Did you build React app and want to deploy it, following these simple steps you able to deploy and showing the world your amazing app.
I will show how to create and deploy React App using create-react-app and GitHub Pages
Prerequisites :
GitHub Account.
Install Git in your machine and Set up Git.
Make sure you have Node.js and Npm installed in your machine.
Notice You’ll need to have Node 8.10.0 or later on your local machine.
Procedure :
1- First create a repository named my-app using create-react-app.
npm init react-app my-app
2- We need to install GitHub Pages package as a dev-dependency.
cd my-app
npm install gh-pages --save-dev
3- Add properties to package.json file.
The first property we need to add at the top level homepage second we will define this as a string and the value will be "http://{username}.github.io/{repo-name}" {username} is your GitHub username, and {repo-name} is the name of the GitHub repository you created it will look like this :
"homepage": "http://yuribenjamin.github.io/my-app"
Second in the existing scripts property we to need to add predeploy and deploy.
"scripts": {
//...
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
}
4- Create a Github repository and initialize it and add it as a remote in your local git repository.
Now, create a remote GitHub repository with your app name and go back initialize this
git init
add it as remote
git remote add origin git@github.com:Yuribenjamin/my-app.git
5- Now deploy it to GitHub Pages.
just run the following command :
npm run deploy
this command will create a branch named gh-pages this branch host your app, and homepage property you created in package.json file hold your link for a live preview, or you can open the branch setting scroll down to GitHub Pages section you will find this:
6- commit and push your commit to GitHub. Optionally
git add .
git commit -m "Your awesome message"
git push origin master
Recap
We created React App using create-react-app
then we installed gh-pages as a dev-dependency
and in package.json file we added some properties homepage also in existing scripts property we added predeploy and deploy
and created a remote repository and initialize it
and run npm run deploy to generate a production build and deploy it to GitHub Pages.
if you have any questions, please don't hesitate to ask.
Always happy to hear from you

Hi! Thanks for the tutorial!
I accidentally copy pasted this on my terminal : git remote add origin git@github.com:Yuribenjamin/my-app.git
and now i keep getting this:

git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights

I tried git remote rm origin and it still won't work. can you please advice me on what i should do here? I will really appreciate it!
No problem
git remote - vWill display origin and the wrong remote url
To delete it
git remote rm originThen check again
git remote - vWill display nothing time to add the right one
Happy Hacking
Hi Ibrahim, Thanks for the fast reply!
I did this:
Trishas-MBP-2:src TrishaBernice$ git remote rm origin
Trishas-MBP-2:src TrishaBernice$ git remote -v
Trishas-MBP-2:src TrishaBernice$ git remote add origin git@github.com:trishabernice/portfolio.git
Trishas-MBP-2:src TrishaBernice$ npm run deploy
and I still got this...

Is there anything else I can try to fix the issue?
Use http or ssh
Earlier I did this:
Trishas-MBP-2:src TrishaBernice$ git remote add origin github.com/trishabernice/portfolio...
and i did git remote rm origin and then added the one for ssh and I still got the same error.
Do you have any suggestions for what I can do? I'll really appreciate it!
or
mejimaru's solution worked if anyone ran into the error that @trishabernicer faced.
Thanks @mejimaru
In response to @trishabernice 's problem with
node_modules/.cache/gh-pages, a fix with this for me was to simply remove/deletenode_modules/.cache/gh-pages, then executenpm run deployonce more.This issue I'm referring to (and its answer) can be found on StackOverflow here: stackoverflow.com/questions/639645...
I'd the same problem and then read a lot of blogs/articles I find the solution. I'd changed the git in my
PATHin this question you can find the solution then open the a new terminal and run the commandnpm run deployI hope this help you.Regards.
Very interesting tutorial Ibrahim!
I have a question: how do you update the production build?
I mean: after deploying the app on GitHub, I realized that I need to change some stuffs. So I have generated new commits. If my app points to the master branch, how can I reflect that new changes on the production build then?
Thanks
Make changes commit then deploy again, that's it
Ok! Thanks!
If you want to updating the release check
create-react-app.dev/docs/updating...
Perfect!
Thanks!
so i commit and push to my origin/github master, then i run "npm run deploy" again?
yes
just write a command like below -
npm run deploy
Hello ! This was a big help ! However, at step 5, I received this error:

