I am new on Next JS, I have created a small application. It is using API calls and more features.
During development, Using the command as npm run build I am able to create .next folder as build and using npm run start I am able to run that build.
Now the client is asking for build, so what should I send to him? Either complete project and ask him to do the
npm run build and npm run start (which I don't think so)
or only the .next folder. But how he will run this build?
Open package.json in your editor and add the following export script to the file:
"export": "npm run build && next export -o _static"
run this code in the terminal:
npm run export
Open _static folder and there is all of your file.
Some possible ways of sharing your project:
You can easily build and host your project with services like vercel or netlify. Easy and quick. Check out the vercel CLI in particular.
Your client can clone the git repo, install all dependencies, run build, and run start. This'll start a production server. Check here: https://nextjs.org/docs/api-reference/cli#production. Bad idea if your client is not a dev.
You can build your project and send the output to your client, which he/she can then view by spinning up a server (python simpleHTTPServer, Mamp). Also a bad idea if your client is not a dev.
Long story short, host your project somewhere and send them a production URL.

I'd like to run a create-react-app (5.0.1) with react (8.0) as a local file. i.e. Not served.
Is this possible?
I've built a basic app and run the build command. Inside the build folder I've opened the html file directly from the browser. I get the following error:
Loading failed for the <script> with source “file:///static/js/main.eb2f7516.js”.
Technically react should be able to do this, right?
If you look at the create-react-app documentation you'll see one suggested method
is to use serve.
A convenient way to test your build is to run the npm run build command, and then run npx serve -s build while in the same folder. This should now serve your static site on port 3000 by default.
I'm using create-react-app. When I run npm start (react-scripts start) it continuously builds the changes for me and does it magic. But what is the output folder for that? I know when I build it manually where the files go.
I want to use firebase emulator to serve the current version (the continuous build) of my react all but I don't understand where's the output folder or how to achieve it.
You could try this package https://github.com/Nargonath/cra-build-watch
Install it and add the script to your package.json
{
"scripts": {
"watch": "cra-build-watch"
}
}
and run it
npm run watch

and if you go to the react repo issue linked in the article you would find more workarounds
tl;dr
run npm run build, not npm run start
More Detail
react-scripts start runs webpack-dev-server internally. As a default setting, webpack-dev-server serves bundled files from memory and does not write files in directory.
If you want to write files with webpack-dev-sever, you could set writeToDisk option to true in your dev server configuration.
However, I dont think this is what you want to serve on firebase emulator. Webpack-dev-server does not build optimal app for production, and you also need to use react-app-rewired to customize dev server configuration in cra template.
What you want to do is npm run build to run react-scripts build, which builds optimized production app in /build directory.
I created a ReactJS app using create-react-app and it works great when running from NPM START with the address of localhost:3000, but after I use npm run build and run index.html from the Build folder, the JSON never loads from the map function. Is there a step I am missing?
All help is appreciated.
Thank you.
npm run build only generates the build files at build folder , to run the project in production mode you need to upload the build folder files to a hosting provider or use some kind of local server to serve them .
There is a vscode extension which can run production files locally see the extension here .
I have created a test React application and I started it with the create-react-app. I am starting it with with yarn start, but that starts the debug version of the application. I did npm run build and it created the build folder, however when I do yarn start from the /build folder, it still starts the debug version of the application. I need this for testing performance with the optimized version. How can I solve this?
You can actually use static server to run build version of your app. It's doable with serve. You can test it with:
npm run build
npx serve -s build
Navigate inside the directory of your app first.
According to the official create-react-app website. When you run npm run build or yarn build you create a build directory with a production build of your app.
After running the command above the next thing you can do to check the build version of your app is to install serve to serve your static site on the port 5000 by default.
npm install -g serve
serve -s build
This will copy the link to your clipboard that you can paste in your browser and see the build version of your app.
You're trying to move from a development build to a production build with create-react-app you need to deploy it using a web server, I would recommend using Heroku or a droplet or you can use Netlify which has a simple set up procedure using the below commands:
cd project-name
npm run build
npm install netlify-cli -g
netlify deploy
Follow command line prompts and choose yes for new project and ./build
as your deploy folder and voila you have a production React app!
You can host the app locally using apache, nginx, express
If you want to run your app in browser with build files served locally from the filesystem (i.e., without a web server), you can put this in your package.json:
"homepage": ".",
Now
build your app with npm run build.
launch <your app>/build/index.html in the browser.
Note: This solution is not suggested if your app (or some routing library) is using the HTML5 pushState history API. https://facebook.github.io/create-react-app/docs/deployment#serving-apps-with-client-side-routing
Hi everyone I know its simple question but I am new the angular development.
I have angular projects but I cant run.
I know npm using on console, I tried many times npm run, npm instal on my main directory.
So, how can I run my angular project on the console?
If the project is using Angular Seed or is similarly configured, you can use
npm start
to install dependencies and start a running http-server on port 8080 (by default).
If you project has a README or package.json file, it might give more clues.
Otherwise you can just serve up the application with http-server:
npm install http-server
http-server .
Asume you are using NodeJS as a server side, try node [your-application-main-js-file.js]. For example node index.js. But it depends on what back end environment are you using. Angular is just a front end library/ framework. It should be tested on browser not in your console.
