ERR_ABORTED 404 (Not Found) error in VueJS

Question

I deployed a Django+VueJS application to a Digital Ocean droplet using Nginx, the Django app is working but i can't see the VueJS components loaded by Webpack (i'm using Django-Webpack-Loader).

In my console, i keep seing these errors:

GET http://MYURL/static/vue/js/stopwatch.js net::ERR_ABORTED 404 (Not Found)
GET http://MYURL/static/vue/js/index.js net::ERR_ABORTED 404 (Not Found)

Which means that the static folder was not found. I made sure to use npm run build and manage.py collectstatic and i can see that the static folder is there, even though the app doesn't see it. Here is the path:

django-vue-mpa
   |-vue_frontend
   |-django_vue_mpa
     |-static

The full code of the application is here (i just cloned that repository and tried to deploy it).

Here is my vue.config.js (i think the problem might be here):

const BundleTracker = require("webpack-bundle-tracker");
const BundleAnalyzerPlugin = require("webpack-bundle-analyzer").BundleAnalyzerPlugin;


const pages = {
    "stopwatch": {
        entry: "./src/stopwatch.js",
        chunks: ["chunk-moment", "chunk-vendors"],
    },
    "index": {
        entry: "./src/index.js",
        chunks: ["chunk-vendors"],
    },
    'vue_app_01': {
        entry: './src/main.js',
        chunks: ['chunk-vendors']
    },
    'vue_app_02': {
        entry: './src/newhampshir.js',
        chunks: ['chunk-vendors']
    },
}

module.exports = {
    pages: pages,
    filenameHashing: false,
    productionSourceMap: false,
    publicPath: process.env.NODE_ENV === 'production'
        ? '/static/vue'
        : 'http://localhost:8080/',
    outputDir: '/django-vue-mpa/django_vue_mpa/static/vue/',

    chainWebpack: config => {

        config.optimization
            .splitChunks({
                cacheGroups: {
                    moment: {
                        test: /[\\/]node_modules[\\/]moment/,
                        name: "chunk-moment",
                        chunks: "all",
                        priority: 5
                    },
                    vendor: {
                        test: /[\\/]node_modules[\\/]/,
                        name: "chunk-vendors",
                        chunks: "all",
                        priority: 1
                    },
                },
            });

        Object.keys(pages).forEach(page => {
            config.plugins.delete(`html-${page}`);
            config.plugins.delete(`preload-${page}`);
            config.plugins.delete(`prefetch-${page}`);
        })

        config
            .plugin('BundleTracker')
            .use(BundleTracker, [{filename: '../vue_frontend/webpack-stats.json'}]);

        // Uncomment below to analyze bundle sizes
        // config.plugin("BundleAnalyzerPlugin").use(BundleAnalyzerPlugin);
        
        config.resolve.alias
            .set('__STATIC__', 'static')

        config.devServer
            .public('http://localhost:8080')
            .host('localhost')
            .port(8080)
            .hotOnly(true)
            .watchOptions({poll: 1000})
            .https(false)
            .headers({"Access-Control-Allow-Origin": ["*"]})

    }
};

Here is my nginx config:

server {
    listen 80;
    server_name http://MYURL/;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /django-vue-mpa/django_vue_mpa/static;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/django-vue-mpa/django-vue-mpa.sock;
    }
}

And here is my settings.py:

Answer 1

Check the difference between root and alias nginx directives. For your case you should use

location /static/ {
    root /django-vue-mpa/django_vue_mpa;
}

instead of

location /static/ {
    root /django-vue-mpa/django_vue_mpa/static;
}

You'd see nginx searches files on a wrong path if you looked at its error log.