Forgive me but how do I do that ? I am a newbie here
Check this help.github.com/en/enterprise/2.15...
Hey I'm getting the same error. Did you resolve it?
found this post useful, thank you...I have a question, after i have pushed my react app to github page, when i visit the url it displays blank with no error message shown, any pointers why i'm seeing this happen/
plus this is my first project in react.
Thank you
I got this same problem in the beginning. If you follow this tutorial correctly,then try this one.
Your home page route should be like this
instead forand in your rendered component change the instead for And another important point you should consider. your github repo name must be valid name for example dots or space should not be in your repo name because that things conflict with URL.
Thanks a lot @Piruthuvi.
this should be mentioned in the create-react-app docs, was so frustrated because of this simple code change, thanks alot mate @Piruthuvi
Thanks, double check your process, if the same error occurred please share with me your github repo and I will help immediately
Hello, Ibrahim.
I have such problem:
fatal: A branch named 'gh-pages' already exists.
npm ERR! code ELIFECYCLE
npm ERR! errno 1

Can you help me? Here is my repo github.com/pitysek16/Movies-React-app
hii katerina check last commit in this repo
github.com/Yuribenjamin/Movies-Rea...
and already your app running
yuribenjamin.github.io/Movies-Reac...
if you fix this tell me to delete repo above.
Thank you! It is work
Please how where you able to fix that, I'm having same issue here
hi sir, i am experiencing the same error. can you please show me how to fix it?
thank you in advance
Please what did you do to resolve it. I'm having the same issue.
when you receive error " A branch named 'gh-pages' already exists.", you have to delete the .config sub-folder in gh-pages folder in node_module.
Hey Ibrahim, my app won't deploy. I went over your instruction twice but am still having issues. Would you mind taking a look at my repo, it's github.com/ZacASTaylor/zacastaylor.... Thanks!
Hello Zac
you did well but you need to make some changes to make your project run online kindly follow this process carefully:
1 - you need to change repo name because of dots in repo name conflict with URL, zacastaylor it's good enough and works with me.
2- in package.json change homepage with new value should be "zacastaylor.github.io/zacastaylor"
2.1- change predeploy to the new value "npm run build", yarn is fine but it's not tested.
3- in App.js change line 25 to be <Route exact path='/zacastaylor'
4- in component => layout => Header.js line 37 to be <Link to="/zacastaylor"
download the project and change the repo name, after that remove the old connection you can check
git remote -vyou will see this connected with old repo remove connection bygit remote rmthis command will take one parameter the full command will begit remote rm origin.if you check again
git remote -vwill display nothing to your terminal after that do the change above and make a commit with new changes then push and runnpm run deploy.happy to hear from you Zac, kindly update me if this process success or fail
Thanks so much for you help Ibrahim, but the issue was that I needed slightly different instructions because I am trying to have my React app hosted on my GitHub user page and not a project page. I followed the instructions here: dev.to/javascripterika/deploy-a-re...
Thanks again!
video is private...
How would I add changes (such as changing the header, font, color, etc) to the page after deploying? I committed and pushed and it successfully shows on my github repo but when I go to my live link none of my changes show.
My repo: github.com/kimberlybone/my-portfol...
My live site: kimberlybone.github.io/my-portfoli...
did you try to delete GH-page branch && build directory, and deploying the app again? if not try this
Hey - does this mean, everytime you update something on the page, we need to Delete Gh-page branch && delete build directory folder, and basically deploy again?
Is there no automatic update happening? (i.e. like, when deployed on netlify or smhtg.) ? Thanks!
to update run
npm run deployafter each updateas you said committing and deploying works fine but you have to wait for the change to take an effect on the live link ( and sometimes the repo itself)
Hi. I am having issues deploying my React app to github pages. Could you take a look?
github.com/LKian/ToDoList
I added homepage to package.json, along with
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
I added the gh-pages as a dev dependency
The error seems to occur when I run "npm run deploy"
todolist@0.1.0 build /mnt/c/Users/Admin/Desktop/Code/todolist

