GitHub Pages
Note: this feature is available with
[email protected]
and higher.
Step 1: Add homepage
to package.json
The step below is important!
If you skip it, your app will not deploy correctly.
Open your package.json
and add a homepage
field:
"homepage": "https://gfrodriguezclon.github.io/gfrodriguezclon/",
Create React App uses the homepage
field to determine the root URL in the built HTML file.
Step 2: Install gh-pages
and add deploy
to scripts
in package.json
Now, whenever you run npm run build
, you will see a cheat sheet with instructions on how to deploy to GitHub Pages.
To publish it at https://myusername.github.io/my-app, run:
npm install --save-dev gh-pages
Add the following scripts in your package.json
:
// ...
"scripts": {
// ...
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
}
The predeploy
script will run automatically before deploy
is run.
Step 3: Deploy the site by running npm run deploy
Then run:
npm run deploy
Step 4: Ensure your project’s settings use gh-pages
Finally, make sure GitHub Pages option in your GitHub project settings is set to use the gh-pages
branch:
Step 5: Optionally, configure the domain
You can configure a custom domain with GitHub Pages by adding a CNAME
file to the public/
folder.
Notes on client-side routing
GitHub Pages doesn’t support routers that use the HTML5 pushState
history API under the hood (for example, React Router using browserHistory
). This is because when there is a fresh page load for a url like http://user.github.io/todomvc/todos/42
, where /todos/42
is a frontend route, the GitHub Pages server returns 404 because it knows nothing of /todos/42
. If you want to add a router to a project hosted on GitHub Pages, here are a couple of solutions:
- You could switch from using HTML5 history API to routing with hashes. If you use React Router, you can switch to
hashHistory
for this effect, but the URL will be longer and more verbose (for example,http://user.github.io/todomvc/#/todos/42?_k=yknaj
). Read more about different history implementations in React Router. - Alternatively, you can use a trick to teach GitHub Pages to handle 404 by redirecting to your
index.html
page with a special redirect parameter. You would need to add a404.html
file with the redirection code to thebuild
folder before deploying your project, and you’ll need to add code handling the redirect parameter toindex.html
. You can find a detailed explanation of this technique in this guide.
