator:
props: {
cache?: ?string,
linkURL: string,
navigation: Object,
size?: ?number,
} & (
| {
username?: ?string,
}
| {
avatarURL: string,
}
| {
email?: ?string,
})Thanks, that's very helpful.

7 years ago Same problem, as @brunolemos found out, it seems to be related to Flow's &.
Throws with these test cases:
// @flow
import React from 'react';
import type { Node } from 'react'
type BasePropsType = {
className?: string,
text?: string,
}
type SomeComponentPropsType<T> = BasePropsType & {
something: string,
someOtherThing: T,
}
const SomeComponent = <T>(props: SomeComponentPropsType<T>): Node => <div />// @flow
import React from 'react';
import type { Node } from 'react'
type BasePropsType = {
className?: string,
text?: string,
}
type SomeComponentPropsType = BasePropsType & {
something: string,
}
const SomeComponent = (props: SomeComponentPropsType): Node => <div />// @flow
import React from 'react';
import type { Node } from 'react'
type BasePropsType = {
className?: string,
text?: string,
}
type SomeComponentPropsType<T> = BasePropsType & {
something: string,
someOtherThing: T,
}
const SomeComponent = (props: SomeComponentPropsType<*>): Node => <div />Does not throw with:
// @flow
import React from 'react';
import type { Node } from 'react'
type SomeComponentPropsType<T> = {
something: string,
someOtherThing: T,
}
const SomeComponent = <T>(props: SomeComponentPropsType<T>): Node => <div />node: v8.8.1

7 years ago Does anyone what version introduced this? I'm trying to figure out which version to rollback to.
mrchief
commented
7 years ago I tried rolling back to 7.3.0, 7.2.0 along with airbnb config ^15.0.0 but now I started getting this error:
error Definition for rule 'react/jsx-curly-brace-presence' was not found react/jsx-curly-brace-presence@mrchief if npm ls exits nonzero, nothing can be expected to work. You’ll have to roll back the airbnb config too if you want to roll back.

7 years ago I rolled back config to 15 from 16. 15 is what I have been using so far. Are you saying I need to roll back further?
mrchief
commented
7 years ago Ok, this combination works (my rollback solution):
"eslint": "^4.3.0",
"eslint-config-airbnb": "^15.1.0",
"eslint-loader": "^1.8.0",
"eslint-plugin-import": "^2.6.1",
"eslint-plugin-jsx-a11y": "^6.0.2",
"eslint-plugin-react": "^7.2.1",

6 years ago @mrchief Thanks! Those deps worked for me
Note: If you use "eslint-plugin-jsx-a11y": "5.x", you avoid this issue https://github.com/facebookincubator/create-react-app/issues/2631

6 years ago The crash was fixed in https://github.com/yannickcr/eslint-plugin-react/pull/1529. But the rule react/default-props-match-prop-types is still not working when Props are an intersection with a type imported from another file.
other-file.js:
// @flow
export type SomeType = {
baz: string,
};MyStatelessComponent.js:
// @flow
import React from 'react';
import type { SomeType } from './other-file';
type Props = SomeType & {
foo: string,
bar?: string,
};
const MyStatelessComponent = (props: Props) => (
<div>Hello {props.foo} {props.bar} {props.baz}</div>
);
MyStatelessComponent.defaultProps = {
bar: 'some default',
};Error:
#PATH#/MyStatelessComponent.js
15:3 error defaultProp "bar" has no corresponding propTypes declaration react/default-props-match-prop-types@ljharb Could this issue be reopened?

6 years ago @alexvb I believe this is a common issue with other rules as well (e.g. prop-types and no-unused-prop-types).
We should probably ignore validation when using types imported from another file?
ljharb
commented
6 years ago @alexvb can you file a new one for it instead?
