Fix i18n routing

[calmery]

I changed my code according to the "I18N routing" in the official documentation, but it did not work correctly.

$ deno --version
deno 1.14.0 (release, x86_64-apple-darwin)
v8 9.4.146.15
typescript 4.4.2

$ aleph --version
aleph.js 0.3.0-beta.14
deno 1.14.0
v8 9.4.146.15
typescript 4.4.2

Maybe this bug is caused by a change made in 16483f9. In this commit, this code also needed to be changed.

Check the problem by using v0.3.0-beta.14 and making the following changes.

// ./examples/hello-world/aleph.config.ts
import type { Config } from "aleph/types.d.ts";

export default <Config> {
  i18n: {
    defaultLocale: "ja",
    locales: ["en", "ja"],
  },
};

// ./examples/hello-world/app.tsx
import { useRouter } from "aleph/react";

...

const { defaultLocale, locales } = useRouter();

// Before: defaultLocale=ja locales=[]
// After: defaultLocale=ja locales=["en","ja"]
console.log(
  `defaultLocale=${defaultLocale}`,
  `locales=${JSON.stringify(locales)}`,
);

...

return (

  ...

  <a href="/en">en</a> {/* 404 */}
  <a href="/">ja</a>

  ...

);

Regardless of the ssr option, the final rendering result will be as follows.

Before (e47d1ed)	After (https://github.com/calmery/aleph.js/commit/3e25d5d98ea30155e34d95b0f788d91d66059e46)

After the fix, I have confirmed that i18n routing works correctly with the following command.

$ ALEPH_DEV=true deno run -A --unstable --location=http://localhost cli.ts dev ./examples/hello-world -L debug
