Oh no oooooops! Good catch! You are 100 percent right, I clearly wasn’t paying attention hahah. I will pin this so people know not to bother writing 8000 when you can just use the constant PORT. 🙌🙌
Extremely useful tutorial, thank you. Finally someone who understands a newbie's need for explanation of the fundamentals that seem so confusing when trying to figure it out for ourselves.
I've been searching for a clear tutorial like this for weeks, thank you so much! The CORS issue has been driving me crazy. I enjoy the sound of your voice, as it makes it easier to concentrate, and I loved the way you explained everything. Again, thank you! :)
Keep in mind that for production you should probably specify the origins the allow through cors. In her example she opens it up to any source which is also a small vulnerability. You can also serve the react app from the backend and leave cors blocked. That way only your front end can call you apis and not a clone site.
@@lucasdesouza3658 Thank you so much! I just stumbled across that concept yesterday! This whole CORS thing has been so confusing. If you know of any kind of developer's security building checklist resources, it would be very much appreciated :)
This video is mandatory viewing for anyone making a frontend web app that connects to an API or backend of any sort. Remember guys: the best way to store secrets and credentials in your frontend is to NEVER EVER store secrets and credentials in your frontend.
Very nice, you created a proxy. I know that is just an example, but I prefer to separate the proxy code in another project. Then add security rules that your API can only be called from your domain, and other measures to avoid denial of service attacks.
I was looking for another video of yours and so happen to stumble upon this one and was like maybe I'll watch for a second. But I'm so glad I stumbled on this today! I will finish bootcamp next week and start a real job in a few weeks yet none of the instructors mentioned anything about how you can find the API key in the inspector tool! LOL Glad I know now!
One question - How to deploy this setup (frontend + backend) on hosting platforms like Netlify, Heroic, etc. for a working demo? Am I missing anything?
@@zmarc-I just figured this out. I was deploying the whole thing on netlify and expecting it to work but I just had to load the backend and frontend seperatly.
Really good tutorial, however I find missleading to say that this will prevent someone from using the paid API and use your money. This will only secure your API key, but if someone calls you API thousands of times you will still have the same problem, even if you didn't compromise you API key. If you really have a paid service behind an API I would strongly recommend to limit its use with throtling and user authentication, unless you are willing to take the risk of getting unusual traffic. Really good tutorial :)
CORS prevents people from being scammed when they’re using a browser. However it doesn’t prevent someone malicious from calling your API outside of the browser. Overall it’s a good tutorial but it should mention there is more needed to be completely secure.
so my main issue is that i want to deploy this to github pages and use fire base for authentification. if we store this inside of .env variables, don't we then have to push the .env file to github? and how is that secure? is storing it in the back end really allowing web users to not be able to read those variables?
This is the best explanation so far, even tough i use VueJS, but the code so far is still the same and can be used in VueJS. Thank you so much, keep going like this, okay?! 💪😎
I've a question. Someone can still inspect and see request URL (back-end endpoint). Even though API calling process happens on the backend, any one can use that endpoint to make request and get the response back. Yeah, they will not able to get API key, But they can make requests using our backend endpoint. Isn't it? How to solve that?
Great question! And you are right, this can still happen. For this you need a few extra steps including request limiting and auth- this video is just how to hide your api key. :) I can make a video on this if you would like
If you’re using NextJS you can use NextJS’ built-in API routes as a proxy to call your actual backend from and hide your backend’s URL and credentials in server-side environment variables (NOT prefixed with NEXT_PUBLIC_ in other words). Or if you are only getting info from an external API just use Next’s API routes, which are same-origin by default and can only be accessed by your frontend. This is actually a very good use case for NextJS as a framework.
So if I had to deploy the app, is the backend automatically deployed with production build? or does it have deployed separately? If so can you demonstrate how to properly deploy your frontend and backend to correspond properly.
Never use front-end for sensitive data calls, always let the back-end handle those in a secure way. So learn some back-end and all will be good in your apps.
@10:23 where you configure the configuration for your run commands, how do i configure that in vscode? I've tried researching, but I can't figure out how to get the edit configuration screen to pop up like yours and edit the run command? Thank you for the tutorial!
Hello! I am using Webstorm for this so it’s different than vscode :). But you can just edit the npm run command in the package.json file also, and run the command in the terminal. Does that make sense ?
@@aniakubow Ahh thank you for the quick response, i really appreciate it. Yeah, I ran npm start:front end and it seemed to work. Took me a bit of configuring, but my imdb api is looking real nice. Thanks again!
Thanks for the video, but i still don't get it. The api key maybe secure now but... What is stopping someone from making requests directly to your backend and using up all your quota for free. He does not even need an api key now, just the url of your backend. What can we do for this?
@@amolsingh5882 why stop the others and not your own frontend then? Did the video include some way to whitelist only your own app? If i understood correctly it even included a cors plugin in the backend to allow such requests.
Ideally you wouldn't even store any sensitive keys in your repo, especially in a commercial codebase with several/many engineers working on it. Depending on what infrastructure you use to host your backend, a better solution would be to store any secret values securely (not in plain text) and pass these values through at runtime. For example if you were using serverless functions with Azure, you could store your secrets in Azure Key Vault and retrieve what's needed when the function is executed (same concept for other cloud providers). This way your secrets are encrypted and secured properly while not exposed within your repo, on your server or to any team members who don't need to view these values.
