React Proxy | Easiest Fix to CORS Errors
ฝัง
- เผยแพร่เมื่อ 4 ก.ค. 2024
- Proxying API Requests in Development using Vite, Parcel, or Create React App. If your plan is to host your react app from the same origin as your web server, then this is super helpful. Conveniently, this also avoids CORS issues. I'll also show you how to deploy your react app using your express server and railway.

sir, 4 hour,its 8:25AM, i was trying to solve this from around 3:30AM. you cant imagine how happy i am right now to find those 4 line of code in ur first 10 sec of video...... i love you man even turned on bell icon cz u saved my project, i was about to delete it
it took me two days
this is exactly how i feel right now😁😁
Unlike every other youtubers who says bunch of nonsense and non related things before giving the actual information for which we came for, You gave the most important information in the first 10 seconds and proceeded to explain it later. You have our respect.
This entire list of react focussed videos is great, It is obvious you spent a huge amount of energy on taking us along on the learning curve- just compare the first couple of videos to this, it's a great expansion building on the previous knowledge!
This video really blew me away with the quick deployment on railway, that's awesome.
Also loving the quick snippet at the start showing the main point!
I was so stressed out about the whole CORS issue, and this, this is just gold. Straight and to the point explanation! Really appreciate the work!!!
This clears up a lot for me man. This is the first time I try to make a fullstack app and all these deployment issues are confusing af. Thumbs up for you 👍
Really awesome video. Telling the solution at start and then it's upto the user to say. Love it man! Hope to see more youtubers be this thoughtful
Thank you so much, after a week of search i got my issue fixed and finally the data renders on my frontend up! Keep up the great work! Thank again!
bro after 2 and a half hours of struggling around , i had lost my hope. and the i decided to watch this full video as my last tether to sanity. and that stupid failed to fetch error is finally gone. thank you dude. god bless you.
Thank you so much for this tutorial, I've searched lots of videos and site but none of them specified exactly how to solve it in vite. really appreciate it Sam
I needed a solution as fast as possible, I looked a lot of videos that didn't help me, but this one in the first 30 seconds gave me the answer, thank you
you make videos of things I've wondered about at some point during my learning process, so good! this cors issue was something I fixed using an extension without really paying attentions to the whys and how's
I've been looking for a solution about the proxy in vite-react for days, then this video solved it within 20 seconds. Thanks a lot!
I dont really know u and this is my first time of watching ur video but ur video just saved me after 4 days of trying to connect my vite React project with my node js without using cors.......U are a life saver for that am subscribing......thanks again
Can't thank you enough brother. After almost 4 hours of frustration, got the appropriate solution. Also, CORS package wasn't fulfilling the purpose, as suggested by other channels.
I never thought that I can solve my intital (proxy setup) and final (deployment) problems by just watching one video.
Spent all day trying different way to deploy my project but lost functionality after deployment. Finally deployed using the process in the video and everything is working sooo fine and it's soo easy. I can't thank you more, u really saved my day here and explanation is on point that made me think like, "what the hell, I understand everything this guy saying" . THANK YOU SO MUCH
The first video I have ever commented on. CORS was driving me nuts. Thank you!
God bless you man!!! Thank you very much for sharing what I was looking for in the first 10 seconds of the video instead of scattering it throughout the video... ❤
I spent a whole night trying to circumvent those cors issues. Thank you very much. Now I'll go get some sleep
I really like this pattern for building full stack react and node applications. Thanks for the video.
This video clears all my doubts about proxy server. amazing content!!
Thank you so much , you can’t imagine how grateful I am for this clearly instructed solution,I’ve been stuck on this CORS issue for 3 days and went through a lot of solutions and videos but yours is what worked best for me 🙏 thank you again
Amazing dude, i was stuck for a whole day figuring out whats wrong.
Just wanted to say this helped me in a bind. Thank you!
i literally spent 2 days on cors and hosting but you made it in 15 min thanks man🥺🥺🥺
Wow, that was fast mate. Thank you Sir :)
thank you for this... I have been searching for this for 4 hours ...
thank you for getting to the point from the start [subbed]
Dude, this vid saved my butt.... spent ages trying to solve a proxy issue... Sub'd!
omg this is amazing XD immediately subscribed!
What a legend , i've been stuck with this for 3 days . it almost seemed impossible to solve then this video showed up when i was just scrolling 😄
Thanks very much for the video! Got a bit confused why some other tutorials like uploading an image to S3 didn't work for me with the way you did it, but it was because of the missing proxy haha
Thanks you ^^,I find this pbm with my Java Spring api and Vuejs, after your tutorial it's work. Your the best ^^

Thanks a lot, great video :)
Hi Sir. The tutorial is great, but I got catch for the plugin that helps you to complete code, I think you call it Copilot, but I see so many copilot on VS code. Could you be specific which one are you using?
