Deploy Vue to GitHub Pages. Error with vue-router

Update 2020

baseUrl is Deprecated since Vue CLI 3.3, please use publicPath instead.

If you are using Vue CLI >= 3.3 you might want to check out this vue-cli plugin which automates github pages deployment using github actions.

By default, Vue CLI assumes your app will be deployed at the root of a domain, e.g. https://www.my-app.com/. If your app is deployed at a sub-path, you will need to specify that sub-path using this option. For example, if your app is deployed at https://www.foobar.com/my-app/, set baseUrl to '/my-app/'. So :

1. Create a new file in root directory of your project and name it ‘vue.config.js’

2. In ‘vue.config.js’ file paste the following code:

   module.exports = { baseUrl: ‘/my-first-project/’ }

NOTE: in baseUrl inside the // chars you have to put the name of your project.

1. For Vue3, Please make the configuration as below:

import { createRouter, createWebHistory } from 'vue-router';

const router = createRouter({
  history: createWebHistory('/your-github-repo/'),
  routes: [
   // put your routes
  ]
});

2. For Vue2, Please make the configuration as below:

import VueRouter from 'vue-router';

const router = new VueRouter({
  mode: 'history',
  base: '/your-github-repo/',
  routes: [
    // put your routes
  ]
});

If still problem persists, please create vue.config.js file in root location of your vue app and add the following code:

module.exports = {
  publicPath: process.env.NODE_ENV === 'production'
  ? '/your-github-repo/' // note the trailing slash
  : '/',
}

• Vue base option moved - resource
• Public path - resource

can you try this in your main.js

new Vue({
    el: '#app',
    router,
    components: { App },
    template: '<App/>',
});

As they said baseUrl is deprecated, use publicPath

module.exports = { publicPath: '/your-repo/' }
