jsx parse error

[Andro Babu]

Hi @fwouts,

When using our components, I'm facing issue in parsing jsx file.

% yarn test:visual:new shoot
yarn run v1.22.5
$ viteshot shoot

Earlier I used to declare in jest.screenshot.config.js file

transformIgnorePatterns: [`node_modules/(?!(gatsby|mylib)/)`]

Hey @rambabusaravanan, great bug report.

Viteshot currently can't support any JSX in js files, but I just managed to get that to work in reactpreview.com, which works in a very similar way, so I should be able to fix it.

Give me a day or two 🙂

[François Wouts]

Hey @rambabusaravanan, v0.1.4 is out with support for JSX in .js files.

However, this cannot apply to JSX inside node_modules/, which appears to be the case with Gatsby. In case you're curious, the problematic code inside Vite is https://github.com/vitejs/vite/blob/887c247984abc0f80d8b19a1d681855944f6d01a/packages/vite/src/node/optimizer/index.ts#L245

It looks like you won't be able to take screenshots of components that depend on Gatsby 😞 Other, more isolated components should however be fine.

[François Wouts]

Hey @rambabusaravanan, it took a while to get that PR merged into Vite, but it's now done :)

You should be able to use Viteshot with Gatsby, at least from v0.1.8. Let me know how you go!

[Andro Babu]

Sure will give it a try. Thanks for the update.
