How to publish a website made by Node.js to Github Pages?

I made a website using Node.js as the server. As I know, the node.js file should start working by typing commands in terminal, so I'm not sure if Github Pages supports node.js-hosting. So what should I do?

GitHub pages host only static HTML pages. No server side technology is supported, so Node.js applications won't run on GitHub pages. There are lots of hosting providers, as listed on the Node.js wiki.

App fog seems to be the most economical as it provides free hosting for projects with 2GB of RAM (which is pretty good if you ask me).
As stated here, AppFog removed their free plan for new users.

If you want to host static pages on GitHub, then read this guide. If you plan on using Jekyll, then this guide will be very helpful.

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

I was able to set up github actions to automatically commit the results of a node build command (yarn build in my case but it should work with npm too) to the gh-pages branch whenever a new commit is pushed to master.

While not completely ideal as i'd like to avoid committing the built files, it seems like this is currently the only way to publish to github pages and should work for any frontend Node.js app (or app built with a frontend framework like React or Vue) that can be served as static files.

I based my workflow off of this guide for a different react library, and had to make the following changes to get it to work for me:

• updated the "setup node" step to use the version found here since the one from the sample i was basing it off of was throwing errors because it could not find the correct action.
• remove the line containing yarn export because that command does not exist and it doesn't seem to add anything helpful (you may also want to change the build line above it to suit your needs)
• I also added an env directive to the yarn build step so that I can include the SHA hash of the commit that generated the build inside my app, but this is optional

Here is my full github action:

name: github pages

on:
    push:
        branches:
        - master

jobs:
    deploy:
        runs-on: ubuntu-18.04
        steps:
        - uses: actions/checkout@v2

        - name: Setup Node
            uses: actions/setup-node@v2-beta
            with:
            node-version: '12'

        - name: Get yarn cache
            id: yarn-cache
            run: echo "::set-output name=dir::$(yarn cache dir)"

        - name: Cache dependencies
            uses: actions/cache@v2
            with:
            path: ${{ steps.yarn-cache.outputs.dir }}
            key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
            restore-keys: |
                ${{ runner.os }}-yarn-
        - run: yarn install --frozen-lockfile
        - run: yarn build
            env:
            REACT_APP_GIT_SHA: ${{ github.SHA }}

        - name: Deploy
            uses: peaceiris/actions-gh-pages@v3
            with:
            github_token: ${{ secrets.GITHUB_TOKEN }}
            publish_dir: ./build

Alternative solution

The docs for next.js also provides instructions for setting up with Vercel which appears to be a hosting service for node.js apps similar to github pages. I have not tried this though and so cannot speak to how well it works.

No, You cannot publish on Github pages. Try Heroku or something like that. You can only deploy static sites on github pages. You can't deploy a server on github pages.
