Extending Application Context

[joshamaju]

How can I extend the Hono application context to achieve the example below:

import { Hono } from "hono";

const app = new Hono();

// in-built context method
app.get("/", c => c.json({}))

// custom context method
app.get("/about", c => c.customMethod({}))

---

get/set works, but it's a lot more messy:

...

app.use((c, next) => {
    c.set("customMethod", fn);
    return next();
})

// custom context method
app.get("/about", c => {
    const customMethod = c.get("customMethod");
    return customMethod();
})

Usecase

Ability to extend the application context will make it possible for third-party libraries to provide express like experience. For example:

import express from "express";
import customLibrary from "custom-library";

const app = express();

app.use(customLibrary())

// OR

customLibrary(app);

app.get("/about", (req, res) => res.customMethod(...))
