How can I set up conditional deployments in Travis CI?

How can I set up conditional deployments in Travis CI?

You can use the if condition in your .travis.yml file to set up conditional deployments. For example, you can deploy only when the branch is main.

Can you show me an example of the YAML configuration?

Sure! Here's a simple example:

deploy:
  provider: heroku
  api_key: "${HEROKU_API_KEY}"
  app: my-app
  on:
    branch: main

What if I want to deploy to different environments based on the branch?

You can specify multiple deployment configurations with conditions. For example:

deploy:
  - provider: heroku
    api_key: "${HEROKU_API_KEY}"
    app: my-app
    on:
      branch: main
  - provider: heroku
    api_key: "${HEROKU_API_KEY}"
    app: my-app-staging
    on:
      branch: develop

Is there a way to test the deployment before it goes live?

Yes, you can use a staging environment for testing. Set up a separate deployment for your staging branch and test there before merging to main.
