Using camel case with kanel-kysely

[sebastian-schuler]

I want to use Kyselys CamelCasePlugin, how can I generate the types with Kanel accordingly? Is there some sort of workaround in place?

I don't have any experience with that plugin but you can solve almost anything by writing a pre-render hook.

For future readers:

import { camelCase } from 'change-case';
import kanel, { type Output } from 'kanel';
import kanelKysely from 'kanel-kysely';

const camelCaseHook = (output: Output): Output =>
  Object.fromEntries(
    Object.entries(output).map(([path, fileContents]) => [
      path,
      {
        ...fileContents,
        declarations: fileContents.declarations.map((declaration) =>
          declaration.declarationType === 'interface' ?
            {
              ...declaration,
              properties: declaration.properties.map((property) => ({
                ...property,
                name: camelCase(property.name),
              })),
            }
          : declaration,
        ),
      },
    ]),
  );

await kanel.processDatabase({
  // ...
  preRenderHooks: [kanelKysely.makeKyselyHook(), camelCaseHook],
});

Maybe this hook could come bundled with kanel-kysely?

I'd be happy to if this is something that is common. The thing is that I don't really use Kysely myself, so I just provided what appeared to be what is expected. PR's from people with proper knowledge are very welcomed! :-)
