I am glad I've landed on this page. You cannot image the hours I have spent looking for an answer to this. Everybody was saying to add this to my webpack.config.js to fix the problem:

devServer: {
historyApiFallback: true,

But it didn't.

By the way, the web.config you are referring to has to be copied to the directory where the index.html and main-bundle.js which is the root directory of the folder where the files are hosted on IIS. The name of the js file may defer based on your what your configuration is. In my case this is what I have in my webpack.config.js:

output: {

filename: '[name]-bundle.js',

Thank you so much dude. Keep up the great work. Let me know if I can pay you for a fancy cup of coffee.

Can you please provide the screenshot of the error you are facing? Also Could you please make sure that app pool on which your app is running should be run on administrator account so that it can access our files.

Hi Sumit,

I forgot to add the URLRewrite module on iis, its working fine now, thanks a lot for prompt response
But now I am facing below problem ....

My front-end application(React) and back-end code(DotNet Core), I have kept in the same folder..

If i use 2 differetnt pools --one for Front-end application and another for backend application, then, when the application runs..all the apis fail with 403.18 forbidden error

If i use same pools for both, then the application runs....the apis give status as 200, but the response is in text/html form .....

I am tried various links--like trying DefaultAppPool, but still the issue remains ....

One more thing , if i place my front-end in one folder and call api from another folder, then there is no error ..the application runs fine ..and apis are also working properly

I am very confused....I dont knwo wht is the problem...iis or React
I have uploaded 2 images, with this question, hope you are getting the images too
Please tell me if i should send you any other info, which i am missing

Pleas help

Hi Sumit,

Thanks for the reply.
I was able to solve the issue. I was giving Capital letters for the api, that's why the problem.

Hi Sumit,
First I want to Thank You so much for your Post on “How to deploy React Application on IIS Server”. Took my a week to find a good article and yours worked first try!!!!!!.

Everything works except when I try to refresh on urls with parameter variables.
For example domain.com/user/2

Have you figured out how to get that working for you?
If so would you please share. Thank you so much!!!!

I created a very simple app.js file below to illustrate.

The main reason for getting this error while deploying react app is when you do not install a URL rewrite module.

Nice work, thank you, I had some problems running the application, some images were not loading properly, after some investigation, I identified only *.webp image files weren't loading properly... so I found on StackOverflow the following tags that should be inserted on web.config file

    <staticContent> 
        <mimeMap fileExtension=".webp" mimeType="image/webp" /> 
    </staticContent> 
Enter fullscreen mode Exit fullscreen mode

I need to host my react app inside a subfolder. localhost:port/subfolder/index.html

You have to add a new website and select the default app pool instead of creating a new one. please make sure that default app pool should be run on administrator account so that it can access our files. Let me know if you face any other issues.

All worked well but now i am not able to call api via axios or fetch i had add my api main url in package.json in proxy setting .... can you help me what should i do

Collapse

Sumit Kharche Author • Edited

The proxy feature isn't meant for production. Proxy is most suitable in the Development environment but when you deploy your app with prod mode on a web server then you need to do it in different ways.
Few links for your references:
create-react-app.dev/docs/proxying...
github.com/facebookincubator/creat...

One way you can do it by using the environment variables.
create-react-app.dev/docs/adding-c...

so for development create file .env.development outside of src folder and add your API URL like:

REACT_APP_API_BASE_URL='<your local api url>'

For Production create file .env outside of src folder & add your Prod api base url like above.

once you configure your API URLs you can simply use it in your as App as below:

process.env.REACT_APP_API_BASE_URL

I hope this solves your problem. Please let me know if any queries.

With build you refer to the main.js? Im trying to connect a React App to my Windows Server Service but i dont know if i have to mount my React App to connect

Collapse

Sumit Kharche Author

If you build your React App using npm run build command or whatever command you have for building your app in production mode, it will bundle your app and put it into a build folder. So when we have to deploy this app into IIS then we have to give the path till build folder which contains index.html file.

Thanks for sharing.
I followed the steps you stated.
I can access the react app on the windows server via localhost:9000
But I can not access via server_ip:9000
could you help me to figure it out?

and if your server is at your home, u should open port on your modem too
