Set build commands per branch

Last reviewed: over 2 years ago

This guide will instruct you how to set build commands on specific branches. You will use the CF_PAGES_BRANCH environment variable to run a script on a specified branch as opposed to your Production branch. This guide assumes that you have a Cloudflare account and a Pages project.

Set up

Create a .sh file in your project directory. You can choose your file's name, but we recommend you name the file build.sh.

In the following script, you will use the CF_PAGES_BRANCH environment variable to check which branch is currently being built. Populate your .sh file with the following:

Terminal window
# !/bin/bash
if [ "$CF_PAGES_BRANCH" == "production" ]; then
# Run the "production" script in `package.json` on the "production" branch
# "production" should be replaced with the name of your Production branch
npm run production
elif [ "$CF_PAGES_BRANCH" == "staging" ]; then
# Run the "staging" script in `package.json` on the "staging" branch
# "staging" should be replaced with the name of your specific branch
npm run staging
else
# Else run the dev script
npm run dev
fi

Publish your changes

To put your changes into effect:

  1. Log in to the Cloudflare dashboard and select your account.
  2. In Account Home, select Workers & Pages > in Overview, select your Pages project.
  3. Go to Settings > Build & deployments > Build configurations > Edit configurations.
  4. Update the Build command field value to bash build.sh and select Save.

To test that your build is successful, deploy your project.
