moon v0.17 - Webhooks, extended YAML, and improved runtime performance

import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';

With this release, we're landing the first iteration of our notifier service, starting with webhooks! We've also spent some time working on quality of life improvements.

Breaking changes

To start, we have a few breaking changes this release to be aware of!

Minor changes to ID formatting

An ID refers to many things — project names, task names, target segments, so on and so forth. When parsing these values, we format them to remove unwanted characters, as these IDs are used in many contexts, many of which need to be strict.

Previously, we would remove unwanted characters entirely. Instead, we now replace them with dashes (-) for better readability. Take the following for example:

Task type has been renamed to platform

This setting was renamed for a few reasons. To start, tasks actually have a type internally that is not configured, but is inferred based on what's configured. This was a bit confusing.

And secondly, our toolchain refers to language integrations as platforms, and since this setting determines which tool to run with, we wanted to align on the platform terminology.

<Tabs groupId="task-type" defaultValue="before" values={[ { label: 'Before', value: 'before' }, { label: 'After', value: 'after' }, ]}

tasks:
  clean:
    command: 'rm -rf ./dist'
    type: 'system'

tasks:
  clean:
    command: 'rm -rf ./dist'
    platform: 'system'

Because of this change, the $taskType token was also renamed to $taskPlatform!

Webhook events (experimental)

Looking to gather metrics for your pipelines? Gain insight into run durations and failures? Maybe you want to send Slack or Discord notifications? With our new notifier system, this is now possible through webhooks!

Simply enable the notifier.webhookUrl setting to start receiving events from your CI environments.

notifier:
  webhookUrl: 'https://api.company.com/some/endpoint'

YAML anchors and aliases

We've updated our YAML configuration files to support extended syntax, anchors (&) and aliases (*). With this new syntax, you're now able to reduce the amount of duplication required in your config files, especially when declaring tasks, as demonstrated below!

<Tabs groupId="yaml" defaultValue="before" values={[ { label: 'Before', value: 'before' }, { label: 'After', value: 'after' }, ]}

tasks:
  astro:
    command: 'astro'
    local: true

  dev:
    command: 'astro dev'
    inputs:
      - '@group(astro)'
    local: true

  build:
    command: 'astro build'
    inputs:
      - '@group(astro)'
    outputs:
      - 'dist'

  check:
    command: 'astro check'
    inputs:
      - '@group(astro)'
    deps:
      - '~:typecheck'

  preview:
    command: 'astro preview'
    inputs:
      - '@group(astro)'
    deps:
      - '~:build'
    local: true

_astro: &astro
  command: 'astro'
  inputs:
    - '@group(astro)'

tasks:
  dev:
    <<: *astro
    args: 'dev'
    local: true

  build:
    <<: *astro
    args: 'build'
    outputs:
      - 'dist'

  check:
    <<: *astro
    args: 'check'

  preview:
    <<: *astro
    args: 'preview'
    deps:
      - '~:build'
    local: true

VS Code extension

If you missed the announcement earlier this week, we released the initial version of our new VS Code extension! Give it a try and refer to the documentation for more information.
