GitHub Pages Deploy Action :rocket:

This GitHub Action will deploy your project to GitHub Pages. It can be configured to upload your production-ready code into any branch you'd like, including gh-pages and docs.

Getting Started :airplane:

You can include the action in your workflow to trigger on any event that GitHub actions supports. If the remote branch that you wish to deploy to doesn't already exist the action will create it for you. Your workflow will also need to include the actions/checkout step before this workflow runs in order for the deployment to work.

You can view an example of this below.

``yml
name: Build and Deploy
on: [push]
jobs:
build-and-deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout 🛎️
uses: actions/checkout@v2 # If you're using actions/checkout@v2 you must set persist-credentials to false in most cases for the deployment to work correctly.
with:
persist-credentials: false

- name: Install and Build 🔧 # This example project is built using npm and outputs the result to the 'build' folder. Replace with the commands required to build your project, or remove this step entirely if your site is pre-built.
run: |
npm install
npm run build

- name: Deploy 🚀
uses: JamesIves/github-pages-deploy-action@releases/v3
with:
ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
BRANCH: gh-pages # The branch the action should deploy to.
FOLDER: build # The folder the action should deploy.
`

If you'd like to make it so the workflow only triggers on push events to specific branches then you can modify the on section.

`yml
on:
push:
branches:
- master
`

#### Install as a Node Module 📦

If you'd like to use the functionality provided by this action in your own action you can install it using yarn by running the following command.

`
yarn add github-pages-deploy-action
`

It can then be imported into your project like so.

`javascript
import run, {
init,
deploy,
generateBranch,
ActionInterface
} from "github-pages-deploy-action";
`

Calling the functions directly will require you to pass in an object containing the variables found in the configuration section, you'll also need to provide a workspace with a path to your project.

`javascript
import run from "github-pages-deploy-action";

run({
accessToken: process.env["ACCESS_TOKEN"],
branch: "gh-pages",
folder: "build",
repositoryName: "JamesIves/github-pages-deploy-action",
workspace: "src/project/location",
});
`

For more information regarding the action interface please click here. You can find the npm listing for the module here.

Configuration 📁

The with portion of the workflow must be configured before the action will work. You can add these in the with section found in the examples above. Any secrets must be referenced using the bracket syntax and stored in the GitHub repository's Settings/Secrets menu. You can learn more about setting environment variables with GitHub actions here.

#### Required Setup

One of the following deployment options must be configured.

| Key | Value Information | Type | Required |
| -------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------- | -------- |
| GITHUB_TOKEN | In order for GitHub to trigger the rebuild of your page you must provide the action with the repository's provided GitHub token. This can be referenced in the workflow yml file by using ${{ secrets.GITHUB_TOKEN }}. If you experience any issues with your changes not being reflected after the deployment it may be neccersary to use either the SSH or ACCESS_TOKEN options. | secrets / with | Yes |
| SSH | You can configure the action to deploy using SSH by setting this option to true. For more information on how to add your ssh key pair please refer to the Using a Deploy Key section of this README. | with | Yes |
| ACCESS_TOKEN | Depending on the repository's permissions you may need to provide the action with a GitHub personal access token instead of the provided GitHub token in order to deploy. You can learn more about how to generate one here. This should be stored as a secret. | secrets / with | Yes |

In addition to the deployment options you must also configure the following.

| Key | Value Information | Type | Required |
| -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------ | -------- |
| BRANCH | This is the branch you wish to deploy to, for example gh-pages or docs. | with | Yes |
| FOLDER | The folder in your repository that you want to deploy. If your build script compiles into a directory named build you'd put it here. Folder paths cannot have a leading / or ./. If you wish to deploy the root directory you can place a . here. | with | Yes |

