# Hono

> Using `inertia-server` with Hono

Use the Hono adapter to inject an `inertia` helper into request context.

## Import

```ts theme={null}
import { honoAdapter } from "inertia-server/hono";
```

## Basic setup

Remember to configure your helpers according to the installation guide [installation](/getting-started/installation)

```ts theme={null}
import { Hono } from "hono";
import { honoAdapter } from "inertia-server/hono";
import { createHelper } from "./inertia";

const app = new Hono();

app.use("*", honoAdapter(createHelper));

app.get("/", (c) => {
  return c.get("inertia").render(homePage({ title: "Dashboard" }));
});
```

## Setup with flash/session support

If you use `inertia.flash(...)` or `inertia.errors(...)`, provide a flash adapter.
Your session implementation may vary, in the example we are using a pseudo-code
for a simple cookie based sessions.

```ts theme={null}
import { Hono } from "hono";
import { honoAdapter } from "inertia-server/hono";
import { createHelper } from "./inertia";
import { sessionStore } from "./session";

const app = new Hono();

app.use("*", async (c, next) => {
  const sessionId = sessionStore.getSessionId(c.req.raw);
  c.set("sessionId", sessionId);
  await next();
  c.header("Set-Cookie", sessionStore.createCookieHeader(sessionId));
});

app.use(
  "*",
  honoAdapter(createHelper, (c) => ({
    getAll: () => sessionStore.getFlash(c.get("sessionId")),
    set: (data) => sessionStore.setFlash(c.get("sessionId"), data),
  })),
);
```

## Route usage

After middleware is attached, handlers can use `c.get("inertia")`.

```ts theme={null}
app.post("/login", (c) => {
  const inertia = c.get("inertia");
  inertia.flash("success", "Logged in");
  return inertia.redirect("/dashboard");
});
```
