finish

The config allows to set the finish function that can be used to alter the logic of setting the token on the session or performing additional operations such as storing a new user in the database. The default sets the token on the ctx.session and also sets the user data such as name and id in the ctx.session.user property.

    finish = /* async */ (ctx, token, user, /* next */) => {
      ctx.session.token = token
      ctx.session.user = user
      ctx.redirect('/')
      // await storeInDb(token, user)
      // await next()
    },