hello Leah
give it try again I cloned your repo and walked through my tutorial,
and everything working fine with me check ...
dev-to-uploads.s3.amazonaws.com/i/...
dev-to-uploads.s3.amazonaws.com/i/...
dev-to-uploads.s3.amazonaws.com/i/...
Oh thanks for the screenshots. The only difference I noticed was that for some reason even though I installed "gh-pages" yesterday, it wasn't there. I re-installed and gh-pages now appears in package.json.
I then tried to npm run deploy and am still getting an error. Any other thoughts as to what is wrong?
Creating an optimized production build...
Failed to compile.
./src/index.js
Error: [BABEL] /mnt/c/Users/Admin/Desktop/Code/todolist/src/index.js: Cannot find module '@babel/core' (While processing: "/mnt/c/Users/Admin/Desktop/Code/todolist/node_modules/babel-preset-react-app/index.js")
I read that the gh-pages is supposed to create a new branch but that is not happening. I'm going to try to delete the repo and start from scratch. After I make a new repo, should I still be running the following setup commands?
git init
git add README.md
git commit -m "first commit"
git remote add origin git@github.com:LKian/ToDoList.git
git push -u origin master
and THEN running npm run deploy? Still getting an error
Update: I deleted node_modules and package-lock.json and npm installed again. And it says published!!!!!!!!!! Still not showing up on the live page but I know sometimes it takes a while. Will keep you updated :-)
lkian.github.io/ToDoList/index.html
Got it. Apparently you have to add "/index.html" to the path
no, just the URL that equal to the home page key in the package.json
lkian.github.io/ToDoList
dev-to-uploads.s3.amazonaws.com/i/...
Hello Ibrahim, thanks for the tutorial.. a question.. I pushed my commit to a master branch before pushing to a remote.. How do I get on further? Do I have to do git checkout -b gh-pages? please let me know. Thanks in advance.. warm regards :)
Just
git pushthanks but when ? I created a main page before a gh-pages what do I do? Do I create a gh-page on command line? sorry if it is a stupid question
I don't get it!
But delete all branches remote and local
You now has a master branch commit your work and deploy it again
Sorry forget about it
Great article. I got it to work publishing the react app. Note that for the homepage I used "https" rather than "http". Also since I used yarn for my packages I tried to use it for the deploy as well, but it didn't work. I got it to work with npm however. Thanks again.

Very nice post Ibrahim. Really helped me.
I was able to deploy my page to gh pages. The only thing is that my background image is not loading.
I have the image in my src folder. While running the app on my local server, The site was displaying my image perfectly. While i deploy on gh pages, image disappears.
I have tried adding the image using jsx, but to no avail. Previously i imported the image to my scss. Thought that was the problem.
Can someone tell me what's going on?
app is deployed here- jaykeeshow.github.io/simple-app/
Thanks buddy, I see your image doesn't load i saw the build file in yout code, try to build and run build locally before you deployed it and check why the image didn't appear
dear ibrahim, i dont know how to run build locally. when i run- npm install -g serve,
I get an error.

Hello, i am doing the routing for my website, but only the landing page shows up. Could you have a look? I think the problem should be in index.js, main.js, App.js. Thanks!!

github.com/tianyiz8/personal-website
Hey thanks for your comment, handling route in react can easly done by using react router package, not by default way as i saw in your app, also read about Single Page App, and declaritive programming
github.com/ReactTraining/react-router
Happy Hacking!
Hello! Could you be more specific? I did use react-router-dom, and where are declaritive programming and Single Page App? I still have no idea how to make it work.
Thanks!
if so then why you declare a tag to route
check
reacttraining.com/react-router/web...
Lovely. Thank you for this.
If you're having the following error:
Host key verification failed.
fatal: Could not read from remote repository.
Remove your remote:
git remote remove origin
Then create a new remote. no marks:
git remote add ht tps://github.com/username/repo-name.git
Using the git@github.com:... syntax ends up using SSH to clone, and inside the container, your private key is not available.
Created this account just for thanking you, mine says invalid url all the time. Tried changing the homepage, reinstalling the package, removing the ssh remote, and even switching the node version lol. Thanks, your solution works.
Hello Ibrahim. I followed your tutorial and I am trying to deploy my first app to github pages. I keep getting this error when I run "npm run deploy".
gh-pages -d build
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Any help please?
make sure that you provide the right credentials