Tnks bro its working very well, keep going👍
Great vids, one thing is there a way to automate the build process?
thank you so much! perfect!
Wow I can't ask more than this
great vid 🤌
Thank you, you have recived my sub and like
Thanku , after wasted of 2 hours i found the solution of this problem thanku😊
Thank you for such a clear explanation on CORS and how to resolve related errors. Im facing slighly more issues as I have containerized the frontend react app and backend spring boot api and seeing this CORS errors. I tried to add @CrossOrigin on the spring boot endpoint and also tried to add the serverUrl on the axios.post call. But it is still coming with error like u explained since the ports are different. Both containers are deployed on an EC2 instance using docker-compose remotely. Any recommendation as to how to go about resolving the issue.
Much appreciate it.
Thanks that's a great helpful information
thanks, it helps a lot
Thank you so much mate
The projects I work normally frontend and server are in complete different repos. So the approach in this case would be to add both localhost and production host at server cors config ?
Thank you so much from Pakistan!!
Thank you bro!
love it!
Thankyou so much!
which extensions are you using for auto complete? nice explaination btw.
Thanks I was able to fix a problem with this
great video, thx
Thank you Sam :)
I have a React js (axios) application on the client side and Node js (express) on the backend. I use aws iis ec2 as my hosting server. All works fine both in development and production, except when I connect to Veepn Chrome (from production) then my token header is not found. I don't use proxy, could this be the issue. I would really appreciate it if you could help me.
thank you thank you very much!!!!!
What would be a suggested way to do this?
Great! Thanks.)
real hero
Amazing
Thack Thank Thank you very much ! 🥳
Great but doesn't work for POST requests. All Post requests I make is somehow changed to a GET request by the proxy
thank you bro
Thank you sir
Thank you
hi, how can i use 2 proxies in create-react-app?... by the way nice explanation.
Thank you man
You're welcome!
should i remove the proxy in prod ?
THANKS MANNNNNNNNNNN
i am just using normal react app even though i set it is still showing those error i am using vercel to deploy is there is any other way to fix those
Config done run on localhost then work. But when deploy to hostname server VPS then not work. It's alway show error CORS. You can help to me root core ?
Thanks
why do I need that proxy? why it would not work with localhost. Sorry - I am new in the field.
Nice
i add proxy on packaj.js and when i run npm start i get this
Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
- options.allowedHosts[0] should be a non-empty string. how i can solve it , i spend 3day on it
Thank you so much
You're most welcome
thank you
Does it work in SSR?
Thank ♥
Thanks , so we can create proxy in next js too?
Yes you can, you could use http proxy middleware, or next js rewrites. However, deploying a next app is usually much different than a "traditional" react app and the plan probably won't be to bundle your client side react app with your server like it will with a react app that isn't using next.
In next you're probably just going to use the next api or you're going to render your components on the server, or both. If you have another server that you're making API calls to, you might want to go down the CORS rabbit hole, but maybe using a reverse proxy like nginx.
Thank you, Sam, for explaining that we have our own backend, but what about the case in which we are using third-party API?
This method only works if you're serving your react app from the same backend that you're making requests to. So you wouldn't be able to do this with a third party API, but those should already have the correct CORS configurations to allow you to make requests.
@@SamMeechWard The API endpoint I was using didn't have CORS configured so I used a proxy to fix the issue
Thanks
@@SamMeechWard Thank you so much! Glad to have found your video and it helped me a lot. The only issue I am facing now is that this way, other routes (e.g., /admin) won't work after build - I am seeing "cannot GET /admin" messages. Routing works perfectly fine in development and I am using React Router Dom v. 6. Would you be so kind to explain this or point in the right direction? Thanks again!
EDIT: Think I just solved it by adding
app.use("/admin", (req, res) => {
res.sendFile(path.join(__dirname, "dist/index.html"));
});
to my server. Not sure whether this is a correct approach, but it does the trick. Still, Would love to hear how you would solve this. Thanks!
@@mubashirwaheed474 Have you fixed the issue? I have tried using the video's fix but it does not work in Production.
@@kenthugoin order to fix my issue I used the netlify's serverless function to create a proxy (express server through which request is made to the api and then proxy -backend- send the data to the frontend
How about using public API?
Cool
Great
jeez man, you sure have huge eyes
P.S. Thanks it helped!
Always nice to meet a fan
What does it mean if I'm getting error 301?
vite proxy doesn't change axios configuration
