GitHub Action
Node App Helper Actions
This action is designed to help easily proxy any Node.js scripts into GH Actions to create workflows easily. By design, there are only a few predefined paths in this action, but the run
path is flexible enough to build any workflow you may design.
The entrypoint.sh
script takes in arguments to define what path to follow. There are currently two primary predefined tasks.
Each task is essentially a sub-task to the main entrypoint and will execute a very specific operation.
The primary task is run
. This simply executes the provided script within your NPM or yarn context. By configuring your action definition, you can use the run
task to chain any number of operations within your system.
For example, if you had an NPM script titled build
that would create your artifacts for deployment, you could set up your action like this:
action "Build" {
uses = "guahanweb/actions/node-app@master"
args = "run build"
}
NOTE: if you are using Yarn, provide an env
definition specifying the PKG_MANAGER
to be Yarn:
env = {
PKG_MANAGER = "yarn"
}
Under the covers, this is essentially going to run npm run build
or yarn build
on the worker machine. Obviously, this can be expanded to run any actions you may need.
Linting example:
action "Lint" {
uses = "guahanweb/actions/node-app@master"
env = {
PKG_MANAGER = "yarn"
}
args = "run lint"
}
Several environment variables are availabe to customize the behavior of your actions.
NODE_ENV
- The environment in which to execute your node application.
defaults toproduction
PKG_MANAGER
- Specifies which package manager you are using. Valid values are
npm
andyarn
.
defaults tonpm
This action also offers the ability to easily publish to an orphan branch on your repository. This is generally used for publishing static content to a gh-pages
branch to be hosted by GitHub, but you can customize it to any branching strategy you desire.
This task requires the GITHUB_TOKEN
secret from your action, or it will not have the appropriate permissions to push to your repo.
action "GH Pages" {
uses = "guahanweb/actions/node-app@master"
secrets = ["GITHUB_TOKEN"]
args = "gh-pages"
}
Since every application is different, there are a few overrides you can provide within your env
block to customize behavior.
GITHUB_TOKEN
- This token is provided by GitHub when you specify it in your secrets array. It is required for the operation to have permission to push to your repository.
BUILD_DIR
- Specifies the directory that contains the static assets to be pushed.
defaults tobuild
REMOTE_BRANCH
- Spcifies the branch name to which the contents of
$BUILD_DIR
should be pushed.
defaults togh-pages
The test
operation is provided as an alias to run test
.
Once you have a handle on the options, you can create multiple actions easily and chain them together into a workflow. Here is an example of how you might specify a workflow to lint, test, build, and deploy a GH Pages website using this repository.
workflow "Build and Deploy Pages" {
on = "push"
resolves = ["Lint", "Build", "Test", "Deploy Pages"]
}
action "Lint" {
uses = "guahanweb/actions/node-app@master"
env = {
PKG_MANAGER = "yarn"
}
args = "run lint"
}
action "Build" {
uses = "guahanweb/actions/node-app@master"
env = {
PKG_MANAGER = "yarn"
}
args = "run build"
}
action "Test" {
uses = "guahanweb/actions/node-app@master"
env = {
PKG_MANAGER = "yarn"
}
args = "test"
}
action "Deploy Pages" {
uses = "guahanweb/actions/node-app@master"
secrets = ["GITHUB_TOKEN"]
args = "gh-pages"
needs = ["Lint", "Build", "Test"]
}
