ok so a few people have joined and i really appreciate that. i honestly didnt think anyone would so i haven't worked on this for a few months (also am unemployed so ya know, searching for jobies.)
what would you use something like this for? the main reason i made this months and months ago was to be able to post software related stuff with code blocks lol. mainly inspired by people posting code in plain text on twitter, or just images of code you cant interact with.
again, thanks to everyone who has joined :)
@gregermendle
my gorsh, apparently when you use hono and openapi you can only use zod string for query parameters. https://github.com/honojs/middleware/issues/200
/*** {* query: QueryParamsSchema,* }*/const QueryParamsSchema = z.object({ page: z .string() .optional() .openapi({ param: { name: "page", in: "query", }, description: "The page you would like to view.", example: "1", })});
looks like you can also use a transform which gives the correct type:
const QueryParamsSchema = z.object({ page: ...transform((p) => parseInt(p))});
