@atomist/automation-seed

Build Status

This repository contains examples demonstrating use of the Atomist API. You will find examples illustrating:

  • Creating bot commands using command handlers
  • Responding to DevOps events, e.g., commits pushed to a repository, using event handlers

These examples use the @atomist/automation-client node module to implement a local client that connects to the Atomist API.

Prerequisites

Below are brief instructions on how to get started running this project yourself. If you just want to use the functionality this project provides, see the Atomist documentation. For more detailed information on developing automations, see the Atomist Developer Guide.

Slack and GitHub

Atomist automations work best when connected to Slack and GitHub. If you do not have access to a Slack team and/or GitHub organization, it is easy to create your own.

In your Slack team, install the Atomist app in Slack, click the button below.

Add to Slack

Once installed, the Atomist bot will guide you through connecting Atomist, Slack, and GitHub.

If you'd rather not set up your own Slack team and GitHub organization, please reach out to members of Atomist in the #support channel of atomist-community Slack team. You'll receive an invitation to a Slack team and GitHub organization that can be used to explore this new approach to writing and running automations.

The Slack team ID for atomist-playground is T7GMF5USG.

Node.js

You will need to have Node.js installed. To verify that the right versions are installed, please run:

$ node -v
v8.4.0
$ npm -v
5.4.1

The node version should be 8 or greater and the npm version should be 5 or greater.

Cloning the repository and installing dependencies

To get started run the following commands to clone the project, install its dependencies, and build the project:

$ git clone git@github.com:atomist/automation-seed-ts.git
$ cd automation-seed-ts
$ npm install
$ npm run build

Configuring your environment

If this is the first time you will be running an Atomist API client locally, you should first configure your system using the atomist script:

$ `npm bin`/atomist config

The script does two things: records what Slack team you want your automations running in and creates a GitHub personal access token with "repo" and "read:org" scopes.

The script will prompt you for you Slack team ID, or you can supply it using the --slack-team TEAM_ID command-line option. You must run the automations in a Slack team of which you are a member. You can get the Slack team ID by typing team in a DM to the Atomist bot.

The script will prompt you for your GitHub credentials. It needs them to create the GitHub personal access token. Atomist does not store your credentials and only writes the generated token to your local machine.

The Atomist API client authenticates using a GitHub personal access token. The Atomist API uses the token to confirm you are who you say you are and are in a GitHub organization connected to the Slack team in which you are running the automations. In addition, it uses the token when performing any operations that access the GitHub API.

Starting up the automation-client

To start the client, run the following command:

$ npm run autostart

Invoking a command handler from Slack

This project contains the code to create and respond to a simple hello world bot command. The code that defines the bot command and implements responding to the command, i.e., the command handler, can be found in HelloWorld.ts. Once you have your local automation client running (the previous step in this guide), you can invoke the command handler by sending the Atomist bot the command as a message. Be sure the Atomist bot is in the channel before sending it the message.

/invite @atomist
@atomist hello world

Once you've submitted the command in Slack, you'll see the incoming and outgoing messages show up in the logs of your locally running automation-client. Ultimately, you should see the response from the bot in Slack.

Feel free to modify the code in the HelloWorld command handler, Node.js will automatically reload the client, and see what happens!

Triggering an event handler

While command handlers respond to commands you send the Atomist bot, event handlers take action when different types of events occur in your development and operations environment. Some examples of events are commits pushed to a repo, or a CI build that fails, or an instance of a running service that becomes unhealthy. Example responses to those events are showing the commits in a Slack message, automatically restarting the build, and triggering a PagerDuty alert, respectively.

The sample event handler in this project, NotifyOnPush, will notice when someone pushes new commits to a repository in the GitHub organization and send a notice of that push to all Slack channels associated with that repository.

If you have followed the instructions above and are running these automations against the atomist-playground Slack team and GitHub organization, go ahead and edit the notify-on-push repository by adding some text to its README. Once you have saved your changes, you should see that event appear in the console logs of your locally running automation client, followed by a log of the actions the event handler is taking. Once those actions are complete, you should see a new message in the #notify-on-push channel in the atomist-playground Slack team.

Support

General support questions should be discussed in the #support channel in our community Slack team at atomist-community.slack.com.

If you find a problem, please create an issue.

Development

You will need to install node to build and test this project.

Build and Test

Command Reason
npm install install all the required packages
npm run build lint, compile, and test
npm start start the Atomist automation client
npm run autostart run the client, refreshing when files change
npm run lint run tslint against the TypeScript
npm run compile compile all TypeScript into JavaScript
npm test run tests and ensure everything is working
npm run autotest run tests continuously
npm run clean remove stray compiled JavaScript files and build directory

Release

To create a new release of the project, update the version in package.json and then push a tag for the version. The version must be of the form M.N.P where M, N, and P are integers that form the next appropriate semantic version for release. The version in the package.json must be the same as the tag. For example:

$ npm version 1.2.3
$ git tag -a -m 'The ABC release' 1.2.3
$ git push origin 1.2.3

The Travis CI build (see badge at the top of this page) will publish the NPM module and automatically create a GitHub release using the tag name for the release and the comment provided on the annotated tag as the contents of the release notes.
