Deploy VueJS App in a subdirectory
For Vue CLI 3 it is pretty simple.
Edit your vue.config.js (if there is none, create it in project root directory) and add following lines:
module.exports = { baseUrl: "./"};Or whatever sub-directory you want.
You may also decide according to NODE_ENV. See the docs.
module.exports = { baseUrl: process.env.NODE_ENV === 'production' ? '/production-sub-path/' : '/'}UPDATE
As mentioned in comments below, for Vue CLI 3.3+ use publicPath property instead of baseUrl.
Assuming you are using the webpack template from vue-cli, you need to edit the assetsPublicPath property in config/index.js - notice there is one for build and for dev
Check out Handling Static Assets section in the docs for more info.
Update:
Newer link for CLI v3+ users: https://cli.vuejs.org/guide/html-and-static-assets.html
Notice the property is just called publicPath
