Is this a solution for nuxt3 cross domain proxy please?

//nuxt.config.ts
modules: [
    '@vueuse/nuxt',
    '@pinia/nuxt',
    '@nuxtjs/color-mode',
    'nuxt-proxy',
  ],

proxy: {
    options: {
      target: 'https://localhost:8100',
      changeOrigin: true,
      pathRewrite: {
        '^/api/': '/',
      },
      pathFilter: [
        '/api/',
      ],
    },
  },

//~/api/auth.ts
getInfo() {
      return useFetch('/api/auth/auth-member/info', {
        method: 'GET',
        headers: {
          Authorization: useCookie('token').value,
        },

      })
    },

@balck-paint, it works perfectly with cross-domain proxy. The problem is that you have a self-signed certificate on your https://localhost:8100, and the package that is used to create this middleware blocking it by default.

Simply add secure: false to your configuration:

proxy: {
    options: {
      target: 'https://localhost:8100',
      secure: false,
      changeOrigin: true,
      pathRewrite: {
        '^/api/': '/',
      },
      pathFilter: [
        '/api/',
      ],
    },
  },

Checked on nuxt.js 3.0.0-rc.12