Thank you Ania ! But it can't be only deploy on github pages, netlify, ... and other client side host, isn' t it ? With this solution the code should be deploy on Heroku, AWS, or other server side host, isn't it ?
Great Video! Some call this pattern "Backend for Frontend" or BFF. It can be used to store authentication tokens in the backend instead of the browser cookies or local storage.
I’m so happy you found this useful! Yes , I really wanted to show why it’s not safe to store API keys on the frontend too :) thanks so much for your kind words and support
its working perfectly in local but i need to depolye in iis so i need to build the application on that case what should i do with index.js and so fetching url of backend nodeserver url ?
You can also paste it in your package.json to hide your source code from the Chrome Dev Tools : "scripts": { "build": "GENERATE_SOURCEMAP=false react-scripts build" }
How does this help? I mean what prevents someone from just calling that backend endpoint and using the token? Is there any authorization on the backend API?
Hi, I use Firebase for work and unfortunately those values that I "hide" in .env are visible in some operations in the browser console. I don't know if this is normal in Firebase?
Just found this video and ive already uploaded a movie app to my GitHub im new to web dev. Should i remove the app . She said someone can still find your API key in your github history how do i fix that can someone help me .
How to deploy this to the GitHub Pages? I did it and get frontend working, but I since deployed it to the GitHub, now I have ERR_CONNECTION_REFUSED error from localhost:8000 -webpage, and I can not get any convertions working. any help please?
This is why I wish web development would move away from putting so much application logic into a frontend app. Anything on the frontend is visible by the user. Any validation in your front end app just be replicated in your backend logic if you want it to remain secure. I miss minimal frontend apps.
Thank you for the video! One thing I don't understand though. Will it still work when we build the frontend project statically, deploy it on a VPS and also get the backend's index.js running on that VPS? When a user opens our published static frontend, will the localhost then will be relative to the user?
Hi Ania. Do you know how we can display the currency exchange rate with only 2 decimal points please? Right now it shows it with 6 decimal points. Thanks!
Thank you for this clear video. Very helpful. I wonder that after creating a small backend here, how do we prevent outsider usage. We hid the key but open the door completely. If they use our backend, instead of stealing our key, we may see the big fat bill anyway.
That is a great question! There are other steps to do this that I can make a video on, including request limiting and making sure the API is used only on your domain etc. Watch this space :)
@@aniakubow First of all, thank you so much for this great tutorial. That would be so nice if you could also make a vdeio.

It would be super sweet of you to make a tutorial on this. Many many thanks! :)
Thanks, I got confused on the whole parameter thing. My API call doesn't use queries so I had to pass my front-end parameter as the useState array and declare it in expressjs as const stateThing = req.query.stateThing
Hi thank you for this video it helped me A LOT, I'm just beginning to understand backend and API and I am wondering aren't malicious people can still make request and use the api key by inspecting the frontend code, find the url to the backend and then do many request to the server?

Wonderful question - there are other steps you can do to increase security like request limiting, making sure the API is only used with your domain - I can make a video about this too / not just hiding your API key :)
Thanks Ania! It is a very helpful tutorial! You saved my day! I was wondering how we can move the index.js file under an api forlder so we can deploy as serverless function (for use on vercel, netfly etc)
Thanks so much! You can move the file to an api folder - however, you might have to rewrite the code :) I have a tutorial on writing your own Netflix serverless function if you want to check that out 😊
@@aniakubow Thanks! I did! It is pretty understandable from beginners' perspective! Thans for sharing! About the last question, I did move it and it work but I need to make some code adjustments as you mentioned! Thanks again!
Hey, Ania 😀 Could you please tell us what if we have an API KEY protected backend? How can we use that secret in React ? It will be visible in a source code 🙃
I’d be careful as some services may not offer that. If you’ve ever exposed your API key assume it is not safe anymore and reissue it from whatever service your using.
Hello Ania. Thanks a lot for your time and this tutorial! I have a question about the deployment. How to deploy the backend without it being revealed? Thanks again
Create environment variables with the service you’re using to deploy your code. I’ve done this with Heroku, I’m sure it is possible with other services too.
use a reverse proxy to store API keys , and make actual API calls from there, Request structure: Client -----> Reverse Proxy --------> Backend React ------> API keys stored here -----> Backend that use API key Reverse proxy can also be used to remove some headers like X-powered-by , rate limiting , as a load balancer etc.
Reverse Proxy to store api keys? That doesnt really make sense. You would store the key in the backend itselft or any store management, etc. You can use a revese proxy to centralize your authentification and authorization concept.
I'm confused as to where my messages are gone? I gave a few pieces of advice as to how to pass environment variables. Could you check your spam box out?
@ 14:09 you were prompted between Arabic / English translation. are you learning Arabic these days? I wouldn't be surprised if you were :) BTW great value lessons you offer indeed
Doesn't app.listen() accept the PORT constant, or why do you put it as number 8000 if it is already defined as constant :P
