How to use const session = c.get("session") and const user = c.get("user") in Hono when routes?

Hi everyone, I'm using Hono but the only way I can retrieve c.get("user") is if I export my app variables type? Is there a more elegant way to do this? Maybe export the "whole app" in each route instead of just variables? index.ts:

// Define app variables type to be used across routes
export type AppVariables = {
  user: typeof auth.$Infer.Session.user | null;
  session: typeof auth.$Infer.Session.session | null;
};

// Initialize Hono app
const app = new Hono<{
  Variables: AppVariables;
}>();

// Auth routes with Better-Auth
app.on(["POST", "GET"], "/api/auth/*", (c) => {
  return auth.handler(c.req.raw);
});

// Middlewares
app.use("/api/auth/*", corsMiddleware);
app.use("*", sessionMiddleware, logger(), prettyJSON());

// eslint-disable-next-line @typescript-eslint/no-unused-vars
const routes = app.basePath("/api").route("/threads", threads);
export type AppType = typeof routes;

// Serve static files
app.get("*", serveStatic({ root: "./frontend/dist" }));
app.get("*", serveStatic({ path: "./frontend/dist/index.html" }));

// Export the app with server configuration
export default {
  port: process.env["PORT"] || 3000,
  hostname: "0.0.0.0",
  fetch: app.fetch,
};

// Define app variables type to be used across routes
export type AppVariables = {
  user: typeof auth.$Infer.Session.user | null;
  session: typeof auth.$Infer.Session.session | null;
};

// Initialize Hono app
const app = new Hono<{
  Variables: AppVariables;
}>();

// Auth routes with Better-Auth
app.on(["POST", "GET"], "/api/auth/*", (c) => {
  return auth.handler(c.req.raw);
});

// Middlewares
app.use("/api/auth/*", corsMiddleware);
app.use("*", sessionMiddleware, logger(), prettyJSON());

// eslint-disable-next-line @typescript-eslint/no-unused-vars
const routes = app.basePath("/api").route("/threads", threads);
export type AppType = typeof routes;

// Serve static files
app.get("*", serveStatic({ root: "./frontend/dist" }));
app.get("*", serveStatic({ path: "./frontend/dist/index.html" }));

// Export the app with server configuration
export default {
  port: process.env["PORT"] || 3000,
  hostname: "0.0.0.0",
  fetch: app.fetch,
};

example of a route (thread.ts):

const app = new Hono<{ Variables: AppVariables }>()
  .use("/*", rateLimitMiddleware)
  .post("/", zValidator("json", searchRequestSchema), async (c) => {
    const user = c.get("user");

    if (!user) {
      return c.json({ error: "Unauthorized" }, 401);
    }

  ...

const app = new Hono<{ Variables: AppVariables }>()
  .use("/*", rateLimitMiddleware)
  .post("/", zValidator("json", searchRequestSchema), async (c) => {
    const user = c.get("user");

    if (!user) {
      return c.json({ error: "Unauthorized" }, 401);
    }

  ...

you can try c.var.user or are you asking about something different?

I’m wondering if there is a better way than having to import variables in each individual route?

Blank•5mo ago

create a utility function

export const createRouter = () => new Hono<{...}>();

export const createRouter = () => new Hono<{...}>();

and call this

MarvinKROP•5mo ago

Yeah that’s what I thought, thx!

Blank•5mo ago

its more of to do with how hono works than better-auth

MarvinKROP•5mo ago

True sorry wrong discord I guess haha

MarvinKROP•5mo ago

doing this actually breaks my Hono RPC setup?

MarvinKROP•5mo ago

Think i'll stick to variables for the moment, thx

Blank•5mo ago
