This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.

API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.ts.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.

Preparation

  1. Run ngrok http 3000 and set the returned HTTPS URL to the endpoint URL of Sayaka-liff's LINE channel
  2. Run yarn dev and access localhost:3000

How to obtain the ID and access tokens needed for the back-end.

  1. access localhost:3000. Do not access the liff object on the source code yet.
  2. call the necessary liff methods such as liff.getIDToken() in the browser's developer console
  3. if called correctly, a value will be returned

Note that ID tokens expire after an hour or so.
