environment variables not visible in production - vue.js

I've built a Vue CLI project with an .env.development.local and .env.production.local file.
When I run npm run serve it loads the variables fine. When I run npm run build and serve the dist directory, it doesn't load the variables.
I've made sure the variables are prefixed with 'VUE_APP_' and when I console.log process.env I get just {NODE_ENV: "production", BASE_URL: "/"}
How can I get the environment variables to be read in production?
Edit: I've included one of my .env files as an example:
NODE_ENV=production
VUE_APP_API_URL=http://10.0.0.28:4323/api
VUE_APP_HOME_URL=http://localhost:9098

VueJS change links of script files in index.html

I created a simple app with VueJS and run it on a plattform.
Unfortunately the JS files can not be found.
The index.html searches here:
http://homepage.de:8080/static/js/app.b22ce679862c47a75225.js
But the files are here:
http://homepage.de:8080/app_direct/vue/static/js/app.b22ce679862c47a75225.js
Is there a way to change some parameters in a file to link to the correct source?
I used this old way to create my vue app if it matters (I do not have a vue-config.js).
$ npm install -g vue-cli
$ vue init webpack my-project
I then dockerize it with this Dockerfile:
FROM node:lts-alpine
# install simple http server for serving static content
RUN npm install -g http-server
# make the 'app' folder the current working directory
WORKDIR /app
# copy both 'package.json' and 'package-lock.json' (if available)
COPY package*.json ./
# install project dependencies
RUN npm install
# copy project files and folders to the current working directory (i.e. 'app' folder)
COPY . .
# build app for production with minification
RUN npm run build
EXPOSE 8080
CMD [ "http-server", "dist" ]

How do I specify a valid entry point / file for Vue projects?

Came back to an old Vue project. Try to bring it up on my local machine using 'vue serve' and I got the following error.
How do I specify a valid entry point for vue projects?
Command:
vue serve
Terminal Error:
"Failed to locate entry file in /Users/$username/Desktop/my-project.
"Valid entry file should be one of: main.js, index.js, App.vue or app.vue.
vue serve src/main.js
Need to add the file to start from after the serve command
npm run serve
need to type this command .
A better way of doing this would be to specify the path to the main.js file in the package.json file as follows:
"scripts": {
"dev": "vue serve src/main.js",
"prod": "vue build src/main.js"
}
And then simply run
npm run dev
for serving the project in the development environment and
npm run prod
for creating a production build under dist folder

How do I optimize build of custom mode in vue cli 3

We can set custom modes in cli 3.
Because it is not a production mode, it would not be a optimized build.
How do I set config to custom mode to reach the optimized build as production mode.
custom mode(staging) in package.json
The files of default production mode(optimized), command: npm run build
The files of custom mode(staging) (not optimized), command: npm run staging
Thanks in advance.
I think you are Mixing between two things first vue build app.vue command builds a production ready bundle.
Modes are just another name for environment, which specifies if you’re in development, production or test mode.
if you want to associate different mode with your build you can append it like that vue-cli-service build --mode development. by --mode you assign what environment variables you need with that build.
if you want the stage build to be optimized as production just put NODE_ENV=production in the start of your .env.staging file .
ref: CLI docs modes and env in cli docs

npm run build --mode [.env.mode] not working as expected

What I've done so far:
I've been trying to setup multiple build modes like staging, testing, production and development based on NODE_ENV=production. So I'm keeping the respective files in the root of the project folder like:
.env.production
.env.staging
.env.testing
.env.development
Now, all these files are having
NODE_ENV=production
VUE_APP_ENV=<mode>
The document that I followed clearly states that,
vue-cli-service build --mode staging builds a production app in
staging mode, using .env, .env.staging and .env.staging.local if they
are present.
Problem:
As expected, running the command npm run build --mode staging is to give a production build with variable as listed in the .env.staging file. However, production variables are loaded instead of staging.
Ref:
https://cli.vuejs.org/guide/mode-and-env.html#example-staging-mode
https://forum.vuejs.org/t/how-to-build-production-app-with-varying-config/29708
You need to use the following command
npm run build -- --mode staging
All arguments before -- are considered npm arguments and arguments after -- are passed to vue-cli-service
I was having the same problem, I figured out my problem was from using a beta version (3.0.0-beta.9) of #vue/cli-service so changing it to the rc version (3.0.0-rc.3) worked. So in my package.json under devDependencies I changed it to "#vue/cli-service": "^3.0.0-rc.3"

Which command do I use to generate the build of a Vue app?

