now-pipeline

Single CI command to deploy new code to Zeit Now Includes e2e tests and the alias switch

First time contributors

This repo is first time OSS contributor friendly. See these issues to contribute in meaningful way.

What and why

I am super excited about Zeit Now tool; this is the "missing CI tool" for it. A single command now-pipeline

• deploys new version
• tests it
• switches alias to the new deployment
• takes down the old deployment

Should be enough to automatically update the server or service running in the cloud without breaking anything.

Install and use

npm i -g now-pipeline

Set NOW_TOKEN CI environment variable with a token that you can get from Zeit account page

Add CI command to now-pipeline. By default it will execute npm test and will pass the deployed url as NOW_URL environment variable. You can customize everything.

Example

Simple Travis commands

script:
  # after unit tests
  - npm i -g now-pipeline
  - now-pipeline

Prune existing deploys (if they do not have an alias) and show the deploy.

script:
  - npm i -g now-pipeline
  - now-pipeline-prune
  - now-pipeline
  - now-pipeline-list

Set domain alias if there is no existing one

script:
  - npm i -g now-pipeline
  - now-pipeline --alias foo.domain.com

Pass in path to be used as deploy directory

script:
  - npm i -g now-pipeline
  - now-pipeline --dir your/directory

Pass test command and name of the environment variable for deployed url

script:
  - npm i -g now-pipeline
  - now-pipeline --as HOST --test "npm run e2e"

Example projects

• todomvc-express
• express-sessions-tutorial
• test-semantic-deploy-with-now

Additional bin commands

• now-pipeline-list - see the current deploys for the current project
• now-pipeline-prune - remove all non-aliased deploys for the current project

You can pass custom test command to the pipeline to be used after deploying fresh install using --test "command" argument. The command will get NOW_URL environment variable with new install. For example

npm i -g now-pipeline
now-pipeline --test "npm run prod-test"

where the package.json has

{
  "scripts": {
    "prod-test": "e2e-test $NOW_URL"
  }
}

Debugging

You can see verbose log messages by running this tool with environment variable DEBUG=now-pipeline

Details
