## Overview

The CI flow consists of three key steps: **[Initialize Release](#step-1-initialize-release), [Create Release Artifacts](#step-2-create-release-artifacts), and [Publish Release](#step-3-publish-release)**. These workflows ensure a structured process for versioning, creating artifacts, and publishing new releases.

---

## Workflow Templates

Each workflow step has an associated **template** to set up workflow triggers and call the reusable workflows from the Shared CI.

### Template Purposes:

- Hook into repository workflow triggers.
- Call reusable workflows in the Shared CI.
- Standardize workflow execution across repositories.

---

## Shared CI

### Step 1: Initialize Release

- **Purpose**: Prepares a new release by incrementing the version and creating a release branch.
- **Triggers**: Manual dispatch with required parameters.
- **Actions**:
  1. Increment the version number.
  2. Create and checkout a new branch (`release/version`).
  3. Commit the updated version number.
  4. Update and commit the changelog.
  5. Open a draft GitHub release.
  6. Create a pull request for review. _Note, this new pull request will trigger the next step._
- **Required Parameters**:
  - `branch` (target branch for the release)
  - `release_type` (e.g., major, minor, patch)
- [Initialize Release Template](https://github.com/rokucommunity/.github/blob/master/workflow-templates/initialize-release.yml)

### Step 2: Create Release Artifacts

- **Purpose**: Creates the release artifacts, and upload them.
- **Triggers**: Pushes and updates to `release/*` branches.
- **Actions**:
    1. Build the release artifacts.
    2. Upload artifacts to the draft GitHub release.
- **Required Parameters** _(these are hardcoded in the template)_:
  - `branch` (The head ref for the release PR)
  - `node-version` (The node version used to build the artifacts)
  - `asset-paths` (The glob path used to get all the release artifacts)
- [Create Release Artifacts Release Template](https://github.com/rokucommunity/.github/blob/master/workflow-templates/create-release-artifacts.yml)
### Step 3: Publish Release


- **Purpose**: Finalizes the release by marking it as non-draft and publishing the code.
- **Triggers**: Merging of a `release/*` branch.
- **Actions**:
  1. Mark the GitHub release as non-draft.
  2. Publish the release to users (e.g., npm, VS Code Marketplace).
- [Publish Release Template](https://github.com/rokucommunity/.github/blob/master/workflow-templates/publish-release.yml)
- **Required Parameters** _(these are hardcoded in the template)_:
  - `branch` (The head ref for the release PR)
  - `release-store` (The head ref for the release PR)

## Repository Setup

To integrate this release workflow system into a new repository, follow these steps:

1. **Add Workflow Templates**: Each repository must include the workflow templates: `initialize-release`, `create-release-artifacts`, `publish-release` from this repository. More details in this section: [Setting Up Template Workflows in a Repository](#setting-up-template-workflows-in-a-repository)

     [_Example repository workflow setup_](https://github.com/rokucommunity/release-testing/tree/master/.github/workflows)

2. **Ensure Required NPM Script Exist**:
   - `package`: Compiles the application.

   _Example `package.json`_
   ```json
    "scripts": {
      "package": "echo \"Place holder for build command\" && mkdir out && echo \"Hello World!\" > hello.txt"
    },
   ```
3. **Build Artifacts Paths**:
   - The `package` script name and place all artifacts in a way that the `asset_paths` set in [Create Release Artifacts Release Template](https://github.com/rokucommunity/.github/blob/master/workflow-templates/create-release-artifacts.yml) is selectable.
   - The post-build step will look for release artifacts in this directory to upload to the GitHub release.

### Setting Up Template Workflows in a Repository  

To integrate the release workflow system into a repository, follow these steps to add the required workflow templates from the **RokuCommunity** organization:  

### Step 1: Add Workflow Templates  
1. Navigate to your repository on GitHub.  
2. Click on the **Actions** tab.  
3. Click **New workflow** or go directly to `.github/workflows`.  
4. Under **"Choose a workflow"**, find the **By RokuCommunity** templates:  
   - **Initialize Release**  
   - **Create Release Artifacts**  
   - **Publish Release**  
5. Click on each template and select **"Configure"**.  

### Step 2: Check needed edits
1. Edit `asset_paths` if needed
2. Edit `node-version` if needed
2. Edit `publish-store` if needed

### Step 3: Commit the Workflow Files
1. Click **Commit changes...**.  
2. Ensure the commit is made to the default branch (master)
5. Click **Commit changes**

Once these workflows are set up, your repository will automatically follow the structured release process!

## Recovering from a Failed Release CI

If the release CI fails and does not recover automatically, follow these steps to reset the release process:

1. **Delete the GitHub Release**
   - Go to the **Releases** section of your repository.
   - Find the failed release.
   - Click **Delete release**.

2. **Delete the Pull Request for the Release**
   - Navigate to the **Pull Requests** tab.
   - Locate the pull request associated with the release.
   - Close and delete the pull request.

3. **Delete the Release Branch**
   - Go to the **Branches** section of your repository.
   - Find the branch created for the release (e.g., `release/version`).
   - Delete the branch.

_Note there is a [workflow template: Delete Release](https://github.com/rokucommunity/.github/blob/master/workflow-templates/delete-release.yml) that does all three steps_

## Command Line

How would the command line work in each repository? The repos won't have the Reusable CI scripts.
