I am getting error in console "You need to enable JavaScript to run this app." reactjs
Javascriptnode.jsReactjsJavascript Problem Overview
I am new to reactjs, I am working on a app. It was running fine, but when I've run npm run build command, I am getting error "You need to enable JavaScript to run this app.". I have made changes in server.js file even I've given "homepage": "./", but it did not solved my issue.
And I've checked by running laravel project, javascript is enabled in browser, also tried different browsers.
Someone please help me to overcome this error.
Javascript Solutions
Solution 1 - Javascript
I received this message when no proxy to the server was specified inside client package.json file.
"proxy": "http://localhost:5000"
(where 5000 should be changed to whatever port number the server was setup to listen to. In my case it also required server restart once added)
Solution 2 - Javascript
I had same problem. My workable solution:
package.json:
"homepage": "."
index.js:
app.use(express.static(__dirname)); //here is important thing - no static directory, because all static :)
app.get("/*", function(req, res) {
res.sendFile(path.join(__dirname, "index.html"));
});
Solution 3 - Javascript
I received this error because an API call that I was making was being blocked because of an invalid API key.
Solution 4 - Javascript
Try to run in other browser and see if it is working.
If it works there then please try below things and refresh your website.
- Right click and select Inspect.
- Go to Application Tab.
- Clear everything from local storage, session storage and cookies.
- Refresh your website.
This resolved similar issue in my case and hope it will work for others.
Solution 5 - Javascript
I had the same problem. In my case, the class name wasn't following the patterns (must starts with uppercase). As soon as I corrected it everything started to work well.
Solution 6 - Javascript
Go to your SignIn component or Register component, change the form tag
to a div tag OR prevent the form default i.e (e.preventDefault). Also make sure that Javascript is enabled in your browser.Solution 7 - Javascript
Just make sure that this route must be appeared after at all other routes
app.get("/*", function (req, res) {
res.sendFile(path.resolve(__dirname, '../client/build', 'index.html'));
})
Solution 8 - Javascript
I had some cookies set in the same url (localhost:8080), probably from a previous development, and it was somehow messing with my React project. I only found out because (out of despair) I tried with another browser and it worked. I deleted the cookies and it worked perfectly.
Solution 9 - Javascript
Also a react newbie, I hit this issue. Remembering to add ReactDOM.render(<MyClassName />, document.getElementById("root")); fixed it for me.
Solution 10 - Javascript
In your react project folder install serve if you haven't installed it before;
npm install -g serve
Then serve your project with a static server;
serve -s build
The build is a folder generated by 'npm run build'.
That's it! Visit
by default.
Solution 11 - Javascript
If you are facing the error "You need to enable JavaScript to run this app." in reactjs then 9/10 times there is an issue with your API call. Please cross check API url string, parameters, action type, endpoints, action names, controller names and API call status. You'll be able to find the issue. verify endpoint url again and again. You'll definitely find a solutions. Also check ur VPN access if you're able to hit the end point.
Go to console --> network tab and see ur API status
Solution 12 - Javascript
after adding proxy in react package.json restart the reacr server. This works for me.
