I am trying to call my API through proxy. It works fine locally. But while I build and upload to my server it does not work.
in my vue.config.js file :
devServer: {
proxy: {
"^/rest": {
target: 'https://v1.quant-ux.com',
ws: true,
changeOrigin: true,
pathRewrite: {'^/rest' : '/rest'}
},
}}
The devServer only runs in local environments (on your machine during development). It's a separate process from your build, so you can't deploy a Vue app with a built-in proxy server.
Your options:
Rewrite your URLs to the proxy target (e.g., a build script/plugin).
Run your own proxy on the server (assuming you have control of it).

On my local machine, my React front-end runs on localhost:3000 and my Node/Express back-end
runs on localhost:8080.
Inside webpack.config.js (for my front-end), I use proxy so my front-end can fetch() data from the back-end via the url /api
module.exports = {
//...
devServer: {
proxy: {
'/api': 'http://localhost:8080'
}
}
};
After I deployed my app to Pivotal cloud, the proxy configuration no longer works because it's set to localhost.
How should I configure it so that it's not hard-coded to localhost?
How to update React localhost (127.0.0.1:3000) to another domain (local.example.com)
Might be too late on answer... First configure your hosts file to add local.example.com as your local envir(windows) see link
devServer has a host property
devServer: {
host: 'local.example.com,
port: 80
}
setting the port on 80 will allow you to visit http://local.example.com
I would like to integrate Vue in my .net MVC project. I've installed Vue using the CLI and added the following vue.config.js:
module.exports = {
devServer: {
proxy: {
'/': {
target: 'http://mvcsite.local',
changeOrigin: true
}
},
disableHostCheck: true
},
runtimeCompiler: true
};
The proxy works fine, except that a request to the root http://localhost:8080 (which the dev server runs at) serves the index.html generated by Vue, rather than proxying the request to the root of http://mvcsite.local. How do I proxy that particular request?
As indicated in your comment, there is an open issue on github for this, so currently there seems to be no fix. In my case (ASP.NET MVC 4) I solved the problem using a workaround. I simply move the root dir to /Home in development environment. Of course your server backend has to support this scenario, but that's usually the smaller problem. My working vue.config.js for #vue/cli 3 looks like this:
module.exports = {
publicPath: "/Home",
devServer: {
publicPath: "/Home",
proxy:
{
'^/Home/*': {
target: 'http://localhost:50353/',
ws: true,
changeOrigin: true
}
},
}
The following Webpack dev server configuration works without errors on macos system:
module.exports = {
// [...]
devServer: {
host: 0.0.0.0,
port: 8080,
contentBase: "/dist",
hot: true,
inline: true,
watchOptions: {
poll: true
}
},
// [...]
}
I can access the web app from mobile device connected to the same network and using the local ip of the machine (192.168.1.65:8080).
The same configuration does not work on Windows, it seems it can't open 0.0.0.0 on the browser. But using any other ip other than 0.0.0.0 does not let access from mobile devices. Does anyone know how to fix this issue on Windows?
0.0.0.0 is a non-routable meta-address used to designate an invalid, unknown, or non-applicable target (a ‘no particular address’ place holder).
I am trying to get my fairly typical JavaScript (React) app to run in dev mode on AWS Cloud9. I successfully cloned my repo (using https ugh), installed my npm packages, and can run scripts in the console. However, I don't know how to run and access the app in dev mode. There are a plethora of docs but they all seem to dance around the running part. My guess is I need to somehow set a custom host and port, but I also need to find what URL to use to see the app running.
Here is my devServer config:
devServer: {
// Display only errors to reduce the amount of output.
stats: "errors-only",
host, // Defaults to `localhost`
port, // Defaults to 8080
overlay: {
errors: true,
warnings: true,
},
}
If anyone comes across this, I wanted to share my solution because I know how frustrating this can be:
First, create a script in your package.json file:
"start": "webpack-dev-server --open"
Then, add the following to your Webpack config file:
devServer: {
contentBase: path.join(__dirname, 'dist'),
host: '0.0.0.0',
port: 8080,
compress: true,
}
Then, open the terminal in AWS Cloud 9, and run the script:
npm start
Finally, click on the link in the terminal: "Project is running at http://0.0.0.0:8080/" and your app will show in a new window.
**If it doesn't work, don't forget to allow port 80 on your Cloud 9 Security Group: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/working-with-security-groups.html#adding-security-group-rule
If you want to view the project in the preview pane, you can add the following to your devServer config:
disableHostCheck: true,
However, it's important to note that when set to true, this option bypasses host checking. THIS IS NOT RECOMMENDED as apps that do not check the host are vulnerable to DNS rebinding attacks.
1) First thing you need to do is to run react app on port 8080. You can do this by setting environment variable PORT to 8080 and then just starting react dev server from AWS Cloud9 terminal.
export PORT=8080
npm start
For details look at this discussion on GitHub.
2) After starting your application you can preview it by clicking Preview -> Preview Running Application at the top of AWS Cloud9.
For more details check this AWS Cloud9 doc
In webpack.config.js:
devServer: {
historyApiFallback: true,
contentBase: './',
host: process.env.IP,
//https: true,
port: process.env.PORT,
"public": "your-project.c9users.io" //no trailing slash
},

I have a local Node.js server running on port 3000. I have another dev server for front end using webpack, running on 8080. Node is connected to MySQL server. I want to send data from my Node to front end. My project structure looks like this:-
SampleProject
-> BackEnd
-> FrontEnd
Should I use CORS node module? If not how should I send the data?
The easiest way would be to use webpack-dev-server proxy option to proxy requests from webpack-dev-server (8080) to Node (3000).
Example config:
{
devServer: {
proxy: {
'/api': {
target: 'http://127.0.0.1:3000'
}
}
}
}
