AWS EC2 react 应用程序部署有警告吗？ 怎么解决？

Question

I have ssh into the EC2 instance and pull the repo from my GitHub which contains my react app. Then I go into the folder in server and ran npm start trying to start deployment, but occurs these warnings, but when I run npm start locally, the web page shows correctly. (this is my first time doing the AWS deployment so I am not sure if this is ok even if with these warnings and if so what I should do next to make my web page appear?)

Answer 1

You can ignore the warnings, it doesnt affect your app running but it's worth to fix because it improves your app quality and remove some bundles that are not used.

To deploy your website, you have to use npm run build .

npm run build creates a build directory with a production build of your app.

After you successfully built your app, use nginx to host your build directory.

sudo apt install nginx

If you are on ubuntu, that will install nginx.

And update /etc/nginx/sites-enabled/default with the below content:

server {
        listen 80 default_server;
        server_name _;
        include /etc/nginx/mime.types;

        root  ABSOLUTE_PATH_TO_YOUR_BUILD_DIRECTORY;
        index  index.html index.htm;

        location / {
                try_files $uri $uri/ /index.html;
        }
}

Now restart the nginx and you will see your app running on your EC2 ip address.

sudo service nginx restart

These are not errors, so you do not NEED to fix them. They are (I think) ESLint warnings. They are meant to make your code better, but it will not cause an error when you run it.