What should I do after developing a Vue app with vue-cli?
In Angular there was some command that bundle all the scripts into one single script.
Is there something the same in Vue?
I think you've created your project like this:
vue init webpack myproject
Well, now you can run
npm run build
Copy index.html and /dist/ folder into your website root directory. Done.
If you've created your project using:
vue init webpack myproject
You'd need to set your NODE_ENV to production and run, because the project has web pack configured for both development and production:
NODE_ENV=production npm run build
Copy dist/ directory into your website root directory.
If you're deploying with Docker, you'd need an express server, serving the dist/ directory.
Dockerfile
FROM node:carbon
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
ADD . /usr/src/app
RUN npm install
ENV NODE_ENV=production
RUN npm run build
# Remove unused directories
RUN rm -rf ./src
RUN rm -rf ./build
# Port to expose
EXPOSE 8080
CMD [ "npm", "start" ]
in your terminal
npm run build
and you host the dist folder. for more see this video
To deploy your application to prod environment add
"build": "vue-cli-service build --mode prod"
in your scripts in package.json file.
Open your main.js and add
Vue.config.productionTip = false;
right after your imports.
Then open your cli in the project folder and run this command
npm run build
This will make a dist folder in your project directory you may upload that dist folder in your host and your website will be live
If you run into problems with your path, maybe you need to change the assetPublicPath in your config/index.js file to your sub-directory:
http://vuejs-templates.github.io/webpack/backend.html
The vue documentation provides a lot of information on this on how you can deploy to different host providers.
npm run build
You can find this from the package json file. scripts section. It provides scripts for testing and development and building for production.
You can use services such as netlify which will bundle your project by linking up your github repo of the project from their site. It also provides information on how to deploy on other sites such as heroku.
You can find more details on this here
The commands for what specific codes to run are listed inside your package.json file under scripts. Here is an example of mine:
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
If you are looking to run your site locally, you can test it with
npm serve
If you are looking to prep your site for production, you would use
npm build
This command will generate a dist folder that has a compressed version of your site.
THIS IS FOR DEPLOYING TO A CUSTOM FOLDER (if you wanted your app not in root, e.g.
URL/myApp/) - I looked for a longtime to find this answer...hope it helps someone.
Get the VUE CLI at https://cli.vuejs.org/guide/ and use the UI build to make it easy. Then in configuration you can change the public path to /whatever/ and link to it URL/whatever.
Check out this video which explains how to create a vue app using CLI if u need more help: https://www.youtube.com/watch?v=Wy9q22isx3U
For NPM => npm run Build
For Yarn => yarn run build
You also can check scripts in package.json file
You write down the below command being at the project root.
npm run build
First Install Vue Cli Globally
npm install -g #vue/cli
To create a new project, run:
vue create project-name
run vue
npm run serve
Vue CLI >= 3 uses the same vue binary, so it overwrites Vue CLI 2 (vue-cli). If you still need the legacy vue init functionality, you can install a global bridge:
Vue Init Globally
npm install -g #vue/cli-init
vue init now works exactly the same as vue-cli#2.x
Vue Create App
vue init webpack my-project
Run developer server
npm run dev
This command is for start the development server :
npm run dev
Where this command is for the production build :
npm run build
Make sure to look and go inside the generated folder called 'dist'.
Then start push all those files to your server.
One way to do this without using VUE-CLI is to bundle the all script files into one fat js file and then reference that big fat javascript file into main template file.
I prefer to use webpack as a bundler and create a webpack.conig.js in the root directory of project. All the configs such as entry point, output file, loaders, etc.. are all stored in that config file. After that, I add a script in package.json file that uses webpack.config.js file for webpack configs and start watching files and create a Js bundled file into mentioned location in webpack.config.js file.
I think you can use vue-cli
If you are using Vue CLI along with a backend framework that handles static assets as part of its deployment, all you need to do is making sure Vue CLI generates the built files in the correct location, and then follow the deployment instruction of your backend framework.
If you are developing your frontend app separately from your backend - i.e. your backend exposes an API for your frontend to talk to, then your frontend is essentially a purely static app. You can deploy the built content in the dist directory to any static file server, but make sure to set the correct baseUrl
npm run build - this will uglify and minify the codes
save index.html and dist folder in root directory of your website.
free hosting service that you might be interested in -- Firebase hosting.
if you used vue-cli and webpack when you created your project.
you can use just
npm run build command in command line, and it will create dist folder in your project. Just upload content of this folder to your ftp and done.
If you are using npm u can use npm run build but if you are using yarn you can simply run yarn build
If you want to create a build for a domain, you can use the $ npm run build command.
If you're going to build for a sub-domain, follow these instructions:
Create a file that's name is vue.config.js in the root
Write down the below code in the vue.config.js file:
module.export = {
publicPath: '/demo-project',
}
Now run $ npm run build
Note: Use your subdomain name instead of "/demo-project".
If you want to build and send to your remote server you can use cli-service (https://cli.vuejs.org/guide/cli-service.html) you can create tasks to serve, build and one to deploy with some specific plugins as vue-cli-plugin-s3-deploy
