How can I get Parceljs to work with react? I'm using their example from their repo but it wont work.
https://github.com/parcel-bundler/examples
After I run 'npm start' it works and renders the page on localhost as expected but it will not work when I click the outputted file in /dist. So the page is just blank when I try to load it from dist/index.html. I also tried the production command from their website so it would stop watching the files but that also resulted in the dist folder loading a blank page.
How can I do this? Any help would be great. Essentially I want to be able to access the buddled files without localhost.
Thank you.
You're running the index files locally and the index.html is expecting the the css file and the js file to be at the root. When you're opening your file locally it is trying to find under C://
To get around this issue you have to edit the index.html unfortunately after you have compiled it. Here are three ways to get over the issue, method three focuses on fixing your issue but I would recommend methods one and two.
Method One
Install http-server by running npm install -g http-server
Go to your project dist folder via the terminal / cmd
Type http-server
Your project will open up in your default web browser
Method Two
Upload your application to a web server
Your application should run
Method Three (Not recommended)
Add the NPM script "production": "parcel build index.html"
Run production build by cd to your project and type npm run production
Go into your dist folder and open up the index.html in an editor
Edit the css file path from href="/main.--------.css" to href="./main.--------.css">
Edit the js file path from src="/main.--------.js" to href="./main.--------.js">
(NOTE: The React Add-on will not detect React when it is being opened locally, but the application will work fine.)

I'm trying to launch a React app (create-react-app) to GoDaddy using cPanel and I am having issues creating the correct build. I am setting the homepage in package.json underneath "name" and "version" (not sure if order matters here) like this:
"homepage": "http://mydomainname.org"
However, when I run npm run build, I get a message saying "The project was built assuming it is hosted at /. You can control this with the homepage field in your package.json.
Has anyone encountered this problem before?
That message is not an error. After you run the npm run build command a folder named build should appear and it contains your react app. You need to upload the contents of that folder to the public_html folder in cpanel's file manager. (Make sure you are uploading what is inside the build folder and not the build folder itself). Here is a link to a short tutorial
I have run create-react-app and started development on my app. yarn start works perfectly and the app runs in browser with several components and imported images. However, when I run yarn build not all of the images are moved to build/static/media (please see image below).
Folder structure and terminal output
There are no errors in the terminal output other than a warning about an arrow function which I have since removed with no success.
Is it still building an old version from when I only had panorama.jpg? Please advise.
You need to put your images to /public folder.
I'm new to yarn, nodejs and react apps. I've tried running the Sizzy app and it works on my local XAMPP server if I first run yarn start in the cmd terminal and then access via http://localhost:3033, but after a while I have to rerun the same command. I've tried yarn build and then navigating to the build directory but that just loaded a page with a header, it didn't have the same functionality. And the contents of the build directory looks very similar to the contents of the public directory anyway.
I've had a look at this SO post and this one but still unsure why I need to run yarn start everytime.
UPDATE:
I'm still not sure how node, react, and electron fit together and why each is required, much research and learning still to do! Rather than a 'react app' I believe I'm looking at an 'Electron app'. I think if I run the command npm run package-win then I think I should get an exe file and some dlls. But how to instead setup for running on an Apache web server without having to start using the command line, or would you just have to build it with different architecture?
Starting to get a vague understanding from reading this.
If you used the npx create-react-app <app-name> then you just have to change the "start" script in the package.json file as "serve -s build". Run yarn add serve to add For deployment, Heroku is a good choice. Create a Heroku app and connect your git repo to the newly created app. Then go to the deploy tab and deploy your branch.
I'm newbie on react, I did 2 paged website for exercise, all is working well on my localhost.
But i'm confused about how upload project to my linux server.
What i did ?
I create react app via terminal with this command :
create-react-app react-demo-project
Terminal create my project and in project root i have node_modules directory.
so here is i have some questions:
1- React project will work normally on linux hosting?
2- I need to all my project upload to ftp? Because there is arround 20.000 file in node_modules directory.
With this command build your app :
npm run build
Build folder has created in your project directory, open index.html in your browser and check output...
