ECONNREFUSED when dispatch action in nuxtServerInit

I am converting my Nuxt application to SSR – because I want to use nuxtServerInit and asyncData. These are the steps I have taken to convert it.

1. Remove ssr: false from nuxt.config.js
2. Dispatch actions to initialize store’s state in nuxtServerInit inside store/index.js

---

Now my nuxt.config.js looks like this

require("dotenv").config({ path: `.env.${process.env.NODE_ENV}` });

export default {
  router: {
    base: "/app/",
  },
  target: "static",
  head: {
    // Some head, meta, link config
  },
  css: ["@/assets/scss/main.scss"],
  styleResources: {
    scss: ["@/assets/scss/*.scss", "@/assets/scss/main.scss"],
  },
  plugins: ["@/plugins/apiFactory.js"],
  components: true,
  buildModules: [
    "@nuxtjs/eslint-module",
    ["@nuxtjs/dotenv", { filename: `.env.${process.env.NODE_ENV}` }],
  ],
  modules: [
    "bootstrap-vue/nuxt",
    "@nuxtjs/style-resources",
    ["nuxt-sass-resources-loader", "@/assets/scss/main.scss"],
  ],
  build: {
    splitChunks: {
      layouts: true,
    },
  },
};

And the store/index.js looks like this.

import axios from "axios";

export const state = () => ({
  data: [],
});

export const mutations = {
  setData(state, data) {
    state.data = data;
  },
};

export const actions = {
  async nuxtServerInit({ dispatch }) {
    // Before converting to SSR this action was dispatched in page/component that need this data
    await dispatch("fetchData");
  },
  async fetchData({ commit }) {
    const { data } = await axios.get("http://localhost:3030/my/api/path");
    commit("setData", data);
  },
};

export const getters = { /* some getters */ };

But after I restarted the development server – I was greeted with connect ECONNREFUSED 127.0.0.1:3030

These are the steps I’ve taken after that

• Check if the API on localhost:3030 is running and accessible – It’s running and accessible via direct URL and Postman
• Comment out the // await dispatch("fetchData"); in nuxtServerInit – restarted the dev server – site is accessible again but without initial data.

So, I suspected that the action dispatched in nuxtServerInit cause the problem – If it is how do I fix this problem or where should I look into next? Please let me know, Thanks!

Additional Information

• The API on localhost:3030 is Lumen version 7.2.2
• The application will be deployed on shared hosting

Answer

The main reason is that nuxt can’t connect to your host from where it resides. In my case it is docker container where 127.0.0.1 is… the container! So you have to change baseUrl to actually accessible server from that container.

const axiosPlugin: Plugin = ({ $axios, isDev }) => {
    if (isDev && process.server) $axios.setBaseURL('http://172.22.0.1:3000/api')
}
