Docgen: Errors on components whose names are keywords

[preciselywilliam]

The storybook project builds fine:

When I load the page I get a cryptic Javascript error:

My deps are as below (let me know if there are other relevant deps):

    "@storybook/addon-a11y": "^6.0.5",
    "@storybook/addon-actions": "^6.0.5",
    "@storybook/addon-knobs": "^6.0.5",
    "@storybook/addon-links": "^6.0.5",
    "@storybook/addons": "^6.0.5",
    "@storybook/react": "^6.0.5",
    "@storybook/source-loader": "^6.0.5",
    "react": "16.13.1",

Not really sure where to start debugging, any ideas on what could be wrong?

do you have a repro i can look at? i recently updated that part of the code and it's possible that you're hitting some kind of corner case bug

I went through and disabled story by story until I found the one causing the crash. It was below, where Toaster is a function which has to be called as Toaster.create();

export default {
	title: 'Toaster',
	component: Toaster,
};

My mistake, thanks for having a look at the issue. I'll leave the issue open if you want to take further action. @shilman

I had a similar problem in a project after upgrading Storybook, turned out I head a react component called delete in a file called delete.tsx and at some point Storybook tried to generate some code that looked something like delete.module = ... which caused the SyntaxError. Renaming the component and the file solved it (never checked which one was the problem).

@TheKnarf nailed this one. A file named delete.tsx causes this failure mode.

Same issue here.
In my case instead of having a file delete.tsx I had a switch.tsx which caused the same problem:
(SyntaxError: Unexpected token '.')

[boakenfull]

Yep, exactly the same issue here - I have switch.tsx which causes the same problem. Changing the file name to somethingElse.tsx everything compiles fine

[loelsonk]

Same issue, (SyntaxError: Unexpected token '.') and switch.tsx :D

[kilinkis]

switch.tsx too!

Still a bug

Same issue. For me it was a folder called switch with an index.tsx. Renaming the folder solved the issue.

same here

[PetterRuud]

Manually set the display name solved this for me

switch.tsx
...
Switch.displayName = 'Switch';
...

[jorgenbuilder]

Manually set the display name solved this for me

switch.tsx ... Switch.displayName = 'Switch'; ...

Confirming this solution worked in my case. Nice fix @PetterRuud!

[ndelangen]

I think this got fixed in 7.0 beta.

[reify-benjamin-solum]

As of 7.6.4 I'm still seeing this issue in Storybook. Above fixes work.

[andreyna1808]

Yeps, versions 7.6.12

If you had a problem with the switch component in the storybook, try changing it to "toogle", or similar names. The problem itself is the name guys
