path case insensitive?

[ioucyf]

Hello all,

what's the proper way to make the routes case insensitive?

for example:

api/user and api/USER would point to the same endpoint?

while keeping params etc case sensitive?

Can be done! Except for the "/api" part, everything else is case insenstive (deploying at cloudflare workers):

index.ts

app.all("/api/*", (c) => {
	const router = customRouterc.env);
	// lowercase it
	const url = new URL(c.req.url);
	url.pathname = url.pathname.toLowerCase() || "/";
	const newReq = new Request(url.toString(), c.req.raw);
	return router.fetch(newReq, c.env, c.executionCtx);
});

build your custom router that takes the lowercased pathname

/// router.ts
export function customRouter(env: CloudflareBindings): Hono {
	const router = new Hono();
        router.post("/api/login", async (c) => {  ... })    // will accept any combination of login, Login, LoGiN...
        router.get("/api/youraction", async (c) => {  ... });
        // ....
        return router;
}

Use a pre-routing middleware, not a catch-all handler, so Hono's matcher + params still work. Rewrite only url.pathname (not the whole URL string, query params and signed tokens can be case-sensitive) and swap c.req.raw with a new Request on the lowercased URL before next(). In production prefer a 301 redirect over an in-place rewrite so you have one canonical URL and CDNs cache correctly. If you need the original casing of a specific segment, stash it on c.set('rawPath', ...) before rewriting.
