Steps to reproduce

1. run vue create . with all default selection.

2. copy vue.config.js file into root directory

module.exports = {
  productionSourceMap: false,
  assetsDir: '../static',
  outputDir: '../static',
  indexPath: '../templates/index.html'
};

3. run vue run serve

What is expected?

Show the page normally just like in vue cli version 3

What is actually happening?

blank page with console error

chunk-vendors.js:1 
Uncaught SyntaxError: Unexpected token '<'

app.js:1 
Uncaught SyntaxError: Unexpected token '<'

---

Before i copy the vue.config.js, and i run the vue run serve, everything is normal.

assetsDir is defined realtive to outputDir, so now it's not a child folder of the latter.

Which means the webserver can't serve it.

It should be a child folder of the outputDir

@LinusBorg

assetsDir is defined realtive to outputDir, so now it's not a child folder of the latter.

It should be a child folder of the outputDir

In index.html file,
If i use the default value of assetsDir which is '' then it will looks like

<script src=/js/chunk-vendors.763c0f03.js>

What i am expecting is the output for assets is something like this

<script src=/../static/js/chunk-vendors.763c0f03.js>

How do i achieve it?

Ok solved!
Maybe i can share my solution and close this issue.

Actually I am using golang (with gin-gonic) for the backend and vue as frontend with structure

myapp
  - main.go
webapp
  - node_modules
  - public
  - src
  - package.json
  - other vue cli generated files..
dist
  - static
    - css
    - img
    - js
  - templates
    - index.html
  - favicon.ico

i use dist/ as output directory for npm run build and this directory also will used by golang as assets file.

main.go

package main

import (
	"net/http"
	"github.com/gin-gonic/gin"
)

func main() {
	router := gin.Default()
	router.GET("/", func(c *gin.Context) {
		c.HTML(http.StatusOK, "index.html", gin.H{"title": "MainMenu"})
	})

	router.StaticFile("./favicon.ico", "../dist/favicon.ico")
	router.Static("/static", "../dist/static")
	router.LoadHTMLGlob("../dist/templates/*")

	router.Run(":8081")
}

vue.config.js

module.exports = {
  productionSourceMap: false,  
  outputDir: '../dist',
  assetsDir: 'static',
  indexPath: 'templates/index.html'
};

@mirzaakhena 👍 Have similar issue. Solution in vue.config.js

fails with cli4

module.exports = {
  publicPath: 'a',
  outputDir: 'dist/a',
}

works with cli4

module.exports = {
  publicPath: '/a',
  outputDir: 'dist/a',
}

Thank you very much, this solution solved my deployement problem :)

[alfish24]

For my purposes this worked:

module.exports = {
  outputDir: '../static',
  indexPath: '../templates/index.html'
}

It seems assetsDir must be a child of outputDir, but not indexPath.

Thanks, it worked for me!
