deploy-notify-slack 0.5.9

Dummy script to send notification about new version deployment to a Slack channel

no npm dependencies, plain nodejs 8.x or higher
use Slack incoming webhooks API to send a message
can attach version description Markdown files

Use default message template

You can use default message template with the following env variables:

Required env variables

SLACK_WEBHOOK_URL - you should generate webhook url for your target channel, see: https://api.slack.com/messaging/webhooks
STAGE - name of an application stage you're deploying, usually: dev, staging, prod..
VERSION - deployed version

Optional env variables

TITLE - ('Deployment' by default) notification title
CHANGELOG_PATH - path of your deployed version details file (changelog by default as well as we assume that the package installed locally, so this option is required if the package installed globally)
COLOR - ('#7f8583' by default) left bar notification color. Should be hex color code without # symbol
EMOJI - (':rocket:' by default) emoji to be displayed in the notification title
MAX_BLOCKS - (5 by default) maximum amount of large blocks(2500 symbols) available in slack message. If your changelog is bigger than this value it will be truncated.

version details file is a Markdown file having the name like ${STAGE}-v${VERSION}.md.

you can also create cross-environment file with name pattern v${VERSION}.md and if script cannot find stage specific description it will get this one.

If no description file found details block will be omitted in Slack message.

FAILS_IF_NOT_SENT - (false by default) Should exit with not 0 error code if message was not sent successfully.

How it works

Generate Slack webhook URL https://api.slack.com/messaging/webhooks
In Bitbucket pipeline or another place you wish to notify about just deployed version of your application you can add dev dependency

npm i --no-save deploy-notify-slack@^0.5

or major version

npm i --location=global deploy-notify-slack@^0.5

run the scrypt with your env variables:

SLACK_WEBHOOK_URL=https://hooks.slack.com/services/XXXXXXXXXXX STAGE=dev VERSION=1.0.0 node ./node_modules/deploy-notify-slack/notify

Bitbucket pipeline example:

- step:
    name: Notify deploy
    image: node:16-alpine
    script:
      - npm i --location=global deploy-notify-slack
      - VERSION=$(npm run version --silent)
      - SLACK_WEBHOOK_URL=${SLACK_WEBHOOK_URL} STAGE=dev VERSION=$VERSION node ./node_modules/deploy-notify-slack/notify

or install package globally

- step:
    name: Notify Slack
    image: node:16-alpine
    script:
      - npm i --location=global deploy-notify-slack
      - VERSION=$(npm run version --silent)
      - PWD=$(pwd)
      - SLACK_WEBHOOK_URL=${SLACK_WEBHOOK_URL} STAGE=dev VERSION=$VERSION CHANGELOG_PATH=$PWD/changelog node /usr/local/lib/node_modules/deploy-notify-slack/notify.js

version script above is just a echo $npm_package_version command

Use custom message template

You can specify your own message template instead of default one. It's useful if you want to add some additional information to the message.

Try to use Slack message builder to create your own message template.

Then you should load your template from file and pass it to the script as env variable CUSTOM_MESSAGE:

For example you saved your message template to message.json file:

{
  "blocks": [
    {
      "type": "header",
      "text": {
        "type": "plain_text",
        "text": ":flying_saucer: New API deploy of stage *DEV*",
        "emoji": true
      }
    }
  ]
}

Then you can run the script with the following command:

npm i --location=global deploy-notify-slack@latest
CUSTOM_MESSAGE=$(cat message.json)
SLACK_WEBHOOK_URL=${SLACK_WEBHOOK_URL} CUSTOM_MESSAGE=$CUSTOM_MESSAGE node /usr/local/lib/node_modules/deploy-notify-slack/notify.js
