How to run the deploy only on main branch?

[simonppg]

Is there a way to only run the deploy on main branch? I have this configuration but it also runs when a new pull request is created, could somebody point me out to the right direction?

name: cd

on:
  push:
    branches:
      - main  # Set a branch name to trigger deployment
  pull_request:

jobs:
  cd:
    runs-on: ${{ matrix.os }}

    strategy:
      matrix:
        os: [ubuntu-latest]
        node: [14]

    steps:
      - name: Checkout
        uses: actions/checkout@master

      - name: Setup node env
        uses: actions/setup-node@v2.1.2
        with:
          node-version: ${{ matrix.node }}

      - name: Install dependencies
        run: npm install

      - name: Generate
        run: npm run generate

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

I don't know if this is relevant but I'm using nuxtjs static pages.

The latest README mentions this already.

name: GitHub Pages

on:
  push:
    branches:
      - main  # Set a branch name to trigger deployment
  pull_request:

jobs:
  deploy:
    runs-on: ubuntu-20.04
    concurrency:
      group: ${{ github.workflow }}-${{ github.ref }}
    steps:
      - uses: actions/checkout@v2
...
      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
+       if: ${{ github.ref == 'refs/heads/main' }}
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public

And, I recommend you to use npm ci which is faster and more stable than npm install.

npm-ci | npm Docs

This command is similar to npm install, except it's meant to be used in automated environments such as test platforms, continuous integration, and deployment -- or any situation where you want to make sure you're doing a clean install of your dependencies.

Thanks for the response, I made the change and it stop deploying on all branches even on main branch.

[peaceiris]

How about if: ${{ github.ref == 'refs/heads/main' }}?
