I deployed a Django+VueJS app that uses django webpack loader in order to render Vue apps in my Django templates. I used Nginx and Gunicorn to deploy the app to a DigitalOcean VPS, everything works without any problem but i have some doubts on how to edit my components in production, since i'm fairly new to Vue
Here is my vue.config:
const BundleTracker = require("webpack-bundle-tracker");
const BundleAnalyzerPlugin = require("webpack-bundle-analyzer").BundleAnalyzerPlugin;
const pages = {
'main': {
entry: './src/main.js',
chunks: ['chunk-vendors']
},
}
module.exports = {
pages: pages,
runtimeCompiler: true,
filenameHashing: false,
productionSourceMap: false,
publicPath: process.env.NODE_ENV === 'production'
? 'static/vue'
: 'http://localhost:8080/',
outputDir: '../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": ["*"]})
}
};
So in order to deploy the Vue part i did npm run build and npm created a bunch of files in my static directory. Now, every time i edit a component, in order to see the changes on the web, i do npm run build every time, which takes some time. Is this how am i supposed to do it? Or is there a shorter way?
I don't know about django, But I know about vue..
is this how am I supposed to do it?
For me, I don't suggest it, you can use your django as a backend for your frontend
that should mean you would have 2 servers running. 1 for your django and 1 for your vue app. use XHR request to access your django App, remember to handle CORS. IMHO I don't want vue to be used as a component based framework.
is there a shorter way.
YES, and this is how you do it.
add to package.json
{
...,
scripts: {
...,
'watch' : 'vue-cli-service build --watch --inline-vue',
...,
}
}
while using the following settings in vue.config.js
module.exports = {
'publicPath': '/django/path/to/public/folder',
'outputDir': '../dist',
'filenameHashing': false,
runtimeCompiler: true,
'css': {
extract: true,
},
}
i forgot about how publicPath and outputDir works..
but you can check it out here https://cli.vuejs.org/config/#publicpath
regarding the code on the package.json file..
you can check it here

I use 2 entry files, startpage.js and subpage.js, and assign them successfully to their HTML files via the HTMLWebpackPlugins chunks parameter.
But since that solution requires to include the CSS files in both the startpage.js and subpage.js, which makes for "double the trouble" (at least during the build process), I decided to create another file, app_head, and put the import 'main.css' statement there. (And I also have a vendor file that should be placed in the header of the HTML, which should happen by adding _head according to the documentation: https://github.com/architgarg/html-webpack-injector - but that does not work either...)
This is the current webpack config (excerpt):
module.exports = {
entry: {
app_head: './src/css/main.css',
vendor_head: './src/scripts/vendor/_all_vendor.js',
startpage: './src/scripts/startpage.js',
subpage: './src/scripts/subpage.js',
},
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, '../public'),
publicPath: '/'
},
plugins: [
new HtmlWebpackPlugin({
filename: 'index.html',
template: './src/templates/index.ejs',
chunks: ['app_head', 'vendor_head', 'startpage'],
chunksConfig: {
defer: ['startpage']
},
excludeChunks: ['subpage'],
bodyCss: 'is-startpage',
}),
new HtmlWebpackPlugin({
filename: 'publication.html',
template: './src/templates/publication.ejs',
chunks: ['subpage'],
chunksConfig: {
defer: ['subpage']
},
excludeChunks: ['startpage'],
bodyCss: 'is-subpage',
}),
[...]
The app_head.css is placed properly in the head section of the HTML, but it also generates a useless app_head.js, which only contains webpack code. Unfortunately, I do not know of any way how to exclude that file without also excluding the CSS.
Is there a better way to separate the CSS generation process without producing overhead or garbage?
The problem is you did not initialized the html-webpack-injector plugin.
// import above
const HtmlWebpackInjector = require('html-webpack-injector');
plugins: [
new HtmlWebpackPlugin(...),
new HtmlWebpackPlugin(...),
new HtmlWebpackInjector() // add this in plugins array
When I build (netflify build) my Gridsome personal website, tailwind CSS classes doesn't work and the website look's like without CSS.
I have already tried to build without git, reinstall tailwind...
I show my gridsome config if that's the problem:
const tailwind = require('tailwindcss');
const purgecss = require('#fullhuman/postcss-purgecss');
const postcssPlugins = [
tailwind(),
]
if (process.env.NODE_ENV === 'production') postcssPlugins.push(purgecss());
module.exports = {
siteName: 'Zolder | Works',
plugins: [],
css: {
loaderOptions: {
postcss: {
plugins: postcssPlugins,
},
},
},
}
I had this issue as well. I used the Tailwind Plugin for Gridsome and it worked locally but when deploying to Netlify, the Tailwind css wasn't getting added.
Referencing this starter file: https://github.com/drehimself/gridsome-portfolio-starter/blob/master/src/layouts/Default.vue
I added the main.css with all the Tailwind imports file to the end of the Default Layout template instead, and this worked for me.
You can add Tailwind to your Gridsome project with these steps:
edit gridsome.config.js
module.exports = {
siteName: "Zolder",
plugins: [],
chainWebpack: config => {
config.module
.rule("postcss-loader")
.test(/.css$/)
.use(["tailwindcss", "autoprefixer"])
.loader("postcss-loader");
}
};
create a global.css file in ./src/styles
#tailwind base;
#tailwind components;
#tailwind utilities;
import global.css in main.js
import './styles/global.css'
Trying to use reactjs + django webpack loader + webpack 4.
Everything builds perfectly main and other chunks files are generated successfully.
Unfortunately, page getting blank and its seems like corresponding chunk file is not calling/loading. only laoding main chunk. Is there anything missing in my webpack config?

I think the .json is built in webpack4 by default so there may be something wrong with my webpack config?
Version used:
webpack: v4.4.1
typescript: 2.7.2
declare module in d.ts file
declare module "*.json"
Add a field in tsconfig.json in compiler options
"typeRoots": [ "node_modules/#types", "./typings.d.ts" ],
Now import into file (.tsx)
import * as data from "./dat/data.json";
Webpack#4.4.1 and Typescript#2.7.2
Hope this helps!!!

Ref2: https://github.com/Microsoft/TypeScript-React-Starter/issues/12
Although answers are helpful to load the JSON file as a module, they are limited in many aspects
First: the typescript can load by default JSON files, you only need to add into tsconfig.json below line:
{
...
"resolveJsonModule": true,
...
}
second: the suggested solution will enable implicitly for type check and auto-completion
P.S. the attached image is from a tutorial that talks about the same subject click here to check more
Personnaly, uncommenting :
"allowSyntheticDefaultImports": true /* Allow default imports from modules with no default export. This does not affect code emit, just typechecking. */,
in the file tsconfig.json did the trick.
I found the hint here.