If you saw a blank page (after build and opening index.html) , you must change the main js file path in the index.html :
default is : src="/static/js/main.ddfa624a.js"
change to : src="./static/js/main.ddfa624a.js"
I changed js path and this worked !
create-react-app has a command to bundle your app to a ready to deploy state.
npm run build
This command will bundle your app in /build folder. With the contents of this folder you can deploy your app in any hosting environment. You don't need to install your packages and libraries manually when you use this command. More information about using this command and deploying your app in different hosting environments can be found create-react-app README
Deployment
npm run build creates a build directory with a production build of
your app. Set up your favorite HTTP server so that a visitor to your
site is served index.html, and requests to static paths like
/static/js/main.<hash>.js are served with the contents of the
/static/js/main.<hash>.js file.
1- React project will work normally on linux hosting?
Yes, it will work in all webservers, unless you have server side rendering (SSR)
2- I need to all my project upload to ftp? Because there is arround
20.000 file in node_modules directory.
Files in node_modules will NOT go to your web server. These are development dependency files used only during development.
Run npm run build
This will create a folder called build in project root. This will have all html, css , images and js files
Copy all files and folders in build folder to your site root.
If your site has to be hosted in a sub folder in root you need to do the below, otherwise you will see a blank page. This is because your static files (css, js etc) are not loaded correctly.
Open package.json
Add a new entry homepage: /your_subfolder/
It will look like this
Now do steps mentioned above and your site should work fine
Add this line to package.json:
"homepage": "./"
That should make it work without the need to adjust index.html after every build.
I have tried every tutorial I could find to try to make a HTML/JS project with Angular 2 working on NetBeans, but none have worked. Maybe is my npm that is bugged (search, for example, doesn't work).
The node_modules folder that is created with npm install is grey on NetBeans and have some errors in some files (I don't know if this is normal). Any .js I try to import from node_modules folder gives the error Failed to load resource: net::ERR_EMPTY_RESPONSE / Uncaught ReferenceError: System is not defined.
Does anyone have any idea what could I be doing wrong? Or does anyone knows any tutorial that have the code to download so I can compare with what I'm doing and see what is the correct? Every tutorial I have found doesn't have any code to download, just some pieces of codes in the page for explanation.
Sory if this isn't a good question, but I have been trying to make this work since yesterday without success and I'm completely out of idea.
First I recommend to upgrade to the last version of NodeJS and NPM, to minimize the errors in your node_modules folder
Install the Everlaw's Typescript plugin from https://github.com/Everlaw/nbts/releases . If you are using Netbeans 8.1 I think you can install it directly from the Plugins installer. I'm using NetBeans 8.2 and there is no problems installing the plugin manually.
Then on NetBeans go to Tools -> Options -> HTML/JS -> Node.js and write the right Node and NPM Paths and Sources, I would recommend check-on the three check-boxes in that panel.
For a quick start try the QuickStart demo from the angular.io page, it is not necessary make any change in the package.json.
The first time I tried to debug an Angular 2 application I put the index.html file directly in the project folder in order to do not make any changes in the index.html script sources nor change the project files structure but you need to change some properties of the project:
In the project window right click the project and select properties.
In sources change the Site Root Folder using the Browse button and select the project folder (You can ignore the warning that appears).
In Run select Run As: Web Application.
I recommend select Browser: Chrome with NetBeans Connector
Using the Browse button go to the project folder and select index.html as your Start File.
Select Web Server: Embedded Lightweight.
And finally in Web Root write /Your_Project_Folder
run npm install from NetBeans
Click the run button and your web application must open in chrome, if you edit your html or typescript files and save them you could see the changes in the browser in real time without re-debuggind your application and can use the Browser DOM window to explore your elements created from Angular 2.
You still see some errors in your files because NetBeans is not fully compatible with the HTML Angularized syntax. But it runs flawlessly.
You can also run the start script directly from Netbeans to run your project using lite-Server.
Screenshot NetBeans - Angular 2
I would recommend you to install the angular cli: npm install -g angular-cli#webpack
Fore more infos regarding this tool, take a look here: https://cli.angular.io/
Then create a new Angular2 app with ng new <app-name>
This will create a complete and working Angular2 application in the current folder.
cd <app-name> and start the app with ng serve.
Check your new created app in your browser on localhost:4200.
If this works, you can try to get started with your NetBeans! :)
