Jarom-Huntsman-DeepSee it's time to get ready for the third action: issue-maker 🎉

As with the other actions we wrote, we are going to need to setup a few directories and files.

Add dependencies for issue-maker action

This time we will start with the dependencies for our action. JavaScript projects can be packaged with a package.json file which contains metadata and configuration information about a project. In our case we will use some pieces of the actions toolkit.

:keyboard: Activity: Add package.json to issue-maker

1. Create and add the following contents to the .github/actions/issue-maker/package.json file: You can use this link to easily create this file.

   {
    "name": "issue-maker",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "dependencies": {
      "@actions/core": "^1.2.2",
      "@actions/github": "^2.1.0"
    }
   }

2. Commit the changes to this branch.

Create the issue-maker's action metadata

Like our "hello world" action, this action will require at least one input: parameter. We need this parameter so that our JavaScript for this action has access to the output: from the joke action.

If you recall, in the my-workflow.yml file, we stated this action would take a specific input named catFact: and we set it's value to the output of the previous action.

- name: create-issue
  uses: ./.github/actions/issue-maker
  with:
    catFact: ${{steps.cat.outputs.fact}}

Because of this, we need to define catFact: as one of our inputs: for this action. Remember when we did this with the first action? It looked a little like this:

inputs:
  catFact:
    description: "the cat fact retreived from a previous action"
    required: true
    default: "Mona is an Octocat"

We also will also need to authenticate to GitHub with the action so that we can interact with the GitHub API. For that we will use a special token that gets created for us when we use actions called GITHUB_TOKEN

Our action will also need to accept an input so that we can let the user specify a name for the issue that will be created when this action runs.

:keyboard: Activity: Add action.yml for issue-maker

💡All of the following steps take place inside of the .github/actions/issue-maker directory.

1. Create and add the following contents to the .github/actions/issue-maker/action.yml file: You can use this link to easily create this file.

   name: "issue maker"
   
   description: "create and issue with a cat fact as the body"
   
   inputs:
    issueTitle:
      description: "A name for the cat-fact issue"
      required: true
      default: "A cat fact for you"
   
    catFact:
      description: "the cat fact retreived from a previous action"
      required: true
      default: "Mona is an Octocat"
   
    repoToken:
      description: "Authentication token, use secrets.GITHUB_TOKEN"
      required: true
   
   runs:
    using: "docker"
    image: "Dockerfile"

Add the issue-maker action's source code

:keyboard: Activity: Add src/index.js for issue-maker

💡All of the following steps take place inside of the .github/actions/issue-maker/src directory.

1. Create and add the following contents to the .github/actions/issue-maker/src/index.js file: You can use this link to easily create this file.

   const core = require("@actions/core");
   const github = require("@actions/github");
   
   async function run() {
    const issueTitle = core.getInput("issueTitle");
    const catFact = core.getInput("catFact");
   
    const token = core.getInput("repoToken");
    try {
      const octokit = new github.GitHub(token);
   
      const newIssue = await octokit.issues.create({
        repo: github.context.repo.repo,
        owner: github.context.repo.owner,
        title: issueTitle,
        body: catFact
      });
    } catch (error) {
      core.setFailed(error.message);

Trigger all the things 🎉

Let's trigger your new workflow!

1. Add a label to this pull request, it can be any label you choose.
2. After adding a label head over to your Actions tab if you want to watch the workflow.
3. Once your workflow has completed check your issues tab and you should see a new issue with a cat fact as the body!

Continue experimenting with this workflow for as long as you'd like.

Try adding another label and see if you get a new fact!

When you have finished experimenting, merge this pull request and meet me in this issue to finish wrapping things up.
