I am trying to run the node server by ts-node-dev and restart on any any changes in specific files. It is restarting on any changes made to ts,js files however, it is not restarting on changes to graphql files. Any suggestions?
"scripts": {
"start": "tsnd --transpile-only --rs ./src/microservices/index.ts --watch--extionsions
ts,js,graphql"
}

When I save changes to my client-side code, the browser hot-reloads as expected. But when I make changes to my server code, no hot-reloading occurs. This is a problem because we want to just run 1 command (i.e. npm start) to launch our React webpack-dev-server AND our API server, and rerunning the entire npm start to manually relaunch the server after changes is slow (because it unnecessarily relaunches the React dev-server as well). Also sometimes we forget to relaunch the server code, so in reality it should just hot-reload anyway.
I've looked across the internet and surprisingly can't find any straightforward solutions. I feel like I shouldn't have to eject the entire project and go deep into the webpack configurations to get this to work.
This is what the npm start portion of my package.json looks like now:
"scripts": {
46 "start": "concurrently --kill-others \"react-scripts start\" \"node server.js\"",
...
}
Is there perhaps a way I can do "react-scripts start" with a different target or something?
I am very new to server side scripting. And I am using NodeJS. My Problem is that after adding some new features to the app, i.e. after changing the code, these changes will be applied only after restarting the server. Till then NodeJS behaves so as though I hadn't changed anything. So for instance if I add console.log("works") and don't restart the server, then it hasn't any effect.
I am using Nuxt.js, which is actually the Vue.js framework but with additional and very usefull features mainly for server side rendering. I didn't integrate the express.js at the beginning of the project, beacause it wasn't planned to write any server side code. So I am normally exporting express and using it, which is pretty fine for me, since I need just a couple lines of code to use the NodeJS file system.
So, as it is pretty hard to code, if I should restart the server once I changed anything, I want to ask you if there is any solution to this problem.
Use nodemon
step 1 : npm install -g nodemon <- this will install nodemon globaly in your system
step 2 : change your start script within package.json
"scripts": {
"start": "nodemon fileName" <- like this //filename is you root file which starts the app like app.js
}
step 3 : npm start
This is already build in into nuxt. You just need to run it in dev mode, not in production.
E.g. for dev with change monitoring
nuxt
For production without monitoring
nuxt start
So in this particular case the following changes to the "scripts" in package.json have solved my problem.
"scripts": {
"dev": "nodemon --watch api --exec \"nuxt\"",
"start": "nodemon nuxt",
}
The following link could also be usefull to you.
Install nodemmon in your application to allow live update npm -g install nodemon
and add the following codes inside your packages json file :
"main": "app.js",
"scripts": {
"start": "node app"
},
on your command line, just type : start
I'm a Java developer but I have to try and debug a Node based application which runs inside Electron. I use IntelliJ IDEA for Java development/debugging and have WebStorm for which I want to debug the JS application.
As a Java developer I am used to starting the JVM/Tomcat/OSGi container in debug mode to which I can attach IntelliJ as my debugger. This allows me to dynamically add breakpoints without modifying code in IntelliJ. I want to be able to do the same with the Electron application but I haven't been able to work out how to do this.
I have tried starting Election with the --inspect option as detailed here but cannot attach WebStorm to it. I've also tried setting up a run time configuration in WebStorm itself which works as far as starting Electron but terminates with the error 'connection refused'.
I've also used this and this to try and attach a debugger but to no avail. I also have to work on Windows so I'm facing having to deal with inadequate tools to determine if Electron is listening on a port.
Update
I can't put complete code here but I would start the application with:
npm run dev
And this is the relevant part package.json in the root folder of the application but WITHOUT any debugging options specified:
"dev": "concurrently --raw --kill-others \"npm run dev-server\" \"npm run start\"",
"dev-server": "webpack-dev-server --hot --inline",
"start": "cross-env WEBPACK_ENV=dev electron .",
The application starts up i.e. the Election window appears but terminates before it is completely rendered. I can't say for sure how far into the start-up it gets before failing.
Update 2
I've modified the package.json file dev and start lines to:
"dev": "concurrently --raw --kill-others \"npm run %NODE_DEBUG_OPTION% dev-server\" \"npm run %NODE_DEBUG_OPTION% start\"",
"start": "cross-env WEBPACK_ENV=dev electron --inspect=5858 --remote-debugging-port=9223 .",
But still get Connection refused.
To debug Electron main process, you need using Node.js run configuration; for render process, the Attach to Node.js/Chrome configuration is required.
Please see https://blog.jetbrains.com/webstorm/2016/05/getting-started-with-electron-in-webstorm/ for more info
I found that WebStorm can debug the main process properly if electron is started with the flag:
electron . --serve --inspect-brk=5893
Note the 'brk', it stops the process until a debugger is attached.
Then I just created a run configuration (Attach to Node.js/Chrome) and specified the 5893 port, telling to reconnect automatically.
I am new to nodejs and this is first time I am using nodemon. I am using nodejs on windows. I have got following in my package.json file
"scripts": {
"start": "nodemon ./bin/www"
}
And I use npm start from command line to start my express app. The process start with a default port which is annoying. But what is even more annoying is that every time I change a file nodemon restarts the application, sometimes on an entirely different random port number. I tried changing the script section in package.json file to the below but that did not make any difference
"scripts": {
"start": "nodemon ./bin/www 3000"
},
From the comments it seems you're specifying the port through an env variable, let's call it EXPRESS_PORT. The node process doesn't inherit it when you start it with npm because npm start creates a new shell with its own environment. So you end up passing port undefined to express. That makes it bind to a random free port. To fix this you can set the variable in the start command:
"scripts": {
"start": "EXPRESS_PORT=3000 nodemon ./bin/www"
}
Or you can export it from your shell with export EXPRESS_PORT=3000 and then run npm start. If you do this you need to make sure to always export before starting the server, so you might want to place the export in ~/.profile or ~/.bashrc.
For example, if your package.json file contains:
"scripts": {
"start": "make start",
"test": "make test",
}
^ Will nodejitsu be able to parse and implement "make start"?
If the server.js file contains the static file path of the following directory then only the makefile functionality will work.
Nodejitsu should parse this just fine. Just be sure that you are calling node <app file>.js in your Makefile somewhere, or you change it to make start && node <app file.js>. Nodejitsu uses npm start to start your application, so the Makefile exiting without starting the app would cause the deployment to fail.
