Within my package.json, I have the following script:
"dev": "webpack-dev-server --config webpack.dev.js --progress --port ${getPort()}",
I've also installed a package called get-port, which allows me to set a default port and obtain an alternative if the default is in use.
I'm interested in utilizing this dependency to retrieve the port for the script mentioned above (where getPort() is indicated). How can I execute JavaScript inline and capture the returned value from a function?
Avoid using random ports, especially if you are connecting with other services such as the Facebook API. Instead, consider implementing a gulp script to manage the process on your specific port.
Have you thought about setting it to automatically assign a port in webpack? Check out more information here.
If you prefer a customized approach, one option could be to create a gulp script that uses 'get-port' to find an available port and then launches the ng serve command accordingly. Make sure to have gulp and get-port installed before running this code snippet:
const getPort = require('get-port');
const exec = require('child_process').exec;
var gulp = require('gulp');
async function serveMe() {
gulp.task('serve', function (cb) {
exec("ng serve --port " + await getPort(), function (err, stdout, stderr) {
console.log(stdout);
console.log(stderr);
cb(err);
});
})
}
exports.serveMe = serveMe;Update your package.json file:
"start": "gulp serveMe",Typically, the suggestion would be to utilize the CLI version of this tool, allowing for easy integration into shell scripts. However, as it appears you've faced challenges installing get-port-CLI, here is an alternative approach:
You can execute code inline using node -e <script code>, specifically with
require('get-port')().then(console.log)webpack-dev-server --config webpack.dev.js --progress --port $(node -e 'require(\"get-port\")().then(console.log)')