Really important tutorial. Thank you!
There's an error when I try to install react-bootstrap to my app.
any suggestions on that?
Im very new to react.
I deployed my react app to GitHub and its working but not what I expected. When I run the app on the localhost its works perfectly and I can see all the pictures and all the navigation works. After deploy on Github, I can not see anymore the images which were a relative path link to my app and also navigation back button seems not working. Any hints on how to overcome these issues. Here is react app Github deployed Link- Your site is published at mjachowdhury.github.io/mjacportfolio/
would you please look into this
hey mjach your problem-specifically in routing there's a difference between routing on dev server and the production double-check this point I know you can do it, and if not sadly contact me and I will fix this for you
Helloooo :)
So, I am begginer... and I did what you "said"...and it worked... although I have two issues that I dont understand.
first issue check routing, second cuz you watch gh-branch change to master
happy hacking!
Thanks a lot! On my way to check the stuff!!!
Keep safe from Covid!
Hi Ibrahim, I have recently built my first react project. Despite having followed all your instructions on the thread, my app won't deploy. Would appreciate it if you could take a look at it for me:
ian1202.github.io/react-project/
Thank you!
Not all the instruction I think, do this changes to package dot json, change home to homepage and add the right value "http://{username}.github.io/{repo-name}" . Solved
It worked! Sorry for having missed that detail. Thank you!
Your are welcome, Alawys happy to help 🙂
Hi, I have this error:
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
can you provide your github repo
Sure: github.com/andrii1
I'm trying github pages here: github.com/andrii1/andrii1.github.io
in this tutorial, I introduced deploying react App to Github pages, I see your app didn't consume react packages, so you can deploy your app using the normal process by open settings navigate to GitHub Pages then in Source choose the master branch if you want run your app from the master branch.
happy hacking!
Sorry, can you specify a bit? I need to push it in separate repository inside /andrii1.github.io?
what I need to say your app not a react app so you don't need this tutorial to deploy it to gihtub you can deploy it from the setting
So, I have my React app in separate folder my-app, when I'm trying to upload it to GitHub, I see this:
dev-to-uploads.s3.amazonaws.com/i/...
Update: issue was solved with:
git push -f origin master
But, still andrii1.github.io/my-app is not live..
github.com/andrii1/my-app
Hello Ibrahim, my app deploys now, but it is showing only HTML plain webpage. Would you mind looking at my Github repo, and guide me any necessary changes to my project? github.com/eaindra-wp/portfolio
hey Eaindra can you make master is the default, not Github pages to be able to clone your repo.
and put "homepage": "xyz....", at the top of your module
and check console errors, make sure console is free!
Hello Ibrahim, I have updated the steps that you suggested, but it seems like my react-app cannot find the CSS files yet.
Hello, Ibrahim! Thank you for your tutorial. I was just wondering what changes would be necessary if I wanted to deploy the react app directly to the homepage (eg.: username.github.io), if that's even possible.
Hey Marissa, yea check this dev.to/javascripterika/deploy-a-re...
Happy hacking!
In case anyone else runs into the same issue that I had. When running the build command for the first time, I got error:
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Creating a new branch
gh-pagesmanually before running the deploy fixed this.hey, Ibrahim I don't know where I am going wrong can you please check where is the issue
github.com/Bhargav252000/fakegram
the error I am getting
Hi Ibrahim, First Thank you for a such a wonderful and helping blog.I have one doubt that i was able to succesfully deploy my react app but when i make changes locally i am unable to get those changes on my react app. Can you please guide how to do that in a proper way?
Yeah make changes commit and run the deploy again to generate fresh build your terminal will tell you the rest,
Another way delete build delete gh branch make changes rub deploy
Happy Hacking
I followed the instructions and got the same messages from the terminal up to right under the "gh-pages -d build" and then I get these lines
my repo is github.com/Kriviears/React-Portfolio
hey Kriviears, first you should fix all bugs before deploy, second check this repo this is your app running successfully, and double-check the fix commit after you fix this problem notify me to delete you repo = >

First of all thank you for your time and kind help to all us junior developers here. Much appreciated!!!! I'm having the same issue as others here. I get this far:
Search for the keywords to learn more about each warning.
To ignore, add // eslint-disable-next-line to the line before.
File sizes after gzip:
81.32 KB build\static\js\main.92314488.js
65 B build\static\css\main.d41d8cd9.css
The project was built assuming it is hosted at /jonchristieportfolio/.
You can control this with the homepage field in your package.json.
The build folder is ready to be deployed.
To publish it at mathcodes.github.io/jonchristiepor..., run:
npm run deploy
Published
BUT it still doesn't work. I tried using different combinations of branches and root/ vs doc/ in githb pages in settings, I tried pushing just the build folder. I've tried an embarassing amount of things to where I need your help!
Should I be in /root or docs/ for in github pages? What do I do after I get to the step above. It says its built and that I should run npm run deploy again... tried that no luck. What is the next step? Here is my repo. I hope you can drag me out of this vortex!!! Thank you in advance :)
github.com/mathcodes/jonchristiepo...
This doesn't work for me at all. I get a 404 Error.
Are you sure there isn't another step you are missing?
My package.json has this :
"name": "shape-shop-frontend",
"homepage": "oliverwatkins.github.io/alpenhof",
I have connected to my remote repository here :
github.com/oliverwatkins/shape-sho...
And then I have run
"npm run deploy"
Are you sure there you don't have to create some io repository? In the github pages it says something about creating an "io" repo :
.github.io
Hello everbody,
I fixed the 404: "I ran into this problem myself and finally discovered a simpler solution. The problem is that Jekyll ignores all files that start with _. The simple solution is to add a .nojekyll file to your docs dir."
Here's how:
git checkout gh-pages
mkdir docs/
touch docs/.nojekyll
git push origin gh-pages
And a redeploy:
npm run deploy
I have deployed my react app on GitHub pages thanks to you Ibrahim. And now I have added some changes in the app, and I have committed the changes, but now when I am deploying it (using npm run build ) it is giving me the error, PLease help.
