pietrofxq opened this issue · comments
What version of TypeScript are you using?
3.1.1
What version of typescript-eslint-parser
are you using?
21.0.2
Eslint version: 5.12.0
What code were you trying to parse?
declare module "@ajs/context-path" {
export default function (): string;
}
and
const BaseState = ({ title, hint, src, ...props }) => (
<MessageBox {...props}>
<MessageImage src={src} />
<MessageText>
<MainMessage>{title}</MainMessage>
<p>{hint}</p>
</MessageText>
</MessageBox>
)
What did you expect to happen?
No eslint errors
.eslintrc:
{
"extends": [
"eslint:recommended",
"plugin:react/recommended",
"@atlassian/atlassian-fecq",
"prettier"
],
"settings": {
"react": {
"pragma": "React",
"version": "^16.5.2"
}
},
"parser": "typescript-eslint-parser",
"env": {
"es6": true,
"browser": true,
"node": true
},
"globals": {
"I18n": true
},
"plugins": [
"react",
"typescript"
],
"parserOptions": {
"sourceType": "module",
"ecmaFeatures": {
"experimentalObjectRestSpread": true,
"jsx": true
}
}
}
Am I missing something? Using typescript-eslint-parser disables jsx parsing even though I have jsx:true
in parserOptions
and throws this cannot read property 'name' of null
error.
"parserOptions": {
"sourceType": "module",
"jsx": true
}
@armano2 thanks... that got rid of the react issues. Now I still have "cannot read property 'name' of null"
This seems to be an issue with vscode-eslint
. Running eslint
in the command line doesn't give me such error, it only shows up in the vscode 'problems' panel
can you try setting up in vscode
eslint.options: options to configure how ESLint is started using the ESLint CLI Engine API. Defaults to an empty option bag. An example to point to a custom .eslintrc.json file is:
{
"eslint.options": { "configFile": "path/.eslintrc.json" }
}
looks like its not using typescript-eslint-parser
same issue :/ I can see that vscode is reading the file because when I change typescript-eslint-parser
to babel-eslint
the error changes instantly. Looks like everything is working properly despite of the error showing up in the "problems" tab, I'll live with it for now
i was able to reproduce it in console :)
and looks like issue is in typescript-estree
ok issue is here https://github.com/eslint/typescript-eslint-parser/blob/master/analyze-scope.js#L323
there is no support for anonymous functions :)
Should hopefully be fixed by #596