#### Optional Choices

| Key | Value Information | Type | Required |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------ | -------- |
| GIT_CONFIG_NAME | Allows you to customize the name that is attached to the git config which is used when pushing the deployment commits. If this is not included it will use the name in the GitHub context, followed by the name of the action. | with | No |
| GIT_CONFIG_EMAIL | Allows you to customize the email that is attached to the git config which is used when pushing the deployment commits. If this is not included it will use the email in the GitHub context, followed by a generic noreply GitHub email. | with | No |
| REPOSITORY_NAME | Allows you to specify a different repository path so long as you have permissions to push to it. This should be formatted like so: JamesIves/github-pages-deploy-action. | with | No |
| TARGET_FOLDER | If you'd like to push the contents of the deployment folder into a specific directory on the deployment branch you can specify it here. | with | No |
| BASE_BRANCH | The base branch of your repository which you'd like to checkout prior to deploying. This defaults to the current commit SHA that triggered the build followed by master if it doesn't exist. This is useful for making deployments from another branch, and also may be necessary when using a scheduled job. | with | No |
| COMMIT_MESSAGE | If you need to customize the commit message for an integration you can do so. | with | No |
| CLEAN | If your project generates hashed files on build you can use this option to automatically delete them from the deployment branch with each deploy. This option can be toggled on by setting it to true. | with | No |
| CLEAN_EXCLUDE | If you need to use CLEAN but you'd like to preserve certain files or folders you can use this option. This should be formatted as an array but stored as a string. For example: '["filename.js", "folder"]' | with | No |
| SINGLE_COMMIT | This option can be toggled to true if you'd prefer to have a single commit on the deployment branch instead of maintaining the full history. Using this option will also cause any existing history to be wiped from the deployment branch. | with | No |
| WORKSPACE | This should point to where your project lives on the virtual machine. The GitHub Actions environment will set this for you. It is only neccersary to set this variable if you're using the node module. | with | No |

With the action correctly configured you should see the workflow trigger the deployment under the configured conditions.

#### Deployment Status

The action will export an environment variable called DEPLOYMENT_STATUS that you can use in your workflow to determine if the deployment was successful or not. You can find an explanation of each status type below.

| Status | Description |
| ------------- |-------------|
| success | The success status indicates that the action was able to successfully deploy the project to the branch. |
| failed | The failed status indicates that the action encountered an error while trying to deploy the project. |
| skipped | The skipped status indicates that the action exited early as there was nothing new to deploy. |

If you'd prefer to use an SSH deploy key as opposed to a token you must first generate a new SSH key by running the following terminal command, replacing the email with one connected to your GitHub account.

`bash
ssh-keygen -t rsa -b 4096 -C "youremailhere@example.com" -N ""
`

Once you've generated the key pair you must add the contents of the public key within your repository's deploy keys menu. You can find this option by going to Settings > Deploy Keys, you can name the public key whatever you want, but you do need to give it write access. Afterwards add the contents of the private key to the Settings > Secrets menu as DEPLOY_KEY.

With this configured you must add the ssh-agent step to your workflow and set SSH to true within the deploy action. There are several SSH actions available on the GitHub marketplace for you to choose from.

`yml
- name: Install SSH Client 🔑
uses: webfactory/ssh-agent@v0.2.0
with:
ssh-private-key: ${{ secrets.DEPLOY_KEY }}

- name: Deploy 🚀
uses: JamesIves/github-pages-deploy-action@releases/v3
with:
SSH: true
BRANCH: gh-pages
FOLDER: site
`

This action is primarily developed using Ubuntu. In your workflow job configuration it's recommended to set the runs-on property to ubuntu-latest.

`yml
jobs:
build-and-deploy:
runs-on: ubuntu-latest
`

If you're using an operating system such as Windows you can workaround this using artifacts. In your workflow configuration you can utilize the actions/upload-artifact and actions/download-artifact actions to move your project built on a Windows job to a secondary job that will handle the deployment.

If you use a container in your workflow you may need to run an additional step to install rsync as this action depends on it. You can view an example of this below.

`yml
- name: Install rsync 📚
run: |
apt-get update && apt-get install -y rsync

- name: Deploy 🚀
uses: JamesIves/github-pages-deploy-action@releases/v3
`

If you're using a custom domain and require a CNAME file, or if you require the use of a .nojekyll file, you can safely commit these files directly into deployment branch without them being overridden after each deployment.

By default the git commands are hidden from the logs. If you'd like to turn them on you can set the ACTIONS_STEP_DEBUG` environment variable to true within the Settings/Secrets menu. If you're using this action in your own project as a node module via yarn or npm you may expose your secrets if you toggle this on in a production environment.
